安装成功后启动mysql服务
[root@www software]# systemctl start mysql.service
运行/usr/bin/mysql_secure_installation
[root@www software]# /usr/bin/mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. You already have a root password set, so you can safely answer 'n'. Change the root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success! By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL! Cleaning up...
按照如上图的步骤选择自己需要移除和修改的配置，至此mysql安装成功
mysql的简单配置
[root@localhost software]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 12 Server version: 5.6.25 MySQL Community Server (GPL)
由于默认的root账号是只能本机登录，新增远程连接账号，为了方便，我这里新增的是远程管理员账号
mysql> create user 'admin'@'%' identified by 'admin'; Query OK, 0 rows affected (0.00 sec) mysql> grant all privileges on *.* to 'admin'@'%'; Query OK, 0 rows affected (0.00 sec)
这里mysql的安装和简单配置都完成
