原文出自http://www.ttlsa.com/mysql/install-mysql5_6/

1. 安装必要的组件

yum install –y autoconf automake imake libxml2-devel\

expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel

2. 下载解压mysql软件

# cd /usr/local/src

# wget -c http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz

/from/http://cdn.mysql.com/ -O mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz

# tar zxvf mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz –C ../

# cd /usr/local/

# ln -s mysql-5.6.14-linux-glibc2.5-x86_64 mysql

3. 创建Mysql用户组和用户，及数据库存放目录：

# mkdir -p /data/mysql_data_3306

# mkdir -p /data/mysql_log

# mkdir -p /data/log-bin

# groupadd mysql

# useradd mysql -g mysql -M -s /sbin/nologin

# chown -R mysql.mysql /data/mysql_data_3306 /data/mysql_log /data/log-bin

# chown -R mysql.mysql /usr/local/mysql-5.6.14-linux-glibc2.5-x86_64

4. 配置文件（依具体环境）

# vi /etc/my.cnf

[mysqld]

5. 系统服务

# cp -af /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld_3306

# vi /etc/init.d/mysqld_3306

修改两处位置：

basedir=/usr/local/mysql

datadir=/data/mysql_data_3306

执行如下命令

# chmod 755 /etc/init.d/mysqld_3306

# chkconfig --add mysqld_3306

# chkconfig --level 345 mysqld_3306 on

6. 初始化数据库

1 2	# cd /usr/local/mysql # ./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf

7. 启动数据库进程

1	# service mysqld_3306 start

8. 修改root密码

# /usr/local/mysql/bin/mysql -p -uroot -S /tmp/mysql.sock #这里直接回车就能进入数据库系统

Mysql>deletefrommysql.userwhereuser='';

Mysql>updatemysql.usersetpassword=PASSWORD(‘xxxxxxxx’)whereuser='root';

Mysql>flushprivileges;

ln -s /usr/local/mysql/bin/mysql /usr/bin
