PHP-FPM Problem with PHP-FPM multiple pool

Hi, I've been using Centminmod for my production server for a month now.
It's been running flawlessly. All the tutorials are great in directing me what to do.
I'm a beginner btw =)

---

Currently my server is running PHP-FPM on port 9000 (default settings) and everything's working fine.
The server is going to host like 8 vhosts. And I wanted to create a separated pool for some of my vhosts.

So I'm trying to add a new pool using UNIX socket. But I got no luck.
I keep geeting

[error] 28271#0: *5 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, ...

here's my setup:

in conf/php-blogs.conf (copied from php.conf because it's working fine for the default pools)

Code:

location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    #fastcgi_pass   127.0.0.1:9001;
    fastcgi_pass   unix:/tmp/phpfpm_blogs.sock;
    fastcgi_index  index.php;
    #fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  SCRIPT_FILENAME    $request_filename;
...
}

in conf/phpfpmd/pool_blogs.conf (copied from phpmyadmin, also because it works just fine)

Code:

[blogs]
user = blogs
group = nginx

;listen = 127.0.0.1:9001
listen = /tmp/phpfpm_blogs.sock
listen.allowed_clients = 127.0.0.1
listen.owner=blogs
listen.group=nginx

pm = ondemand
pm.max_children = 5
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 1
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.max_requests = 1000

pm.process_idle_timeout = 1800s;

rlimit_files = 65536
rlimit_core = 0

;request_terminate_timeout = 0
;request_slowlog_timeout = 0
slowlog = /var/log/php-fpm/blogs-slow.log

security.limit_extensions = .php .php3 .php4 .php5

;php_admin_value[open_basedir] = /usr/local/nginx/html/1234_mysqladmin1234:/tmp
php_flag[display_errors] = off
php_admin_value[error_log] = /var/log/php-fpm/blogs-error.log
php_admin_flag[log_errors] = on
php_admin_value[memory_limit] = 128M
php_admin_value[max_execution_time] = 1800
php_admin_value[post_max_size] = 32M
php_admin_value[upload_max_filesize] = 32M

and in my vhost.conf

Code:

server {
  server_name domain.com www.domain.com;

  # limit_conn limit_per_ip 16;
  # ssi  on;

  access_log /home/nginx/domains/domain.com/log/access.log combined buffer=32k;
  error_log /home/nginx/domains/domain.com/log/error.log;

  root /home/nginx/domains/domain.com/public;

  location / {

  # block common exploits, sql injections etc
  include /usr/local/nginx/conf/block.conf;

  # Enable for vBulletin usage WITHOUT vbSEO installed
  try_files            $uri $uri/ /index.php;

  }

  include /usr/local/nginx/conf/staticfiles.conf;
  include /usr/local/nginx/conf/php_blogs.conf;
  include /usr/local/nginx/conf/drop.conf;
}

serving static contents work just fine.
but when i access any php file, i just keep getting that STDERR: "Primary script unknown"
and changin UNIX socket to port 9001 also gives me this error...

Where did I go wrong? =(

 

Thank you for that reference link =)
