安装GitLab（来源：开源中国）

1.打开防火墙的http和ssh访问

sudo yum install -y curl policycoreutils-python openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd
sudo firewall-cmd --permanent --add-service=http
sudo systemctl reload firewalld

2.安装Postfix邮件通知

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

出现报错，解决方式：

修改 /etc/postfix/main.cf的设置  
  
inet_protocols = all
inet_interfaces = all 

3.执行安装gitlab，EXTERNAL_URL为服务器的IP,也可设置为域名。端口默认为80

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

sudo EXTERNAL_URL="ip" yum install -y gitlab-ee

/etc/gitlab/gitlab.rb 修改external_url，然后，刷新配置 sudo gitlab-ctl reconfigure

external_url 'http://XX.XX.XX.XX'

4.配置邮件服务器/etc/gitlab/gitlab.rb

配置发件人

gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = 'chenglitao@wangxiaobao.com'
gitlab_rails['gitlab_email_display_name'] = 'Gitlab'

配置服务器

 gitlab_rails['smtp_enable'] = true
 gitlab_rails['smtp_address'] = "smtp.XXX.com"
 gitlab_rails['smtp_port'] = 465
 gitlab_rails['smtp_user_name'] = "XXX@XXX.com"
 gitlab_rails['smtp_password'] = "XX"
 gitlab_rails['smtp_domain'] = "XX.com"
 gitlab_rails['smtp_authentication'] = "login"
 gitlab_rails['smtp_enable_starttls_auto'] = true
 gitlab_rails['smtp_tls'] = true

sudo gitlab-ctl reconfigure，刷新配置

测试发送邮件

gitlab-rails console


#进入控制台，然后发送邮件
Notify.test_email('593482670@qq.com', '邮件标题', '邮件正文').deliver_now

出现如下报错：OpenSSL::SSL::SSLError (hostname "smtp.wangxiaobao.com" does not match the server certificate)

解决办法：修改/etc/gitlab/gitlab.rb文件

gitlab_rails['smtp_openssl_verify_mode'] = 'none'

sudo gitlab-ctl reconfigure，重新测试。

5.登录

登陆external_url配置的地址，第一次打开需要设置密码，默认用户root,密码即为刚才设置的密码。

6.常用命令

//启动
sudo gitlab-ctl star

//停止
sudo gitlab-ctl stop

//重启
sudo gitlab-ctl restart

//使更改配置生效
sudo gitlab-ctl reconfigure
