Zabbix 6.0 High Availability ( HA Cluster ) Setup Tutorial
HTML-код
- Опубликовано: 13 мар 2022
- Detailed tutorial on how to configure Zabbix with native high availability functionality that was introduced in Zabbix 6.0 LTS version. Eliminate single point of failure, and use simple out-of-the-box functionality instead of complex third-party tools for HA setup.

What if we shut down Node1 which have frontend and nginx?
It`s not HA if your database is on one node.
One can split DB and zabbix server
Thanks, very informative!
Thank you!
Thanks man. Very informative 🙏
Thanks you!
Without frontend, how to monitor your devices when the main server goes down ?
Regarding the HA, when Node1 is down, the connections will transfer to node2... how about when node1 is now UP, will it automatically transfer to node1 as Active?
Great Man
what happen if physical / virtual host goes down with database and front-end ? do we need to install DB/server/front-end in different servers to get full functionality in ha systems ?
Seems this native HA cover zabbix-server only. I whether backup the full system than using this Server HA only solution 🤔
Hi, is the HA solution designed for the frontend or is it for the agents?
How to do it with SNMP? How to tell it there is another zabbix node?
Can we cluster between zabbix 5.0 to zabbix 6.0
Can you use HA with agent versions < 6.0?
How about frontend high availability?
Hey Dmitry, Let's say that the DB is install separately and also two zabbix servers, 101 and 102 (just like your video) Is there any way to install frontend on 102 so that if 101 in down and the DB is still up and running the zabbix frontend will still be running also ? Thanks 🙌
Sure, you can have frontend and server on same machine on each node
Hi Dimitry, I have a question for you. Does zabbix support multiple active master instances?
Not yet
What flavour of linux would you pick besides oracle linux? Rocky or alma?
RHEL? :)
I think it's misleading to say that Zabbix offers HA functionality when it really doesn't. The DB is on one node only, so how r u supposed to access the web management interface or DB when node 1 is offline?
Zabbix offers HA for zabbix component. Databases and web engine are mandatory, but not part of zabbix software. There are other ways to have database and web ha
@@DmitryLambert Care to show us how to achieve HA for DB and frontend? Thanks!
@@sjuarez2000 I second this!
Hi, thank you for the video. I would like to ask, what happens when I install the DB on separate machine, and the DB will be unreachable. Will the two zabbix-servers keep their active-standby statuses? Will I get notification about the DB unreachability from the active server? Or will just crash my monitoring system? Thank you.
If the database in inaccessible, you get a notification from active Zabbix. But cluster status and info which node is active and which passive is stored in database, so that info can't be changed without connection to db.
Thank you, @@DmitryLambert
Even with this High Availability has a failure point at DB, am I right ?
Yes, native HA is for server only
@@DmitryLambert why there is nothing about database? Can it be something like circular (or master-master) replication for the DB?
I was working on Zabbix HA today and came across this video. Zabbix doesnt actually offer a real HA solution apparently, even though they claim to do so on their webpage. For example, in this video, you only have one database, which means if that fails, your installation is gone. Hence the video is misleading. I will try to install a true Zabbix HA cluster using Galera replication.
Don't forget that Zabbix software is "Zabbix", not the database. For fully operational stack of course database and frontend are required, but it's not really Zabbix's responsibility to set that up. Especially, because there might be different database engines used.
You can use native Zabbix server HA, and configure DB replication and master/master web engine yourself.
@@DmitryLambert Can you do a tutorial on setting up a replication DB with failover and master/master web engine please, your tutorials are the best and easiest to follow along too and i think many of us would really enjoy such a tutorial.
How is the frontend configuration if it is installed on a separate server? need a vip ip?
Frontend gets active server IP from Database
@@DmitryLambert tnks!
@@DmitryLambert how can we access frontend page if 101 is shutdown as only zabbix-server-mysql was installed in 102??
@@DmitryLambert so do we need to have a separate frontend for the standby node as well?
