Problem showing information on my Dashboard

Hello
I have a problem with a Zabbix installation

A new installation of version 6.4.17 was carried out offline and the following packages were installed:
# yum install zabbix-server-mysql-6.4.17-release1.el8.x86_64.rpm
# yum install zabbix-web-6.4.17-release1.el8.noarch.rpm zabbix-web-deps-6.4.17-release1.el8.noarch.rpm
# yum install zabbix-web-mysql-6.4.17-release1.el8.noarch.rpm zabbix-web-service-6.4.17-release1.el8.x86_64.rpm
# yum install zabbix-proxy-mysql-6.4.17-release1.el8.x86_64.rpm
# yum install zabbix-get-6.4.17-release1.el8.x86_64.rpm
# yum install zabbix-sql-scripts-6.4.17-release1.el8.noarch.rpm
# yum install zabbix-selinux-policy-6.4.17-release1.el8.x86_64.rpm
# yum install zabbix-apache-conf-6.4.17-release1.el8.noarch.rpm

On a RHEL 8 server, however within that server I already had a MySQL database running and other Web applications.

When I try to verify the logs it shows me the following error:
connection to database 'zabbixdb' failed: [20 02] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.soc

and In my dashbord it tells me that the Zabbix server is not running.

Can anyone help us with this problem?

Thanks
Enzo.
