FreePBX Installation

Add new user named 'asterisk' (it has tobe this way, please don't use adduser)

# useradd -s /bin/false -m asterisk

On /etc/apache2/envvars, look for this lines:

export APACHE_RUN_USER=www-data

export APACHE_RUN_GROUP=www-data

and change to below lines:

export APACHE_RUN_USER=asterisk

export APACHE_RUN_GROUP=asterisk

# mcedit /etc/apache2/envvars

On /etc/php5/apache2/php.ini, look for this line:

memory_limit = 16M

and change it to this line:

memory_limit = 100M

look for this line:

magic_quotes_gpc = On

and change it to this line:

magic_quotes_gpc = Off

# mcedit /etc/php5/apache2/php.ini

Run this just to make sure that this module (php5) already enabled

# a2enmod php5

Restart apache2, this step is very important for FreePBX installation

# /etc/init.d/apache2 restart

Apache2 running as user asterisk is a must! Check it with ps aux

# ps aux | grep apache

Change Asterisk's files and directories ownership to user asterisk

# chown asterisk:asterisk /etc/asterisk -R
# chown asterisk:asterisk /usr/lib/asterisk -R
# chown asterisk:asterisk /var/lib/asterisk -R
# chown asterisk:asterisk /var/log/asterisk -R
# chown asterisk:asterisk /var/spool/asterisk -R

astrundir => /var/run

and change it to:

astrundir => /var/log/asterisk

# mcedit /etc/asterisk/asterisk.conf

Run this just to make sure that asterisk is not currently running

# killall asterisk

Run Asterisk with specific parameters

# asterisk -U asterisk -G asterisk

It is very important for asterisk running as user asterisk and group asterisk

# ps aux | grep asterisk
