Shell Script from PHP not able to cp or mv or anything

Shell Programming and Scripting

Hi there,

For some reason my maintenance mode shell script is not working. Both shell scripts are chmod +x'd, and owned by apache, running from php using exec(), maintenance.html and htaccessmaintenance are both owned by apache.

My code is:

#/bin/bash

cp maintenance.html /var/www/vhosts/$1/httpdocs/maintenance.html
if [ -f /var/www/vhosts/$1/httpdocs/maintenance.html ]
then

wall 'copied'

fi

chown apache:psacln /var/www/vhosts/$1/httpdocs/maintenance.html
if [ -f /var/www/vhosts/$1/httpdocs/.htaccess ]
then
chown apache:psacln /var/www/vhosts/$1/httpdocs/.htaccess
mv /var/www/vhosts/$1/httpdocs/.htaccess /var/www/vhosts/$1/httpdocs/.htaccess.bak
chown apache:psacln /var/www/vhosts/$1/httpdocs/.htaccess.bak
fi
cp htaccessmaintenance /var/www/vhosts/$1/httpdocs/.htaccess
chown apache:psacln /var/www/vhosts/$1/httpdocs/.htaccess

It works executed from the command line, but not from PHP, no idea why. I know a lot of the chown's are overkill, but I'm grasping at straws now.

What is the PATH variable when seen inside PHP? That is probably the issue.
Add (example):

export PATH=/usr/bin:/usr/local/bin

as the first line of the script. Or. You can also source /etc/profile and .profile
This is probably a better solution.

It also depends who those directories belong to. If they're not writable by the apache group, apache and things apache runs probably can't touch them.
