五分钟9步搞定nginx正向代理配置

nginx在绝大数的场景中我们使用其用于做web中间件或反向代理使用，但是nginx实际上也提供了正向代理的功能。下面我们来进行nginx正向代理配置操作，以便大家能够掌握nginx正向代理配置方法。

第一步：获取nginx正向代理模块

git clone 

https://github.com/chobits/ngx_http_proxy_connect_module

第二步：下载nginx源码包

wget http://nginx.org/download/nginx-1.9.12.tar.gz
tar xf nginx-1.9.12.tar.gz

第三步：通过补丁方法把上述下载的正向代理模块导入到nginx模块存储目录

cd nginx-1.9.12/
patch -p1 < 
/root/ngx_http_proxy_connect_module/patch/proxy_connect.patch

第四步：编译安装nginx

 yum -y install openssl-devel zlib-devel prce-devel
 ./configure 
 --add-dynamic-module=/root/ngx_http_proxy_connect_module
make && make install

第五步：配置所允许通过代理主机的主机列表

 cat /usr/local/nginx/conf/client-allow.conf
allow 127.0.0.1;
allow 192.168.216.1;
allow 192.168.216.185;

第六步：修改nginx配置文件

 cat /usr/local/nginx/conf/nginx.conf
user  nobody;
worker_processes  1;
error_log  logs/error.log;
error_log  logs/error.log  notice;
error_log  logs/error.log  info;
pid        logs/nginx.pid;

load_module /usr/local/nginx/modules/ngx_http_proxy_connect_module.so; #位置注意
events {
    worker_connections  1024;
}

http {
    include       mime.types;default_type  application/octet-stream;
    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;
    gzip  on;
    server {listen       8080; #代理端口resolver        119.29.29.29; #域名解析服务器proxy_connect;proxy_connect_allow     443 563;proxy_connect_connect_timeout   10s;proxy_connect_read_timeout      10s;proxy_connect_send_timeout      10s;
    location / {proxy_pass  http://$host;proxy_set_header Host $host;}include client-allow.conf; #主机白名单deny all; #除了主机白名单中的主机，拒绝所有
    error_page  404              /404.html;
    redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;location = /50x.html {root   html;}
    proxy the PHP scripts to Apache listening on 127.0.0.1:80
    location ~ \.php$ {proxy_pass   http://127.0.0.1;}
    pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    location ~ \.php$ {root           html;fastcgi_pass   127.0.0.1:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;include        fastcgi_params;}
    deny access to .htaccess files, if Apache's document rootconcurs with nginx's one
    location ~ /\.ht {deny  all;}}

    another virtual host using mix of IP-, name-, and port-based configuration
    server {
        listen       8000;listen       somename:8080;server_name  somename  alias  another.alias;
        location / {
            root   html;index  index.html index.htm;
        }
    }

    HTTPS server
    server {
        listen       443 ssl;server_name  localhost;
        ssl_certificate      cert.pem;ssl_certificate_key  cert.key;ssl_session_cache    shared:SSL:1m;ssl_session_timeout  5m;
        ssl_ciphers  HIGH:!aNULL:!MD5;ssl_prefer_server_ciphers  on;
        location / {root   html;index  index.html index.htm;}
    }
}

第七步：检查并启动nginx服务

/usr/local/nginx/sbin/nginx -t #检查配置文件

/usr/local/nginx/sbin/nginx # 启动服务

/usr/local/nginx/sbin/nginx -s stop #关闭

/usr/local/nginx/sbin/nginx -s reload #重启加载配置文件

ss -anput | grep ":8080" #检查端口

第八步：被代理主机配置

五分钟9步搞定nginx正向代理配置

第九步：被代理主机验证nginx正向代理可用性

ss -anput | grep ":8080"

tcp LISTEN 0 128 *:8080 *:* users:(("nginx",pid=19515,fd=6),("nginx",pid=19514,fd=6))

tcp ESTAB 0 0 192.168.216.184:8080 192.168.216.185:35718 users:(("nginx",pid=19515,fd=11))

tcp ESTAB 0 0 192.168.216.184:8080 192.168.216.185:35712 users:(("nginx",pid=19515,fd=3))
