503 Service Unavailable Error

The site loads perfectly. Thanks to All

Hi - how did you resolve the php error? I have several vhosts set up, and am using php 7.1 on several - the default php is far too old for a lot of things.

Anyway - run updates and rebooted. I have set my default php to php 7.1. The vhost is set to use the default, but I get an error saying it is using 5.6:

This version of Nextcloud requires at least PHP 5.6.0
You are currently running 5.4.16. Please update your PHP version.

If I set the vhost to use 7.1, get

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Checking the status:

Okay - creating the /var/run/php-fpm directory gets things working, but I need to set each vhost’s php version to 7.1, rather than setting the default version to 7.1 and setting the vhosts to default.

I seem to remember this caused problems with some php applications … but don’t recall exactly what.

stephdl · April 19, 2018, 1:26pm

Let me dive in it, something wrong it seems. I have had another similar case by email lastly

stephdl · April 19, 2018, 3:03pm

ok error found, you can blame me. A fix is coming…systemd is really awesome

Don_Robertson · April 20, 2018, 4:54am

Personally, I blame the scapegoats.

Don_Robertson · April 30, 2018, 5:01am

Well, back to where I was - but this time the directory exists.

From the apache log:

So now my nextcloud server is not running - the only php services that can run are ones that use php 5.4. ie, old ones.

Any help appreciated

Don

stephdl · April 30, 2018, 8:10pm

I believed that nextcloud uses php56 ?

mrmarkuz · April 30, 2018, 9:02pm

Nextcloud 12 used php56 AFAIK, the actual Nextcloud 13 uses php71, which is provided by nethserver-rh-php71-php-fpm.

Don_Robertson · April 30, 2018, 11:03pm

Nextcloud uses php 5.6 or greater. It used to work fine on 7.1, now does not work on 5.6 or 7.1.

Neither do other applications - the only applications that work are ones that work with php 5.4.

mrmarkuz · April 30, 2018, 11:22pm

OK, you seem to use Nextcloud in a vhost, I didn’t recognize that. I meant the Nethserver Nextcloud implementation used php56 in previous version and uses php71 now.

stephdl · May 1, 2018, 6:06am

Nevermind, the issue is there…

github.com

stephdl/nethserver-php-scl/blob/ns7/root/etc/e-smith/templates/httpd/vhost-extra/15PhpScl_values

{
use esmith::ConfigDB;
my $vdb = esmith::ConfigDB->open_ro('vhosts') || die("Can't open vhosts db");
my $db = esmith::ConfigDB->open_ro || die("Can't open config  db");

my $PhpVersion = $vdb->get_prop("$VhostName",'PhpVersion') || 'default';


if ($PhpVersion ne 'default')
    {
    # write the configuration
    $OUT .= "\n";
    $OUT .= "# use php-fpm with mod_proxy_fcgi by socket 
# from Remi repository  instead of the default PHP\n";
$OUT .= << "EOF";

upgrade pushed, please update and sorry for the inconvenience

Don_Robertson · May 1, 2018, 10:26pm

Okay - normal service has been resumed. I accidentally upgraded my Nextcloud manually (which indicates how much easier these things are nowdays and then had problems with the Nethserver Nextcloud package, so wound up removing that package and installing Nextcloud from the Nextcloud site.

One little thing - if I go to the ‘PHP Settings’ section, and set the default version of php to 7.1, then go to ‘Virtual Host’ -> vhost edit -> Php Software collection, and set it to ‘default’, the vhost does not use php 7.1 but the Nethserver default of 5.4.

Should it use the default version from the PHP settings page, or am I misunderstanding this?

Cheers,

Don

stephdl · May 2, 2018, 10:24am

Probably a translation issue, now when you set the php value for the server it is only on the folder /var/www/html because nethgui is not compatible with php71 and php70.

When you use the php default value for a vhost, it is php54 for el7, even if you use the php72 for /var/www/html.

I need to explicit this.

stephdl · May 2, 2018, 7:13pm

done and released

Don_Robertson · May 14, 2018, 4:44am

Hmm. I was sure I had set the default to 7.2 and the vhosts to default. Maybe not.

The old memory isn’t what it um thingie.

pagaille · June 4, 2019, 1:06pm

Hi there, hi @stephdl,

I just installed nethserver-php-scl and the same error appears on my system (for a vhost)

[proxy:error] [pid 1680] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /var/run/php73-php-fpm/www-php73.sock (*) failed

And indeed :

# cat /var/run/php73-php-fpm/www-php73.sock
cat: /var/run/php73-php-fpm/www-php73.sock: No such file or directory

But the folders exists

# ls -lai /var/run/
101 drwxr-xr-x  2 root   root     40 Jun  4 12:41 php56-php-fpm
 99 drwxr-xr-x  2 root   root     40 Jun  4 12:41 php70-php-fpm

137 drwxr-xr-x  2 root   root     40 Jun  4 12:46 php73-php-fpm

And the service is up and running :

stephdl · June 4, 2019, 2:07pm

Only for one vhost?

Which one?

When you change the php version could you catch something in log messages
