New Server Offline installation. CentOS

[smounche]

Hello,

I am new to Zabbix and would like to install it in our organization.
The installation needs to be done in an environment without internet access, so I require guidance for performing an offline installation.
I need to pre-download all the necessary files and packages, have them checked for integrity by my organization, and then install them locally on a server.
Is there an easy step-by-step guide available for this process?

I plan to install the latest version (6.4) on CentOS.

Thanks.

You could install it from source:

https://www.zabbix.com/documentation/6.4/en/manual/installation/install

I wouldn't go there if I was you.

but why from source.. Go to https://repo.zabbix.com/zabbix/6.4/rhel/ choose your centos version (8 or 9) and download all the rpm-s you need. But you also need rpm-s for DB and webserver, which is not part of Zabbix installation...
Is there an easy step-by-step guide available for this process? No... as it is quite uncommon way of doing things... You need to be quite familiar with installing things from local packages and resolving all the prerequisites for all of them...

Yeah, I did missed that .

The alternative way: get another machine with exactly same OS but with access to internet. Prepare offline repository with all packages you might need (on centos 7 yum was downloading all dependencies automatically). Then tarball the offline repo and move it your offline server. Unzip your offline repo, configure it as one of repositories - do normal installation from this offline repository.

Command wise for Centos 7 (did not do such on newer version on Centos, but was able to replicate similar logic on Ubuntu 22) it was something like:
Install prerequisite packages

 #yum install yum-plugin-downloadonly yum-utils createrepo​

Create two dir. One is instalroot for dependency resolution and one for actual packages:

# mkdir /var/tmp/zbx-repo
# mkdir /var/tmp/zbx-repo-installroot

Get the packages you need(not a full list, just example):

#yum install --downloadonly --installroot=/var/tmp/zbx-repo-installroot --releasever=7 --downloaddir=/var/tmp/zbx-repo mariadb net-snmp vim ...

Create repo from downloaded packages:

createrepo --database /var/tmp/zbx-repo
​​​

Tarball resulting folder:

tar -czvf offlinerepo-zbx.tar.gz zbx-repo

Move the archive to targeted offline machine. Extract tarball. Create a repository config file pointing to local folder where you extracted the tarball. Install needed packages from local repo (like #yum --disablerepo=\* --enablerepo=offline-zbx install vim)

Still would not call it a simple task, but might be way easier then dealing with all the dependencies manually.

Thank you for that link.

can you please tell me what each one on this infrastructure means?

And another question, how do I know what rpm-s I need?

You need stuff from x86_64. But if you already ask things like what do you need from there ... You should probably try what ISiroshtan suggested... It should resolve your dependencies at once and you should get all needed rpm-s downloaded... If that sounds like rocket surgery.. try to find a friendly linux admin to do this for you ...

Getting my proposed solution acknowledged by forum long time member makes me happy
... even tho it's not exactly a Zabbix solution

I learned something from it also... I now know that its possible this way.. Never done it before... but maybe one day I need it.
