我下载的阿里云的服务器系统centos7.2是纯内核版本，并没有其他的工具，所以这个系统是非常干净的。所以我就需要给系统安装一一些工具，来方便系统的管理与操作，我们上面讲到了关于服务器的yum的配置在这里我们会为大家讲解如何使用yum 安装我们的mysql。
在内核版本中默认自带一个marialdb,我们用yum安装j就会发现找不到这个mysql.所以我们需要使用另外一种方式安装mysql.在linux中我们的软件包是使用rpm 命令来安装的。我们得先找到这个mysql的rpm包。我们就去mysql的社区看看。我们使用更新的方式去更新我们的mysql.
centos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，即使我使劲用yum -y install mysql mysql-server mysql-devel，也是没有人会鸟我的。
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...
