centos7搭建个人的git pages

Git Pages是结合git服务操作的web网页托管平台。通过git提交再结合git hook脚本就能很好的将提交的文件上传到web服务虚拟目录里。但是Github、Netlify、Coding等已经提供了免费git pages服务，为什么还要自己在vps上折腾搭建git pages呢？因为这些服务商提供的git pages是有限制的，比如空间容量相对较小、对动态网页支持不完善或者没有、访问速度较慢等。那么自建的git pages的优势就显现出来了。下面就介绍怎么一步步搭建该服务。

¶1、安装Git

1 2	$ yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-devel $ yum install git

接下来我们创建一个git用户组和用户，用来运行git服务：

1 2	$ groupadd git $ useradd git -g git

¶2、创建ssh证书登录

收集所有需要登录的用户的公钥，公钥位于id_rsa.pub文件中，把我们的公钥导入到/home/git/.ssh/authorized_keys文件里，一行一个。

如果没有该文件创建它：

$ mkdir /home/git/.ssh
$ chmod 755  /home/git/.ssh
$ touch /home/git/.ssh/authorized_keys
$ chmod 644  /home/git/.ssh/authorized_keys

客户机

1 2	#copy客户端的秘钥到vps的/home/git/.ssh/authorized_keys $ cat ~/.ssh/id_rsa.pub

¶3、搭建git仓库

$ mkdir -p /data/git
$ chown git:git /data/git
$ chgrp -R 755 /data/git
$ cd /data/git
$ git init --bare blog.git
$ chown -R git:git blog.git
$ vim /data/git/blog.git/hooks/post-receive

1 2	#!/bin/bash git --work-tree=/data/blog --git-dir=/data/git/blog.git checkout -f

1	$ chmod +x /data/git/blog.git/hooks/post-receive

¶4、搭建web服务

需要安装好nginx，可以参考我的另一篇文章《nginx学习笔记》。

$ mkdir -p /data/blog
$ chmod -R 777 /data/blog/
$ vim /etc/nginx/conf.d/blog.conf

server {
        listen  80;
        server_name     qcmoke.top; #填写个人域名
        location        / {
                root    /data/blog; #配置web根目录
                index   index.html;
        }
}

1	$ nginx -s reload

¶5、配置https服务

#下载certbot-auto
$ wget https://dl.eff.org/certbot-auto
#给予certbot-auto可执行权限
$ chmod a+x ./certbot-auto

交互式的配置过程


#### 这里给qcmoke.top和*.qcmoke.top都设置ssl证书，让qcmoke.top以及其所有子域名都能使用同一个证书，注意域名改为自己的域名
./certbot-auto --server https://acme-v02.api.letsencrypt.org/directory -d "*.qcmoke.top" -d "qcmoke.top" --manual --preferred-challenges dns-01 certonly

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/qcmoke.top/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/qcmoke.top/privkey.pem
   Your cert will expire on 2018-12-28. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot-auto
   again. To non-interactively renew *all* of your certificates, run
   "certbot-auto renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:
   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

配置PFS秘钥（可选）

生成Perfect Forward Security（PFS）键值，这步其实不做也可以。

配置nginx web服务

1	$ vim /etc/nginx/conf.d/blog.conf

需求：http://qcmoke.top、http://www.qcmoke.top、https://qcmoke.top都重定向到https://www.qcmoke.top，并且图片都能压缩传输。

重载配置

1	$ nginx -s reload

¶6、测试

客户机

$ git clone git@qcmoke.top:/data/git/blog.git
$ cd blog/
$ echo "<h1>Qcmoke Bolg</h1>" >> index.html
$ git add . 
$ git commit -m "init my blog"
$ git push -u origin master

之后浏览器访问http://qcmoke.top就能访问到push到服务器的index.html页面了。
