connect() to unix:/tmp/php-fpm.sock failed (2: No such file or directory)

On my vagrant box , centtos 7, i had installed php7.0.3 and nginx 1.9.12. the php config www.conf. this file in the /usr/local/php/etc/php-fpm.d/ directory, Its configuration like this

user = www
group = www
;listen = /tmp/php-fpm.sock
listen = 127.0.0.1:9000
listen.owner = www
listen.group = www

and the nginx config. the file vm.demo.com.conf in the /usr/local/nginx/conf/vhost/ directory. Its configuration like this

server {
    listen       80;
    server_name vm.demo.com;
    index index.html index.htm index.php;
    root  /data/wwwroot/demo;

    location / {
        if (-f $request_filename/index.html){
            rewrite (.*) $1/index.html break;
        }
        if (-f $request_filename/index.php){
            rewrite (.*) $1/index.php;
        }
        if (!-f $request_filename){
            rewrite (.*) /index.php;
        }
    }
    location ~ .*\.(php|php5)?$ {
        #fastcgi_pass unix:/tmp/php-fpm.sock;
        fastcgi_pass 127.0.0.1:9000;

        fastcgi_index index.php;
        include fastcgi.conf;
    }
    access_log  logs/demo.log main;
}

in the nginx conf, if i use fastcgi_pass 127.0.0.1:9000 and the php-fpm.conf listen 127.0.0.1:9000, They are working properly bug if i use the socket configuration:

php www.conf 

user = www
group = www
listen = /tmp/php-fpm.sock
listen.owner = www
listen.group = www

nginx vm.demo.com.conf 

    location ~ .*\.(php|php5)?$ {
        fastcgi_pass unix:/tmp/php-fpm.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
    }

the nginx show 502 Bad gateway. in the nginx error.log show this.

Basically, the problem arises with ONE process (php-fpm) setting up the sock in the /tmp path, but it would not be visible by ANOTHER process (nginx).

There is a setting in the service config, which would block files created by different process, even though using the same user.

Find your service config file (ex: /etc/systemd/system/myapp.service) and then on add this setting: PrivateTmp=No to both your services (php and nginx).

[Service]
...
PrivateTmp=No

I had this problem, you can do this:

chmod 777 yourpath/php-fpm.sock

This worked for me.

For all those who use Homestead inside Vagrant:

I solved simply reloading vagrant with provision flag: from project root:

cd Homestead

and then:

vagrant reload --provision

in this manner recompile all configurations

You need to change the listen.owner and the listen.group

listen.owner = nginx

listen.group = nginx

In my case in this file: /etc/php-fpm.d/www.conf

The socket must be the same in you nginx block (like vhost in apache). I also moved the socket under /var/sockets

You could try changing user in /usr/local/php/etc/php-fpm.d/www.conf to nginx and restart service.

user = nginx
group = nginx
listen = /tmp/php-fpm.sock

I have met the same problem. And I just change the socket path to another directory but '/tmp', Then everything goes OK.

I have found a config (php5) that continues to use the unix socket and does not involve editing any other config files (except the nginx default site file).

location ~ \.php$ {
fastcgi_pass unix:/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
# \Add following to use sqlite as db.
fastcgi_param DB_CONNECTION sqlite;

}

Note:- the unix socket is not at /run/php/ (though it is for php7). The include fastcgi_params; is required to prevent the php file downloading instead of being interpreted.

For completeness the following is my entire default file.

index index.php index.html index.htm;

server {
  listen 80;
  server_name sponk.co.uk;

  rewrite_log on;

  root /vagrant/public_html;
  try_files $uri $uri/ /index.php$is_args$args;

  location ~ \.php$ {
    fastcgi_pass unix:/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
  }

  location ~ /\.ht {
     deny all;
  }

}
