我下載的阿里雲的服務器系統centos7.2是純內核版本，並沒有其他的工具，所以這個系統是非常干凈的。所以我就需要給系統安裝一一些工具，來方便系統的管理與操作，我們上面講到了關於服務器的yum的配置在這里我們會為大家講解如何使用yum 安裝我們的mysql。
在內核版本中默認自帶一個marialdb,我們用yum安裝j就會發現找不到這個mysql.所以我們需要使用另外一種方式安裝mysql.在linux中我們的軟件包是使用rpm 命令來安裝的。我們得先找到這個mysql的rpm包。我們就去mysql的社區看看。我們使用更新的方式去更新我們的mysql.
centos自帶的repo是不會自動更新每個軟件的最新版本，所以無法通過yum方式安裝MySQL的高級版本。所以，即使我使勁用yum -y install mysql mysql-server mysql-devel，也是沒有人會鳥我的。
所以，正確的安裝mysql5姿勢是要先安裝帶有可用的mysql5系列社區版資源的rpm包
[root@iZ28gvqe4biZ ~]# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
獲取http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

1:mysql-community-release-el7-5 ################################# [100%]
這個時候查看當前可用的mysql安裝資源：
[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
一般來說，只要安裝mysql-server跟mysql-client
這個時候我們可以直接使用yum的方式安裝MySQL了
[root@iZ28gvqe4biZ ~]# yum -y install mysql-community-server

重置密碼

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 [設置root用戶密碼]
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 [刪除匿名用戶]
... 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遠程登錄]
... 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 [刪除test數據庫]
- 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 [刷新權限]
... Success!
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
