How to upgrade zabbix 4.2 to 4.4 on Ubuntu and Debian

How to upgrade zabbix 4.2 to 4.4 on Ubuntu and Debian

Upgrade procedure

Step 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

Step  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).

Please follow this article to take mysql/mariadb backup.

Step  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/doc/zabbix-* /opt/zabbix-backup/

Step  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 9 run:

# wget https://repo.zabbix.com/zabbix/4.4/debian/pool/main/z/zabbix-release/zabbix-release_4.4-1+stretch_all.deb
# dpkg -i zabbix-release_4.4-1+stretch_all.deb

On Debian 8 run:

# wget https://repo.zabbix.com/zabbix/4.4/debian/pool/main/z/zabbix-release/zabbix-release_4.4-1+jessie_all.deb
# dpkg -i zabbix-release_4.4-1+jessie_all.deb

On Ubuntu 18.04 run:

# wget https://repo.zabbix.com/zabbix/4.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.4-1+bionic_all.deb
# dpkg -i zabbix-release_4.4-1+bionic_all.deb

On Ubuntu 16.04 run:

# wget https://repo.zabbix.com/zabbix/4.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.4-1+xenial_all.deb
# dpkg -i zabbix-release_4.4-1+xenial_all.deb

On Ubuntu 14.04 run:

# wget https://repo.zabbix.com/zabbix/4.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.4-1+trusty_all.deb
# dpkg -i zabbix-release_4.4-1+trusty_all.deb

Update the repository information.

# apt-get update

Step  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.

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

# apt-get install zabbix-apache-conf

Step  6. Review component configuration parameters

Step  7. Start Zabbix processes

Start the updated Zabbix components.

# service zabbix-server start
# service zabbix-proxy start
# service zabbix-agent start

Step  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 4.4.x (for example, from 4.4.1 to 4.4.3). 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.*'
