本文记录CentOS7安装Firefly的过程及遇到的错误
安装也可以同时参考社区提供的文章：
http://www.9miao.com/forum.php?mod=viewthread&tid=33009&fromuid=87
没有安装mysql的请先参考这篇文章，快速安装：
http://blog.csdn.net/alex_my/article/details/44711139
1 安装第三方库：
easy_install twisted
easy_install python-memcached
easy_install DBUtils
easy_install zope.interface
easy_install affinity
easy_install MySQL-python
2 遇到的问题
-1： twisted
问题:twisted/runner/portmap.c:10:20: fatal error: Python.h: No such file or directory
解决方法：安装python-dev
yum -y install python-devel.x86_64
-2: MySQL-python
问题：mysql_config not found
原因：mysql_config位置不对，而我是就没有安装mysql，安装好后没有遇到该问题。
解决方法：来自社区参考文章
方法1:
sudo ln -s /usr/local/mysql/bin/mysql_config /usr/local/bin/mysql_config
将mysql_confi从你的安装目录链接到/usr/local/bin目录下，这样就可以在任意目录下访问了（也可以放到/usr/bin）
方法2：
编辑源码文件夹的site.cfg文件，去掉#mysql_config = /usr/local/bin/mysql_config前的注释＃，修改后面的路径为你的mysql_config真正的目录就可以了。（如果不知道 mysql_config在哪里，运行命令：whereis mysql_config）
3 检测是否正常安装
-1：创建一个新的工程
firefly-admin.py createproject Test
cd Test
-2: 修改config.json配置
--1：普通用户无法使用1000端口号，所以，netport使用的1000请修改为其它值，比如10000
--2：db-passwd请修改为自己所使用的mysql密码，比如123456
-3：运行
python startmaster.py

-4: 修复警告
过程中出现一个大意是说~/.python-eggs不安全
解决方案：
chmod g-w ~/.python-eggs/ # 将group的写权限去除
chmod o-w ~/.python-eggs/ # 将other的写权限去除
-5: 一个更具体的示例：多人聊天室
