gitlabhq 部署小记

冬天来了，不知github是不是也去冬眠了，速度慢的像在爬，没办法，屌丝买不起vps，只能自己内网部一套开源的。

gitlabhq是github的一个开源版本，虽然不是官方的，但是已经做的有模有样，总之能想到的功能都已具备，放在国内随便改改UI就能上线建站的那种。安装文档那是写的相当滴详细，体现了码农罕有的耐性，查看文档请移步gitlab文档

以前部署中在ssh上碰到一些问题，这次在@mk-qi童鞋的点拨下，进展是相当滴顺利，下面记录一些部署过程中的问题和解决方法。

自动部署脚本如下，基本由文档转成，可以省掉很多事情(但是遇到问题要学会google哦)，假如使用的是ubuntu，官方以前也提供了一个一键安装脚本，后来不知怎么又去掉了，估计是计划赶不上变化吧

gitlabhq自动化部署脚本

sudo -u gitlab -H git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin

if [[ $? != 0 ]];then
    echo "error: gitolite is not installed correct, or the ssh key is not right"
    exit 1

gitlabhq3.0后改用unicorn(紧跟github步伐)作为默认的启动server,要将它与nginx或apache一起使用请参考archwiki的gitlab手册,下面是apache中的vhost配置(需要预先编译proxy模块)

apache vhost配置

<VirtualHost *:80>
  ServerName gitlab.myserver.com
  ServerAlias www.gitlab.myserver.com
  DocumentRoot /home/gitlab/gitlab/public
  ErrorLog /var/log/httpd/gitlab_error_log
  CustomLog /var/log/httpd/gitlab_access_log combined

  <Proxy balancer://unicornservers>
      BalancerMember http://127.0.0.1:8080
  </Proxy>

  <Directory /home/gitlab/gitlab/public>
    AllowOverride All
    Options -MultiViews
  </Directory>

  RewriteEngine on
  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
  RewriteRule ^/(.*)$ balancer://unicornservers%{REQUEST_URI} [P,QSA,L]

  ProxyPass /uploads !
  ProxyPass / balancer://unicornservers/
  ProxyPassReverse / balancer://unicornservers/
  ProxyPreserveHost on

   <Proxy *>
      Order deny,allow
      Allow from all
   </Proxy>
</VirtualHost>

unicorn的配置文件在config/unicorn.rb，修改其中的 listen="127.0.0.1:8080"，然后重启apache，通过 service gitlab start 重启unicorn，访问一下gitlab.myserver.com吧，看到登录页面就说明大功告成啦。

Q&A

### Q: 在装完gitolite后尝试git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin遇到’remote hang-up unexpected’(貌似是这么写，意会。。。) A: 我在centos6.2上遇到过这个问题，其他发行版上不知道有没有这个问题，修改

sudo chmod 400 /home/git/.ssh/authorized_keys

可以修复这个问题。貌似是centos的安全策略造成ssh私钥不生效
