# MySQL接口 {#mysql-interface}
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:
``` xml
<mysql_port>9004</mysql_port>
```
使用命令行工具连接的示例 `mysql`:
``` 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
限制:
- 不支持准备好的查询
- 某些数据类型以字符串形式发送
