mysql方案一:
1.停止mysql
service mysql stop 6mysql> flush privileges;
mysql> quit;
7[root@localhost ~]# service mysql restart
1.停止mysql
service mysql stop
2.添加一下參數到mysql配置文件‘/usr/local/mysql/my.cnf’
--skip-grant-tables
3.啟動mysql
service mysql start
4.執行一下命令進入mysql
mysql
5.更新密碼註意這是mysql5.7的方式
mysql>update mysql.user set authentication_string=password(‘123456‘) where user=‘root‘ and Host =‘localhost‘;
5.7之前的應該這樣改: update user set password=password("123") where user="root";
6.去掉配置文件添加的參數‘--skip-grant-tables’,重啟mysql,就ok了
方案二:
