Q:

Error with php5-fpm

I just installed nginx along with php-fpm when I encountered a 403 error when trying to view one of my sites. When I checked the nginx error logs, I saw a few things like permission denied, but I also noticed this:
/var/run/php5-fpm.sock failed (2: no such file or directory)

But I installed php-fpm, why would it be looking to load php5-fpm? I'm stumped, any ideas?
Thanks.
EDIT: server block in default.conf
server {
listen   81 default_server;
server_name  _;

#charset koi8-r;

#access_log  logs/host.access.log  main;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location / {
    root   /usr/share/nginx/html;
    index  index.html index.htm;
}

error_page  404              /404.html;
location = /404.html {
    root   /usr/share/nginx/html;
}

# redirect server error pages to the static page /50x.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$ {
#    proxy_pass   http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
#    root           html;
#    fastcgi_pass   127.0.0.1:9000;
#    fastcgi_index  index.php;
#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#    include        fastcgi_params;
#}

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

}

A:

By default, most distributions configure php-fpm to listen to TCP socket on port 9000.
Make sure your fpm is actually configured to listen to a file socket
listen = /var/run/php5-fpm.sock
Or configure nginx to fcgi_pass 127.0.0.1:9000
