WordPress requirements.

Hi all,
I have a wordpress site installed on a virtual server, and I just wanted to check how to update to the following:

MySQL version - currently at 5.5.47 - they recommend a minimum MySQL version of 5.6.

SoapClient class is not enabled

Your server does not support the mbstring functions.

Can I easily sort these three issues?

The server is CentOS 7 64 bit. Currently have version 5.6.5 and 5.4.16 of PHP installed.

Thanks in advance,

Hi, I have the same problem, have you found how to fix it? a greeting
