環境背景:CentOS 7.2
一、編輯/usr/lib/systemd/system/mariadb.service 檔案,在Service段中添加 |
123456789101112 |
[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、鍵入systemctl daemon-reload使其立即生效 |
1 |
[[email protected] ~] # systemctl daemon-reload |
三、重新啟動mariadb服務並使用mysql聯入 |
1234567891011 |
[[email protected] ~] # systemctl restart mariadb.service [[email protected] ~] # 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)]> |
123456 |
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、退出並關閉mariadb服務並把/usr/lib/systemd/system/mariadb.service檔案中剛剛添加的那兩行移除 |
12 |
ExecStart= /usr/bin/mysqld_safe --basedir= /usr ExecStartPost= /usr/libexec/mariadb-wait-ready $MAINPID |
六、啟動mariadb服務,並使用新設定的密碼串連 |
1234567891011 |
[[email protected] ~] # 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)]> |
