注意：这个MySQL5.6.45版本有问题，修改配置文件不生效，推荐安装MySQL5.6.43

检测系统是否自带安装mysql
# yum list installed | grep mysql
删除系统自带的mysql
# yum -y remove mysql-libs.x86_64
由于这个mysql的yum源服务器在国外，所以下载速度会比较慢，mysql5.6只有79M大，而mysql5.7就有182M。
安装mysql-community-release-el7-5.noarch.rpm包
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
[root@localhost ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

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 passwordfor root (enter fornone): #回车
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] y #是否设置root密码
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 createdforthem. This is intended onlyfor testing, and to makethe installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y #是否删除匿名用户
... 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 rootlogin remotely? [Y/n] n #是否禁止root用户远程登录
... skipping.
By default, MySQL comes with a database named'test'that anyone can
access. This is also intended onlyfortesting, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y #是否删除test数据库-Dropping test database...
ERROR1008 (HY000) at line 1: Can't drop database'test'; database doesn't exist
... Failed!Not critical, keep moving...-Removing privileges on test database...
... Success!Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y #是否刷新权限配置生效
... Success!Alldone! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanksfor using MySQL!Cleaning up...
再次进入mysql会出现如下情况
