1.安装依赖软件
yum install -y curl openssh-server openssh-clients postfix cronie policycoreutils-python
2.启动postfix设置postfix开机自启，并启动，postfix支持gitlab发信功能
systemctl start postfix
启动时出现报错
[root@iZ2zeemzju81bld21k77icZ ~]# journalctl -xe -- -- The start-up result is done.

解决方法：修改文件vim /etc/postfix/main.cf
inet_interfaces = localhost inet_protocols = all
修改为：
inet_interfaces = all 或者 inet_interfaces = 127.0.0.1 inet_protocols = all
保存后重启postfix服务成功，执行
systemctl enable postfix
3.下载GitLab较新版本
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.10.0-ce.0.el7.x86_64.rpm
4.安装GitLab
rpm -i gitlab-ce-11.10.0-ce.0.el7.x86_64.rpm
warning: gitlab-ce-11.10.0-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key 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.md
5.查看端口使用状态
netstat -ntlp
6. 修改gitlab配置文件 vim /etc/gitlab/gitlab.rb ，端口号填写未被占用的，默认8080
external_url 'http://ip地址:端口号'
7. 使用gitlab-ctl reconfigure 自动配置，并安装数据库，初始化信息，时间较长
gitlab-ctl reconfigure
8. 使用gitlab-ctl start 启动gitlab服务
[root@iZ ~]# gitlab-ctl start ok: run: alertmanager: (pid 17908) 1539s ok: run: gitaly: (pid 17712) 1542s ok: run: gitlab-monitor: (pid 17780) 1541s ok: run: gitlab-workhorse: (pid 17745) 1542s ok: run: logrotate: (pid 17294) 1590s ok: run: nginx: (pid 17249) 1596s ok: run: node-exporter: (pid 17768) 1541s ok: run: postgres-exporter: (pid 17925) 1538s ok: run: postgresql: (pid 16860) 1647s ok: run: prometheus: (pid 17804) 1540s ok: run: redis: (pid 16638) 1659s ok: run: redis-exporter: (pid 17788) 1540s ok: run: sidekiq: (pid 17191) 1604s ok: run: unicorn: (pid 22395) 6s
