2 Debian/Ubuntu

Overview

This section provides the steps required for a successful upgrade from Zabbix 7.0.x to Zabbix 7.2.x using official Zabbix packages for Debian/Ubuntu.

Before the upgrade make sure to read the relevant upgrade notes!

You may also want to check the requirements for 7.2.

It may be handy to run two parallel SSH sessions during the upgrade, executing the upgrade steps in one and monitoring the server/proxy logs in another. For example, run tail -f zabbix_server.log or tail -f zabbix_proxy.log in the second SSH session showing you the latest log file entries and possible errors in real time. This can be critical for production instances.

Upgrade procedure

1 Stop Zabbix processes

Stop Zabbix server to make sure that no new data is inserted into database.

service zabbix-server stop

If upgrading Zabbix proxy, stop proxy too.

service zabbix-proxy stop
2 Back up the existing Zabbix database

This is a very important step. Make sure that you have a backup of your database. It will help if the upgrade procedure fails (lack of disk space, power off, any unexpected problem).

3 Back up configuration files, PHP files and Zabbix binaries

Make a backup copy of Zabbix binaries, configuration files and the PHP file directory.

Configuration files:

mkdir /opt/zabbix-backup/
       cp /etc/zabbix/zabbix_server.conf /opt/zabbix-backup/
       cp /etc/apache2/conf-enabled/zabbix.conf /opt/zabbix-backup/

PHP files and Zabbix binaries:

cp -R /usr/share/zabbix/ /opt/zabbix-backup/
       cp -R /usr/share/zabbix-* /opt/zabbix-backup/
4 Update repository configuration package

To proceed with the update your current repository package has to be uninstalled.

rm -Rf /etc/apt/sources.list.d/zabbix.list

Then install the new repository configuration package.

On Debian 12 run:

wget https://repo.zabbix.com/zabbix/7.1/debian/pool/main/z/zabbix-release/zabbix-release_7.1-1+debian12_all.deb

wget https://repo.zabbix.com/zabbix/7.1/ubuntu/pool/main/z/zabbix-release/zabbix-release_7.1-1+ubuntu24.04_all.deb
       dpkg -i zabbix-release_7.1-1+ubuntu24.04_all.deb

       dpkg -i zabbix-release_7.1-1+ubuntu22.04_all.deb

On Ubuntu 20.04 run:

wget https://repo.zabbix.com/zabbix/7.1/ubuntu/pool/main/z/zabbix-release/zabbix-release_7.1-1+ubuntu20.04_all.deb
       dpkg -i zabbix-release_7.1-1+ubuntu20.04_all.deb

On Ubuntu 18.04 run:

wget https://repo.zabbix.com/zabbix/7.1/ubuntu/pool/main/z/zabbix-release/zabbix-release_7.1-1+ubuntu18.04_all.deb
       dpkg -i zabbix-release_7.1-1+ubuntu18.04_all.deb

Update the repository information.

apt-get update
5 Upgrade Zabbix components

To upgrade Zabbix components you may run something like:

apt-get install --only-upgrade zabbix-server-mysql zabbix-frontend-php zabbix-agent

If using PostgreSQL, substitute mysql with pgsql in the command. If upgrading the proxy, substitute server with proxy in the command. If upgrading the Zabbix agent 2, substitute zabbix-agent with zabbix-agent2 in the command.

Upgrading Zabbix agent 2 with the apt install zabbix-agent2 command could lead to an error. For more information, see Known issues.

Then, to upgrade the web frontend with Apache correctly, also run:

apt-get install zabbix-apache-conf
6 Review component configuration parameters

Make sure to review Upgrade notes to check if any changes in the configuration parameters are required.

For new optional parameters, see the What's new page.

7 Start Zabbix processes

Start the updated Zabbix components.

service zabbix-server start
       service zabbix-proxy start
       service zabbix-agent start
       service zabbix-agent2 start
8 Clear web browser cookies and cache

After the upgrade you may need to clear web browser cookies and web browser cache for the Zabbix web interface to work properly.

Upgrade between minor versions

It is possible to upgrade minor versions of 7.2.x (for example, from 7.2.1 to 7.2.3). It is easy.

To upgrade Zabbix minor version please run:

sudo apt install --only-upgrade 'zabbix.*'

To upgrade Zabbix server minor version please run:

sudo apt install --only-upgrade 'zabbix-server.*'

To upgrade Zabbix agent minor version please run:

sudo apt install --only-upgrade 'zabbix-agent.*'

or, for Zabbix agent 2:

sudo apt install --only-upgrade 'zabbix-agent2.*'
