php5-fpm.sock not found / created in /var/run - php

Question

I fail to connect to php5-fpm.sock. I have tried many solutions but still getting this error:
2017/11/20 11:17:21 [crit] 9670#9670: *1 connect() to unix:/var/run/php5-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 192.168.224.8, server: babylon, request: "GET /webmail/ HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "babylon"
My configuration is like this:
location /webmail {
alias /srv/roundcubemail;
index index.php index.html;
# Favicon
location ~ ^/webmail/favicon.ico$ {
root /srv/roundcubemail/skins/classic/images;

}
# Robots file
location ~ ^/webmail/robots.txt {

}
# Deny Protected directories

}

}
#Roundcube fastcgi config
location ~ /webmail(/.*\.php)$ {
error_log /var/log/nginx/x.log error;
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^/webmail/(.+\.php)(/.*)$;
fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME /srv/roundcubemail/$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME /srv/roundcubemail/index.php;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
Is it maybe a problem with permissions over directories? I don't think so.
The attempts that I made were:
I change the listen of my www.conf, for socket and IP but still not working
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user = www-data
group = www-data
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /var/run/php5-fpm.sock
;listen = 127.0.0.1:9000
; Set listen(2) backlog.
; Default Value: 65535 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 65535
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0660
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
I have restarted php5-fm and nginx and still nothing.
Any ideas how I can fix that?

Answer 1

First, ensure that php-fpm is installed, you could use this to check the current version if any:
php-fpm -v
Second check the php-fpm.conf configuration, and search for this line:
listen = /tmp/php-fpm.socket
In case it doesn't exist just add it, it can be also something like:
listen = /var/run/php5-fpm.sock
In some Linux distros normally this is used:
listen = /var/run/php5-fpm.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
In case you want to use a TCP socket:
Listen 127.0.0.1:9000
Restart php-fpm and check that the socket has been created in case of using a Unix domain socket, this can be done by doing this:
$ file /var/run/php5-fpm.sock
If socket exists if should print out something like this:
/var/run/php5-fpm.sock: socket

Answer 2

Could you please ensure those settings on your PHP-fpm/www.conf file
.....
user = www-data
group = www-data
listen.owner = www-data
listen.group = www-data
......
Then Restart PHP-fpm under root user.

Answer 3

listen.owner = nginx
listen.group = nginx
