Setting Server Variables before Apache Loads

  • 772

We have CentOS with Apache running on it. Basically, I have a few variables in /etc/environment and they're passed through to our Apache configs using PassEnv. The issue is that because Apache is before /etc/environment the variables are not found.

Is there a similar kind of /etc/environment file that I can add my global environmental variables into that is executed before apache (httpd) or do I have to start editing runlevels?

Kind regards,

Steve

  1. Use "/etc/sysconfig/httpd" to set Apache environment.

  2. If these are variables which apply to each and every user on the system, then they should be added in /etc/enviornment - but IIRC this file is not explicitly parsed by the init scripts.

    So you'd need to add a line in /etc/rc.d/init.d/functions, e.g.

    # -*-Shell-script-*-
#
# functions     This file contains functions to be used by most or all
#               shell scripts in the /etc/init.d directory.
# 
# amended to set env vars

TEXTDOMAIN=initscripts

. /etc/environment

    However if you only want these vars to be available to the webserver, then they should be declared in /etc/sysconfig/httpd, e.g.

    # Configuration file for the httpd service.

export MYSQL_USER = mydbuser

    (might work without the explicit export).
