# MySQL Interface {#mysql-interface}
|
||
|
||
ClickHouse supports MySQL wire protocol. It can be enabled by [mysql\_port](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-mysql_port) setting in configuration file:
|
||
|
||
``` xml
|
||
<mysql_port>9004</mysql_port>
|
||
```
|
||
|
||
Example of connecting using command-line tool `mysql`:
|
||
|
||
``` bash
|
||
$ mysql --protocol tcp -u default -P 9004
|
||
```
|
||
|
||
Output if a connection succeeded:
|
||
|
||
``` text
|
||
Welcome to the MySQL monitor. Commands end with ; or \g.
|
||
Your MySQL connection id is 4
|

|
||
|
||
For compatibility with all MySQL clients, it is recommended to specify user password with [double SHA1](../operations/settings/settings-users.md#password_double_sha1_hex) in configuration file.
|
||
If user password is specified using [SHA256](../operations/settings/settings-users.md#password_sha256_hex), some clients won’t be able to authenticate (mysqljs and old versions of command-line tool mysql).
