mysql忘记登陆密码
mysql(mariadb)忘记登陆密码,提示如下
[root@localhost ~]# mysql -uroot -p Enter password: ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: YES)
2.停止mysql
[root@localhost ~]# systemctl stop mariadb
3.使用--skip-grant-tables连接mysql,此时mysql不能进行授权操作,可重置密码
[root@localhost ~]# mysqld_safe --skip-grant-tables 161103 14:52:25 mysqld_safe Logging to ‘/var/log/mariadb/mariadb.log‘. 161103 14:52:25 mysqld_safe A mysqld process already exists
4.开启mysql并直接进入
[root@localhost ~]# systemctl start mariadb [root@localhost ~]# mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 2 Server version: 5.5.50-MariaDB MariaDB Server Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help.

5.已重置密码为123456,测试登录
[root@localhost ~]# mysql -uroot -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g.
