将某些域重定向到nginx中失败的不同文件夹

Question

我有三个子域名，如m.xyz.com，test.xyz.com，prod.xyz.com，main.xyz.com，如果我重定向我的子域，那么它会自动找到该网站的默认文件夹路径。我想将所有子域重定向到不同的文件夹位置。我在centos中使用nginx服务器，即使创建了四个单独的.conf文件，它也会重定向到默认位置。 .conf文件代码如下： -

服务器{

listen       80;
server_name  m.xyz.com www.m.xyz.com;

root   /usr/share/nginx/html/folder1/location1/;
index index.php index.html index.htm;

location / {
    #try_files $uri $uri/ =404;
    try_files $uri $uri.html $uri/ @extensionless-php;
    index index.html index.htm index.php;
}
# redirect server error pages to the static page /50x.html
#
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
    root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
location ~ \.php$ {
    try_files $uri =404;
    #fastcgi_pass unix:/var/run/xyz/xyz-php-fpm.sock;
    fastcgi_pass 192.168.1.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}
# rewrites
location @extensionless-php {
       rewrite ^(.*)$ $1.php last;
}
charset utf-8;
#access_log  /var/log/nginx/log/host.access.log  main;

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
#    deny  all;
#}

} `
