1. 安装GitLab
wget https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh
sudo os=el dist=8 bash ./script.rpm.sh
sudo EXTERNAL_URL="http://xxx.xxx.xx.xx" yum install -y gitlab-ce
2. 查启动状态，等待个二十来分钟
gitlab-ctl tail
3. 关闭防火墙
service firewalld stop
4. 查初始密码，测试登录，用户名为root
cat /etc/gitlab/initial_root_password
5. 设置开机自启动
systemctl enable gitlab-runsvdir.service
6. 给gitlab配置ssl证书
vim /etc/gitlab/gitlab.rb
external_url 'https://your-domain.com'
nginx['redirect_http_to_https'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/server.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/server.key"
gitlab-ctl reconfigure
gitlab-ctl restart
