Example: Configure and Refresh Scripts from the Primary Source Location
The following example configures a primary source file location for an op script on a device running Junos OS. The remote source is defined as an HTTP URL. The example uses the primary source to update the local copy of the script on the device.
Requirements
Device running Junos OS
Overview
You can store a single primary copy of each automation script in a central repository. You can then make changes to the primary script in one place and then update the local copy of the script on devices where the script is enabled.
This example enables the op script iso.xsl on a device running Junos OS and then configures a primary source location for the script. The remote source for the iso.xsl file is the HTTP URL http://my.example.com/pub/scripts/iso.xsl.
Once you configure the primary source location, you refresh the local script by issuing the
set refresh configuration mode command at the hierarchy level
where you configured the script. In this example, you would issue the set
refresh command at the [edit system scripts op file
iso.xsl] hierarchy level.
Configuration
Procedure
Step-by-Step Procedure
To download, enable, and configure the primary source location for the script:
Copy the script to the /var/db/scripts/op/ directory on the device.
In configuration mode, configure the
filestatement to enable the iso.xsl script.[edit system scripts op] user@R1# set file iso.xsl
To configure the primary source for the iso.xsl file, include the
sourcestatement and source location at the[edit system scripts op file iso.xsl]hierarchy level.[edit system scripts op file iso.xsl] user@R1# set source http://my.example.com/pub/scripts/iso.xsl
Issue the
commit and-quitcommand to commit the configuration and exit to operational mode.[edit] user@R1# commit and-quit
Results
system {
scripts {
op {
file iso.xsl {
source http://my.example.com/pub/scripts/iso.xsl;
}
}
}
}
Verifying the Script
Purpose
Verify that the script is on the device and enabled in the configuration.
Action
Issue the file list operational mode command
to view the files in the specified directory. The detail option provides additional information such as permissions, file
size, and modified date.
user@R1> file list /var/db/scripts/op detail /var/db/scripts/op: total 128 -rw-r--r-- 1 root admin 13897 Feb 10 2011 iso.xsl ...
Issue the show configuration system scripts op operational mode command to list the op scripts currently enabled
on the device.
user@R1> show configuration system scripts op file iso.xsl
Refreshing the Script from the Primary Source
Step-by-Step Procedure
To refresh the local copy of the script from the primary source file:
In configuration mode, issue the
set refreshcommand at the[edit system scripts op file iso.xsl]hierarchy level.[edit system scripts op file iso.xsl] user@R1# set refresh
Verification
Verifying the Updated Script
Purpose
After refreshing the script, verify that the local copy is updated.
Action
Issue the file list operational mode command
with the detail option to view the files in the specified
directory. Verify that the modified date reflects the refreshed version.
user@R1> file list /var/db/scripts/op detail /var/db/scripts/op: total 128 -rw-r--r-- 1 root admin 14128 May 26 2011 iso.xsl ...
