#集群安装、管理
多个taosd的运行实例可以组成一个集群，以保证TDengine的高可靠运行，并提供水平扩展能力。要了解TDengine 2.0的集群管理，需要对集群的基本概念有所了解，请看TDengine 2.0整体架构一章。
集群的每个节点是由End Point来唯一标识的，End Point是由FQDN(Fully Qualified Domain Name)外加Port组成，比如 h1.taosdata.com:6030。一般FQDN就是服务器的hostname，可通过Linux命令“hostname"获取。端口是这个节点对外服务的端口号，缺省是6030，但可以通过taos.cfg里配置参数serverPort进行修改。
TDengine的集群管理极其简单，除添加和删除节点需要人工干预之外，其他全部是自动完成，最大程度的降低了运维的工作量。本章对集群管理的操作做详细的描述。
##安装、创建第一个节点
集群是由一个一个dnode组成的，是从一个dnode的创建开始的。创建第一个节点很简单，就按照["立即开始“](https://www.taosdata.com/cn/getting-started/)一章的方法进行安装、启动即可。
启动后，请执行taos, 启动taos shell，从shell里执行命令"show dnodes;"，如下所示：
```
Welcome to the TDengine shell from Linux, Client Version:2.0.0.0
Copyright (c) 2017 by TAOS Data, Inc. All rights reserved.
taos> show dnodes;
id | end_point | vnodes | cores | status | role | create_time |
=====================================================================================
1 | h1.taos.com:6030 | 0 | 2 | ready | any | 2020-07-31 03:49:29.202 |
Query OK, 1 row(s) in set (0.006385s)
taos>
```
上述命令里，可以看到这个刚启动的这个节点的End Point是：h1.taos.com:6030
## 安装、创建后续节点
将新的节点添加到现有集群，具体有以下几步：
1. 按照["立即开始“](https://www.taosdata.com/cn/getting-started/)一章的方法进行安装，但不要启动taosd
2. 如果是使用涛思数据的官方安装包进行安装，在安装结束时，会询问集群的End Port, 输入第一个节点的End Point即可。如果是源码安装，请编辑配置文件taos.cfg(缺省是在/etc/taos/目录)，增加一行：
```
firstEp h1.taos.com:6030
```
请注意将示例的“h1.taos.com:6030" 替换为你自己第一个节点的End Point
3. 按照["立即开始“](https://www.taosdata.com/cn/getting-started/)一章的方法启动taosd
4. 在Linux shell里执行命令"hostname"找出本机的FQDN, 假设为h2.taos.com。如果无法找到，可以查看taosd日志文件taosdlog.0里前面几行日志(一般在/var/log/taos目录)，fqdn以及port都会打印出来。
5. 在第一个节点，使用CLI程序taos, 登录进TDengine系统, 使用命令:
```
CREATE DNODE "h2.taos.com:6030";
```
将新节点的End Point添加进集群的EP列表。**"fqdn:port"需要用双引号引起来**，否则出错。请注意将示例的“h2.taos.com:6030" 替换为你自己第一个节点的End Point
6. 使用命令
```
SHOW DNODES;
```
查看新节点是否被成功加入。
按照上述步骤可以源源不断的将新的节点加入到集群。
**提示：**
- firstEp, secondEp这两个参数仅仅在该节点第一次加入集群时有作用，加入集群后，该节点会保存最新的mnode的End Point列表，不再依赖这两个参数。
- 两个没有配置first, second参数的dnode启动后，会独立运行起来。这个时候，无法将其中一个节点加入到另外一个节点，形成集群。**无法将两个独立的集群合并成为新的集群**。
##节点管理
###添加节点
执行CLI程序taos, 使用root账号登录进系统, 执行:
```
CREATE DNODE "fqdn:port";
```
将新节点的End Point添加进集群的EP列表。**"fqdn:port"需要用双引号引起来**，否则出错。一个节点对外服务的fqdn和port可以通过配置文件taos.cfg进行配置，缺省是自动获取。
###删除节点
执行CLI程序taos, 使用root账号登录进TDengine系统，执行：
```
DROP DNODE "fqdn:port";
```
其中fqdn是被删除的节点的FQDN，port是其对外服务器的端口号
###查看节点
执行CLI程序taos,使用root账号登录进TDengine系统，执行：
```
SHOW DNODES;
```
它将列出集群中所有的dnode,每个dnode的fqdn:port, 状态(ready, offline等），vnode数目，还未使用的vnode数目等信息。在添加或删除一个节点后，可以使用该命令查看。
如果集群配置了Arbitrator，那么它也会在这个节点列表中显示出来，其role列的值会是“arb”。
###查看虚拟节点组
为充分利用多核技术，并提供scalability，数据需要分片处理。因此TDengine会将一个DB的数据切分成多份，存放在多个vnode里。这些vnode可能分布在多个dnode里，这样就实现了水平扩展。一个vnode仅仅属于一个DB，但一个DB可以有多个vnode。vnode的是mnode根据当前系统资源的情况，自动进行分配的，无需任何人工干预。
执行CLI程序taos,使用root账号登录进TDengine系统，执行：
```
SHOW VGROUPS;
```
##高可用性
TDengine通过多副本的机制来提供系统的高可用性。副本数是与DB关联的，一个集群里可以有多个DB，根据运营的需求，每个DB可以配置不同的副本数。创建数据库时，通过参数replica 指定副本数（缺省为1）。如果副本数为1，系统的可靠性无法保证，只要数据所在的节点宕机，就将无法提供服务。集群的节点数必须大于等于副本数，否则创建表时将返回错误“more dnodes are needed"。比如下面的命令将创建副本数为3的数据库demo：
```
CREATE DATABASE demo replica 3;
```
一个DB里的数据会被切片分到多个vnode group，vnode group里的vnode数目就是DB的副本数，同一个vnode group里各vnode的数据是完全一致的。为保证高可用性，vnode group里的vnode一定要分布在不同的dnode里（实际部署时，需要在不同的物理机上），只要一个vgroup里超过半数的vnode处于工作状态，这个vgroup就能正常的对外服务。
一个dnode里可能有多个DB的数据，因此一个dnode离线时，可能会影响到多个DB。如果一个vnode group里的一半或一半以上的vnode不工作，那么该vnode group就无法对外服务，无法插入或读取数据，这样会影响到它所属的DB的一部分表的d读写操作。
因为vnode的引入，无法简单的给出结论：“集群中过半dnode工作，集群就应该工作”。但是对于简单的情形，很好下结论。比如副本数为3，只有三个dnode，那如果仅有一个节点不工作，整个集群还是可以正常工作的，但如果有两个节点不工作，那整个集群就无法正常工作了。
##Mnode的高可用
TDengine集群是由mnode (taosd的一个模块，逻辑节点) 负责管理的，为保证mnode的高可用，可以配置多个mnode副本，副本数由系统配置参数numOfMnodes决定，有效范围为1-3。为保证元数据的强一致性，mnode副本之间是通过同步的方式进行数据复制的。
一个集群有多个dnode, 但一个dnode至多运行一个mnode实例。多个dnode情况下，哪个dnode可以作为mnode呢？这是完全由系统根据整个系统资源情况，自动指定的。用户可通过CLI程序taos，在TDengine的console里，执行如下命令：
```
SHOW MNODES;
```
来查看mnode列表，该列表将列出mnode所处的dnode的End Point和角色(master, slave, unsynced 或offline)。
当集群中第一个节点启动时，该节点一定会运行一个mnode实例，否则该dnode无法正常工作，因为一个系统是必须有至少一个mnode的。如果numOfMnodes配置为2，启动第二个dnode时，该dnode也将运行一个mnode实例。
为保证mnode服务的高可用性，numOfMnodes必须设置为2或更大。因为mnode保存的元数据必须是强一致的，如果numOfMnodes大于2，复制参数quorum自动设为2，也就是说，至少要保证有两个副本写入数据成功，才通知客户端应用写入成功。
##负载均衡
有三种情况，将触发负载均衡，而且都无需人工干预。
- 当一个新节点添加进集群时，系统将自动触发负载均衡，一些节点上的数据将被自动转移到新节点上，无需任何人工干预。
- 当一个节点从集群中移除时，系统将自动把该节点上的数据转移到其他节点，无需任何人工干预。
- 如果一个节点过热（数据量过大），系统将自动进行负载均衡，将该节点的一些vnode自动挪到其他节点。
当上述三种情况发生时，系统将启动一各个节点的负载计算，从而决定如何挪动。
##节点离线处理
如果一个节点离线，TDengine集群将自动检测到。有如下两种情况：
- 改节点离线超过一定时间（taos.cfg里配置参数offlineThreshold控制时长)，系统将自动把该节点删除，产生系统报警信息，触发负载均衡流程。如果该被删除的节点重现上线时，它将无法加入集群，需要系统管理员重新将其添加进集群才会开始工作。
- 离线后，在offlineThreshold的时长内重新上线，系统将自动启动数据恢复流程，等数据完全恢复后，该节点将开始正常工作。
##Arbitrator的使用
如果副本数为偶数，当一个vnode group里一半vnode不工作时，是无法从中选出master的。同理，一半mnode不工作时，是无法选出mnode的master的，因为存在“split brain”问题。为解决这个问题，TDengine引入了arbitrator的概念。Arbitrator模拟一个vnode或mnode在工作，但只简单的负责网络连接，不处理任何数据插入或访问。只要包含arbitrator在内，超过半数的vnode或mnode工作，那么该vnode group或mnode组就可以正常的提供数据插入或查询服务。比如对于副本数为2的情形，如果一个节点A离线，但另外一个节点B正常，而且能连接到arbitrator, 那么节点B就能正常工作。
TDengine安装包里带有一个执行程序tarbitrator, 找任何一台Linux服务器运行它即可。该程序对系统资源几乎没有要求，只需要保证有网络连接即可。该应用的命令行参数`-p`可以指定其对外服务的端口号，缺省是6030。配置每个taosd实例时，可以在配置文件taos.cfg里将参数arbitrator设置为Arbitrator的End Point。如果该参数配置了，当副本数为偶数时，系统将自动连接配置的Arbitrator。
在配置了Arbitrator的情况下，它也会显示在“show dnodes;”指令给出的节点列表中。

# Java Connector # Java Connector
Java连接器支持的系统有： TDengine 提供了遵循 JDBC 标准（3.0）API 规范的 `taos-jdbcdriver` 实现，可在 maven 的中央仓库 [Sonatype Repository][1] 搜索下载。

Java连接器的使用请参见<a href=https://www.taosdata.com/blog/2020/11/11/1955.html>视频教程</a>。 `taos-jdbcdriver` 的实现包括 2 种形式： JDBC-JNI 和 JDBC-RESTful（taos-jdbcdriver-2.0.17 开始支持 JDBC-RESTful）。 JDBC-JNI 通过调用客户端 libtaos.so（或 taos.dll ）的本地方法实现， JDBC-RESTful 则在内部封装了 RESTful 接口实现。
TDengine 为了方便 Java 应用使用，提供了遵循 JDBC 标准(3.0)API 规范的 `taos-jdbcdriver` 实现。目前可以通过 [Sonatype Repository][1] 搜索并下载。 ![tdengine-connector](../assets/tdengine-jdbc-connector.png)
由于 TDengine 是使用 c 语言开发的，使用 taos-jdbcdriver 驱动包时需要依赖系统对应的本地函数库。 上图显示了 3 种 Java 应用使用连接器访问 TDengine 的方式：
* libtaos.so * JDBC-JNI：Java 应用在物理节点1（pnode1）上使用 JDBC-JNI 的 API ，直接调用客户端 API（libtaos.so 或 taos.dll）将写入和查询请求发送到位于物理节点2（pnode2）上的 taosd 实例。
在 linux 系统中成功安装 TDengine 后，依赖的本地函数库 libtaos.so 文件会被自动拷贝至 /usr/lib/libtaos.so，该目录包含在 Linux 自动扫描路径上，无需单独指定。 * RESTful：应用将 SQL 发送给位于物理节点2（pnode2）上的 RESTful 连接器，再调用客户端 API（libtaos.so）。
* JDBC-RESTful：Java 应用通过 JDBC-RESTful 的 API ，将 SQL 封装成一个 RESTful 请求，发送给物理节点2的 RESTful 连接器。
* taos.dll
在 windows 系统中安装完客户端之后，驱动包依赖的 taos.dll 文件会自动拷贝到系统默认搜索路径 C:/Windows/System32 下，同样无需要单独指定。
> 注意：在 windows 环境开发时需要安装 TDengine 对应的 [windows 客户端][14]，Linux 服务器安装完 TDengine 之后默认已安装 client，也可以单独安装 [Linux 客户端][15] 连接远程 TDengine Server。 TDengine 的 JDBC 驱动实现尽可能与关系型数据库驱动保持一致，但时序空间数据库与关系对象型数据库服务的对象和技术特征存在差异，导致 `taos-jdbcdriver` 与传统的 JDBC driver 也存在一定差异。在使用时需要注意以下几点：
TDengine 的 JDBC 驱动实现尽可能的与关系型数据库驱动保持一致，但时序空间数据库与关系对象型数据库服务的对象和技术特征的差异导致 taos-jdbcdriver 并未完全实现 JDBC 标准规范。在使用时需要注意以下几点： * TDengine 目前不支持针对单条数据记录的删除操作。
* 目前不支持事务操作。
* TDengine 不提供针对单条数据记录的删除和修改的操作，驱动中也没有支持相关方法。
* 由于不支持删除和修改，所以也不支持事务操作。
* 目前不支持表间的 union 操作。 * 目前不支持表间的 union 操作。
* 目前不支持嵌套查询(nested query)，对每个 Connection 的实例，至多只能有一个打开的 ResultSet 实例；如果在 ResultSet还没关闭的情况下执行了新的查询，TSDBJDBCDriver 则会自动关闭上一个 ResultSet。 * 目前不支持嵌套查询（nested query）。

## JDBC的使用说明
### 获取连接 ### 获取连接
#### 通过JdbcUrl获取连接 #### 指定URL获取连接
通过指定URL获取连接，如下所示：
```java
Class.forName("com.taosdata.jdbc.rs.RestfulDriver");
String jdbcUrl = "jdbc:TAOS-RS://taosdemo.com:6041/test?user=root&password=taosdata";
Connection conn = DriverManager.getConnection(jdbcUrl);
```
以上示例，使用 **JDBC-RESTful** 的 driver，建立了到 hostname 为 taosdemo.com，端口为 6041，数据库名为 test 的连接。这个 URL 中指定用户名（user）为 root，密码（password）为 taosdata。
使用 JDBC-RESTful 接口，不需要依赖本地函数库。与 JDBC-JNI 相比，仅需要：
1. driverClass 指定为“com.taosdata.jdbc.rs.RestfulDriver”；
2. jdbcUrl 以“jdbc:TAOS-RS://”开头；
3. 使用 6041 作为连接端口。
如果希望获得更好的写入和查询性能，Java 应用可以使用 **JDBC-JNI** 的driver，如下所示：
通过指定的jdbcUrl获取连接，如下所示：
```java ```java
Class.forName("com.taosdata.jdbc.TSDBDriver"); Class.forName("com.taosdata.jdbc.TSDBDriver");
String jdbcUrl = "jdbc:TAOS://taosdemo.com:6030/test?user=root&password=taosdata"; String jdbcUrl = "jdbc:TAOS://taosdemo.com:6030/test?user=root&password=taosdata";
Connection conn = DriverManager.getConnection(jdbcUrl); Connection conn = DriverManager.getConnection(jdbcUrl);
``` ```
以上示例，建立了到hostname为taosdemo.com，端口为6030（TDengine的默认端口），数据库名为test的连接。这个url中指定用户名（user）为root，密码（password）为taosdata。
以上示例，使用了 JDBC-JNI 的 driver，建立了到 hostname 为 taosdemo.com，端口为 6030（TDengine 的默认端口），数据库名为 test 的连接。这个 URL 中指定用户名（user）为 root，密码（password）为 taosdata。

不能。因为TDengine是为联网设备采集的数据设计的，不容许修改。但TDengine提供数据保留策略，只要数据记录超过保留时长，就会被自动删除。 TDengine 目前尚不支持删除功能，未来根据用户需求可能会支持。
从 2.0.8.0 开始，TDengine 支持更新已经写入数据的功能。使用更新功能需要在创建数据库时使用 UPDATE 1 参数，之后可以使用 INSERT INTO 命令更新已经写入的相同时间戳数据。UPDATE 参数不支持 ALTER DATABASE 命令修改。没有使用 UPDATE 1 参数创建的数据库，写入相同时间戳的数据不会修改之前的数据，也不会报错。

## 17. TDengine 是否支持删除或更新已经写入的数据？
TDengine 目前尚不支持删除功能，未来根据用户需求可能会支持。
从 2.0.8.0 开始，TDengine 支持更新已经写入数据的功能。使用更新功能需要在创建数据库时使用 UPDATE 1 参数，之后可以使用 INSERT INTO 命令更新已经写入的相同时间戳数据。UPDATE 参数不支持 ALTER DATABASE 命令修改。没有使用 UPDATE 1 参数创建的数据库，写入相同时间戳的数据不会修改之前的数据，也不会报错。
