2、进入mysql，查看root用户的详细信息

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

*************************** 1. row ***************************                   Host: localhost                   User: root            Select_priv: Y            Insert_priv: Y            Update_priv: Y            Delete_priv: Y            Create_priv: Y              Drop_priv: Y            Reload_priv: Y          Shutdown_priv: Y           Process_priv: Y              File_priv: Y             Grant_priv: Y        References_priv: Y             Index_priv: Y             Alter_priv: Y           Show_db_priv: Y             Super_priv: Y  Create_tmp_table_priv: Y       Lock_tables_priv: Y           Execute_priv: Y        Repl_slave_priv: Y       Repl_client_priv: Y       Create_view_priv: Y         Show_view_priv: Y    Create_routine_priv: Y     Alter_routine_priv: Y       Create_user_priv: Y             Event_priv: Y           Trigger_priv: Y Create_tablespace_priv: Y               ssl_type:             ssl_cipher:            x509_issuer:           x509_subject:          max_questions: 0            max_updates: 0        max_connections: 0   max_user_connections: 0                 plugin: mysql_native_password  authentication_string: *AC241830FFDDC8943AB31CBD47D758E79F7953EA       password_expired: N  password_last_changed: 2015-11-11 16:52:49      password_lifetime: NULL         account_locked: N 1 row in set (0.00 sec)

3、把password_expired 改成不过期

1 2 3

>  update user set password_expired='N' where user='root';         > flush privileges;         > quit

4、把 /etc/my.cnf 的 skip-grant-tables 这行注释掉

5、重启服务

1	#service mysql restart

6、再次登陆 mysql 就正常了
