前言
之前搭建的版本比较旧，目前官方对先前搭建的版本已不再提供支持！ 同时也是为了了解新版本的新功能，同时为集成以及CI/CD做准备！下面是文章正文，希望能帮到您
一、GitLab是什么？
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。如今，它变得更加强大。GitLab is the most comprehensive AI-powered DevSecOps Platform.
二、安装步骤
1.环境准备
系统准备：
# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
## 软件包版本
# rpm -qa | grep gitlab
gitlab-ce-16.0.2-ce.0.el7.x86_64
这里面有ee版本和ce版本的区别
https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh
这里只研究ce（社区版）的
https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh
安装前的系统检查以及配置脚本，这种方式针对可以访问公网地址可以通过脚本链接处理一些必要依赖等：
script.rpm.sh
# vi script.rpm.sh
#!/bin/bash
unknown_os ()
{
echo "Unfortunately, your operating system distribution and version are not supported by this script."
echo
echo "You can override the OS detection by setting os= and dist= prior to running this script."
echo "You can find a list of supported OSes and distributions on our website: https://packages.gitlab.com/docs#os_distro_version"

echo "For example, to force CentOS 6: os=el dist=6 ./script.sh"

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
Help us improve the installation experience, let us know how we did with a 1 minute survey:
https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=omnibus&release=16-0
验证中 : gitlab-ce-16.0.2-ce.0.el7.x86_64 1/1
已安装:
gitlab-ce.x86_64 0:16.0.2-ce.0.el7
完毕！
3.配置启动
配置
# vi /etc/gitlab/gitlab.rb
external_url 'http://10.2.6.155' #修改为自己的服务器IP地址或者域名
启动
# 重新加载配置
gitlab-ctl reconfigure
# 执行启动
gitlab-ctl restart
登陆地址：
http://10.2.6.155
总结
GitLab环境准备是第一步。接下来主要就是基于自己工作的角色去有针对性的学习！关注企业级的应用，如集成LDAP。基于不同的用户角色针对性实验。研发人员需要关注代码提交、分支管理等的常用操作并理解其具体含义以及操作的风险等！管理员需要保障服务的正常运行，权限管理、文件备份、CI/CD、安全等操作。
