破解Mariadb数据库root密码

先停止Mariadb服务：

systemctl stop mariadb

找并运行 mysqld_safe 程序绕开 MariaDB5.5 数据库密码验证

[root@localhost ~]# find / -name mysqld_safe
/usr/bin/mysqld_safe
[root@localhost ~]# /usr/bin/mysqld_safe --skip-grant-tables &

我们再打开一个ssh终端，直接使用 mysql 命令登录 MariaDB5.5 数据库并修改 root 登录密码

[root@localhost ~]# mysql
