一.备份
1.使用Omnibus安装包安装
--gitlab-rake gitlab:backup:create
2.使用源码安装
--./use_gitlab----如果备份失败，PATH路径错误，执行自带的环境变量设置脚本：use_gitlab
--bundle exec rake gitlab?create RAILS_ENV=production

备份文件会产生在config/gitlab.yml所指定的目录，如果未做指定默认存储在 /home/git/gitlab/tmp/backup下面
文件名格式[TIMESTAMP]_gitlab_backup.tar

二.恢复
1.安装包恢复方法：
将产生的文件传输到相同目录
--cp 1393513186_gitlab_backup.tar /var/opt/gitlab/backups/
--gitlab-ctl stop unicorn
--gitlab-ctl stop sidekiq
--gitlab-rake gitlab:backup:restore BACKUP=1393513186
--gitlab-ctl start

2.源码安装恢复方法：
--bundle exec rake gitlab:backup:restore RAILS_ENV=production
小的版本号有差异也无法进行恢复

三.升级gitlab版本
A.使用Omnibus安装包安装的升级：
#1.安装升级软件包
#2.重新加载配置：
#hitlab-tl reconfigure
#3.重启服务:
#gitlab-ctl restart
#service gitlab stop

B.使用源码安装的升级：
#cd /etc/gitlab/gitlab
#git -H git fetch -all
#git -H git checkout --Gemfile.lock db/schema.rb
#git -H git checkout v8.14.3 -b v8.14.3

#cd /etc/gitlab/gitlab-shell
#git -H git fetch
#git -H git checkout v`cat /etc/gitlab/gitlab/GITLAB_SHELL_VERSION` -b v`cat /home/git/gitlab/GITLAB_SHELL_VERSION`#cd /etc/gitlab/gitlab-workhorse
#git -H git fetch #git -H git checkout `cat /etc/gitlab/gitlab/GITLAB_WORKHORSE_VERSION` -b `cat /etc/gitlab/gitlab/GITLAB_WORKHORSE_VERSION` #git -H make #安装 #cd /etc/gitlab/gitlab #git -H bundle install --without development test postgres --deployment #git -H bundel install --without development test mysql --deploymet #git -H bundle clean #git -H bundle exec rake db:migrate RAILS_ENV=production #git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production #更新configuration文件 #git diff origin/8-5-stable:config/gitlab.yml.example origin/8-6-stable:config/gitlab.yml.example #重新启动服务 #service gitlab start #service nginx restart #检查工作是否正常 #git -H bundle exec rake gitlab:env:info RAILS_ENV=production
