感谢官方文档！这才是最好的教材

1、修改nginx配置文件，proxy_pass不进行前端访问ip进行后转   【临时解决方案】
2、修改/opt/gitlab/embedded/service/gitlab-rails/config/initializers/1_settings.rb添加白名单 【修改源码的方案】
3、在/etc/gitlab/gitlab.rb中添加白名单  【本文采取方案】

wget https://downloads-packages.s3.amazonaws.com/ubuntu-14.04/gitlab_7.9.0-omnibus.2-1_amd64.deb

参考官网安装：
https://about.gitlab.com/downloads/#ubuntu1404
http://doc.gitlab.com/ce/install/installation.html

打开/etc/gitlab/gitlab.rb,将external_url = 'http://hostname'修改为自己的IP地址：http://xxx.xx.xxx.xx,，然后执行下面的命令，对GitLab进行编译。
sudo gitlab-ctl reconfigure

the ffi-yajl and yajl-ruby gems have incompatible C libyajl libs and should not be loaded in the same Ruby VM
falling back to ffi which might work (or might not, no promises)

很多时候需要看官方文档才行，要不然会吃亏
另外就是官方文档的配置模板一定要详细查看
