# Easy UniFi Controller Upgrade Script for Unix/Linux Systems
|
||
|
|
# by Steve Jenkins (stevejenkins.com)
|
||
|
|
# Version 2.3
|
||
|
|
# Last Updated January 8, 2017
|
||
|
|
|
||
|
|
# REQUIREMENTS
|
||
|
|
# 1) Assumes you already have any version of UniFi Controller installed
|
||
|
|
# and running on your system.
|
||
|
|
# 2) Assumes a user named "ubnt" owns the /opt/UniFi directory.
|
||
|
|
# 3) Requires a service start/stop script to properly shut down and
|
||
|
|
# restart the UniFi controller before and after upgrade. I've written
|
||
|
|
# compatible startup scrips for SysV and systemd systems at
|
||
|
|
# http://wp.me/p1iGgP-2wl
|
||
|
|
# 4) Requires wget command to fetch the software from UBNT's download site.
|
||
|
|
|
||
|
|
# USAGE
|
||
|
|
# Modify the "UNIFI_DOWNLOAD_URL" variable below using the full URL of
|
||
|
|
# the UniFi Controller zip file on UBNT's download site. Optionally modify
|
||
|
|
# any of the additional variables below (defaults should work fine),
|
||
|
|
# then run the script!
|
||
|
