Best way to make RHSCL PHP available globally
The way to import a software collection into your current shell (not launch a sub-shell) is to source the "enable" file.
For example for rh-php56 on a Redhat 7 machine...
source /opt/rh/rh-php56/enable
You can now run "php", or read manpages "man php" as normal.
that will add the appropriate environment variables to the current shells environment. Individual users can do this in there .bashrc files, allowing it to be available from SSH (non-interactive shells)
You can also copy (or symlink) the enable file into /etc/profile.d/ with a ".sh" suffix to automatically enable it for ALL users.
For example
ln -s /opt/rh/rh-php56/enable /etc/profile.d/rh-php56.sh
Becareful doing this if more than environment is needed (such as daemons?). Or if multiple versions of that software is present on a system (for backward compatibility with other software/services), as there may be interaction between versions. Also users may not want the 'latest' version, or become confused as to why the 'base' system (EG: /etc configs) does not effect the software collection version.

I have installed RHSCL 2 using the following url:
using the RedHat subscription manager.
I then ran
yum remove php*
followed byyum install rh-php56
Everything went smoothly except now PHP is not found anywhere. I then ran
find / -name php
and foundrh-php56
in the following directories:/var/opt/rh/rh-php56/lib/php /opt/rh/rh-php56/register.content/var/opt/rh/rh-php56/lib/php /opt/rh/rh-php56/root/usr/bin/php /opt/rh/rh-php56/root/usr/lib64/php /opt/rh/rh-php56/root/usr/share/php
What is the best way to get these binaries into
/usr/bin
or any other directory that is usually globally available for all users?Did I miss a step when installing the packages which is why it is not available globally? Or is this just what happens when using RHSCLs?
I have tested the binaries in those folders and they work when I run
php -v
so it is working fine.My first thought is to just
cp
into/bin
or/usr/bin
but maybe there is an official way to do what I am asking?edit
Cannot comment, no rep... from chapter 3 of the link I posted, it says that software collection packages must be run like so:
scl enable rh-php56 'php -v'
Which does work... however how do I get it to run for all users like
$ php -v
with no additional commands. I need the php binaries globally available so webservers can use it and ssh users with normal shells.-

anthony over 8 yearsSven... I read it myself.. and all it has is starting a sub-shell with the collection made available. It does NOT detail how to make a collection available BY default without the user needing to run a sub-shell. I will detail a proper solution below.

Stefan Lasiewski over 8 yearsSven, that would mean that every user and every daemon would need to run
scl enable rh-php56 command
, which is complicated. Enabling it globally via @antofthy's answer is much more elegant.

Darvanen almost 8 yearswhich instance of php.ini does this method invoke?

Darvanen almost 8 yearsAhhh... I was restarting httpd instead of the php-fpm service. Posting here in case anyone else gets stuck that way.

Stefan Lasiewski about 7 yearsIs this actually sufficient to enable a SCL package? access.redhat.com/solutions/527703 seems to create a bash script which does something like
source scl_source enable python33

anthony almost 7 yearsShould be sufficient. It basically sets the environment to use the specific version over the system version. But only within the sub-shell started.
