前言

Git — 无需多说，2018年还不知道Git的程序猿不是好程序猿

Git诞生于2005年，大神Linus的作品，Github诞生于2008年，没有Git就没有GitHub，Github已成为全球最大的代(tong)码(xing)开(jiao)源(you)社(wang)区(zhan)，注册免费用户即可在Github上免费托管开源代码，如需建立私有仓库必须付费。那么Gitlab又是什么？

GitLab和GitHub一样属于第三方基于Git开发的作品，免费且开源（https://github.com/gitlabhq/gitlabhq基于MIT协议），与Github类似，可以注册用户，任意提交你的代码，添加SSHKey等等。不同的是，GitLab是可以部署到自己的服务器上，数据库等一切信息都掌握在自己手上，适合团队内部协作开发，你总不可能把团队内部的智慧总放在别人的服务器上吧？简单来说可把GitLab看作个人版的GitHub。

搭建GitLab

环境配置

系统：Red-Hat系列CentOS 7.x-x86_64（笔者采用的是CentOS7.2）

CPU：建议双核以上

内存：2GB（官方建议4GB以上，请看下图官方给出的建议）

安装

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-clientssudo systemctlenablesshdsudo systemctl start sshd sudo firewall-cmd –permanent –add-service=httpsudo systemctl reload firewalld

GitLab官方文档中有多种安装方式，分别为deb，rpm，node，python，gem。详情请看：https://packages.gitlab.com/gitlab/gitlab-ce/install

笔者采用的是rpm安装方式，命令行下输入

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

然后静静等待完成，此时细心的同学会发现这是个shell？ 没错，这是官方的一个shell，有兴趣的同学可以研究一下这个shell

好了，完成之后输入

yum search gitlab

可看到库已经添加进来，注意是上边那个，我第一次添加的时候添加错成ee版，尴尬脸，ee版是企业版，ce版是社区版，从这可以看到GitLab包含了 Nginx，PostgreSQL数据库，还有Redis

有了这个之后就可以直接安装啦，输入

yum install -y gitlab

又经历一次静静的等待直到出现

install GitLab.jpg

此时此刻，GitLab 终于装上了！ 然后按照提示 修改 /etc/gitlab/gitlab.rb 把 external_url 中的地址修改一下

修改配置地址.jpg

完成之后执行

gitlab-ctl reconfigure

继续静静地等待配置和启动服务完成….

终于等到完成了，立马在浏览器中输入地址，结果..

服务器502.jpg

甚至出现无法连接服务器，这并不是我想要的结果！ 于是我立马看了下gitlab的状态

gitlab-ctl status

发现并没有什么问题啊，一切正常，这时候心中千万只草泥马在奔驰

查阅一番资料之后，也就是文章一开始的配置之后发现是因为个人服务器配置不够，服务跑不起来.

最后实在不死心，跑了一趟虚拟机终于给跑起来了，至此安装GitLab结束

使用

第一次进入页面的时候会提示你修改管理员密码，按照步骤修改密码登录就可以了

登录之后创建仓库，可见Gitlab还可以创建自己的私有库

也可像Github一样查看哪个日期有多少次提交

有过Github的使用经验的话使用起来就已经是很方便的了。

后记

挺久前就想搭一个自己的GitLab，由于时间精力有限（其实就是懒），到最近想到挺想玩一下然后找的资料都乱七八糟的，所以踩了点坑，到最后搭起来，希望本文对要搭GitLab的同学有所帮助，然后需要汉化的话找相对应版本的汉化包进行覆盖，查看GitLab版本命令：

cat /opt/gitlab/embedded/service/gitlab-rails/VERSION

另外被qiang住的同学可使用清华大学的开源软件镜像 ：https://mirror.tuna.tsinghua.edu.cn/help/gitlab-ce
