1.先按照官方教程
https://about.gitlab.com/downloads/#centos7
大概內容如下：
1. Install and configure the necessary dependencies
If you install Postfix to send email please select 'Internet Site' during setup. Instead of using Postfix you can also use Sendmail or configure a custom SMTP server and configure it as an SMTP server.
On CentOS, the commands below will also open HTTP and SSH access in the system firewall.
安裝ssh
sudo yum install curl policycoreutils openssh-server openssh-clients sudo systemctl enable sshd sudo systemctl start sshd
安裝postfix sudo yum install postfix sudo systemctl enable postfix sudo systemctl start postfix
配置防火牆 sudo firewall-cmd --permanent --add-service=http sudo systemctl reload firewalld
2. Add the GitLab package server and install the package
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install gitlab-ce
If you are not comfortable installing the repository through a piped script, you can find the entire script here and select and download the package manually and install using
curl -LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-XXX.rpm/download
rpm -i gitlab-ce-XXX.rpm
3. Configure and start GitLab
sudo gitlab-ctl reconfigure
新建用戶可能無法同步或者push，需要管理員設置存儲庫權限
選擇master+developer就行了，不要點擊【unprotect】
修改http端口
gitlab默認是80端口，修改下面3個文件，可以很容易看到端口修改的地方
vi /opt/gitlab/embedded/conf/nginx.conf
vi /var/opt/gitlab/gitlab-rails/etc/gitlab.yml
vi /var/opt/gitlab/nginx/conf/gitlab-http.conf
重啟服務
gitlab-ctl restart
