1.问题

• Mac 中 Mariadb 状态查询报错。

mysql.server status

ERROR! MariaDB is not running, but PID file exists

• Mariadb 无法关闭

mysql.server stop

ERROR! MariaDB server process #xxxx is not running!

• 此时 Mariadb 并没有关闭，依然可以进入数据库

mysql

Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 10.5.9-MariaDB Homebrew

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

2.解决方案

方案一

• 通过brew services管理 MariaDB

brew services start mariadb
brew services stop mariadb

方案二

• 指定--user=参数

mysql.server status --user=[my_current_user]

sudo mysql.server stop --user=[my_current_user]

• [my_current_user]指的是当前启动 MariaDB 的用户

sudo mysql.server start

sudo mysql.server status --user=root

SUCCESS! MariaDB running (4143)

sudo mysql.server status --user=root

Shutting down MariaDB
. SUCCESS!
