nginx 多个vs,一台服务器多个server监听不同端口，都从80访问

案例
1、一台服务器上两个python一个监听5001，一个监听6001。
2、都想通过域名:80端口访问。那么只能使用nginx的多个vs了。两个域名 wiki.xxx.com; www.xxxx.com

粗略配置如下：

upstream flask5001 {
server 127.0.0.1:5001 weight=1 max_fails=0;
}
upstream flask6001 {
server 127.0.0.1:6001 weight=1 max_fails=0;
}
server {
listen 80;
server_name wiki.xxx.com;
root /data/webapps/sc;
location / {
access_log logs/static.log main;
error_log logs/static.error.log notice;

if ( !-f $request_filename ) {
proxy_pass http://flask5001; break;
}
}
}
server {
listen 80;
server_name www.xxxx.com;
root /data/webapps/Content;
location / {
access_log logs/static3.log main;
error_log logs/static3.error.log notice;

if ( !-f $request_filename ) {
proxy_pass http://flask6001; break;
}
}
}
注意proxy的配置
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 20m;
client_body_buffer_size 256k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 128k;
proxy_buffers 4 64k;
proxy_busy_buffers_size 128k;
proxy_temp_file_write_size 128k;
