[英]How to redirect to specific upstream servers based on request URL in Nginx?
I'm using Nginx as a load balancer for my 5 app servers. 我正在使用Nginx作为我的5个app服务器的负载均衡器。
I'd like to redirect to specific servers based on the request URL, for instance: 我想根据请求URL重定向到特定服务器,例如:
acme.com/category/* => Server #1
acme.com/admin/* => Server #2
api.acme.com => Server #3
Fallback for any other URL => Server #4, #5
My config looks like: 我的配置看起来像:
upstream backend {
least_conn;
server 10.128.1.1;
server 10.128.1.2;
server 10.128.1.3;
server 10.128.1.4;
server 10.128.1.5;
}
server {
listen 80;
server_name _;
location / {
proxy_set_header Host $host;
proxy_pass http://backend;
}
}
I have no idea how to do this, since I'm not very familiar with Nginx - any one has some clues? 我不知道怎么做,因为我对Nginx不太熟悉 - 任何人都有一些线索?
Read the documentation , eveything is well explained in it. 阅读文档 ,eveything在其中得到了很好的解释。 There's particularly a beginner's guide explaining basics. 特别是初学者指南解释基础知识。 You would end up with : 你会最终得到:
upstream backend {
least_conn;
server 10.128.1.4;
server 10.128.1.5;
}
server {
server_name _;
location / {
proxy_set_header Host $host;
proxy_pass http://backend;
}
}
server {
server_name acme.com;
location /admin/ {
proxy_set_header Host $host;
proxy_pass http://10.128.1.2;
}
location /category/ {
proxy_set_header Host $host;
proxy_pass http://10.128.1.1;
}
location / {
proxy_set_header Host $host;
proxy_pass http://backend;
}
}
server {
server_name api.acme.com;
location / {
proxy_set_header Host $host;
proxy_pass http://10.128.1.3;
}
}
You will also need to rewrite the URL otherwise /whatever/ will get forwarded to the backend server 您还需要重写URL,否则/将转发到后端服务器
location /admin/ {
rewrite ^/admin^/ /$1 break;
proxy_pass http://10.128.1.2;
}
