具体内容如下
1.1安装
首先执行下面三条命令：
# 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：
$ 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:
