使用Nginx实现端口转发TCP代理的实现示例

nginx -V

yum install -y pcre* openssl*

apt-get install zlib1g-dev libpcre++-dev openssl

wget Http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz
tar -zxvf ngx_cache_purge-2.3.tar.gz -C /usr/local/src

wget http://nginx.org/download/nginx-1.9.9.tar.gz

tar -zxf nginx-1.9.9.tar.gz

cd nginx-1.9.9
./configure --prefix=/usr/local/nginx \
  --add-module=/usr/local/src/ngx_cache_purge-2.3 \
  --with-http_stub_status_module --with-stream
make && make install;

events {
  ...
}

stream {
    upstream ldap {
        hash $remote_addr consistent;
        server 192.168.1.8:389;
    }
    server {
        listen 1389;
        proxy_connect_timeout 5s;
        proxy_timeout 5s;
        proxy_pass ldap;
    }
}

http {
  ...
}

/usr/local/nginx/sbin/nginx

netstat -anput | grep nginx
