环境介绍：
CentOS6.7
gitlab：8.6.5
需求：gitlab从8.6.5升级到8.11.7
第一、gitlab8.6.5安装
参考《GitLab完整搭建(8.6.5).docx》
第二、gitlab8.6.5升级
0.升级之前. Backup备份
It's useful to make a backup just in case things go south: (With MySQL, this may require granting "LOCK TABLES" privileges to the GitLab user on the database version)
#su - git $cd /home/git/gitlab $bundle exec rake gitlab:backup:create RAILS_ENV=production
备份的文件在/home/git/gitlab/tmp/backups目录下：
1. 停止服务
#service gitlab stop
2.获取最新版本分支代码
In the commands below, replace LATEST_TAG with the latest GitLab tag you want to update to, for example v8.0.3. Use git tag -l 'v*.[0-9]' --sort='v:refname' to see a list of all tags. Make sure to update patch versions only (check your current version with cat VERSION).
$su - git $cd /home/git/gitlab $git fetch --all $git checkout -- Gemfile.lock db/schema.rb $git checkout v8.11.7 -b v8.11.7
如果报错，删除修改过的文件
$vi VERSION
将8.6.5替换为8.11.7
3.升级gitlab-shell版本
$cd /home/git/gitlab-shell $git fetch $git checkout v`cat /home/git/gitlab/GITLAB_SHELL_VERSION` -b v`cat /home/git/gitlab/GITLAB_SHELL_VERSION`
4.升级gitlab-workhorse版本
$cd /home/git/gitlab-workhorse $git fetch $git checkout v`cat /home/git/gitlab/GITLAB_WORKHORSE_VERSION` -b v`cat /home/git/gitlab/GITLAB_WORKHORSE_VERSION` $make
5.安装库环境
$cd /home/git/gitlab
# PostgreSQL(如果数据为psql用这条命令)
$bundle install --without development test mysql --deployment
# MySQL(如果数据为mysql用这条命令)
$bundle install --without development test postgres --deployment
# Optional: clean up old gems
$bundle clean
# Run database migrations
$bundle exec rake db:migrate RAILS_ENV=production
# Clean up assets and cache
$bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
6.启动gitlab相关服务
#service gitlab start #service nginx restart
7.检查程序状态
检查GitLab及其环境是否配置正确：
$bundle exec rake gitlab:env:info RAILS_ENV=production
确保没有报错,运行一次更彻底的检查:
$bundle exec rake gitlab:check RAILS_ENV=production
如果所有项目是绿色的,那么恭喜你升级完成!
gitlab从8.6.5升级到8.11.7到此结束。
