apache2, nginx, iis反向代理简单配置

测试配置

• 后端网站地址192.168.1.100，运行在物理机
• 虚拟机server2008192.168.241.141
• 虚拟机ubuntu16192.168.241.132安装apache2和nginx

Apache2.4

配置环境为ubuntu 16.04 server

启用反向代理模块

sudo a2enmod proxy
# 如果没有该模块
# apt-get install libapache2-mod-proxy*
systemctl restart apache2

复制一份默认虚拟站点文件000-default.conf,添加以下内容

# ProxyPreserveHost On 填写原始的HOST到后端服务器
ProxyPreserveHost On
ProxyPass / http://192.168.1.100:5000/
ProxyPassReverse / http://192.168.1.100:5000/

nginx

修改default配置中location /

 location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                # try_files $uri $uri/ =404;
                proxy_pass  http://192.168.1.100:5000;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
        }

重启nginx

IIS

安装IIS模块URL Rewrite和Application Request Routing

• http://download.microsoft.com/download/E/9/8/E9849D6A-020E-47E4-9FD0-A023E99B54EB/requestRouter_amd64.msi
• http://download.microsoft.com/download/E/A/9/EA9F19BC-0EEB-49C9-B32D-56852BBE56DA/rewrite_amd64_zh-CN.msi

安装完毕后应该有如下图标

编辑默认站点重定向

图片中地址依据本次试验应填写192.168.1.100:5000

试验网站

192.168.1.100:5000

# coding=utf-8
#

from flask import Flask, request


app = Flask(__name__)


@app.route('/')
def index():
    s = ''
    for _ in request.headers:
        k, v = _
        s += '<p>%s: %s</p>' % (k, v)
    return '%s' % s


app.run(host='0.0.0.0')

不同代理服务器对应的消息头

apache2

nginx

IIS

总结

保留原始Host

# apache2
ProxyPreserveHost On
# nginx
proxy_set_header Host $http_host;

获取原始客户端访问ip
都可以从X-Forwarded-For中提取第一个ip值

Apache2 和IIS设置X-Real-IP值获取客户端ip可能需要额外配置，需要查询相关资料
