Don't use yum update.

Run the scripts in order.

Do Apply Config at the end instead of after each update.

The FreePBX System Admin Pro module provides buttons that will do all the updates in order.

For simple updates, and after script updates, use the Module Admin module to upgrade all modules.

If you have removed the System Firewall module, the update scripts will reinstall it. You'll have to uninstall it again from Module Admin.

If you have installed the commercial EPM and disabled the firewall, you will want to remove these modules using Module Admin:

• OSS PBX End Point Manager
• Bulk Phone Restart
• Firewall

chkconfig iSymphonyServerV3 off

cat /etc/schmooze/pbx-version

or for older systems:

cat /etc/asterisk/freepbxdistro-version

This script will download and execute the next version of official FreePBX Distro update script in the series FreePBX-Distro-10.13.66. It does not do just module updates (other than when done by the official version update scripts). Use the GUI Module Admin module to update only the modules.

Run as root:

#!/bin/bash
ugdir=/root/upgradescripts
if [ ! -d $ugdir ]
then
 mkdir $ugdir
fi
version=`cat /etc/schmooze/pbx-version`
base=`echo $version | cut -f1 -d'-'`
build=`echo $version | cut -f2 -d'-'`
echo ""
echo ----------------------------------------
echo Current FreePBX version is $version
echo Checking for updates...
echo ----------------------------------------
echo ""
error=0
while [ $error = 0 ]
do
 build=`expr $build + 1`
 wget http://upgrades.freepbxdistro.org/stable/$base/upgrade-$base-$build.sh -O $ugdir/upgrade-$base-$build.sh
 error=$?
 if [ $error = 0 ]
 then
  chmod +x $ugdir/upgrade-$base-$build.sh
  $ugdir/upgrade-$base-$build.sh
 fi
done
echo ""
echo ----------------------------------------
echo Finished.
