nginx 配置两个域名指向服务器不同的路径的问题

如下配置，我有两个域名，分别想指向 /usr/local/nginx/html 和 /usr/local/nginx/html2 这两个不同的目录，但是现在在浏览器里输入这两个域名都是显示同一个目录里的代码文件，是什么原因？

server {
listen 80;
server_name testA.com;
location ~ \.php/?.*$ {
root html2;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
set $fastcgi_script_name2 $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+\.php)(/.+)$") {
set $fastcgi_script_name2 $1;
set $path_info $2;
}
fastcgi_param PATH_INFO $path_info;
fastcgi_param SCRIPT_FILENAME /user/local/nginx/html2$fastcgi_script_name2;
fastcgi_param SCRIPT_NAME $fastcgi_script_name2;
}
}

server {
listen 80;
server_name testB.com;
location ~ \.php/?.*$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
set $fastcgi_script_name2 $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+\.php)(/.+)$") {
set $fastcgi_script_name2 $1;
set $path_info $2;
}
fastcgi_param PATH_INFO $path_info;
fastcgi_param SCRIPT_FILENAME /user/local/nginx/html$fastcgi_script_name2;
fastcgi_param SCRIPT_NAME $fastcgi_script_name2;
}
}
