删错了user表root也连不上去了,然后我们可以理解为root密码不知道了,忘记了。使用此类方法来找回root,再对删除后的user重新创建。还好不是线上的。。。 1.修改MySQL的登录设置: # vim /etc/my.cnf 在[mysqld]的段中加上一句:skip-grant-tables 例如: [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-grant-tables 保存并且退出vi。 2.重新启动mysqld # service mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ] 3.登录并修改MySQL的root密码 # mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 to server version: 3.23.56 Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the buffer. mysql> USE mysql ; Database changed mysql> UPDATE user SET Password = password ( ‘new-password‘ ) WHERE User = ‘root‘ ; Query OK, 0 rows affected (0.00 sec) Rows matched: 2 Changed: 0 Warnings: 0 mysql> flush privileges ; Query OK, 0 rows affected (0.01 sec) mysql> quit 4.将MySQL的登录设置修改回来 # vim /etc/my.cnf 将刚才在[mysqld]的段中加上的skip-grant-tables删除 保存并且退出vim 5.重新启动mysqld # service mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]
