CentOS7系统下GitLab的安装

1、安装和配置必须的依赖

1 sudo yum install curl policycoreutils openssh-server openssh-clients  
2 sudo systemctl enable sshd  
3 sudo systemctl start sshd  
4 sudo yum install postfix  
5 sudo systemctl enable postfix  
6 sudo systemctl start postfix  
7 sudo firewall-cmd --permanent --add-service=http  
8 sudo systemctl reload firewalld  

2、添加GitLab包服务，然后安装它

1 curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash  
2 sudo yum install gitlab-ce  

3、配置和启动GitLab

1 sudo gitlab-ctl reconfigure

启动完成后，在浏览器访问你机器的IP地址，然后，修改密码，注册用户，最后登录进去。

搭建的GitLab服务就基本完成了.
