nginx可以实现基于硬盘缓存的反向代理服务
通过proxy_cache和fastcgi_cache两个功能模块完成配置
-----
本例：
nginx反向代理服务器192.168.80.81
web服务器192.168.80.82
win7客户机 192.168.80.79
-----
### web服务器192.168.80.82 配置：
安装简单的httpd，提供web服务即可
-----
### nginx反向代理服务器192.168.80.81配置：
1.上传反向代理插件、软件和解压：
tar xzvf ngx_cache_purge-2.3.tar.gz -C /opt/
tar xzvf pcre-8.41.tar.bz2 -C /opt/
tar xzvf nginx-1.13.5.tar.gz -C /opt/
yum install -y zlib-devel
2.编译安装nginx
cd /opt/nginx-1.13.5
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module \
--with-pcre=/opt/pcre-8.41 \
--add-module=/opt/ngx_cache_purge-2.3
make && make intall
useradd -M nginx
cd /usr/local/nginx/conf
vi nginx.conf
清除原内容，插入以下：
user nginx nginx;
worker_processes 1;
error_log logs/error.log crit;
worker_rlimit_nofile 65535;
events {
use epoll;
worker_connections 65535;
}
http {
include mime.types;
default_type application/octet-stream;
charset utf-8;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;
client_body_buffer_size 512k;

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_temp_path /var/cache/nginx/cache_temp;
proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2 keys_zone=cache_one:200m inactive=1d max_size=30g;
upstream backend_server{
server 192.168.80.185:80 weight=1 max_fails=2 fail_timeout=30s;
}
#gzip on;
server {
listen 80;
server_name test 192.168.80.81;
index index.html index.htm;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_next_upstream http_502 http_504 error timeout invalid_header;
proxy_cache cache_one;
proxy_cache_valid 200 304 12h;
proxy_cache_key $host$uri$is_args$args;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_pass http://backend_server;
expires 1d;
}
location ~/purge(/.*) {
allow 127.0.0.1;
allow 192.168.80.0/24;
deny all;
proxy_cache_purge cache_one $host$1$is_args$args;
}
location ~\.(php|jsp|cgi)?$ {
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_pass http://backend_server;
}
access_log off;
}
}
3.启动nginx
创建缓存目录
mkdir -p /var/cache/nginx/cache_temp
mkdir /var/cache/nginx/proxy_cache
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
nginx -t 检查配置文件
nginx
netstat -anpt | grep nginx
service firewalld stop
setenforce 0
测试
验证代理：win7客户机80.79访问nginx反向代理服务器地址80.81
可以看到web服务器80.82内容
验证缓存：在nginx反向代理服务器192.168.80.81上
ls /var/cache/nginx/proxy_cache //使TAB键向后补全文件夹，可以验证1位文件夹名下的两位文件夹名下的缓存文件
http://192.168.80.81/purge/ //用来清除缓存。
ls /var/cache/nginx/proxy_cache/ //使TAB键向后补就补不全了
