GitLab的安装请参考：GitLab v8.17.0安装及汉化
一、修改 /etc/gitlab/gitlab.rb 文件，添加邮件服务器信息
vi /etc/gitlab/gitlab.rb
gitlab_rails['smtp_enable'] = true gitlab_rails['smtp_address'] = "smtp.163.com" gitlab_rails['smtp_port'] = 25 gitlab_rails['smtp_user_name'] = "xxx@163.com" gitlab_rails['smtp_password'] = "xxx" gitlab_rails['smtp_domain'] = “163.com” gitlab_rails['smtp_authentication'] = "login" gitlab_rails['smtp_enable_starttls_auto'] = true gitlab_rails['gitlab_email_from'] = "xxx@163.com" user["git_user_email"] = "xxx@163.com"
二、使配置生效
sudo gitlab-ctl reconfigure
