Nginx Agent Non-80 port settings and related parameter description _nginx



from:http://blog.csdn.net/luckykapok918/article/details/44461465

Nginx through 80-port reverse proxy to Tomcat implementation is very simple, through the JSP Request.getserverport () get to the port number is still 80, And if nginx using a non-80 port to do the Echo Agent Request.getserverport () get to the port number returned will still be 80, so the edge is not correct response.sendredirect

String path = Request.getcontextpath ();
String basepath = request.getscheme () + "://" +request.getservername () + ":" +request.getserverport () +path+ "/";

So Response.sendredirect will jump to port 80.

Solution:

Modify proxy.conf Get you write the agent's configuration into the Nginx, or you can modify it internally

Proxy_redirect off;

# nginx Non 80 port processing
Proxy_set_header Host $host: $server _port;
# Get real IP
Proxy_set_header X-real-ip $remote _addr;
# Get the real IP of the agent
Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;
Client_max_body_size 10m;
Client_body_buffer_size 128k;
Proxy_connect_timeout 90;
Proxy_send_timeout 90;
Proxy_read_timeout 90;
Proxy_buffer_size 4k;
Proxy_buffers 4 32k;
Proxy_busy_buffers_size 64k;
Proxy_temp_file_write_size 64k;

Nginx vhost Virtual Host agent configuration

Location ~* "\. (jsp|do) $ "{
Proxy_pass http://kinggoo.ts;

# Use include to introduce it.
Include proxy.conf;
}

Instance:

If the Nginx listening port is not the default 80 port, change to a different port such as 8181 port.

Request.getserverport () in the back-end server could not get the correct port, the return is still 80;

At Response.sendredirect (), the client may not be able to obtain the correct redirection URL.

The correct configuration method is

Add a port number after the $host, such as $host:8181

server {
Listen 8181;
server_name localhost;

Location/{
Proxy_pass http://147.16.24.175:9500;
Proxy_set_header Host $host: 8181;
Proxy_set_header X-real-ip $remote _addr;
Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;

}
}
