NethServer Version: NethServer release 7.4.1708
Module: PHP

In my vhost I am attempting run Drupal 7, the files and folders are owned by apache:apache

When I load my vhost by the domain name with any version of PHP other than the default version I get the follow errors

Hi @tzar,

I tried it without vhost and it worked, I didn’t have to install extra php packages…

yum install nethserver-php-scl nethserver-virtualhosts nethserver-postgresql
wget https://ftp.drupal.org/files/projects/drupal-7.56.tar.gz
tar -xf drupal-7.56.tar.gz
mv drupal-7.56 /var/www/html/drupal
chown -R apache:apache /var/www/html/drupal/
su postgres -c "createuser drupal"
su postgres -c "psql -c \"alter user drupal with encrypted password 'SECRET';\""
su postgres -c "createdb -O drupal -T template0 -EUTF8 drupal"

Browse to https://YOURNETHSERVER/drupal and finish installation.

I am moving an existing website to NethServer, the existing database is MSQL, so I installed mariadb10 from https://wiki.nethserver.org/doku.php?id=mariadb101

I moved the website to /var/www/html directory and now I am get the following error
[pid 15446] (111)Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1:9071 (*) failed
[proxy_fcgi:error] [pid 15446] [client 10.1.10.15:65109] AH01079: failed to make connection to backend: 127.0.0.1

#4

Do you mean Microsoft SQL Server?

How did you migrate the DB?

Nethserver uses mariadb 5 so no need for mariadb101 for drupal.

Maybe there are old configs including paths or other directives of your old server?

You may try

systemctl restart php71-php-fpm

and to show if the port is open:

netstat -tpln | grep 9071

#5

Before I created the vhost:

netstat -tpln | grep 9071
tcp        0      0 127.0.0.1:9071          0.0.0.0:*               LISTEN      14570/php-fpm: mast

when I create a vhost. I select PHP 7.1 and in the /var/log/messages I see the following error

esmith::event[16405]: Event: vhost-create FAILED

systemctl status php71-php-fpm

ERROR: unable to bind listening socket for address '/var/run/php-fpm/zest-php71.sock': No such file or directory (2)

Failed to start The PHP FastCGI Process Manager.

The old server was using mariadb 10, and php 7.1 there are no old paths in the database

#6

Does any one know how to get Drupal Clean URLs to work on NethServer? I have no issues loading the website from /var/www/html folder using php 7.1.

The site loads fine and pages are accessible using the full address ie. http://sub.example.com/index.php?q=admin/modules or http://sub.example.com/index.php?q=user/1 but I get the following error when I try to access http://sub.example.com/user

Not Found
The requested URL /user was not found on this server.
#7

You may create /etc/httpd/conf.d/drupal.conf with following content:

<directory /var/www/html>
AllowOverride All
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^ index.php [L]
</directory>

and restart httpd

systemctl restart httpd

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.

#11

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

#12

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

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

#15

I believed that nextcloud uses php56 ?

#16

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

#17

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.

#18

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.

#19

Nevermind, the issue is there…

upgrade pushed, please update and sorry for the inconvenience
