背景：在糾結使用Jenkins還是GitLab作爲CI/CD工具，最終決定使用GitLab，原因就是非常看好GitLab的未來。
安裝環境：
- CentOS 7.8.2003
部署：
>>> sudo yum install -y curl policycoreutils-python openssh-server
>>> sudo systemctl enable sshd
>>> sudo systemctl start sshd
# 由於之前安裝Harbor已經將防火牆關閉，故以下命令可不執行
>>> sudo firewall-cmd --permanent --add-service=http
>>> sudo firewall-cmd --permanent --add-service=https
>>> sudo systemctl reload firewalld
>>> sudo yum install postfix
>>> sudo systemctl enable postfix
>>> sudo systemctl start postfix
這裏安裝的是ee版而非ce版，關於ee和ce的區別參考：https://about.gitlab.com/install/ce-or-ee/
簡單來說就是ce版有的ee版都有，ee版有的ce版不一定有，ce版更改爲ee版需暫時終止服務

Upgrade complete! If your GitLab server is misbehaving try running
sudo gitlab-ctl restart
before anything else.
If you need to roll back to the previous version you can use the database
backup made during the upgrade (scroll up for the filename).

- 由於該主機80端口已被佔用，故將nginx監聽端口改爲9091，將unicorn端口由常用的8080端口改爲9092
- 由於我的gitlab只存在於內網環境，故暫時不考慮https
# 修改配置
>>> vi /etc/gitlab/gitlab.rb
external_url 'http://xx.xx.xx.xx:9091'
nginx['listen_port'] = 9091
unicorn['port'] = 9092
# 使配置生效

使用
打開 http://xx.xx.xx.xx:9091
默認管理賬戶爲root
在github中創建accesstoken https://github.com/settings/tokens
如果只選擇read:packages則只能看到公開的項目，勾選repo則能夠看到私有的項目
由於網絡原因導入過程比較慢，耐心等待就好
如果出現下圖，是因爲訪問github超時，多刷新幾次就好了

由於網絡原因，使用從github導入會非常非常慢，這裏推薦使用從url導入，僅需幾秒鐘就搞定

上面介紹瞭如何從github將項目遷移至gitlab，但如果項目想要同時push到gitlab和github該怎麼做呢？
我們在github和gitlab同時創建空的名爲test的私有項目，然後從gitlab clone下該項目：
>>> git clone http://xx.xx.xx.xx:9091/name/test.git
Cloning into 'test'...
Username for 'http://xx.xx.xx.xx:9091': name
Password for 'http://[email protected]:9091':
warning: You appear to have cloned an empty repository.
添加文件並提交
>>> touch test
>>> git add .
>>> git commit -m 'added test'
關鍵步驟來了，如果想同時push給gitlab和github，則直接編輯.git/config文件
>>> vim .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = http://xx.xx.xx.xx:9091/name/test.git
url = https://github.com/name/test.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
push
>>> git push origin master
Username for 'http://xx.xx.xx..xx:9091': name
Password for 'http://[email protected]:9091':

* [new branch] master -> master

! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/name/test.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
發現push到github時出現了拒絕，原因是這個項目本來是在gitlab上的，中間添加github，github會拒絕接受push，這時只需添加-f參數，強制push，但這會完全覆蓋github項目原來的文件
>>> git push -f origin master
Username for 'http://xx.xx.xx.xx:9091': name
Password for 'http://[email protected]:9091':
