Problem Zabbix agent Centos 7

[aerodesliza]

Hi everyone,
I'm trying to run Zabbix agent on Centos 7 following theses steps: https://tecadmin.net/install-zabbix-...n-centos-rhel/.
zabbix-agent-4.0.25-1.el7.x86_64 was installed successfully:
Running transaction
Installing : zabbix40-4.0.17-1.el7.x86_64 1/1
Verifying : zabbix40-4.0.17-1.el7.x86_64 1/1

Installed:
zabbix40.x86_64 0:4.0.17-1.el7


I configured the zabbix_agentd.conf file, but when I try to start Zabbix Agent service I got:
[root@lme ~]# systemctl start zabbix-agent
Failed to start zabbix-agent.service: Unit not found.

I'm lost here... any advices?

Thanks

Which package did you install?
- zabbix-agent-4.0.25-1.el7.x86_64
- zabbix40-4.0.17-1.el7.x86_64

If you want to use the official Zabbix package, please install the package "zabbix-agent". It is not "zabbix40".
Also, the package "zabbix40-4.0.17-1.el7.x86_64" does not include the agent. Probably it is a package published by EPEL, but "zabbix40-agent" is the name of the package of Zabbix agent published by EPEL.
If you want to install using Zabbix official package, register official Zabbix 4.0 repository and install the package named "zabbix-agent" as described in the site referred to again.

Thanks, I didn't notice I installed the wrong package. You're the best!
