ClickHouse支持MySQL线协议。 它可以通过启用 [mysql\_port](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-mysql_port) 在配置文件中设置:
2020-04-03 13:23:32 +00:00
``` xml
<mysql_port>9004</mysql_port>
```
使用命令行工具连接的示例 `mysql`:
2020-04-03 13:23:32 +00:00
``` bash
$ mysql --protocol tcp -u default -P 9004
```
如果连接成功,则输出:
2020-04-03 13:23:32 +00:00
``` text

为了与所有MySQL客户端兼容建议使用以下命令指定用户密码 [双SHA1](../operations/settings/settings-users.md#password_double_sha1_hex) 在配置文件中。
如果使用用户密码指定 [SHA256](../operations/settings/settings-users.md#password_sha256_hex)一些客户端将无法进行身份验证mysqljs和旧版本的命令行工具mysql
