使用Nginx反向代理,自建CDN加速节点
安装
1、安装Nginx
#这里使用的是军哥的lnmp
wget -c http://www.321dz.com/shell/lnmp1.4.tar.gz && tar zxf lnmp1.4.tar.gz && cd lnmp1.4 && ./install.sh nginx
2、CDN配置
假如我需要对www.331dz.com
搭建CDN
节点,数据放在192.168.1.100
,需要先修改hosts
指向,告知CDN
节点去哪里去获取网站数据,也就是回源地址,做如下修改:
vi /etc/hosts
192.168.1.100 www.331dz.com
然后创建nginx
配置文件321dz.com.conf
。
#创建缓存目录
mkdir -p /data/wwwroot/caches/www.321dz.com
#设置缓存目录权限
chown -R www:www /data/wwwroot/caches/www.321dz.com
#创建moerats.com.conf
vi /usr/local/nginx/conf/vhost/321dz.com.conf
在moerats.com.conf
中添加下面的内容,缓存目录/缓存时间请根据实际情况调整。
proxy_cache_path /data/wwwroot/caches/www.321dz.com levels=1:2 keys_zone=Rats:50m inactive=30m max_size=50m;
server {
listen 80;
server_name www.321dz.com;
charset utf-8,gbk;
location / {
proxy_set_header Accept-Encoding "";
proxy_pass https://www.321dz.com;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cache Rats;
proxy_cache_valid 200 304 30m;
proxy_cache_valid 301 24h;
proxy_cache_valid 500 502 503 504 0s;
proxy_cache_valid any 1s;
proxy_cache_min_uses 1;
expires 12h;
}
}
参数说明:
/data/wwwroot/caches/www.321dz.com:为缓存目录
levels:指定该缓存空间有两层hash目录,第一层目录为1个字母,第二层为2个字母。
keys_zone=Rats:50m:为缓存空间起个名字,这里取名为“Rats”,后面的50m指内存缓存空间
inactive=30m:如果30分钟内该资源没有被访问则删除
max_size=50m:指硬盘缓存大小为50MB
proxy_cache_valid:指定状态码缓存时间,前面写状态码,后面写缓存时间。
然后重启Nginx
生效
lnmp nginx reload
3、Https配置
如果是https
网站,配置文件参考:
proxy_cache_path /data/wwwroot/caches/www.321dz.com levels=1:2 keys_zone=Rats:50m inactive=30m max_size=50m;
server {
listen 443 ssl http2;

ssl_certificate_key /home/321dz.com.key;
ssl_session_timeout 1d;
ssl_session_cache builtin:1000 shared:SSL:10m;
ssl_dhparam /data/ssl/dhparam.pem;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';
ssl_prefer_server_ciphers on;
ssl_stapling on;
ssl_stapling_verify on;
server_name www.321dz.com;
access_log /data/wwwlogs/321dz.com_nginx.log combined;
charset utf-8,gbk;
location / {
proxy_set_header Accept-Encoding "";
proxy_pass https://www.321dz.com;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cache Rats;
proxy_cache_valid 200 304 30m;
proxy_cache_valid 301 24h;
proxy_cache_valid 500 502 503 504 0s;
proxy_cache_valid any 1s;
proxy_cache_min_uses 1;
expires 12h;
}
}
server {
listen 80 default_server;
return 301 https://$host$request_uri;
}
你也可以使用多台VPS
,利用CloudXNS
智能解析,将不同地区的DNS
解析到最近的VPS
上,进行CND
加速。
