Gitlab
GitHub是公開的倉庫，一些企業和公司的代碼不方便放到上面，就可以選擇搭建一個自己的私有倉庫，可以搭建Gitlib來實現。
1.Git服務器的搭建
[root@antong ~]# yum install -y git
[root@antong ~]# git config --global user.name "antong"
[root@antong ~]# git config --global user.email "1172734664@qq.com"
//添加git用戶，並且設置shell為/usr/bin/git-shell,目的是為了不讓git用戶遠程登陸
[root@antong ~]# useradd -s /usr/bin/git-shell git
[root@antong ~]# cd /home/git/
//創建authorized_keys文件，並更改屬主、屬組和權限，用來存客戶端機器上的公鑰
[root@antong git]# mkdir .ssh
[root@antong git]# touch .ssh/authorized_keys
[root@antong git]# chown -R git.git .ssh
[root@antong git]# chown 600 .ssh/authorized_keys
[root@antong git]# ll .ssh/authorized_keys
-rw-r--r--. 1 600 git 0 Sep 2 21:40 .ssh/authorized_keys
//定好存儲Git倉庫的目錄，比如 /data/gitpub
[root@antong git]# mkdir /data/gitpub
[root@antong git]# cd /data/gitpub/
[root@antong gitpub]# git init --bare sample.git
Initialized empty Git repository in /data/gitpub/sample.git/
[root@antong gitpub]# chown -R git.git sample.git/
[root@antong gitpub]# ll
total 0
drwxr-xr-x. 7 git git 119 Sep 2 21:42 sample.git
以上操作是在Git服務器上操作，平時Git服務器是不需要開發人員登錄修改代碼的，它僅僅是充當着一個服務器的角色，就像GitHub一樣，平時操作都是在我們自己的機器上操做的。
//首先要把客戶端上的公鑰放到git服務器/home/git/.ssh/authorized_keys文件里
[root@client ~]# ssh-keygen //按3次回車
[root@client ~]# scp /root/.ssh/id_rsa.pub 192.168.200.10:/home/git/.ssh/authorized_keys
//在客戶端上克隆遠程倉庫
[root@client ~]# git clone git@192.168.200.10:/data/gitpub/sample.git
Cloning into 'sample'...
warning: You appear to have cloned an empty repository.
[root@client ~]# ls
anaconda-ks.cfg sample
//此時就可以在當前目錄下生成一個sample的目錄，這個就是我們克隆的遠程倉庫了。進入到這里面，可以開發一些代碼，然后push到遠程，比如git push origin master。
2.GitLab的使用
GitLab官網：https://about.gitlab.com/gitlab-com/
官方安裝文檔：https://about.gitlab.com/installation/?version=ce#centos-7 (ce/ee)
要求服務器內存不少於2 GB。
[root@client ~]# vim /etc/yum.repos.d/gitlab.repo //加入如下內容
[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1
[root@client ~]# yum clean all //清理yum源
[root@client ~]# yum repolist //查看是否配置成功
[root@antong ~]# yum install -y gitlab-ce.x86_64
[root@antong ~]# gitlab-ctl reconfigure //重新加載
[root@antong ~]# netstat -lnpt //查看監聽端口
[root@antong ~]# netstat -lnpt

使用瀏覽器訪問Gitlab，輸入IP地址即可
默認管理員root，無密碼，它會讓我們去定義一個密碼，至少8位數
