Hi,
I'm trying to add PHP 5.6,25 as an additional PHP Version in CEntos 7.1 and ISPConfig 3.1dev.
I followed the guide:
https://www.howtoforge.com/how-to-u...pm-and-fastcgi-with-ispconfig-3-centos-6.3-p3
but at the end i've some problems:
1) don't find some files for example cp /opt/php-5.6.25/etc/php-fpm.conf.default
2) the sistem don't Start: /etc/init.d/php-5.6.25-fpm start (as there isn't star comand)
now i've the php 7.0.7 and it not work with Magento so i trying to install additional PHP like 7.0.2 or 5.6.25

Can you hel me ?
thanks to all

Thank you,
now it work and i can se Php 7.0.11
but the problem installing Magento it's the same:

[ERROR] BadMethodCallException: Missing required argument $metadata of Magento\Framework\EntityManager\MetadataPool. in /var/www/clients/client1/web9/web/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:45

 

hi Till,
I solved the problem by itself.
it was enough to simply delete the cache of the various browsers.
Now the installed Magento (with the ISPConfig script) but I can not install the sample-data when i run the comand ./magento command ....:
The openssl extension is required for SSL / TLS protection but is not available. If you can not enable the openssl extension, you can disable this error, at your own risk, by setting the 'disable-tls' option to true. # 0 / var / www / clients / client1 / web9 / web / vendor / composer /composer/src/Composer/Factory.php(306): Composer \ Factory :: createRemoteFilesystem (Object (Composer \ IO \ BufferIO), Object (Composer \ Config))
# 1 /var/www/clients/client1/web9/web/vendor/composer/composer/src/Composer/Factory.php(532): Composer \ Factory-> createComposer (Object (Composer \ IO \ BufferIO), '/ var / www / client ... ', false)

 

i undestand that i need to install and activate OpenSSL
and afeter install magento composer.
But now i'he a PHp multi version under ISPConfig....
how i can istall and activate OpenSSL?
i tried under ssh (putty) on VPS centos but nothing...
