# MySQL接口 {#mysql-interface}
|
||
|
||
ClickHouse支持MySQL wire通讯协议。可以通过在配置文件中设置 [mysql_port](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-mysql_port) 来启用它:
|
||
|
||
``` xml
|
||
<mysql_port>9004</mysql_port>
|
||
```
|
||
|
||
使用命令行工具 `mysql` 进行连接的示例:
|
||
|
||
``` bash
|
||
$ mysql --protocol tcp -u default -P 9004
|
||
```
|
||
|
||
如果连接成功，则输出:
|
||
|
||
``` text
|
||
Welcome to the MySQL monitor. Commands end with ; or \g.
|
||
Your MySQL connection id is 4
|

|
||
|
||
为了与所有MySQL客户端兼容，建议在配置文件中使用 [double SHA1](../operations/settings/settings-users.md#password_double_sha1_hex) 来指定用户密码。
|
||
如果使用 [SHA256](../operations/settings/settings-users.md#password_sha256_hex) 指定用户密码，一些客户端将无法进行身份验证（比如mysqljs和旧版本的命令行工具mysql）。
