1、nginx 從1.9.0版本開始支持四層代理,但做四層代理時 編譯需要添加 --with-stream模塊
# ./configure --prefix=/usr/local/nginx--user=www --group=www --with-http_ssl_module --with-http_stub_status_module --with-file-aio --with-stream
2、nginx配置文件
user www;
worker_processes 2;
events {
worker_connections 1024;
}
stream { #stram模塊 和http模塊是一同等級;做四層代理時需要添加上這個模塊;
server {
listen 30028; #30028端口將以4層TCP協議方式轉發至后端app_sever;
proxy_pass app_server;
}
upstream app_server{
server 172.22.0.44:30028;
server 172.22.0.45:30028;
}
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
