一、修改 /etc/gitlab/gitlab.rb 檔案，新增郵件伺服器資訊

SMTP settings

例如163 郵件伺服器

gitlab_rails[‘smtp_enable’] = true
gitlab_rails[‘smtp_address’] = “smtp.163.com”
gitlab_rails[‘smtp_port’] = 25
gitlab_rails[‘smtp_user_name’] = “[email protected]”
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’] = “[email protected]”
user[“git_user_email”] = “[email protected]”

二、執行 gitlab-ctl reconfigure 命令使配置生效

gitlab-ctl reconfigure
