本文介绍如何为Gitlab服务配置邮箱，实现服务器向用户自动发送邮件。发邮件的使用场景有很多，比如，用户忘记密码后申请密码重置，用户自行注册账户时，接受邮件用于验

证账户等。

一. 配置前准备工作及说明

1. 服务器系统版本：CentOS 7

2. postfix，并在终端运行systemctl status postfix检查服务是否已在运行状态，如果显示activate则表示正在运行

1
2
3

rpm -qa | grep postfix //查看下是否已经安装好
systemctl restart postfix.service //重启postfix服务
systemctl status postfix.service //查看是否已经在线

123

2-2. 解决报错问题.

1 2	启动过程中如果报错： Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details

2-3. 解决办法:

1	vi /etc/postfix/main.cf

1

4

inet_interfaces = localhost //改成 inet_interfaces = all

# Enable IPv4, and IPv6 if supported
inet_protocols = all //改成 inet_protocols = ipv4

123

2-4. 然后再重启并开机自启动就成功

3

systemctl restart postfix.service //重启postfix服务
systemctl status postfix.service //查看是否已经在线
systemctl enable postfix.service //开机自启动

3.邮箱信息准备，以gmail邮箱为例

1	vi /etc/gitlab/gitlab.rb

3-1. 假设ancky2006@gmail.com

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.gmail.com"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "ancky2006@gmail.com"
gitlab_rails['smtp_password'] = "email-id-password"
gitlab_rails['smtp_domain'] = "smtp.gmail.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = false
gitlab_rails['smtp_pool'] = false
...
gitlab_rails['smtp_openssl_verify_mode'] = 'peer'

3-2. 修改完成并保存后，在终端使配置生效

1	gitlab-ctl reconfigure

3-3. 测试邮箱设置是否生效

1 2	gitlab-rails console Notify.test_email('info@bndstone.com','test Gitlab Email','Test').deliver_now //向测试邮箱info@bndstone.com发送邮件

3-4. 运行测试时报错,

1	Net::SMTPAuthenticationError (534-5.7.14 <https://accounts.google.com/signin/continue?sarp=1&scc=1&plt=AKgnsbt)

原因,gmail后台STMP的服务没有开启.

解决方法:
3-4-1. 进入邮箱后台.

3-4-2. 设置 – 查看所有设置
123

3-4-3. 转发和POP/IMAP
123

3-4-4. 启用IMAP
123

3-4-5. 停用2步验证

1	https://myaccount.google.com/security?pmr=1

否则下一步不会跳出来.

3-4-6. 选择允许

1	https://myaccount.google.com/lesssecureapps

123

3-4-7.

1	https://accounts.google.com/b/0/displayunlockcaptcha

123

3-5. 再测试邮箱设置是否生效
,发现已经成功发送了

1 2	gitlab-rails console Notify.test_email('info@bndstone.com','test Gitlab Email','Test').deliver_now //向测试邮箱ancky2006@gmail.com发送邮件

4. 我想换成google企业邮箱, 我的是info@bndstone.com

1	vi /etc/gitlab/gitlab.rb

gitlab_rails['smtp_tls'] = false
gitlab_rails['smtp_pool'] = false
...
gitlab_rails['smtp_openssl_verify_mode'] = 'peer'

4-2. 修改完成并保存后，在终端使配置生效

1	gitlab-ctl reconfigure

4-3. 发送测试邮箱

1 2	gitlab-rails console Notify.test_email('ancky2006@gmail','test Gitlab Email','Test').deliver_now //向测试邮箱ancky2006@gmail.com发送邮件

4-4. 运行测试时报错,

1 2	Net::SMTPAuthenticationError (535-5.7.8 Username and Password not accepted. Learn more at) Net::SMTPAuthenticationError (534-5.7.14 <https://accounts.google.com/signin/continue?sarp=1&scc=1&plt=AKgnsbt)
