entos自带的repo是不会自动更新每个软件的最新版本，所以无法通过yum方式安装MySQL的高级版本。

所以，即使使劲用`yum -y install mysql mysql-server mysql-devel`，也是没用的。   
所以，正确的安装mysql5姿势是要先安装带有可用的mysql5系列社区版资源的rpm包

[root@iZ28gvqe4biZ ~]# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
    获取http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
    准备中...                          ################################# [100%] 正在升级/安装... 1:mysql-community-release-el7-5 ################################# [100%]

这个时候查看当前可用的mysql安装资源：

[root@iZ28gvqe4biZ ~]# yum repolist enabled | grep "mysql.*-community.*"
    mysql-connectors-community/x86_64 MySQL Connectors Community                  17
    mysql-tools-community/x86_64      MySQL Tools Community                       31
    mysql56-community/x86_64          MySQL 5.6 Community Server                 199

一般来说，只要安装mysql-server跟mysql-client   
这个时候我们可以直接使用yum的方式安装MySQL了

[root@iZ28gvqe4biZ ~]# yum -y install mysql-community-server

    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.
    
    Set root password? [Y/n] y        [设置root用户密码]
    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 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            [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 root login remotely? [Y/n] n            [禁止root远程登录]
     ... skipping.
    
    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.
    
    Remove test database and access to it? [Y/n] y       [删除test数据库]
     - Dropping test database...
    ERROR 1008 (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        [刷新权限]
     ... 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...
