環境配置
| CentOS Version | 7.6 |
| Gitlab Version | gitlab-ce-13.12.15-ce.0.el7.x86_64 |
下載rpm包
Gitlab歷史版本下載地址：https://packages.gitlab.com/gitlab/gitlab-ce（我在這裡下載的 gitlab-ce-13.12.15-ce.0.el7.x86_64.rpm 建議使用下載工具進行下載）
wget https://d20rj4el6vkp4c.cloudfront.net/7/8/el/7/package_files/76487.rpm?t=1718811948_59a1b0efcb67106db99181bc8e4ceecdd9b6f3d9
清華大學的映象站更新比較慢，有的老版本（如13版本）都沒有更新到13版本的最新版本
安裝依賴
yum -y install policycoreutils openssh-server openssh-clients postfix policycoreutils-python
開始rpm安裝gitlab-ce-13.12.15-ce.0.el7.x86_64.rpm檔案
rpm -ivh gitlab-ce-13.12.15-ce.0.el7.x86_64.rpm
安裝完成關注以下輸出，表示已經安裝成功
修改gitlab配置檔案資訊，指定服務ip和埠號
view /etc/gitlab/gitlab.rb
修改內容如下：
將external_url後面的url替換為自己的ip+埠號，（檢視埠是否被佔用，防火牆是否放開）
新增配置資訊
第一次配置資訊，需要一定的時間，請耐心等待，直到最後看到gitlab Reconfigured! 表示配置完成。
[root@localhost ~]# gitlab-ctl reconfigure ..... ..... ..... Running handlers: Running handlers complete Chef Client finished, 426/609 resources updated in 02 minutes 55 seconds gitlab Reconfigured!
注：如果發現ip或者埠等配置資訊需要更改，每次更改完之後，一定要重新載入配置 gitlab-ctl reconfigure
重啟gitlab服務
看到如下的資訊，“ok,run ”表示各個模組啟動成功。gitlab-ctl start | stop | restart
[root@localhost ~]# gitlab-ctl restart ok: run: alertmanager: (pid 224124) 0s ok: run: gitaly: (pid 224146) 0s ok: run: gitlab-monitor: (pid 224167) 1s ok: run: gitlab-workhorse: (pid 224192) 0s ok: run: logrotate: (pid 224211) 1s ok: run: nginx: (pid 224218) 0s ok: run: node-exporter: (pid 224294) 1s ok: run: postgres-exporter: (pid 224307) 0s ok: run: postgresql: (pid 224318) 0s ok: run: prometheus: (pid 224327) 0s ok: run: redis: (pid 224371) 0s ok: run: redis-exporter: (pid 224376) 1s ok: run: sidekiq: (pid 224393) 0s ok: run: unicorn: (pid 224409) 0s
到這裡已經完成了對gitlab的安裝
瀏覽器登陸
瀏覽器訪問，http://ip:埠號
第一次訪問，直接進入更改root賬號密碼的頁面，只需要填寫密碼即可，修改完，直接跳入到登陸頁面
進入到gitlab頁面後，即可開始建立自己專案（完成）

第1個報錯是：/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket: connect: connection refused
第2個報錯是：Errno::EADDRINUSE: Address already in use - bind(2) for "127.0.0.1" port 8080
在我的環境只解決埠被佔用的問題就可以了，把上面“修改gitlab配置檔案資訊，指定服務ip和埠號”，調整為8082就可以了（重新gitlab-ctl reconfigure/gitlab-ct restart即可）
補充：報8080埠被佔用，檢視8080埠發現是puma在監聽8080埠；經過上訴辦法調整成8082後重啟，發現監聽8082埠的是nginx，8080看來是puma的埠所以衝突了
