一、下载
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm二、安装
下载到指定目录后，就可以执行以下命令：
rpm -ivh gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm执行成功后，会生成/etc/gitlab/gitlab.rb这么一个文件，修改其中监听的url和端口号:
## 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-gitlabexternal_url 'http://172.17.xx.xx:80'将其中的external_url值的ip修改成当前机器的ip，端口号取80或其他值。保存退出后，顺序执行以下命令：
[root@i ~]# gitlab-ctl reconfigure[root@i ~]# gitlab-ctl restart[root@i ~]# gitlab-ctl statusrun: gitaly: (pid 25838) 2791s; run: log: (pid 20137) 4936srun: gitlab-monitor: (pid 25847) 2790s; run: log: (pid 20346) 4910srun: gitlab-workhorse: (pid 25860) 2790s; run: log: (pid 20204) 4929srun: logrotate: (pid 25870) 2790s; run: log: (pid 20267) 4922srun: nginx: (pid 32117) 1s; run: log: (pid 20211) 4928srun: node-exporter: (pid 25914) 2789s; run: log: (pid 20329) 4916srun: postgres-exporter: (pid 25920) 2788s; run: log: (pid 20394) 4902srun: postgresql: (pid 25929) 2788s; run: log: (pid 19957) 4975srun: prometheus: (pid 25937) 2787s; run: log: (pid 20376) 4903srun: redis: (pid 25945) 2787s; run: log: (pid 19897) 4981srun: redis-exporter: (pid 25951) 2787s; run: log: (pid 20360) 4909srun: sidekiq: (pid 25961) 2784s; run: log: (pid 20119) 4942srun: unicorn: (pid 25985) 2783s; run: log: (pid 20081) 4944s此时可以看到gitlab是运行的状态，如果在浏览器地址栏输入对应的ip，是可以看到登录页面的。就此安装完成！
三、登录
登录时需要账号和密码的，但此时并不知道账号密码是多少。可以执行以下命令：
[root@i ~]# gitlab-rails console productionLoading production environment (Rails 4.2.8)irb(main):001:0> u=User.find(1)=> #<User id:1 @root>irb(main):002:0> u.password='test123456'=> "test123456"irb(main):003:0> u.saveEnqueued ActionMailer::DeliveryJob (Job ID: 1657620e-55fb-4786-a0d1-dec1fbc1421d) to Sidekiq(mailers) with arguments: "DeviseMailer", "password_change", "deliver_now", gid://gitlab/User/1=> trueirb(main):004:0> exit[root@i ~]#首先是通过find方法找到id为1的用户，也就是root，然后修改它的密码为test123456，设置好密码后必须执行u.save才能够生效，之后输入exit退出。
此时在之前打开的浏览器页面输入账号root密码test123456，就登录成功了。
