Zabbix 6.0 Installation with RPM Packages(Server No Connectivity to Web)

[Bacil123]

Hello All. We're installing Zabbix 6.0 manually step by step. We did manage to install lots of PKGs except Two. When we install : zabbix-web-mysql-6.0.39-release1.el9.noarch.rpm, it says it needs : zabbix-web-deps-6.0.39-rc1.release1.el9.noarch. So, we install web-deps. But that further asks that it needs : zabbix-web-database-6.0.39-rc1.release1.el9.noarch. But this web-database is no where there in the repo.zabbix.com, neither in non-supported/rhel/X. So, how to get this RPM. Note: All other 6 mandatory PKGs got installed successfully. Please advise. Best...

Which Linux distribution?
Which Frontend (apache/nginx) and DB (mysql/postgres) did you pick?

[Bacil123]

Hi. Thanks. Red Hat Enterprise Linux release 9.4 (Plow).
Yes, that was my next query which I was about to raise. Do we need to have first get DB installed on host and apache installed as well first. As in next steps of installation, when I run this: ]# mysql -uroot -p
-bash: mysql: command not found. So there is no mysql there. Thanks.

'zabbix-web-database' is a virtual provide, provided by any of the zabbix-web-mysql-6.0.XX packages:

$ cd /tmp/
$ wget https://repo.zabbix.com/zabbix/6.0/rhel/9/x86_64/zabbix-web-mysql-6.0.39-release1.el9.noarch.rpm
$ rpm -q -l --provides zabbix-web-mysql-6.0.39-release1.el9.noarch.rpm
warning: zabbix-web-mysql-6.0.39-release1.el9.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID 08efa7dd: NOKEY
zabbix-web-database = 6.0.39-release1.el9
zabbix-web-mysql = 6.0.39-release1.el9
(contains no files)

Packages do that so that they are sure you have one of the supported database options installed, while allowing you to decide which DBMS you want to use.

As the rpm query output shows, it actually doesn't install any files. It's just there for handling dependencies.

As far as why you're getting a dependency error: It's probably circular dependencies between the two packages. You want to install both packages at the same time (list both on the command line, one after the other). librpm (and yum/dnf that builds on top of it) has the notion of a "transaction". For circular or transitive dependencies, you just need to make sure all the packages are installed in the same transaction.

Hi. Thanks for the information. Since I don't have internet connection(due to restrictions), thats why I am installing it manually.

Note: php-fpm, php-gd and php-mbstring, were installed successfully as well. Not sure why it complaints about them as well.

What is the output of:

rpm -qa | grep zabbix

I didn't get which web frontend are you intending to use (apache or nginx). I did a quick Rocky 9 vm deployment in my proxmox lab and followed the installation instructions from the Zabbix site which calls for the following packages using the EL9 repo (assuming apache/mysql for frontend/backend):

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent

These are the packages that got installed for a mysql/apache deployment:

zabbix-web-6.0.39-release1.el9.noarch
zabbix-agent2-plugin-postgresql-6.0.39-release1.el9.x86_64
zabbix-agent2-plugin-mongodb-6.0.39-release1.el9.x86_64
zabbix-web-deps-6.0.39-release1.el9.noarch
zabbix-web-mysql-6.0.39-release1.el9.noarch
zabbix-apache-conf-6.0.39-release1.el9.noarch
zabbix-server-mysql-6.0.39-release1.el9.x86_64
zabbix-agent2-6.0.39-release1.el9.x86_64
zabbix-sql-scripts-6.0.39-release1.el9.noarch
zabbix-selinux-policy-6.0.39-release1.el9.x86_64

As for your other question, yes, you do need a MySQL or PosgreSQL instance and the proper access to it in order for the Zabbix installation wizard to create the necessary schema in it. It can be running locally on the same server as Zabbix or on a different server.

[Bacil123]

Hi. Thanks. Haha. I even don't know that requirements: Are apache or nginx also freeware tools, and easily available.

# rpm -qa | grep zabbix
zabbix-release-6.0-5.el9.noarch
zabbix-selinux-policy-6.0.39-release1.el9.x86_64
zabbix-agent-6.0.39-release1.el9.x86_64
zabbix-server-mysql-6.0.39-release1.el9.x86_64
zabbix-web-6.0.39-release1.el9.noarch
zabbix-sql-scripts-6.0.39-release1.el9.noarch

I'll try to get all the missing ones as per your list. Right now, I have:
zabbix-release-latest-6.0.el9.noarch.rpm - Got installed
zabbix-server-mysql - Got installed
zabbix-web-mysql - Not got installed yet
zabbix-apache-conf - Got installed
zabbix-sql-scripts - Got installed
zabbix-selinux-policy - Got installed
zabbix-agent - Got installed
zabbix-web-database - Not got installed yet
zabbix-web-deps-6.0.39-release1.el9.noarch.rpm - Not got installed yet

And, again will see how to get MySQL or PosgreSQL instance on this box, as I am quite new to these things. Best...

The web frontend for Zabbix can run on Apache or Nginx. The choice of which to run is up to you. I prefer Nginx over Apache but that's just me. The packages for them should be available via the Red Hat repos already configured on your server, but you are going to have a very hard time trying to resolve all the related package dependencies if your host is not allowed to connect to the repos hosting them.

[Bacil123]

Hi. Thanks.
Please advise on the below three items:
1. I see some apache running on this server. Can we use it. For sure it is being used by another APP. But can we use the same for Zabbix.

2. I also some PostGres SQL instance on server for another purpose or in use by another APP. Can we use the same PostGres, or it has to be dedicated ONLY.

3. Please share the command to install Ngix, like "sudo yum install ngix".

Thanks.

Hi. Thanks. I finally was able to manually install nginx from a tar.gz download+PCRE Library tar download, on same host where apache4 was installed. As you had referred it will be hard to resolve dependencies packages for nginx, but somehow it only asked for PCRE library. After installation, when I start nginx, it complains: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use), which is perfectly fine as Apache is using it so I stopped Apache and again start ngnix: # /usr/local/nginx/sbin/nginx.
# ps -eaf | grep -i nginx
root 69056 1 0 18:09 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nginx 69057 69056 0 18:09 ? 00:00:00 nginx: worker process
root 69256 55038 0 18:10 pts/0 00:00:00 grep --color=auto -i nginx
# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.27.4
built by gcc 11.4.1 20231218 (Red Hat 11.4.1-3) (GCC)
configure arguments: --user=nginx --group=nginx

But then when I check status with : # sudo systemctl start nginx
Failed to start nginx.service: Unit nginx.service not found.
Do I have to create some systemd service etc. Or, some Unit. Not sure what is the Unit.

Any idea, how to start nginx.service and use it for Zabbix.
Another thing is there is no file like /etc/nginx/conf.d/zabbix.conf also in the server.
Thanks.

[jhboricua]

You need to change the port nginx is trying to bind to in its configuration file, as apache is already using it. That said, you're better off installing Zabbix on a dedicated server or VM, I have no experience setting up zabbix the way you are trying to do it. It's probably not even supported that way.

If you're just doing this on a lab fashion, have you looked at the Zabbix virtual appliance? Might be easier to deploy and play with Zabbix that way as it already comes with everything pre-installed. if this is for a produciton deployment, I feel you are going the wrong way about it. Get a dedicated server or VM for it and get an exception to allow it to connect to the internet until the software is installed and anytime you need to updated it. The installation doesn't need to be this difficult.

[Bacil123]

Hi. Thanks. This has become kind of dedicated host now, as I have stopped Apache altogether and that another App is not working due to that also. So dedicated. I can also reach to Nginx default page in browser all fine as well as of now.
See below all good as of now. Only thing is to integrate it with Zabbix Server/Agent etc.

So, the below issue mentioned earlier has been resolved as of now. From a non-zabbix google search, a file was modified at this location: /lib/systemd/system/nginx.service
[Unit]

ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target
And, then restarting nginx brought back it up fine.

NOTE: The below issue referred earlier has been resolved.
# sudo systemctl start nginx
Failed to start nginx.service: Unit nginx.service not found.
Do I have to create some systemd service etc. Or, some Unit. Not sure what is the Unit. <= This issue has been resolved as of now: UPDATE


Please advise. Thanks in advance. Best
