1）下载：
在mysql的网站上，下载 mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz
比如拷贝到 /soft/mysql5/ 目录下。
2）解压：
[root@server local]#cd /usr/local
[root@server local]#tar zxvf /soft/mysql5/mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz
3）建立软链接：
[root@server local]#ln -s mysql-5.6.13-linux-glibc2.5-x86_64 mysql
查看：
[root@server local]# ls -lrt mysql
lrwxrwxrwx 1 root root 36 9月 12 13:22 mysql -> ./mysql-5.6.13-linux-glibc2.5-x86_64
[root@server local]#
4）建立mysql相关的用户和组：
[root@server local]#groupadd mysql
[root@server local]#useradd -r -g mysql mysql
5）生成数据库：
[root@server local]# cd mysql
[root@server local]# chown -R mysql .
[root@server local]#chgrp -R mysql .
[root@server local]# scripts/mysql_install_db --user=mysql
[root@server local]# chown -R root .
[root@server local]# chown -R mysql data
6）拷贝必要的文件(此为可选步骤)：
[root@server local]#cp support-files/mysql.server /etc/init.d/mysql.server
7）启动数据库：
[root@server local]bin/mysqld_safe --user=mysql &
8）访问数据库：
[root@server ~]# mysql --user=mysql

[root@server ~]#
9）关闭数据库时，发现无法关闭数据库，于是强制关闭进程，然后退出。
10）设置权限：
重新启动数据库（带 --skip-grant-tables参数）：
[root@server ~]# mysqld_safe --skip-grant-tables &
[1] 3140
[root@server ~]# 130912 14:49:51 mysqld_safe Logging to '/usr/local/mysql/data/server.gao.err'.
130912 14:49:51 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
设置root用户的口令（被要求Enter password的时候，直接按回车键就过去了）：
[root@server ~]# mysql -uroot -p
Enter password:

[root@server ~]#
为了验证是否可以正常关闭，再次重新启动来看一下：
[root@server ~]# mysqld_safe --skip-grant-tables
130912 14:57:36 mysqld_safe Logging to '/usr/local/mysql/data/server.gao.err'.
130912 14:57:36 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
[root@server ~]#
然后运行：
[root@server ~]# mysqladmin -uroot shutdown
[root@server ~]#
成功关闭。
下一次，完全正常启动，看能否关闭：
[root@server ~]# mysqld_safe
130912 15:01:26 mysqld_safe Logging to '/usr/local/mysql/data/server.gao.err'.
130912 15:01:26 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
[root@server ~]# mysqladmin -uroot -p shutdown
Enter password:
[root@server ~]#
关闭成功了。
