As follows:

server {
    listen       80;
    server_name  dev.drpb.com;
    root /Users/Stone/repo/oschina/drsoft/page-builder;
    location ~ \.php$ {
        fastcgi_index  index.php;
        fastcgi_pass  127.0.0.1:9000;
        include fastcgi.conf;
    }
}
server {
    listen       80;
    server_name  dev.drp.com;
    root /Users/Stone/repo/oschina/drsoft/site;
    location ~ \.php$ {
        fastcgi_index  index.php;
        fastcgi_pass  127.0.0.1:9000;
        include fastcgi.conf;
    }
}

There are two server configuration blocks in the nginx configuration, and they have a common php reverse proxy configuration part.

How to add:

location ~ \.php$ {
    fastcgi_index  index.php;
    fastcgi_pass  127.0.0.1:9000;
    include fastcgi.conf;
}

Extract it and put it in one place instead of writing it once in each server (I tried putting it in the http block of its common parent but it didn't work), thank you!
