NGINX 做TCP转发（端口转发）并记录日志

nginx安装 略 （注意：必须加上--with-stream这个模块）

修改nginx.conf：

user  www www;
worker_processes  4; 
pid        logs/nginx.pid;
 
events {
    #use epoll;                            #Linux最常用支持大并发的事件触发机制
    worker_connections  65535;
}
 
stream {
    log_format proxy '$remote_addr [$time_local] '
                 '$protocol $status $bytes_sent $bytes_received '
                 '$session_time "$upstream_addr" '
                 '"$upstream_bytes_sent" "$upstream_bytes_received" "$upstream_connect_time"';
 
    access_log logs/access_8000.log proxy ;
    open_log_file_cache off;
    
    upstream zifangsky {
        #hash $remote_addr consistent;
        server 10.10.100.31:8000 weight=5 max_fails=1 fail_timeout=20s;
    }
 
    server {
        listen 8000;
        proxy_connect_timeout 10s;
        proxy_timeout 10s;
        proxy_pass zifangsky;
    tcp_nodelay on;
    }
}

在上面的配置文件中配置了在访问此服务器的8080端口时，会将流量相应转发到10.10.100.31这个服务器的8000端口上。另外，测试发现只有当一个会话结束之后nginx才会将相关日志记录到指定的日志文件中
