title: Configuration Parameters
description: "Configuration parameters for client and server in TDengine"
---

## Configuration File on Server Side

On the server side, the actual service of TDengine is provided by an executable `taosd` whose parameters can be configured in file `taos.cfg` to meet the requirements of different use cases. The default location of `taos.cfg` is `/etc/taos`, but can be changed by using `-c` parameter on the CLI of `taosd`. For example, the configuration file can be put under `/home/user` and used like below

```
taosd -c /home/user
```

Parameter `-C` can be used on the CLI of `taosd` to show its configuration, like below:

```
taosd -C
```

## Configuration File on Client Side

TDengine CLI `taos` is the tool for users to interact with TDengine. It can share same configuration file as `taosd` or use a separate configuration file. When launching `taos`, parameter `-c` can be used to specify the location where its configuration file is. For example `taos -c /home/cfg` means `/home/cfg/taos.cfg` will be used. If `-c` is not used, the default location of the configuration file is `/etc/taos`. For more details please use `taos --help` to get.

```bash
taos -C
```

```bash
taos --dump-config
```

# Configuration Parameters

:::note
The parameters described in this document by the effect that they have on the system.

:::note
`taosd` needs to be restarted for the parameters changed in the configuration file to take effect.

## Locale Parameters

### timezone

| Attribute     | Description                                                                                                                                                                         |
| -------- | ------------------------------ |
| Applicable    | Server and Client                                                                                                      |
| Meaning       | TimeZone                        |
| Default Value | TimeZone configured in the host |

:::info
To handle the data insertion and data query from multiple timezones, Unix Timestamp is used and stored in TDengine. The timestamp generated from any timezones at same time is same in Unix timestamp. Note that Unix timestamps are converted and recorded on the client side. To make sure the time on client side can be converted to Unix timestamp correctly, the timezone must be set properly.

On Linux system, TDengine clients automatically obtain timezone from the host. Alternatively, the timezone can be configured explicitly in configuration file `taos.cfg` like below. For example:

```
timezone UTC-8
timezone GMT-8
timezone Asia/Shanghai
```

The above examples are all proper configuration for the timezone of UTC+8. On Windows system, however, `timezone Asia/Shanghai` is not supported, it must be set as `timezone UTC-8`.

The setting for timezone impacts strings that are not in Unix timestamp format and keywords or functions related to date/time. For example:

```sql
SELECT count(*) FROM table_name WHERE TS<'2019-04-11 12:01:08';
```

If the timezone is UTC+8, the above SQL statement is equal to:

```sql
SELECT count(*) FROM table_name WHERE TS<1554955268000;
```

If the timezone is UTC, it's equal to

```sql
SELECT count(*) FROM table_name WHERE TS<1554984068000;
```

To avoid the problems of using time strings, Unix timestamp can be used directly. Furthermore, time strings with timezone can be used in SQL statements. For example "2013-04-12T15:52:01.123+08:00" in RFC3339 format or "2013-04-12T15:52:01.123+0800" in ISO-8601 format are not influenced by timezone setting when converted to Unix timestamp.

### locale

| Attribute     | Description               |
| ------------- | ------------------------- |
| Applicable    | Server and Client         |
| Meaning       | Location code             |
| Default Value | Locale configured in host |

:::info
A specific type "nchar" is provided in TDengine to store non-ASCII characters such as Chinese, Japanese, and Korean. The characters to be stored in nchar type are firstly encoded in UCS4-LE before sending to server side. Note that the correct encoding is determined by the user. To store non-ASCII characters correctly, the encoding format of the client side needs to be set properly.

The characters input on the client side are encoded using the default system encoding, which is UTF-8 on Linux, or GB18030 or GBK on some systems in Chinese, POSIX in docker, CP936 on Windows in Chinese. The encoding of the operating system in use must be set correctly so that the characters in nchar type can be converted to UCS4-LE.

The locale definition standard on Linux is: <Language\>\_<Region\>.<charset\>, for example, in "zh_CN.UTF-8", "zh" means Chinese, "CN" means China mainland, "UTF-8" means charset. The charset indicates how to display the characters. On Linux and Mac OSX, the charset can be set by locale in the system. On Windows system another configuration parameter `charset` must be used to configure charset because the locale used on Windows is not POSIX standard. Of course, `charset` can also be used on Linux to specify the charset.

:::

### charset

| Attribute     | Description               |
| ------------- | ------------------------- |
| Applicable    | Server and Client         |
| Meaning       | Character                 |
| Default Value | charset set in the system |

:::info
On Linux, if `charset` is not set in `taos.cfg`, when `taos` is started, the charset is obtained from system locale. If obtaining charset from system locale fails, `taos` would fail to start.

So on Linux system, if system locale is set properly, it's not necessary to set `charset` in `taos.cfg`. For example:

```
locale zh_CN.UTF-8
```

On Windows system, it's not possible to obtain charset from system locale. If it's not set in configuration file `taos.cfg`, it would be default to CP936, same as set as below in `taos.cfg`. For example

```
charset CP936
```

Refer to the documentation for your operating system before changing the charset.

On a Linux system, if the charset contained in `locale` is not consistent with that set by `charset`, the later setting in the configuration file takes precedence.

```
locale zh_CN.UTF-8
charset GBK
```

The charset that takes effect is GBK.

```
charset GBK
locale zh_CN.UTF-8
```

The charset that takes effect is UTF-8.
