Can't set mysql database in SSH - mysql

Question

I am using a VPS Ubuntu 20.04 in a2 hosting. I am trying to set up my mysql database but I am getting some error. I am doing this through a SSH. I installed mysql using
sudo apt-get install mysql-server mysql-client
and it installed just fine. But when I try to run
sudo mysql_secure_installation
it throws me this error
Error: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
I have tried to reinstall mysql-server, but without success. I have noticed some errors:
In my /etc/mysql/my.cnf file, it looks like is missing some code, I just have this:
It doesn't have any information about the socket.
My /var/run/mysqld/mysqld.sock file was not created when I installed the db. Not even the folder /var/run/mysqld was created. I tried to create both, but it still doesn't worked. In my example, the files are being created in a wrong way ou not even being created. I don't know why this is happening.
FIle: /etc/mysql/mysql.conf.d/mysqld.cnf

# * Basic Settings

# socket = /var/run/mysqld/mysqld.sock

# changed. Ref https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_tmpdir

#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.

mysqlx-bind-address = 127.0.0.1

# * Fine Tuning

# * Logging and Replication

# Log all queries
# Be aware that this log type is a performance killer.

# The following can be used as easy to replay backup logs or for replication.

Is there anything I am missing? If someone could help me I would be grateful. Thank you!

For anyone who have the same error, I solve this by reinstalling my entire OS. My ubuntu version was 20.04 and I installed the 18.04 version. This solved for me.
