Springboot项目基于gitlab+docker+rancher的CI/CD Demo搭建系列(二):CentOs7安装Gitlab

安装GitLab

官网安装步骤：

https://about.gitlab.com/install/#centos-7

安装前配置，防火墙之类的
邮件配置
登陆gitlab

安装Gitlab

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

安装Postfix邮件通知

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

如果希望其他的方式，参考链接

[root@iZm5e1zao4uxbr8etk59y5Z /]# sudo systemctl start postfix

Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.

出现报错，解决方式：

修改 /etc/postfix/main.cf的设置  
  
inet_protocols = ipv4  
inet_interfaces = all

vim 操作 http://www.cnblogs.com/z-x-y/p/9198481.html

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="http:115.29.67.31" yum install -y gitlab-ee

出现下图所示，则表示安装成功。

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

  Verifying  : gitlab-ee-11.10.4-ee.0.el7.x86_64                                                                                                                                                             1/1 

Installed:
  gitlab-ee.x86_64 0:11.10.4-ee.0.el7                                                                                                                                                                            

Complete!
You have mail in /var/spool/mail/root

/etc/gitlab/gitlab.rb 修改external_url，

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

然后，刷新配置 sudo gitlab-ctl reconfigure

配置邮件

配置发件人

### Email Settings
 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

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。

邮件发送成功！

登陆gitlab

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。

修改配置

修改ip

gitlab 本身采用 80 端口，如安装前服务器有占用 80，安装完访问会报错。需更改gitlab 的默认端口，比如我们将 Gitlab 的默认端口改为 8088 。

第一步

打开阿里云服务器防火墙的 `8088 端口

//打开防火墙服务
systemctl start firewalld

//开启防火墙 8082 端口
firewall-cmd --zone=public --add-port=8082/tcp --permanent

//重启防火墙服务，让配置生效
systemctl restart firewalld

第二步

修改 Gitlab 默认端口配置打开 /etc/gitlab/gitlab.rb 文件，找到 external_url 字段，如下所示：

把 http://47.94.230.26 改为 http://47.94.230.26:8082

然后执行 gitlab-ctl reconfigure 让配置立即生效。在浏览器中访问 http://47.94.230.26:8082 , 就可以看到 Gitlab 的页面了。

访问不通

检查是否开启防火墙，端口是否开放
阿里云安全组允许端口开放

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
