1. Agent introduction

1. Agent

The object of the forward proxy is the client

The object of the reverse proxy proxy is the server

Syntax

Syntax:    proxy_pass URL;
Default:    —
Context:    location, if in location, limit_except

Copy after login

1. http：

   http: //localhost:8000/uri/

2. https：

   https://192.168.1.111:8000/uri/

3. socket:

   http://unix:/tmp/backend.socket:/uri/

1. Create the real service configuration to be accessed: vim conf.d/real_server.conf

server {
    # 监听8080端口
    listen 8080;

    location / {
        # 配置访问根目录为 /vagrant/proxy
        root /vagrant/proxy;
    }
}

Copy after login

2. Create the reverse proxy configuration vim conf.d/fx_proxy.conf

server {
    # 监听80端口
    listen 80;
    server_name localhost;

    location ~ /fx_proxy.html {
        # 设置反向代理，将访问 /fx_proxy.html 的请求转发到 http://127.0.0.1:8080
        proxy_pass http://127.0.0.1:8080;
    }
}

Copy after login

3. nginx -s reload Reload nginx configuration file

4. Create /vagrant/proxy/fx_proxy.html file

• vim /vagrant/proxy/fx_proxy.html

nbsp;html>

    
        <meta>
        <title>反向代理</title>
    
    
        <h1>反向代理</h1>
    

5. Use ss -tln to check whether port 80 and port 8080 are all open

[root~]# ss -tln
State       Recv-Q Send-Q Local Address:Port               Peer Address:Port
LISTEN      0      128               *:8080                          *:*
LISTEN      0      128               *:80                            *:*
LISTEN      0      128               *:22                            *:*
LISTEN      0      10        127.0.0.1:25                            *:*
LISTEN      0      128              :::22                           :::*

Copy after login

6. Use curl for access testing

• http://127.0.0.1/fx_proxy.htmlcan be accessed normally

[root~]# curl http://127.0.0.1/fx_proxy.html
nbsp;html>

        
                <meta>
                <title>反向代理</title>
        
        
                <h1>反向代理</h1>
        

• http://127.0.0.1:8080/fx_proxy.htmlcan be accessed normally

[root~]# curl http://127.0.0.1:8080/fx_proxy.html
nbsp;html>

        
                <meta>
                <title>反向代理</title>
        
        
                <h1>反向代理</h1>
        

server {
    # 监听80端口
    listen 80;
    # 域名为 zx_proxy.ws65535.top;
    server_name  zx_proxy.ws65535.top;

    location / {
        # $http_x_forwarded_for 可以记录客户端及所有中间代理的IP
        # 判断客户端IP地址是否是 39.106.178.166，不是则返回403
        if ($http_x_forwarded_for !~* "^39\.106\.178\.166") {
            return 403;
        }
        root   /usr/share/nginx/html;
        index  index.html;
    }
}

server {
    # 代理服务监听的端口（注意，一定要看服务器供应商控制台的安全组是否开启了该端口）
    listen 3389;

    # 配置DNS，223.5.5.5是阿里云的DNS
    resolver 223.5.5.5;
    
    # 正向代理配置
    location / {
        proxy_pass http://$http_host$request_uri;
    }
}
