nginx反向代理实现和分析

nginx反向代理实现和分析

一．安装

安装nginx

yum install nginx

二．配置

注：假设有两个配置

location /ibp/ {

proxy_pass http://dmx.xx.ha.yc/ibp/;

}

location /ibp/ {

proxy_pass http://dmx.xx.ha.yc/ibp;

}

第一个代理后是http://dmx.xx.ha.yc/ibp/manage/,第二个代理后是http://dmx.xx.ha.yc/ibpmanage/

Nginx主配置文件示例

[root@localhost nginx]# cat /etc/nginx/nginx.conf

user nginx;

worker_processes auto;

error_log /var/log/nginx/error.log notice;

pid /run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {

worker_connections 1024;

}

http {

log_format proxy_log '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for" '

'Client Request URI: $request_uri '

'Proxy Target: $proxy_host$request_uri';

access_log /var/log/nginx/access.log proxy_log;

sendfile on;

tcp_nopush on;

keepalive_timeout 65;

types_hash_max_size 4096;

include /etc/nginx/mime.types;

default_type application/octet-stream;

include /etc/nginx/conf.d/*.conf;

server {

listen 80;

listen [::]:80;

server_name _;

root /usr/share/nginx/html;

# Load configuration files for the default server block.

include /etc/nginx/default.d/*.conf;

}

}

在include /usr/share/nginx/modules/*.conf下设置负载均衡配置

验证负载均衡，访问http://10.1.1.115/ibp成功

三．分析

在服务器端抓包并下载

tcpdump -i ens835f3 dst port 80 -w capture.pcap

在本地工具打开可以看到访问目的地址是dmx.xx.ha.yc，源页面访问地址是http://10.1.1.115/ibp，因此也可以证明反向代理成功。
