Permanently enable a SCL

Solution 1:

using scl enable actually opens a new shell inside your current one, which is quite unclean, especially if done from a login script.

You should place, instead, in your ~/.bash_profile:

source /opt/rh/rh-nginx18/enable


source scl_source enable rh-nginx18

The latter is more "elegant" as it is independent from the actual installation path.

This has the effect of loading the environment in your current shell.

Solution 2:

Redhat proposes placing a file in /etc/profile.d, i.e. for python:

$ cat /etc/profile.d/
source scl_source enable python33

As this works for the devtools under centos for me you could try this.
