Automate the upgrade of Atlassian Stash on Linux

Upgrading existing software is sometimes cumbersome. Long checklists, validating pre-conditions, maintaining backups etc.

So is it with Atlassian Stash. Stash is an awesome software to manage your Git repositories. As Atlassian delivers often new releases it became tedious for me to upgrade our Stash installation.

I wrote a small bash script that now automates the process for me. The script does the following:

• Read the Stash version number and download URL from a prompt
• Downloads and unpacks the new version
• stops Stash
• deletes a previous existing backup folder
• moves the current program directory to a backup location
• creates a new program directory copies the new version into it
• makes sure that file and folder permissions are set correctly
• checks if the needed SQL library is in place
• copies the previous server config file
• set the environment
• starts Stash

I’ve posted the script below. Check if you need to modify it for your own installation. There is no error handling (which probably should be in there). But hey, it worked several times. ;-)

[code lang=“bash”] #!/bin/bash # # This script updates Atlassian Stash on Linux # # Change the following parameters according if needed

# This parameter defines the download root folder for the new version DLLOCATION=/tmp/download/atlassian/stash # This parameter defines the root program folder (assuming that “stash” is the main program folder) ATLASSIAN_ROOT_DIR=/opt/atlassian/ # This parameter defines the data folder of Stash ATLASSIAN_STASH_DATA=/var/atlassian/application-data/stash
