八、找回丢失的mysql root用户密码
1、启动修改丢失的MySQL单实例root密码方法
1)首先停止mysql
[root@localhost ~]# /etc/init.d/mysqld stop
Shutting down MySQL. SUCCESS!
2)使用--skip-grant-tables启动mysql,忽略授权登录验证
[root@localhost ~]# mysqld_safe --skip-grant-tables --user=mysql & [1] 1866 [root@localhost ~]# 190919 01:16:35 mysqld_safe Logging to ‘/application/mysql-5.5.32/data/localhost.localdomain.err‘. 190919 01:16:35 mysqld_safe Starting mysqld daemon with databases from /application/mysql-5.5.32/data [root@localhost ~]# mysql < == 登录时空密码
3)修改root密码为新密码
mysql> update mysql.user set password=password(‘dubin‘) where user=‘root‘ and host=‘localhost‘; Query OK, 1 row affected (0.13 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> quit Bye
4)重启服务器再登录
[root@localhost ~]# /etc/init.d/mysqld stop Shutting down MySQL.190919 01:20:07 mysqld_safe mysqld from pid file /application/mysql-5.5.32/data/localhost.localdomain.pid ended SUCCESS! [1]+ Done mysqld_safe --skip-grant-tables --user=mysql [root@localhost ~]# /etc/init.d/mysqld start Starting MySQL.. SUCCESS! [root@localhost ~]# mysql -uroot -pdubin Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.5.32 Source distribution ##这里应该是不能用stop停止的,可能是我用set设置密码的原因 应该是用mysqladmin停止服务
2、多实例MySQL启动修改丢失root密码
1)关闭mysql
[root@localhost ~]# kill mysqld
2)启动时加 --skip-grant-tables参数
3)修改密码的方法
4)重启服务用新密码登录
