Ubuntu 18.04 安装mysql5.7

Ubuntu18.04安装mysql5.7，供大家参考，具体内容如下

1.1安装

首先执行下面三条命令：

?

1 2 3 4 5 6 7 8

# 安装mysql服务 sudo apt-get install mysql-server # 安装客户端 sudo apt install mysql-client # 安装依赖 sudo apt install libmysqlclient-dev # 检查状态 sudo netstat -tap | grep mysql

1.2设置root密码

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：

?

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

$ 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.

1.3配置mysql远程登录

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
