zabbix3.4升级到4.4
1 Stop Zabbix processes
Stop Zabbix server to make sure that no new data is inserted into database.
# systemctl stop zabbix-server
If upgrading the proxy, stop proxy too.
# systemctl stop zabbix-proxy
It is no longer possible to start the upgraded server and have older, yet unupgraded proxies report data to a newer server. This approach, which was never recommended nor supported by Zabbix, now is officially disabled when upgrading to 4.4 (or later) from any version before 4.4, as the server will ignore data from unupgraded proxies.
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/httpd/conf.d/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/
4 Update repository configuration package
To proceed with the upgrade your current repository package has to be updated.
# rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm(服务器可以连网的情况下)
5 Upgrade Zabbix components
To upgrade Zabbix components you may run something like:
# yum upgrade 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.
To upgrade the web frontend with Apache on RHEL 8 correctly, also run:
# yum install zabbix-apache-conf
and make the necessary changes to this file.
6 Review component configuration parameters
See the upgrade notes for details on mandatory changes.
7 Start Zabbix processes
Start the updated Zabbix components.
# systemctl start zabbix-server # systemctl start zabbix-proxy # systemctl start zabbix-agent
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 between minor versions of 4.4.x (for example, from 4.4.1 to 4.4.3). Upgrading between minor versions is easy.
To execute Zabbix minor version upgrade it is required to run:
$ sudo yum upgrade 'zabbix-*'
To execute Zabbix server minor version upgrade run:
$ sudo yum upgrade 'zabbix-server-*'
To execute Zabbix agent minor version upgrade run:
$ sudo yum upgrade 'zabbix-agent-*'
Note that you may also use 'update' instead of 'upgrade' in these commands. While 'upgrade' will delete obsolete packages, 'update' will preserve them.
