用的是源码包安装的方式，装的过程中可谓是历尽千辛万苦啊，总算装好了，参考的网站
http://blog.csdn.net/suixinm/article/details/20782799 （参考到：进入安装目录，将程序二进制的所有权改为root，数据目录的说有权改为mysql用户，更新授权表）这部分，下面接着参考的是
http://www.jb51.net/article/87160.htm?pc 不过在配置/etc/my.cnf后启动时会出错：
mysql: unknown variable 'character-set-client=utf8'
然后参考http://www.2cto.com/database/201510/445106.html网站修改/etc/my.cnf配置文件
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE.

然后接着参考 http://www.jb51.net/article/87160.htm?pc
就安装成功了。
下面是我的/etc/my.cnf的配置文件，可以参考下：
