Nginx下配置多个web服务

http {
    include mime.types;
    default_type application/octet-stream;
    sendfile on;
    keepalive_timeout 65;
    #web工程1
    upstream nana {
        server localhost:18880;
    }
    #web工程2
    upstream nananana {
        server localhost:18881;
    }
server {
    listen 8888;
    server_name localhost;
    location / {
        root html;
        index index.html index.htm;
    }
    #web工程1
    location ^~/first-path/ {
        proxy_pass http://nana/;
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 5s;
    }
    #web工程2
    location /firstPath {
        proxy_pass http://nananana/first-path;
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 5s;
    }
}
