sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix

4. 安装gitlab

gitlab的安装地址为：https://docs.gitlab.com/omnibus/manual_install.html

有社区版（ce）和企业版（ee），这里建议你使用企业版

安装脚本地址：https://packages.gitlab.com/gitlab/gitlab-ee/install#bash-rpm

1	curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh \| sudo bash

安装

1	yum install -y gitlab-ee

gitlab-ee会被安装/opt/gitlab目录下可通过下面命令查看

1	rpm -ql gitlab-ee \| less

5. 配置gitlab

配置项非常多，这里我们就简单配置下gitlab的地址与端口
gitlab的配置文件在/etc/gitlab/目录下，主要配置文件为gitlab.rb

详细配置可查看文档：https://docs.gitlab.com/omnibus/settings/configuration.html

更改gitlab地址

改: external_url 'http://gitlab.example.com'
为: external_url 'http://139.189.64.100:8500' #你的IP地址或域名

改: # unicorn['port'] = 8080
为: unicorn['port'] = 8500

设置邮箱
这里以163邮箱为例，QQ邮箱设置与其类似

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "test@163.com"
gitlab_rails['smtp_password'] = "password"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['gitlab_email_from'] = "test@163.com"
