Patch Level Update

Patch Level Update#

This documentation explains how to perform a patch level update for Znuny 7.2.

Note

Your current system needs to be a Znuny 7.2.x where the x stands for the patch level. You can skip intermediate patch levels, e.g. update from 7.2.1 directly to 7.2.6

Prepare#

Stop all services to prevent any data from changing.

systemctl stop httpd
# Stop your local MTA, mostly Postfix, sometimes Exim or Sendmail
systemctl stop postfix
# Remove crontab, stop daemon
su -c 'bin/Cron.sh stop' - znuny
su -c 'bin/znuny.Daemon.pl stop' - znuny

systemctl stop apache2
# Stop your local MTA, mostly Postfix, sometimes Exim or Sendmail
systemctl stop postfix
# Remove crontab, stop daemon
su -c 'bin/Cron.sh stop' - znuny
su -c 'bin/znuny.Daemon.pl stop' - znuny

Backup#

Backup your system like you always do. The easiest way for small system is using the bundled backup script scripts/backup.pl.

Start Znuny#

Start all services again. We do not start the Znuny daemon manually, instead we wait for cron starting the daemon.

systemctl start httpd
# Start your local MTA, mostly Postfix, sometimes Exim or Sendmail
systemctl start postfix
# Create Znuny's crontab to start the daemon
su -c 'bin/Cron.sh start' - znuny

systemctl start apache2
# Start your local MTA, mostly Postfix, sometimes Exim or Sendmail
systemctl start postfix
# Create Znuny's crontab to start the daemon
su -c 'bin/Cron.sh start' - znuny
