installation fails: Can't connect to local MySQL server through socket

[hsv]

Hi
A new installed Ubuntu 20.04.2 fully updated

Following steps has been used (Steps are from here: Download Zabbix)
#Install Zabbix repository
wget https://repo.zabbix.com/zabbix/5.4/u...u20.04_all.deb
sudo dpkg -i zabbix-release_5.4-1+ubuntu20.04_all.deb
sudo apt update
#Install Zabbix server, frontend, agent
sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-sql-scripts zabbix-agent
#Create initial database
sudo mysql -uroot -p
"passwod"

And now the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

ls -ll /var/run/mysqld/
ls: cannot access '/var/run/mysqld/': No such file or directory

So what has gone wrong here?

regards
Henning

Please install MySQL server. If you use the official Zabbix package, you may use a remote MySQL server, so the MySQL server will not be installed locally automatically.
