Can you try the below mentioned approaches:

Firstly check if MySQL or MariaDB server is started. Check service mysql status

Specify as the host instead of localhost. That is, mysql -h -u root instead of mysql -h localhost -u root. If you omit the host (mysql -u root), the MySQL client will implicitly use localhost.

For SingleStoreDB Cloud, change the socket value in the /etc/mysql/my.cnf file to the location of your SingleStoreDB Cloud socket file.

This should help resolve the issue.

  • I tried to check as below but it failed...

    mysqladmin -u root -p ping

    mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local server through socket '/opt/bitnami/mariadb/tmp/mysql.sock' (111)' Check that mariadbd is running and that the socket: '/opt/bitnami/mariadb/tmp/mysql.sock' exists!
