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;
}
}
