3、安装完以后配置
mysql5.7安装完成后普通用户不能进mysql,原因:root的plugin被修改成了auth_socket,用密码登陆的plugin应该是mysql_native_password,直接用root权限登录就不用密码,修改root密码和登录验证方式
$ sudo su # mysql mysql> mysql> select user, plugin from mysql.user; +------------------+-----------------------+ | user | plugin | +------------------+-----------------------+ | root | auth_socket | | mysql.session | mysql_native_password | | mysql.sys | mysql_native_password | | debian-sys-maint | mysql_native_password | +------------------+-----------------------+ 4 rows in set (0.00 sec) mysql> update mysql.user set authentication_string=PASSWORD('123456'), plugin='mysql_native_password' where user='root'; mysql> flush privileges; mysql> exit Bye # exit $ sudo /etc/init.d/mysql restart $ mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.22-0ubuntu18.04.1 (Ubuntu) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

4、配置mysql远程登录
# 修改配置文件,注释掉bind-address = 127.0.0.1 $ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf # 保存退出,然后进入mysql服务,执行授权命令: $ mysql -uroot -p mysql> grant all on *.* to root@'%' identified by '123456' with grant option; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye $ sudo /etc/init.d/mysql restart
