15.1.7 Running custom scripts when a configurator is invoked
A configurator is responsible for reading the values in /etc/config/config.xml and making the appropriate changes live.
Some changes made by the configurators are part of the Linux configuration itself such as user passwords or ipconfig.
Currently there are nineteen configurators each one responsible for a specific group of config e.g. the "users" configurator
makes the user configurations in the config.xml file live. To see all the available configurators type the following from a
command line prompt:
# config
When a change is made using the Management Console web GUI the appropriate configurator is automatically run. This
can be problematic as if another user/administrator makes a change using the Management Console the configurator
could possibly overwrite any custom CLI/linux configurations you may have set.
The solution is to create a custom script that runs after each configurator has run. So after each configurator runs it will
check whether that appropriate custom script exists. You can then add any commands to the custom script and they will
be invoked after the configurator runs.
The custom scripts must be in the correct location:
/etc/config/scripts/config-postTo create an alerts custom script:
# cd /etc/config/scripts
# touch config-post-alerts
# vi config-post-alerts
This script could be used to recover a specific backup config or overwrite a config or make copies of config files etc.
15.1.8 Backing-up the configuration and restoring using a local USB stick
The /etc/scripts/backup-usb script been written to save and load custom configuration using a USB flash disk. Before
saving configuration locally, you must prepare the USB storage device for use. To do this, disconnect all USB storage
devices except for the storage device you wish to use.
Usage: /etc/scripts/backup-usb COMMAND [FILE]
COMMAND:
check-magic -- check volume label
set-magic -- set volume label
save [FILE] -- save configuration to USB
delete [FILE] -- delete a configuration tarbal from USB
list -- list available config backups on USB
load [FILE] -- load a specific config from USB
load-default -- load the default configuration
set-default [FILE] -- set which file becomes the default
The first thing to do is to check if the USB disk has a label:
# /etc/scripts/backup-usb check-magic
If this command returns "Magic volume not found", then run the following command:
# /etc/scripts/backup-usb set-magic
To save the configuration:
