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
