DD-WRT Forum :: View topic - Backup settings and restore them to even different hardware.
DD-WRT Forum :: View topic - Backup settings and restore them to even different hardware.
Very usefull
When DD-WRT does a backup of the settings this is done in a binary way. Even if no variables have changed and the hardware has not changed, it is not totally safe to restore this binary backup on another version.
I'm saving these variables to a script. This was not my idea, but the other implementation on this forum was saving more than it should.
This script also creates some variables that don't really exist. I previously wrote a script that was able to avoid this, but it had a terrible speed-impact. The variables it creates (makes up) comes from data containing a "=". This really is not a problem.
I'm deliberately skipping some variables that contain hardware-specific data. This way it is safe to restore these settings on different hardware.
After an upgrade you can run this restore-script and be up and running in no time.
Code:
#!/bin/sh
#
# This shell script creates a shell file with lines of the form
# nvram set x="y"
# for every nvram variable found from
# nvram show

Installing FreePBX 12 on CentOS 6.5 - How to Get Started - Documentation
Installing FreePBX 12 on CentOS 6.5 - How to Get Started - Documentation
Install Centos 6.5
Initial System Setup
Disable selinux
In /etc/sysconfig/selinux , change the following lines:
reboot, and verify the selinux status by running 'sestatus'. It should say:
Update Your System
Install Additional Required Dependencies
Add Asterisk/Digium CentOS Repos
IPTables
You must disable the default iptables. You can re-enable it later, once you have made the appropriate changes. Information on iptables can be found with a quick Google search. If iptables is left running, it will (at very least) block you from accessing the web interface.
See the current status:
Disable iptables:
Stop the service (this skips rebooting again):
Auto Start MySQL
You must have mysql running for freepbx to operate normally. You need to set it to start at boot time. with the following command:
Then start mysqld if you don't plan on rebooting during the installation phase:
Auto Start Apache
You will want Apache running, so you can access the FreePBX admin interface, You need to set it to start at boot time. with the following command:
Then start apache if you don't plan on rebooting during the installation phase:
Install PearDB
Reboot server
Install Dependencies for Google Voice (If needed/wanted)
Install iksemel
Add the Asterisk User
Install and Configure Asterisk
Install DAHDI.
Install Asterisk
Install Asterisk-Extra-Sounds
Install and Configure FreePBX
Download and extract FreePBX.
Set ownership permissions.
A few small modifications to Apache.
Configure Asterisk database in MYSQL.
Set permissions on MYSQL database.
Restart Asterisk and install FreePBX.
Finally, one last mod and start FreePBX.
Start FreePBX
Navigate:
http://yourlocalipaddress/html or if you prefer http://localhost/admin
Install and Setup Commercial Modules
Enable the FreePBX Commercial yum repos
yum clean all to clean out yum cache so it will find out new RPMs
yum install needed RPMs for Commercial Modules
Restart Apache and Install Sysadmin
For Further information see: CentOS and RHEL based systems.
