Centos6.5安装let\'s encrypt for xampp

Let\'s Encrypt是什么？


Let\'s Encrypt要求站点要有虚拟主机，所以第一步就是把站点直接连接，变为虚拟主机方式。
建立一个文件夹放置虚拟主机配置文件
mkdir /opt/lampp/etc/myVhost

在/opt/lampp/etc/httpd.conf文件末尾添加
httpd.conf:
IncludeOptional etc/myVhost/*.conf

建立虚拟主机配置文件
vi /opt/lampp/etc/myVhost/example.com.conf

example.com.conf:
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
DocumentRoot /opt/lampp/htdocs
ErrorLog /opt/lampp/logs/example.com/error.log
</VirtualHost>

mkdir /opt/lampp/logs/example.com#建立日志目录

虚拟主机配置完，重启lampp
cd /opt/lampp
./lampp restart #也可只单独重启Apache

2.下载let\'s encrypt程序
yum install epel-release #安装环境
yum install git #安装环境
git clone https://github.com/letsencrypt/letsencrypt /opt/letsencrypt#下载到let\'s encrypt到/opt/letsencrypt

3.下载证书
cd /opt/letsencrypt
./certbot-auto certonly --webroot-w/opt/lampp/htdocs -d www.example.com

#由于lampp是单独配置的环境，所以只下载证书。

证书下载成功会出现下面类似的提示：
IMPORTANT NOTES:
- If you lose your account credentials, you can recover through
e-mails sent to user@example.com.
- Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/example.com/fullchain.pem. Your cert
will expire on 2016-04-21. To obtain a new version of the
certificate in the future, simply run Let\'s Encrypt again.
- Your account credentials have been saved in your Let\'s Encrypt
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 Let\'s
Encrypt so making regular backups of this folder is ideal.

4.配置Apache，其实也就是添加证书位置。
vi /opt/lampp/etc/myVhost/example.com.conf

example.com.conf:
<VirtualHost *:443>
ServerName example.com
ServerAlias www.example.com
DocumentRoot /opt/lampp/htdocs
ErrorLog /opt/lampp/logs/example.com/error.log
SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
</VirtualHost>

5.设置http跳转至https
到第4步，没有意外的话，应该能在浏览器看到小锁了。不想用http，设置一个跳转就行了。

6.let\'s encrypt证书只有90天的期限，所以定期更新证书很有必要，不过还没有实践过，把网上一些资料先copy下来。
crontab -e
30 2 ** 1 /opt/letsencrypt/letsencrypt-auto renew >>/opt/lampp/logs/example.com/le-renew.log#定时每周一 2：30更新证书

7.更新Let’s Encrypt程序，同样没有实践过，先保存。
cd /opt/letsencrypt
git pull
