Centos7搭建gitlab环境 前言

前言

在学习Gitlab的环境搭建之前,首先需要了解Git,Gitlab,GitHub他们三者之间的关系

Git 它是一个源代码版本控制系统,可让您在本地跟踪更改并从远程资源推送或提取更改。
GitHub 是一项公开可用的免费服务,它要求所有代码(除非您有付费帐户)公开。 任何人都可以看到您推送给GitHub的代码并提供改进建议。
GitLab是一种类似github的服务,组织可以使用它来提供git存储库的内部管理。 它是一个自我托管的Git-repository管理系统,可以保持用户代码的私密性,并且可以轻松地部署代码的更改。

简单来说,github是全世界最大的开源的gay友平台,适合免费公开的代码。gitlab是搭建本公司的代码管理平台,适合私有的平台代码管理。
因为本公司的代码不想被其它人看到,这就需要搭建一个本公司的gitlab平台,供公司内部人员使用。

环境准备:

centos 7
gitlab 10

安装依赖包

GitLab 10.x之后添加多了一些依赖,并且要启动sshd服务,所以我们先添加依赖,启动sshd,为防火墙添加服务

sudo yum install -y curl policycoreutils-python openssh-server openssh-clients 
sudo systemctl enable sshd 
sudo systemctl start sshd  

# 防火墙这2步可以不用管 # sudo firewall-cmd –permanent –add-service=http # sudo systemctl reload firewalld

postfix的产生是为了替代传统的sendmail.相较于sendmail,postfix在速度。性能和稳定性上都更胜一筹。
如今眼下许多的主流邮件服务事实上都在採用postfix. 当我们须要一个轻量级的的邮件server是,postfix不失为一种选择。

  • postfix想要作用的范围是广大的Internet用户。试图影响大多数的Internet上的电子邮件系统,因此它是免费的。
  • postfix在性能上大约比sendmail快三倍。一部执行postfix的台式PC每天能够收发上百万封邮件。
  • postfix是sendmail兼容的,从而使sendmail用户能够非常方便地迁移到postfix。Postfix支持/var[/spool]/mail、/etc/aliases、 NIS、和 ~/.forward 文件。
  • postfix被设计成在重负荷之下仍然能够正常工作。当处理的邮件数目增长时,postfix执行的进程不会跟着添加。
  • postfix是由超过一打的小程序组成的,每一个程序完毕特定的功能。

gitlab配置需要用到邮件发送,所以先安装postfix

yum -y install postfix

安装完之后,启动postfix

systemctl start postfix

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.

解决办法,vim打开/etc/postfix/main.cf,修改如下两项,修改之前可以先备份下

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

修改完成后,再次启动,就不会报错了,设置postfix为开机自启动

systemctl enable postfix

查看启动状态,看到 Active: active (running) 就是已经正常启动了

systemctl status postfix

完整的操作如下

[root ~]# yum -y install policycoreutils-python openssh-server openssh-clients
[root ~]# systemctl enable sshd 
[root ~]# systemctl start sshd

[root ~]# yum -y install postfix
[root ~]# 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.

gitlab安装

centos 7系统的下载地址:https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7

找个最新版去下载gitlab-ce-11.6.3-ce.0.el7.x86_64.rpm

下载rpm包并安装

# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.0.0-ce.0.el7.x86_64.rpm

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

安装完成之后,会出现gitlab官方文档地址https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

配置并启动gitlab-ce

gitlab安装完成后,需要设置一个访问地址(或域名),打开/etc/gitlab/gitlab.rb将默认的external_url = 'http://git.example.com'修改为自己的IP地址:http://xxx.xx.xxx.xx

# vim /etc/gitlab/gitlab.rb

原来默认的external_url

## GitLab URL
##! URL on which GitLab will be reachable. ##! For more details on configuring external_url see: ##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab external_url 'http://git.example.com'

修改成自己定义的url地址,端口自己设置一个,别和已有的冲突了

## GitLab URL
##! URL on which GitLab will be reachable. ##! For more details on configuring external_url see: ##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab external_url 'http://47.104.x.x:8100'

修改完成后:wq保存退出,执行以下命令,让配置生效

# gitlab-ctl reconfigure

启动Gitlab

# gitlab-ctl start

# gitlab-ctl start
ok: run: gitaly: (pid 6638) 186s
ok: run: gitlab-monitor: (pid 6656) 186s ok: run: gitlab-workhorse: (pid 6659) 186s ok: run: logrotate: (pid 6703) 185s ok: run: nginx: (pid 6709) 185s ok: run: node-exporter: (pid 6715) 184s ok: run: postgres-exporter: (pid 6720) 184s ok: run: postgresql: (pid 7324) 44s ok: run: prometheus: (pid 6752) 171s ok: run: redis: (pid 6761) 171s ok: run: redis-exporter: (pid 6765) 170s ok: run: sidekiq: (pid 7299) 45s ok: run: unicorn: (pid 7476) 18s

启动完成后,在浏览器输入http://47.104.x.x:8100,就是gitlab的登录首页了,如果出现502页面,需修改默认的8080端口

502问题

打开gitlab首页出现502问题

出现这个问题,主要是因为8080端口被占用,之前安装tomcat默认的是8080端口,netstat -ntpl查看端口情况

# netstat -ntpl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 127.0.0.1:9100          0.0.0.0:* LISTEN 6715/node_exporter tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 801/java tcp 0 0 0.0.0.0:8060 0.0.0.0:* LISTEN 6709/nginx: master tcp 0 0 127.0.0.1:9121 0.0.0.0:* LISTEN 6765/redis_exporter tcp 0 0 127.0.0.1:9090 0.0.0.0:* LISTEN 6752/prometheus tcp 0 0 127.0.0.1:9187 0.0.0.0:* LISTEN 6720/postgres_expor tcp 0 0 0.0.0.0:8100 0.0.0.0:* LISTEN 6709/nginx: master tcp 0 0 127.0.0.1:8101 0.0.0.0:* LISTEN 7495/unicorn master tcp6 0 0 :::3306 :::* LISTEN 1370/mysqld 

杀掉8080端口即可,8080端口对应的pip是801

# kill -9 801

重启下服务,刷新页面就可以访问了

# gitlab-ctl restart

为了避免8080端口冲突问题,可以修改下unicorn的默认端口,vim打开/etc/gitlab/gitlab.rb配置文件

新增一项unicorn['port'] = 8101,修改后内容如下

## GitLab URL
##! URL on which GitLab will be reachable. ##! For more details on configuring external_url see: ##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab external_url 'http://47.104.x.x:8100' unicorn['port'] = 8101

修改完成后:wq保存退出,执行gitlab-ctl reconfigure命令,让配置生效,再重新启动服务

# gitlab-ctl reconfigure
# gitlab-ctl stop
# gitlab-ctl start

接着在浏览器访问就能看的gitlab登录首页了

gitlab配置查看

gitlab的配置主要是etc/gitlab/gitlab.rb下的两个地方

external_url 'http://47.104.x.x:8100'

unicorn['port'] = 8101

查看更多配置信息可以,在/opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml查看具体的详情

  gitlab:
    ## Web server settings (note: host is the FQDN, do not include http://)
    host: 47.104.x.x  port: 8100  https: false

相关操作

启动服务:gitlab-ctl start
查看状态:gitlab-ctl status
停掉服务:gitlab-ctl stop
重启服务:gitlab-ctl restart
让配置生效:gitlab-ctl reconfigure
