Hi @umarzaib136,

Can you please let me know which article you are following?

Additionally, if you don’t have the netstat command, you can always install it by doing:

For Ubuntu

apt install netstat

For CentOS

yum install netstat

As for the error establishing database connection, it can be related to a lot of stuff. Your website might be using the wrong credentials to connect to your Database, your MySQL service might be down or you don’t have any.

As such, can you please provide us with a little bit more information what is your setup, has this worked before, have you made any changes recently if it worked before and basically, all the information you can think of?
