Gitlab 如何通过smtp方式配置邮件通知提醒

1，首先切换到gitlab安装目录并查找smtp配置文件：

[root@21yunwei gitlab]#vim  /etc/gitlab/gitlab.rb
注：基本所有关于gitlab的配置都是修改这个配置文件，比如web入口地址以及端口、smtp等等。

# see https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/doc/settings/smtp.md#smtp-settings
# Use smtp instead of sendmail/postfix.
 
 gitlab_rails['smtp_enable'] = true
 gitlab_rails['smtp_address'] = "mail.21yunwei.com"
 gitlab_rails['smtp_port'] = 25
 gitlab_rails['smtp_user_name'] = "gitlab"
 gitlab_rails['smtp_password'] = "xxxxxx"
 gitlab_rails['smtp_domain'] = "21yunwei.com"
 gitlab_rails['smtp_authentication'] = "login"
 gitlab_rails['smtp_enable_starttls_auto'] = true
 gitlab_rails['smtp_tls'] = false
 gitlab_rails['smtp_openssl_verify_mode'] = 'none' # Can be: 'none', 'peer', 'client_once', 'fail_if_no_peer_cert', see http://api.rubyonrails.org/classes/ActionMailer/Base.html
 gitlab_rails['smtp_ca_path'] = "/etc/ssl/certs"
 gitlab_rails['smtp_ca_file'] = "/etc/ssl/certs/ca-certificates.crt"
修改之后重新配置，生效即可使用:gitlab-ctl reconfigure
重启gitlab：gitlab-ctl restart
注意，一些朋友忘记配置环境变量，导致该命令不生效。请修改/etc/profile讲gitlab-ctl的bin路径加进去并source /etc/profile生效。
现在添加或改动用户，就可以看到gitlab@21yunwei.com发送邮件了
