GitLab 是一個用於倉庫管理系統的開源項目，使用Git作爲代碼管理工具，並在此基礎上搭建起來的web服務。本文基於CentOS 7.3，離線安裝GitLab-CE（gitlab-ce-11.7.5-ce.0.el7.x86_64.rpm）。
1、下載離線rpm，安裝
[root@localhost soft]# rpm -ivh gitlab-ce-11.7.5-ce.0.el7.x86_64.rpm
警告：gitlab-ce-11.7.5-ce.0.el7.x86_64.rpm: 頭V4 RSA/SHA1 Signature, 密鑰 ID f27eab47: NOKEY

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
sudo gitlab-ctl reconfigure
For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
2、修改配置文件gitlab.rb
[root@localhost soft]# vim /etc/gitlab/gitlab.rb
將external_url 的值改爲服務器ip（192.168.12.5），默認端口80，如：
external_url 'http://192.168.12.5'
3、重新配置
[root@localhost soft]#gitlab-ctl reconfigure
4、啓動
[root@localhost soft]#gitlab-ctl start
