环境背景：CentOS 7.2
| 一、编辑/usr/lib/systemd/system/mariadb.service 文件，在Service段中添加 |
[Service]
Type=simple
User=mysql
Group=mysql
User=mysql
Group=mysql
ExecStartPre=/usr/libexec/mariadb-prepare-db-dir %n
# Note: we set --basedir to prevent probes that might trigger SELinux alarms,
# per bug #547485
#在Server段中的ExecStart出添加如下
ExecStart=/usr/bin/mysqld_safe --basedir=/usr --skip-grant-tables --skip-networking
二、键入systemctl daemon-reload使其立即生效
|
[[email protected] ~]# systemctl daemon-reload
| 三、重新启动mariadb服务并使用mysql联入 |
[[email protected] ~]# systemctl restart mariadb.service
[[email protected] ~]# mysql

| 五、退出并关闭mariadb服务并把/usr/lib/systemd/system/mariadb.service文件中刚刚添加的那两行移除 |
ExecStart=/usr/bin/mysqld_safe --basedir=/usr
ExecStartPost=/usr/libexec/mariadb-wait-ready $MAINPID
| 六、启动mariadb服务，并使用新设置的密码连接 |
[[email protected] ~]# mysql -u root -h localhost -p
Enter password:
