安装mysql前需要查询系统中含有的有关mysql的软件。
rpm -qa | grep -i mysql //grep -i是不分大小写字符查询，只要含有mysql就显示mysql-libs-5.1.71-1.el6.i686 //它是好几个软件的依赖，其中在mini版本中postfix软件依赖mysql-libs，网络上很多建议都是直接删除，yum remove mysql-libs 或者 rpm -e --nodeps mysql-libs-5.1.71-1.el6.i686，总觉得这样做不好，查找mysql官方资料，得到安装方法是用MySQL-shared-compat将mysql-libs-5.1.71-1.el6.i686替换为同版本后在安装mysql。

Starting MySQL... SUCCESS!

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): <–使用刚才得到的root的密码 NljqL63OYlGo5cqyOK, 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 <– 是否更换root用户密码，输入y并回车，强烈建议更换
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码
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 <– 是否删除匿名用户,生产环境建议删除，所以输入y并回车
...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 <–是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止 ...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.
Remove test database and access to it? [Y/n] y <– 是否删除test数据库,输入y并回车
