nginx 转发ftp请求

nginx1.9之后直接使用Stream配置就可以了，当然需要先安装stream模块

1.nginx 增加tcp

./configure --with-stream --with-pcre=../pcre-8.38
./configure --with-stream --without-http_rewrite_module

2.配置nginx.conf

http {
    ……
}

stream {    
    upstream sftp{
        hash $remote_addr consistent; 
        server 172.0.0.1:22 max_fails=3 fail_timeout=30s; 
    }
    server {
        listen 8080;
        proxy_connect_timeout 1s; 
        proxy_timeout 30s; 
        proxy_pass sftp;
    }
}
