1，下载mysql安装包 http://dev.mysql.com/downloads/，这个网站有好多版本，根据自己的需要下载。
2，安装mysql所需的必要组件，
[root@localhost php-5.5.28]# yum install –y autoconf automake imake libxml2-devel\
> expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel
3，解压
[root@localhost ~]# tar zxvf /tmp/install/mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz -C /usr/local/mysql
4，创建用户并赋给与权限。
[root@localhost ~]# useradd -s /sbin/nologin mysql
[root@localhost ~]# chown -R mysql.mysql .
5，初始化数据库
[root@localhost ~]# mkdir -p /data/mysql; chown -R mysql:mysql /data/mysql
[root@localhost ~]# ./scripts/mysql_install_db --user=mysql --datadir=/mydata/data
[root@localhost ~]# cd /usr/local/mysql
6，拷贝配置文件
[root@localhost mysql]#cp support-files/my-large.cnf /etc/my.cnf
7,拷贝mysql启动脚本文件并修改相关的配置文件，找到datadir=/data/mysql添加并启动配置文件。
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# chmod +x /etc/init.d/mysqld
root@localhost mysql]#vi /etc/init.d/mysqld
[root@localhost ~]#chkconfig -add mysqld
[root@localhost ~]#chkconfig mysqld on
[root@localhost ~]#service mysqld start
修改datadir=/data/mysql否则会有报错。
8，如果有报错的话，可以查看该文件/data/mysql/localhost.localdomain.err逐层拍错。
9，启动mysql数据库
[root@localhost mysql]# service mysqld start
Starting MySQL. SUCCESS!
10，给mysql添加环境变量（注意重启后会失效）
[root@localhost mysql]# PATH=$PATH:/usr/local/mysql/bin
11,把环境变量添加到开机启动项（重启后环境变量继续有效）：
[root@localhost mysql]# echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
[root@localhost mysql]# source /etc/profile
12，进入mysql数据库使用
[root@localhost ~]# /usr/local/mysql/bin/mysql -uroot
出的话，直接输入quit或者exit即可，如果永久生效的话，并使开机生效
[root@localhost mysql]# mysql -uroot -p
