Nginx configure upstream reverse proxy

Http {... Upstream tomcats {server 192.168.106.176 weight=1; server 192.168.106.177 weight=1;} server {location / ops-coffee/ {proxy_pass http://tomcats; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme;}

If you don't pay attention, you may fall into the trap of adding proxy_pass bars without adding bars. Here's the difference between proxy_pass http://tomcats and proxy_pass http://tomcats/:

Although it is only one / difference, the result is very different. It is divided into the following two situations:

1. There is no uri (proxy_pass http://tomcats) in the destination address. At this point, in the new target url, the matching uri part remains unchanged and is what it used to be.

Location / ops-coffee/ {proxy_pass http://192.168.106.135:8181;}http://domain/ops-coffee/-- > http://192.168.106.135:8181/ops-coffee/http://domain/ops-coffee/action/abc-- > http://192.168.106.135:8181/ops-coffee/action/abc

two。 The destination address contains uri (proxy_pass http://tomcats/ url / is also uri), and the matching uri part of the new destination url will be modified to the uri in this parameter.

Location / ops-coffee/ {proxy_pass http://192.168.106.135:8181/;}http://domain/ops-coffee/-- > http://192.168.106.135:8181http://domain/ops-coffee/action/abc-- > http://192.168.106.135:8181/action/abc is all the content of this article "how to configure upstream reverse proxy for nginx".
