# 1. 安装相关依赖
yum -y install policycoreutils openssh-server openssh-clients postfix
# 2. 启动ssh服务&设置为开机启动
systemctl enable sshd && sudo systemctl start sshd
# 3. 设置postfix开机自启，并启动，postfix支持gitlab发信功能
systemctl enable postfix && systemctl start postfix
# 4. 开放ssh以及http服务，然后重新加载防火墙列表
firewall-cmd --add-service=ssh --permanent
firewall-cmd --add-service=http --permanent
firewall-cmd --reload
# 如果关闭防火墙就不需要做以上配置
# 5. 下载gitlab包，并且安装
# 在线下载安装包：
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el6/gitlab-ce-12.4.2-ce.0.el6.x
86_64.rpm
# 安装：
rpm -i gitlab-ce-12.4.2-ce.0.el6.x86_64.rpm
# 6. 修改gitlab配置
vi /etc/gitlab/gitlab.rb
#修改gitlab访问地址和端口，默认为80，我们改为82
external_url 'http://192.168.66.100:82'
nginx['listen_port'] = 82
# 7. 重载配置及启动gitlab
gitlab-ctl reconfigure
gitlab-ctl restart
# 8. 把端口添加到防火墙
firewall-cmd --zone=public --add-port=82/tcp --permanent
firewall-cmd --reload
# 启动成功后，看到以下修改管理员root密码的页面，修改密码后，然后登录即可

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
