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 |
[root@node1 ~]# systemctl daemon-reload
| 三、重新启动mariadb服务并使用mysql联入 |
[root@node1 ~]# systemctl restart mariadb.service [root@node1 ~]# mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 2 Server version: 5.5.44-MariaDB MariaDB Server Copyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]>
| 四、更改root用户的密码 |
MariaDB [(none)]> UPDATE mysql.user SET Password=PASSWORD(‘xiaoshui‘) WHERE user=‘root‘ and host=‘localhost‘; Query OK, 0 rows affected (0.00 sec) Rows matched: 1 Changed: 0 Warnings: 0 MariaDB [(none)]> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)
| 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 |
[root@node1 ~]# mysql -u root -h localhost -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 4 Server version: 5.5.44-MariaDB MariaDB Server Copyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]>
