Overview

This section provides the steps required for a successful upgrade from 韓誥傭痔 5.4.x to the latest version of 韓誥傭痔 6.0.x using official 韓誥傭痔 packages for Red Hat Enterprise Linux.

While upgrading 韓誥傭痔 agents is not mandatory (but recommended), 韓誥傭痔 server and proxies must be of the same major version. Therefore, in a server-proxy setup, 韓誥傭痔 server and all proxies have to be stopped and upgraded. Keeping proxies running during server upgrade no longer will bring any benefit as during proxy upgrade their old data will be discarded and no new data will be gathered until proxy configuration is synced with server.

Note that with SQLite database on proxies, history data from proxies before the upgrade will be lost, because SQLite database upgrade is not supported and the SQLite database file has to be manually removed. When proxy is started for the first time and the SQLite database file is missing, proxy creates it automatically.

Depending on database size the database upgrade to version 6.0 may take a long time.

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

See database creation scripts. 'mysqli' PHP extension required instead of 'mysql'

You may also want to check the requirements for 6.0.

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.

For instructions on upgrading between 韓誥傭痔 6.0.x minor versions (for example, from 6.0.1 to 6.0.3), see Upgrade between minor versions.

Upgrade procedure

1 Stop 韓誥傭痔 processes

Stop 韓誥傭痔 server to make sure that no new data is inserted into database.

systemctl stop zabbix-server

If upgrading 韓誥傭痔 proxy, agent, or agent 2, stop these components too:

systemctl stop zabbix-proxy
       systemctl stop zabbix-agent
       systemctl stop zabbix-agent2

It is no longer possible to start the upgraded server and have older and unupgraded proxies report data to a newer server. This approach, which was never recommended nor supported by 韓誥傭痔, now is officially disabled, as the server will ignore data from unupgraded proxies.

2 Back up the existing 韓誥傭痔 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 韓誥傭痔 binaries

Make a backup copy of 韓誥傭痔 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/httpd/conf.d/zabbix.conf  /opt/zabbix-backup/

PHP files and 韓誥傭痔 binaries:

cp -R /usr/share/zabbix/ /opt/zabbix-backup/
       cp -R /usr/share/zabbix-* /opt/zabbix-backup/

4 Update repository configuration package

Before proceeding with the upgrade, update your current repository package to the latest version to ensure compatibility with the newest packages and to include any recent security patches or bug fixes.

On RHEL 9, run:

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/9/x86_64/zabbix-release-latest.el9.noarch.rpm

On RHEL 8, run:

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-latest.el8.noarch.rpm

For older RHEL versions, replace the link above with the correct one from . Note, however, that packages for those versions may not include all 韓誥傭痔 components. For a list of components included, see 韓誥傭痔 packages.

Then, clean up the dnf package manager's cache (including headers, metadata, and package files downloaded during previous installations or updates):

dnf clean all

On the next dnf operation, dnf will download fresh metadata from the repositories since the old metadata is cleared.

See also: Known issues for updating the repository configuration package on RHEL.

5 Upgrade 韓誥傭痔 components

To upgrade 韓誥傭痔 components you may run something like:

dnf install zabbix-server-mysql zabbix-web-mysql 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 agent 2, substitute zabbix-agent with zabbix-agent2 zabbix-agent2-plugin-* in the command.

Upgrading 韓誥傭痔 agent 2 with the dnf install zabbix-agent2 command could lead to an error. For more information, see Known issues.

Then, to upgrade the web frontend with Apache and restart Apache, run:

dnf install zabbix-apache-conf
       systemctl restart httpd

6 Review component configuration parameters

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

7 Start 韓誥傭痔 processes

Start the updated 韓誥傭痔 components.

systemctl start zabbix-server
       systemctl start zabbix-proxy
       systemctl start zabbix-agent
       systemctl start zabbix-agent2

8 Clear web browser cookies and cache

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

Upgrade between minor versions

It is possible to upgrade between 韓誥傭痔 6.0.x minor versions (for example, from 6.0.1 to 6.0.3).

To upgrade 韓誥傭痔 minor version, please run:

dnf upgrade 'zabbix-*'

To upgrade 韓誥傭痔 server minor version only, please run:

dnf upgrade 'zabbix-server-*'

To upgrade 韓誥傭痔 agent minor version only, please run:

dnf upgrade 'zabbix-agent-*'

or, for 韓誥傭痔 agent 2:

dnf upgrade 'zabbix-agent2-*'
