前一篇文章《在 Ubuntu 12.04 上安装 GitLab6.x》 已经介绍了安装Gitlab6.2的过程，那么怎么升级他呢？
1. 备份
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
2. 停止gitlab服务
sudo service gitlab stop
3. 获取最新的发行版本
cd /home/git/gitlab
sudo -u git -H git fetch
删除原来的application.rb文件
sudo -u git rm -rf config/application.rb
检出新版本
sudo -u git -H git checkout 6-3-stable
4. 升级gitlab-shell
cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v1.8.0
5. 安装库并迁移他
以MySQL为例
cd /home/git/gitlab
sudo -u git -H bundle install --without development test postgres --deployment
迁移数据库
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
清除缓冲
sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
6. 升级配置文件
cd /home/git/gitlab
sudo -u git -H cp config/initializers/rack_attack.rb.example config/initializers/rack_attack.rb
7. 升级启动脚本
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
sudo chmod +x /etc/init.d/gitlab
8. 重启
sudo service gitlab start
sudo service nginx restart
终端执行情况：
tdtc010@tdtc010-Vostro-270:~$ cd /home/git/gitlab
tdtc010@tdtc010-Vostro-270:/home/git/gitlab$ sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
