二、密码过期问题解决
1、问题现象
[root@linux-node2 mysql]# mysql -uroot -p Enter password: ERROR 1862 (HY000): Your password has expired. To log in you must change it using a client that supports expired passwords.
2、修改配置文件/etc/my.cnf
[root@linux-node2 mysql]# vim /etc/my.cnf #在[mysqld]下增加skip-grant-tables,跳过授权表登录 [client] port = 3306 socket = /data/mysql/mysql.sock [mysql] no-auto-rehash [mysqld] user = mysql port = 3306 socket = /data/mysql/mysql.sock datadir = /data/mysql/data log-bin = /data/mysql/mysql-bin server-id = 6 skip-grant-tables [root@linux-node2 mysql]# /etc/init.d/mysqld restart Shutting down MySQL.. SUCCESS! Starting MySQL. SUCCESS!
3、登录mysql
[root@linux-node2 mysql]# mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MySQL connection id is 4 Server version: 5.7.18-log MySQL Community Server (GPL) Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MySQL [(none)]> use mysql; Database changed MySQL [mysql]> update user set password_expired='N' where user='root'; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 MySQL [mysql]> flush privileges; Query OK, 0 rows affected (0.01 sec) MySQL [mysql]> quit; Bye
4、去掉跳过授权表登录,并重启登录
[root@linux-node2 mysql]# vim /etc/my.cnf [root@linux-node2 mysql]# /etc/init.d/mysqld restart Shutting down MySQL.. SUCCESS! Starting MySQL. SUCCESS! [root@linux-node2 mysql]# mysql -uroot -p123456 Welcome to the MariaDB monitor. Commands end with ; or \g.
