启动报错：
Starting MySQL.200107 16:35:31 mysqld_safe error: log-error set to ‘/var/log/mariadb/mariadb.log’, however file don’t exists. Create writable for user ‘mysql’.
ERROR! The server quit without updating PID file (/var/lib/mysql/server7.pid).
原因：没有路径也没有权限
解决方案：

1. 创建路径：mkdir /var/log/mariadb
2. 创建文件：touch /var/log/mariadb/mariadb.log
3. 授予权限：chown -R mysql:mysql /var/log/mariadb/mariadb.log
