gitlab-ce离线安装
GitLab 是一个用于仓库管理系统的开源项目，使用Git作为代码管理工具，并在此基础上搭建起来的web服务。本文基于CentOS 7.3，离线安装GitLab-CE（gitlab-ce-11.7.5-ce.0.el7.x86_64.rpm）。
1、下载离线rpm，安装
[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: 头V4 RSA/SHA1 Signature, 密钥 ID f27eab47: NOKEY

It looks like GitLab has not been configured yet; skipping the upgrade script.

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.md2、修改配置文件gitlab.rb
[root@localhost soft]# vim /etc/gitlab/gitlab.rb 将external_url 的值改为服务器ip（192.168.12.5），默认端口80，如：
external_url 'http://192.168.12.5'
3、重新配置
[root@localhost soft]#gitlab-ctl reconfigure4、启动
[root@localhost soft]#gitlab-ctl start
