没用过 nginx 菜鸟想问问：
假如我服务器运行2个 nodejs 程序，一个是 localhost:3000，另一个是 localhost:8080
我能不能把域名 a.com 指向 localhost:3000，把域名 b.com 指向 localhost:8080？
解决方案
server{ listen 80; server_name a.com; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:3000; proxy_redirect off; }}server{ listen 80; server_name b.com; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:8080; proxy_redirect off; }}
