Answer

Hello,

Can you try the below mentioned approaches:

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

Specify 127.0.0.1 as the host instead of localhost. That is, mysql -h 127.0.0.1 -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.
