本文详细介绍在CentOS 6.4下安装MySQL 5.6.22的过程，供需要的朋友学习参考。
一、下载MySQL 安装包
1） 打开网址： Select Platform: 选择 Linux-Generic
选择选择 Linux - Generic (glibc 2.5) (x86, 64-bit), RPM 进行下载；
linux 下下载： wget
2）下载完后解压缩并放到安装文件夹下：
tar -xf MySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle.tar
mv MySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle /usr/local/software/
mv MySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle mysql
其中里面要使用的是这两个：
MySQL数据库： MySQL-server-5.6.22-1.linux_glibc2.5.x86_64.rpm
MySQL客户端：MySQL-client-5.6.22-1.linux_glibc2.5.x86_64.rpm
3）安装环境：cat /etc/RedHat-release
CentOS release 6.4 (Final)
二、MySql安装
1）3）检查安装
在安装MySQL之前，先检查CentOS系统中是否已经安装了一个MySQL，如果已经安装先卸载，不然会导致安装新的MySQL失败。
rpm -qa | grep mysql --查看系统之前是否已安装MySQL。
mysql-libs-5.1.47-4.el6.i686 显示结果说明 CentOS6.0系统自带了一个MySQL，我们需要删除这个老版本，用root用户执行下面语句
su -
密码：
rpm -e --nodeps mysql-libs-5.1.47-4.el6.i686
先切换到"root"用户下，然后执行删除语句，删除之后，我们再次查看，发现已经成功删除了CentOS6.0自带的旧MySQL版本。
在删除MySQL的rpm后，还要进行一些扫尾操作，网上有两种操作。（备注：我在这里两种都没有用到，发现系统中并没有其他残余的MySQL信息。）
第一种善后处理：使用下面命令进行处理。
rm -rf /var/lib/mysql*
rm -rf /usr/share/mysql*
另一种善后处理：卸载后 /var/lib/mysql 中的 /etc/my.cnf 会重命名为 my.cnf.rpmsave，/var/log/mysqld.log 会重命名为 /var/log/mysqld.log.rpmsave，如果确定没用后就手工删除。
2）安装MySql 服务端
rpm -ivh MySQL-server-5.6.22-1.linux_glibc2.5.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.
Please report any problems at
The latest information about MySQL is available on the web at

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
3）检测 MySQL 3306 端口是否安打开。测试是否成功可运行 netstat 看 MySQL 端口是否打开，如打开表示服务已经启动，安装成功。MySQL 默认的端口是3306。
