GitLab安装及使用

GitLab是一个利用 Ruby on Rails 开发的开源应用程序，实现一个自托管的Git项目仓库，可通过Web界面进行访问公开的或者私人项目。

　　GitLab拥有与Github类似的功能，能够浏览源代码，管理缺陷和注释。可以管理团队对仓库的访问，它非常易于浏览提交过的版本并提供一个文件历史库。它还提供一个代码片段收集功能可以轻松实现代码复用，便于日后有需要的时候进行查找。

1. GitLab安装与配置

1.1. 基础环境准备

 [root@mini04 ~]# yum install -y curl policycoreutils openssh-server openssh-clients postfix
 ………………
 [root@mini04 ~]# systemctl start postfix

1.2. 配置yum源

　　注：由于网络问题，国内用户，建议使用清华大学的镜像源进行安装：

 [root@mini04 ~]# vim /etc/yum.repos.d/gitlab-ce.repo
 [gitlab-ce]
 name=gitlab-ce
 baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/
 repo_gpgcheck=
 gpgcheck=
 enabled=
 gpgkey=https://packages.gitlab.com/gpg.key

1.3. 更新本地yum缓存

 [root@mini04 ~]# yum makecache
 ………………

1.4. 安装GitLab

 [root@mini04 ~]# yum install -y gitlab-ce
 ………………

1.5. 配置修改

 [root@mini04 ~]# vim /etc/gitlab/gitlab.rb
 ………………
 ## GitLab URL
 ##! URL on which GitLab will be reachable.
 ##! For more details on configuring external_url see:
 ##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab
 # external_url 'http://gitlab.example.com'
 # 能够解析
 external_url 'http://mini04'

1.6. 配置并启动gitlab-ce

 [root@mini04 ~]# gitlab-ctl reconfigure
 ………………

1.7. 查看gitlab状态

 [root@mini04 ~]# gitlab-ctl status
 run: alertmanager: (pid ) 27s; run: log: (pid ) 25s
 run: gitaly: (pid ) 28s; run: log: (pid ) 28s
 run: gitlab-monitor: (pid ) 28s; run: log: (pid ) 27s
 run: gitlab-workhorse: (pid ) 28s; run: log: (pid ) 27s
 run: logrotate: (pid ) 90s; run: log: (pid ) 27s
 run: nginx: (pid ) 96s; run: log: (pid ) 27s
 run: node-exporter: (pid ) 78s; run: log: (pid ) 28s
 run: postgres-exporter: (pid ) 26s; run: log: (pid ) 25s
 run: postgresql: (pid ) 140s; run: log: (pid ) 29s
 run: prometheus: (pid ) 27s; run: log: (pid ) 27s
 run: redis: (pid ) 146s; run: log: (pid ) 28s
 run: redis-exporter: (pid ) 66s; run: log: (pid ) 27s
 run: sidekiq: (pid ) 103s; run: log: (pid ) 29s
 run: unicorn: (pid ) 110s; run: log: (pid ) 30s

1.8. GitLab常用命令

 gitlab-ctl start    # 启动所有 gitlab 组件；
 gitlab-ctl stop        # 停止所有 gitlab 组件；
 gitlab-ctl restart        # 重启所有 gitlab 组件；
 gitlab-ctl status        # 查看服务状态；
 gitlab-ctl reconfigure        # 启动服务；
 vim /etc/gitlab/gitlab.rb        # 修改默认的配置文件；
 gitlab-ctl tail        # 查看日志；
 gitlab-rake gitlab:check SANITIZE=true --trace    # 检查gitlab；

2. GitLab使用

2.1. 首次登陆

 http://10.0.0.14

首次登陆会要求修改root用户的密码。

之后对到登陆页面，使用root用户登录即可。

2.2. 添加SSH Key信息

 [root@mini04 ~]# ssh-keygen -t rsa
 Generating public/private rsa key pair.
 Enter file in which to save the key (/root/.ssh/id_rsa):
 Created directory '/root/.ssh'.
 Enter passphrase (empty for no passphrase):
 Enter same passphrase again:
 Your identification has been saved in /root/.ssh/id_rsa.
 Your public key has been saved in /root/.ssh/id_rsa.pub.
 The key fingerprint is:
 SHA256:ACvHut11cMKDaL1QzsrL3x23OyUl9cd7+kLfFW30cLM root@mini04
 The key's randomart image is:
 +---[RSA ]----+
