Hello,

I am installing the last version (22.04) open source of centreon but I encounter problems.


I'm going with a distributed architecture (1 central machine, 1 database and pollers).


All my VMs are freshly installed OS whose characteristics are as follows:

[root@sup-cent-01 ~]# cat /etc/centos-release
AlmaLinux release 8.6 (Sky Tiger)
[root@sup-cent-01 ~]# uname -m
x86_64
[root@sup-cent-01 ~]# uname -r
4.18.0-372.16.1.el8_6.x86_64
 

I want to install via packages, I followed this procedure:

https://docs.centreon.com/docs/installation/installation-of-a-central-server/using-packages/

 

My problem is that on the central, arrived at step (With a remote database / Run the following command on the Central server:) “dnf install -y centreon-central” I encounter these errors:

[root@sup-cent-01 ~]# dnf install -y centreon-central

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
 

I admit that I am neither an expert in centreon nor in linux and I wonder what I should do.
Maybe I should try to install an older version of centreon?

 

Thanks

Cordially

Hello @mc.gyver.reboot 

 

If you want to get started quickly I suggest to use the VM's provided by Centreon and these links

 

https://docs.centreon.com/docs/installation/installation-of-a-central-server/using-virtual-machines/

https://download.centreon.com/

 

You might also be interested in looking at the available architectures link to look for one that matches your setup

https://docs.centreon.com/docs/installation/architectures/#available-architectures

Hi @mc.gyver.reboot , I try this morning an installation on Centreon on Alma 8.6 following the documentation without problem.

Hello, @hmorales ,

In fact I know a little centreon (I'm not a pro but I have notions).
I currently have an installation with several thousand hosts (an old version under centos 6) that I need to migrate to a new infra. The current architecture is distributed and I want to continue to be in this configuration.
Unless I am mistaken, the packaged version of centreon does not allow (well at least with version 22.04 under alma) to create such an architecture, please correct me if I am wrong.

 

Thanks

@mc.gyver.reboot of course you can continue to install a distributed architecure:

And to migrate data from old Central server: https://docs.centreon.com/docs/migrate/introduction/

@Laurent 

In fact I already follow these procedures (and I don't think I was wrong until now with the commands to type).
I am at the “Step 2: Installation” part, "With a remote database” and at the first command I have the problem (dnf install -y centreon-central)

https://docs.centreon.com/docs/installation/installation-of-a-central-server/using-packages/#step-2-installation

 

Basically I haven't done anything yet except to install the OS, install the repo (disable the security part)

 


Note that my version is apparently too old (v2.8) to switch to a modern version of ceontreon. I'm starting from scratch.

 

Thanks

Complete!

 

Can you try to execute again the following 2 commands:

dnf module reset php
dnf module install php:remi-8.0

A huge thank you @Laurent  !
I was able to solve the problem with the commands:

dnf module reset php
dnf module install php:remi-8.0

Having VM I have made several attempts, it turns out that following the installation of the centreon-release package I cannot launch my installation command for centreon.

If I repeat the commands below after installing the centreon-release package, it's OK.

dnf module reset php
dnf module install php:remi-8.0
