Nginx做反向代理和缓存服务器的配置文件

创建缓存目录

mkdir -p /data/cdn_cache

1 缓存服务配置文件

[root@linux-node1 ~]#/etc/nginx/conf.d/proxy.conf 定义一个名称为cache_one的缓存zone（名称可以自定义）

#CDNproxy_temp_path /data/cdn_cache/proxy_temp_dir;proxy_cache_path /data/cdn_cache/proxy_cache_dir levels=1:2 keys_zone=cache_one:50m inactive=1d max_size=1g;proxy_connect_timeout 5;proxy_read_timeout 60;proxy_send_timeout 5;proxy_buffer_size 16k;proxy_buffers 4 64k;proxy_busy_buffers_size 128k;proxy_temp_file_write_size 128k;proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_404;

2 反向代理配置文件

定义一个名称为www.example.com.pool反向代理组

[root@linux-node1 ~]# /etc/nginx/conf.d/upstream.conf

upstream www.example.com.pool{        server 192.168.56.12:8080 weight=10 max_fails=3;        server 192.168.56.13:8080 weight=10 max_fails=3;}

3 网站配置文件

[root@linux-node1 ~]# vim /etc/nginx/conf.d/www.example.com.conf

定义一个缓存区location 指定使用缓存配置文件中定义的cache_one zone 缓存以 gif|jpg|png|html|htm|css|js|ico|swf|pdf结尾的文件 定义一个回源区location 如果缓存区没有，就到回源区访问

server{    listen 80;    server_name www.example.com;    access_log logs/www.example.com-access.log main;    location ~ .*\.(gif|jpg|png|html|htm|css|js|ico|swf|pdf)$    {	#Proxy 	proxy_redirect off;        proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;        proxy_set_header            Host $host;        proxy_set_header            X-real-ip $remote_addr;        proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;        proxy_pass    www.example.com.pool;	#Use Proxy Cache	proxy_cache cache_one;	proxy_cache_key "$host$request_uri";	add_header Cache "$upstream_cache_status";	proxy_cache_valid  200 304 301 302 8h;	proxy_cache_valid 404 1m;	proxy_cache_valid  any 2d;    }    location /    {                proxy_redirect off;                proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;                proxy_set_header            Host $host;                proxy_set_header            X-real-ip $remote_addr;                proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;                proxy_pass    www.example.com.pool;                client_max_body_size 40m;                client_body_buffer_size 128k;                proxy_connect_timeout 60;                proxy_send_timeout 60;                proxy_read_timeout 60;                proxy_buffer_size 64k;                proxy_buffers 4 32k;                proxy_busy_buffers_size 64k;    }}
