+# Tool commands
+
+OceanBase Deployer (OBD) provides a series of tool commands, including general commands that deliver a better experience for developers.
+
+## obd devmode enable
+
+You can run this command to enable the developer mode, which is a prerequisite for using other tool commands. After you enable the developer mode, OBD will downgrade the level of some exceptions and ignore some parameter exceptions. If you are not a kernel developer, use this command with caution.
+
+```shell
+obd devmode enable
+```
+
+## obd devmode disable
+
+You can run this command to disable the developer mode.
+
+```shell
+obd devmode disable
+```
+
+## obd env show
+
+You can run this command to display the environment variables of OBD.
+
+```shell
+obd env show
+```
+
+## obd env set
+
+You can run this command to set the environment variables of OBD. Environment variables can affect the performance of OBD. Therefore, we recommend that you use this command only when it is necessary.
+
+```shell
+obd env set [key] [value]
+```
+
+You can set the following variables:
+
+* `OBD_DISABLE_RSYNC`: OBD allows you to run the `rsync` command for remote data transmission when the prerequisites are met. If this environment variable is set to `1`, the `rsync` command is disabled. Valid values: `0` and `1`.
+
+* `OBD_DEV_MODE`: specifies whether to enable the developer mode. Valid values: `0` and `1`.
+
+## obd env unset
+
+You can run this command to delete the specified environment variable.
+
+```shell
+obd env unset [key] [value]
+```
+
+## obd env clear
+
+You can run this command to clear environment variables of OBD. Use this command with caution.
+
+```shell
+obd env clear
+```
+
+## obd tool command
+
+You can use this command to run some general commands.
+
+```shell
+obd tool command <deploy name> <command> [options]
+```
+
+Valid values of the `command` field:
+
+* `pid`: allows you to view the process ID (PID) of a service. This is a non-interactive command.
+
+* `ssh`: allows you to log on to the specified server and enter the log directory. This is an interactive command.
+
+* `less`: allows you to view the logs of the specified service. This is an interactive command.
+
+* `gdb`: allows you to attach GNU Debugger (GDB) to a template service. This is an interactive command.
+
+The following table describes the options of the command.
+
+| Option | Required | Data type | Default value | Description |
+|-----------------|------|--------|-------------------------------------------------------|---------------------------|
+| -c/--components | No | String | In an interactive command, the first component specified in the configuration file is used by default. In a non-interactive command, all components are used. | The name of the component on which the command is executed. Separate multiple component names with commas (`,`).  |
+| -s/--servers | No | String | In an interactive command, the first node of the current component specified in the configuration file is used by default. In a non-interactive command, all available nodes are used. | The name of the node under the specified component. Separate multiple node names with commas (`,`).  |
+
+## obd tool db_connect
+
+You can run this command to create a connection to the database.
+
+```shell
+obd tool db_connect <deploy name> [options]
+```
+
+The `deploy name` parameter indicates the name of the deployed cluster, which is also the alias of the configuration file.
+
+The following table describes the options of the command.
+
+| Option | Required | Data type | Default value | Description |
+|---------------------|------|--------|---------------------------|-------------------------------------------------------------------|

+
+## How do I upgrade an OBProxy to obproxy-ce 3.2.3?
+
+The open source OBProxy component is formally renamed as obproxy-ce after v3.2.3. Therefore, you need to modify the metadata as the execution user of OBD. For more information, see [Execute the script] (2.how-to-upgrade-obproxy-to-obproxy-ce-3.2.3.md). Then, run the following command for upgrade:
+
+```shell
+obd cluster upgrade <deploy name> -c obproxy-ce -V 3.2.3
+```
+
+## What should I do if an exception occurs when I use OBD to upgrade an OBProxy?
+
+The following problem may occur during the upgrade of OBProxy:
+
+```bash
+Stop obproxy ok
+Start obproxy ok
+obproxy program health check ok
+Connect to obproxy x
+```
+
+The problem indicates that OBD cannot connect to the OBProxy, the reason may be either of the following:
+
+1. The access from other IP addresses except 127.0.0.1 is disabled by proxysys. As a result, the OBD server cannot establish a connection. In this case, run the following command to connect to proxysys:
+
+   ```bash
+   obclient -h<obproxy_ip> -uroot@proxysys -P<obproxy_post> -p<obproxy_pwd>
+   ```
+
+   > **Note**
+   >
+   > If the connection fails with a password set by yourself, change the password to empty or to `proxysys`.
+
+   Then, run the `alter proxyconfig set skip_proxy_sys_private_check = true` command.
+
+2. The password of proxysys is inconsistent with the one stored in OBD. In this case, run the corresponding command to connect to proxysys, and then run the `alter proxyconfig set obproxy_sys_password = <obproxy_pwd>` command to change the password of proxysys.
+
+   You can change the password to empty (`obproxy_sys_password = ''`) or to the password stored in the configuration file of OBD.
+
+If the problem persists, submit an issue on GitHub (<https://github.com/oceanbase/obdeploy/issues>), and designated professionals will help you fix the issue.
+
+## What should I do if the OBProxy service cannot be started after OBD is upgraded?
+
+An OBD upgrade will initialize the OBProxy password. If `obproxy_sys_password` is specified, run the following command to connect to proxysys:
+
+```bash
+obclient -h<obproxy_ip> -uroot@proxysys -P<obproxy_post> -p<obproxy_pwd>
+```
+
+> **Note**
+>
+> If the connection fails with a password set by yourself, change the password to empty or to `proxysys`.
+
+Then, run the `alter proxyconfig set obproxy_sys_password = ''` command to set the password of proxysys to empty, or set the password to the one specified by `obproxy_sys_password` in the configuration file.

+# Error codes
+
+This topic summarizes the errors that may occur during the use of OBD.
+
+## General errors
+
+### OBD-1000: Configuration conflict x.x.x.x: xxx port is used for x.x.x.x
+
+Cause: Port conflicts occur in the configuration file.
+
+Solution: Check and modify the configuration.
+
+### OBD-1001: x.x.x.x:xxx port is already used
+
+Cause: The port has been occupied.
+
+Solution: Check the configuration and change the port.
+
+### OBD-1002: Fail to init x.x.x.x path
+
+Cause:
+
+1. `user` in the configuration file (the current user by default, if unspecified) does not have the write permission on the corresponding directory.
+  
+2. home_path is not empty.
+
+You can determine the cause based on the error information.
+
+Solution:
+
+For case 1, you can resolve the problem in two ways.
+
+- Run the following command to add or modify `user` information:
+  
+  ```shell
+  obd cluster edit-config <deploy name>
+  ```
+
+- Log on to the target server and grant the current account the write permission on the corresponding directory.
+
+For case 2, you can also resolve the problem in two ways.
+
+- Select another directory.
+  
+- If you are sure that the current directory can be cleared, you can use the `-f` option. OBD will clear this directory by using the current user.
+
+### OBD-1003: fail to clean x.x.x.x:xxx
+
+Cause: `user` in the configuration file (the current user by default, if unspecified) does not have the write permission on the home_path directory.
+
+Solution: You can resolve the problem in two ways.
+
+- Run the following command to add or modify `user` information:
+  
+  ```shell
+  obd cluster edit-config <deploy name>
+  ```
+
+- Log on to the target server and grant the current account the write permission on the corresponding directory.
+
+### OBD-1004: Configuration conflict x.x.x.x: xxx is used for x.x.x.x
+
+Cause: Path conflicts occur in the configuration file.
+
+Solution: Check and modify the configuration.
+
+### OBD-1005: Some of the servers in the cluster have been stopped
+
+Cause: Some servers in the current configuration have been stopped, but subsequent operations require the services of all servers to be online.
+
+Solution: Run the `obd cluster start <deploy_name> --wop` command to start all services without loading parameters.
+
+### OBD-1006: Failed to connect to xxx
+
+Cause:
+
+1. OceanBase Deployer (OBD) and the specified server are disconnected.
+
+2. The corresponding component process has exited or does not provide service.
+
+3. The account and password do not match.
+
+Solution:
+
+If the error is due to cause 1, you need to solve the network connection issue.
+
+If the error is due to cause 2, you can try restarting the component first. If the startup still fails, please refer to the error of startup failure for troubleshooting, such as **OBD-2002**.
+
+If the error is due to cause 3, it is likely that you have changed the password by executing SQL statements, and the account password is different from that stored in the configuration file. As a result, OBD cannot connect to the component. In this case, you can use any of the following two solutions:
+
+1. Execute SQL statements to change the password back to that stored in the configuration file of OBD.
+
+2. Run the `vi ~/.obd/cluster/<deploy name>/config.yaml` command to change the password to the one that is in use for the component.
+
+### OBD-1007: (x.x.x.x) xxx must not be less than xxx (Current value: xxx)
+
+Cause: The configuration of the ulimit parameter does not meet the requirements.
+
+Solution: You can modify the corresponding files in the /etc/security/limits.d/ directory and the limits.conf file in the /etc/security/ directory as needed.
+
+## OceanBase deployment errors
+
+### OBD-2000: x.x.x.x not enough memory
+
+Cause: The memory is insufficient.
+
+Solution: When OBD starts, the memory is strictly calculated based on MemAvailable. If any cached memory can be released, run the following command:
+
+```shell
+echo 3 > /proc/sys/vm/drop_caches
+```
+
+If the memory is still insufficient, run `edit-config` and then adjust `memory_limt` and `system_memory`. Ensure that the following condition is met: `memory_limt/3 ≤ system_memory ≤ memory_limt/2`.
+
+> **Note**
+>
+> `memory_limt` cannot be lower than 8 GB. In other words, your available memory must be greater than 8 GB.
+
+### OBD-2001: server can not migrate in
+
+Cause: The number of available units is smaller than `--unit-num`.
+
+Solution: Modify the passed value of `--unit-num`. Run the following command to view the number of available units:
+
+```sql
+select count(*) num from oceanbase.__all_server where status = 'active' and start_service_time > 0
+```
+
+### OBD-2002: failed to start x.x.x.x observer
+
+Cause: There are multiple causes for this error. Two most common causes are as follows.
+
+- `memory_limit` is lower than 8 GB.
+
+- `system_memory` is too large or small. Generally, the following condition must be met: `memory_limt/3 ≤ system_memory ≤ memory_limt/2`.
+
+Solution:
+
+- If the problem is caused by either of the preceding reasons, take actions accordingly.
+
+- If the problem persists, submit an issue on GitHub (<https://github.com/oceanbase/obdeploy/issues>), and designated professionals will help you fix the issue.
+
+### OBD-2003: not enough disk space for clog. Use redo_dir to set other disk for clog, or reduce the value of datafile_size
+
+Cause: The disk usage exceeds the limit.
+
+Solution: Adjust the storage of disks.
+
+- For automatic deployment, the disk usage cannot exceed 72%.
+  
+- For manual deployment, the disk usage cannot exceed 64%, if the configuration is not modified.
+
+> **Note**
+>
+> If redo_dir and data_dir are on the same disk, the space to be occupied by data files is included when the disk usage is calculated.
+
+### OBD-2004: Invalid: xxx is not a single server configuration item
+
+Cause: The modified parameter is a global one and cannot be separately modified for a single server.
+
+Solution: Place the parameter to modify under global.
+
+## Test errors
+
+### OBD-3000: parse cmd failed
+
+Cause: The mysqltest initialization file is not an `.sql` file.
+
+Solution: Check the `--init-sql-files` parameter.
+
+### OBD-3001: xxx.sql not found
+
+Cause: The initialization file cannot be found during the initialization of mysqltest.
+
+Solution: Check whether the file declared by `--init-sql-files` is located under the `--init-sql-dir` directory.
+
+### OBD-3002: Failed to load data
+
+Cause: There are multiple causes for this error. Two most common causes are as follows.
+
+1. The tenant has insufficient resources or is under excessive test stress.
+
+2. An error occurred in the data build script.
+
+Solution:
+
+If the error is due to cause 1, you can use a tenant with larger resource specifications or adjust parameters such as warehouses and load-workers to reduce the test stress.
+
+If the error is due to cause 2, you can rerun the test because the data build script is obtained from the TPC official website. If the issue persists, submit an issue on GitHub (<https://github.com/oceanbase/obdeploy/issues>), and designated professionals will help you fix the issue.
+
+### OBD-3003: Failed to run TPC-C benchmark
+
+Cause:
+
+1. The test process was stuck and then terminated due to timeout.
+
+2. An error occurred for the TPC-C test command.
+
+Solution:
+
+- You can try to rerun the test directly, or you can adjust parameters such as terminals to reduce the test pressure before you rerun the test.
+
+- If you did not use the obtpcc package provided on the OceanBase Database official website, use obtpcc for testing.
+
+If the issue persists, submit an issue on GitHub (<https://github.com/oceanbase/obdeploy/issues>), and designated professionals will help you fix the issue.
+
+## OBAgent errors
+
+### OBD-4000: Fail to reload x.x.x.x
+
+Cause: The `http_basic_auth_password` of the node is not the same as that stored in OBD, which causes OBD to fail to access OBAgent.
+
+Solution: If the two passwords are the same, check whether an unsupported parameter is included among the modified options, or whether the name of a parameter is incorrect.
+
+### OBD-4001: Fail to send config file to x.x.x.x
+
+Cause: (Check whether the error is caused by either of the reasons.)
+
+- The disk space for the home_path directory on OBAgent is insufficient.
+
+- `user` in the configuration file (the current user by default, if unspecified) does not have the write permission on the home_path directory on OBAgent.
+
+Solution: You can resolve the problem in two ways.
+
+- Run the following command to add or modify `user` information:
+  
+  ```shell
+  obd cluster edit-config <deploy name>
+  ```
+
+- Log on to the target server and grant the current account the write permission on the corresponding directory.

+# 工具命令组
+
+OBD 提供了一系列工具命令，其中封装了一些常用命令，可用于提升开发者的使用体验。
+
+## obd devmode enable
+
+使用该命令可以开启开发者模式，是使用工具命令组的前提。开启开发者模式后，会出现部分异常报错被降级，OBD 忽略异常参数等情况。非内核开发人员请谨慎使用。
+
+```shell
+obd devmode enable
+```
+
+## obd devmode disable
+
+使用该命令可关闭开发者模式。
+
+```shell
+obd devmode disable
+```
+
+## obd env show
+
+使用该命令可展示 OBD 的环境变量。
+
+```shell
+obd env show
+```
+
+## obd env set
+
+使用该命令可设置 OBD 的环境变量，这些环境变量会一定程度的影响 OBD 的表现，若没有特别需求不建议使用该命令。
+
+```shell
+obd env set [key] [value]
+```
+
+可设置的参数有：
+
+* OBD_DISABLE_RSYNC：参数值可设置为 0 或 1，在符合条件的情况下 OBD 会使用 rsync 进行远程传输，当该环境变量为 1 时，禁止使用 rsync 命令。
+
+* OBD_DEV_MODE：：开发者模式是否开启，可选值为 0 或 1。
+
+## obd env unset
+
+使用该命令可删除指定环境变量。
+
+```shell
+obd env unset [key] [value]
+```
+
+## obd env clear
+
+使用该命令可清理 OBD 的环境变量，请谨慎使用。
+
+```shell
+obd env clear
+```
+
+## obd tool command
+
+使用该命令可执行一些常用的命令。
+
+```shell
+obd tool command <deploy name> <command> [options]
+```
+
+命令包含：

+# 使用 OCP 接管 OBD 部署的集群
+
+本文将以一个使用配置文件 distributed-example.yaml 启动的 test 部署为例，介绍如何使用 OCP 接管 OBD 部署的集群。
+
+## 前提条件
+
+- 请确保您安装的 OBD 版本在 V1.3.0 及以上。
+  
+- 请确保您安装的 OCP 版本在 V3.1.1-ce及以上。
+
+## 修改 OceanBase 集群
+
+### 检查是否满足条件
+
+在使用 OCP 接管 OBD 部署的集群前，您需先使用如下命令检查是否满足接管条件。如条件不满足，则可以根据提示参考下文进行修改。
+
+```shell
+obd cluster check4ocp <deploy-name>
+
+# 示例
+obd cluster check4ocp test
+```
+
+有关 `obd cluster check4ocp` 命令的具体信息请参考 [obd cluster check4ocp](3.obd-command/1.cluster-command-groups.md)。
+
+### 设置 IDC 信息
+
+默认风格的配置文件不支持配置 IDC 信息，因此需要使用 OBD 1.3.0 版本的新功能，将配置文件风格转换成 cluster 风格。
+
+您可使用如下命令进行转换：
+
+```shell
+obd cluster chst <deploy name> --style <STYLE> [-c/--components]
+
+# 示例
+obd cluster chst test -c oceanbase-ce --style cluster
+```
+
+有关 `obd cluster chst` 命令的具体信息请参考 [obd cluster chst](3.obd-command/1.cluster-command-groups.md)。
+
+配置风格文件转换完成后，您需使用如下命令进入到编辑模式为 Zone 添加 IDC 信息。
+
+```shell
+obd cluster edit-config <deploy name>
+
+# 示例
+obd cluster edit-config test
+```
+
+有关 `obd cluster edit-config` 命令的具体信息请参考 [obd cluster edit-config](3.obd-command/1.cluster-command-groups.md)。
+
+参考配置如下：
+
+```yaml
+## Only need to configure when remote login is required
+# user:
+#   username: your username
+#   password: your password if need
+#   key_file: your ssh-key file path if need
+#   port: your ssh port, default 22
+#   timeout: ssh connection timeout (second), default 30
+oceanbase-ce:
+  style: cluster
+  config:
+    devname: eth0

+    enable_syslog_wf: false
+    enable_syslog_recycle: true
+    max_syslog_file_count: 4
+    skip_proxy_sys_private_check: true
+    enable_strict_kernel_release: false
+    mysql_port: 2881
+    rpc_port: 2882
+    home_path: /root/observer
+    root_password: xxxxxx
+  zones:
+    zone1:
+      idc: idc1
+      servers:
+      - name: server1
+        ip: xxx.xxx.xxx.xxx
+    zone2:
+      idc: idc2
+      servers:
+      - name: server2
+        ip: xxx.xxx.xxx.xxx
+    zone3:
+      idc: idc3
+      servers:
+      - name: server3
+        ip: xxx.xxx.xxx.xxx
+```
+
+配置文件修改后，您需运行如下命令使改动生效。
+
+```shell
+obd cluster reload <deploy name>
+
+# 示例
+obd cluster reload test
+```
+
+有关 `obd cluster reload` 命令的具体信息请参考 [obd cluster reload](3.obd-command/1.cluster-command-groups.md)。
+
+### 配置密码
+
+使用 OCP 接管集群时需要填写 sys 租户下 root 用户连接集群的密码，您可使用如下命令编辑配置文件，并使用 `root_passwd` 来配置密码。
+
+```shell
+obd cluster edit-config <deploy name>
+
+# 示例
+obd cluster edit-config test
+```
+
+部分配置文件示例如下：
+
+```yaml
+## Only need to configure when remote login is required
+# user:
+#   username: your username
+#   password: your password if need
+#   key_file: your ssh-key file path if need
+#   port: your ssh port, default 22
+#   timeout: ssh connection timeout (second), default 30
+oceanbase-ce:
+servers:
+    - name: server1
+    # Please don't use hostname, only IP can be supported
+    ip: xxx.xxx.xxx.xxx
+    - name: server2
+    ip: xxx.xxx.xxx.xxx
+    - name: server3
+    ip: xxx.xxx.xxx.xxx
+global:
+    # The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
+    home_path: /root/observer
+    # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
+    mysql_port: 2881
+    # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.
+    rpc_port: 2882
+    # The maximum running memory for an observer. When ignored, autodeploy calculates this value based on the current server available resource.
+    memory_limit: 64G 
+    # The reserved system memory. system_memory is reserved for general tenants. The default value is 30G. Autodeploy calculates this value based on the current server available resource.
+    system_memory: 30G
+    # Password for root. The default value is empty.
+    root_password: xxxxxx
+    # Password for proxyro. proxyro_password must be the same as observer_sys_password. The default value is empty.
+    # proxyro_password:
+server1:
+    zone: zone1
+server2:
+    zone: zone2
+server3:
+    zone: zone3
+```
+
+上述为默认风格的配置文件示例，cluster 风格的配置文件请参考上文 **设置 IDC 信息** 中的配置示例。
+
+配置文件修改后，您需运行如下命令使改动生效。
+
+```shell
+obd cluster reload <deploy name>
+
+# 示例
+obd cluster reload test
+```
+
+### 修改用户
+
+OCP 要求进程必须是使用 admin 用户启动，且 admin 用户需要有免密 sudo 的权限。因此我们需要准备好可以免密 sudo 的 admin 用户。如果你已经满足此条件可以直接参考下文 **更改用户** 进行操作。
+
+#### 创建用户
+
+您可使用 root 用户参考如下操作在部署了 OBServer 的机器中创建 admin 用户。
+
+```shell
+# 创建用户组
+groupadd admin
+# 创建用户
+useradd admin -g admin
+```
+
+创建 admin 用户后，您需为 admin 用户配置免密登录。有关如何配置免密 SSH 登录，详情请参考 [设置无密码 SSH 登录](https://www.oceanbase.com/docs/community-observer-cn-0000000000160095)。
+
+> **注意**
+>
+> 1. 您需要为 admin 用户配置 SSH 免密登录。
+>
+> 2. 这里需要配置的为私钥，即 `id_rsa`。
+
+#### 免密 sudo
+
+以下操作请在 root 用户下进行:
+
+```yaml
+# 添加 sudoers 文件的写权限
+chmod u+w /etc/sudoers
+# vi /etc/sudoers
+echo 'admin ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
+# 撤销 sudoers 文件写权限
+chmod u-w /etc/sudoers
+```
+
+#### 更改用户
+
+您可使用如下命令进入编辑模式修改 user 字段。
+
+```shell
+obd cluster edit-config <deploy name>
+
+# 示例
+obd cluster edit-config test
+```
+
+修改后的配置示例：
+
+```yaml
+## Only need to configure when remote login is required
+user:
+  username: admin
+#   password: your password if need 
+  key_file: your ssh-key file path if need # 设置为 admin 的 id_rsa 文件路径
+#   port: your ssh port, default 22
+#   timeout: ssh connection timeout (second), default 30
+```
+
+修改配置文件后，您需使用如下命令使改动生效。
+
+```shell
+obd cluster restart <deploy name>
+
+# 示例
+obd cluster restart test --wp
+```
+
+有关 `obd cluster restart` 命令的具体信息请参考 [obd cluster restart](3.obd-command/1.cluster-command-groups.md)。
+
+### 单机多 Server
+
+OCP 要求一个台机器只能有一个 OBServer，目前没有适配单机多 Server 的场景。如果需要 OCP 接管单机多 Server 的集群，您需手动停止其他的 OBServer，保证一台机器只有一个 OBServer 在运行。
+
+> **说明**
+>
+> 上述所有操作完成后，您可再次执行 `obd cluster check4ocp <deploy name>` 命令检查是否满足接管条件，若条件不满足，则可以根据提示进行修改。
+
+## 使用 OCP 接管集群
+
+### 处理 proxyro 密码
+
+在 OCP 接管集群之前，需要确认待接管集群中的 proxyro 用户的密码，如果该密码非默认值，则需将 OCP 中的 proxyro 密码修改为待接管集群中的 proxyro 用户的密码。
+
+您可调用 OCP API 进行修改
+
+```bash
+curl --user user:pass -X POST "http://ocp-site-url:port/api/v2/obproxy/password" -H "Content-Type:application/json" -d '{"username":"proxyro","password":"*****"}'
+
+```
+
+说明：
+
+- `user:pass` 分别为 OCP 的用户和密码，并且要求调用的用户需要有 admin 权限。
+  
+- `-d` 参数后面的 `password` 为待接管集群的 proxyro 用户的密码。
+
+该操作会生成运维任务，将 OCP 中现有 Oceanbase 集群的 proxyro 密码修改，同时修改 OBProxy 集群对应的配置。
+
+您需等运维任务成功结束后才可进行后述步骤，如果任务失败，则需要重试并将任务执行成功之后才能执行后面的步骤。
+
+![任务示例](https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/doc/img/obd/V1.3.0/zh-CN/4.configuration-file-description-01.png)
+
+### OCP 接管 OceanBase 集群
+
+您可直接在 OCP 的白屏页面进行接管 OceanBase 集群的操作，具体步骤请参考 [接管集群](https://www.oceanbase.com/docs/community-ocp-cn-10000000000407628)。
+
+使用 OCP 接管 OceanBase 集群后，您需新建 OBProxy 集群并关联接管的 OceanBase 集群，具体步骤请参考 [创建 OBProxy 集群](https://www.oceanbase.com/docs/community-ocp-cn-10000000000407609)。
+
+如果原 OBProxy 使用了 VIP，可以将 OCP 上新建的 OBProxy 逐个添加到 VIP 中，再逐个从 VIP 中下线原 OBProxy。
+
+### FAQ
+
+1. 为什么要修改 OCP 中的 proxyro 账号的密码？
+
+   因为 OCP 中管理的 OBProxy 一般是通过 configserver 拉起的，设计上是可以连接多个 OceanBase 集群，但是 OBProxy 只能全局的修改 proxyro 的用户密码，所以这个配置在 OCP 中是一个全局的配置，proxyro 用户的密码仅用来让 OBProxy 查询一些元数据，修改并不影响业务租户。
+
+2. 切换新的 OBProxy，可以复用原来的机器吗？
+
+   如果原来部署了多台 OBProxy 并且通过 VIP 来访问，可以逐个下线，并且用相同的机器在 OCP 中部署 OBProxy，再添加回 VIP，通过这种方式实现机器复用。
+
+3. 不切换 OBProxy 是否可以？
+
+   可以的，原 OBProxy 仍然可以正常连接接管的 OceanBase 集群，但是还是建议用 OCP 新建 OBProxy 进行替换，方便以后的运维管理。

+
+   之后执行 `alter proxyconfig set skip_proxy_sys_private_check = true` 命令。
+
+2. proxysys 的密码与 OBD 中存储的不一致，这种情况下请先执行上述命令连接到 proxysys ，之后执行命令 `alter proxyconfig set obproxy_sys_password = <obproxy_pwd>` 修改 proxysys 密码。
+
+   您可将其密码修改为空（即 `obproxy_sys_password = ''`），或使其与 OBD 配置文件中存储的密码一致。

+# 如何升级 obproxy 到 obproxy-ce 3.2.3
+
+由于开源 OBProxy 组件正式更名为 obproxy-ce，因此使用以下命令升级会报 `No such package obproxy-3.2.3` 错误。
+
+```shell
+obd cluster upgrade <deploy name> -c obproxy -V 3.2.3
+```
+
+您需在 OBD 的执行用户下执行下述 **脚本** 修改 meta 信息，而后使用以下命令对 OBProxy 进行升级。
+
+```shell
+obd cluster upgrade <deploy name> -c obproxy-ce -V 3.2.3
+```
+
+## 脚本

+# os_collector_linux.py -
+#
+#   Script used to collect OS level resource utilization data like
+#   CPU usage and disk IO.
+#
+#   This code is used in the jTPCCOSCollect class. It is launched as
+#   a separate process, possibly via ssh(1) on the remote database
+#   server. The ability of Python to receive a script to execute on
+#   stdin allows us to execute this script via ssh(1) on the database
+#   server without installing any programs/scripts there.
+#
+#   The command line arguments for this script are the runID, the
+#   interval in seconds at which to collect information and a variable
+#   number of devices in the form "blk_<devname>" "net_<devname>",
+#   for example "blk_sda" for the first SCSI disk or "net_eth0".
+#
+#   The output on stdout is one line for CPU/VM info, followed by a
+#   line for each of the specified devices in CSV format. The first
+#   set of lines are the CSV headers. The output is prefixed with the
+#   runID, elapsed_ms and for the devices the blk_ or net_ name that
+#   was specified on the command line. This format makes it easy to
+#   load the data into a result database where it can be analyzed
+#   together with the BenchmarkSQL per transaction results and compared
+#   to other benchmark runs.
+#
+#   It is the caller's responsibility to split the output lines into
+#   separate result CSV files.
