Unable to connect to the specified MySQL server No such file or directory

I dont understand why it is saying this, MySQL service is running and yet its not allowing me to continue with the ispconfig3 install.

I reinstalled mysql to see if that would fix it but it did not... Any ideas?

Running Centos 6.2

 

Single.

I found out the problem pretty stupid if you ask me... ISPConfig 3 DOES NOT install with a fully up to date version of MySQL 5.3.23 when i uninstalled all updated packages from sql and installed a older version ISPConfig went through with the install...

However another problem has come up everything works fine but for some reason my php.ini located at /etc/php.ini keeps getting erased... This happens every time i reboot the computer or log off of the root account it does not make any sense. I noticed this because when i logged into ispconfig there were alerts and warnings everywhere when i turned them off.

Also i am having an issue installing APC pecl says APC has been installed however it is not showing up in my wordpress website. XCache is horrible as it will not empty its cache when requested too, Not to mention practically doubles my sites load times.

And finally the email works (thank god) but i cannot send out emails. I made an account i can login on outlook and receive mail but i cannot send mail. I tried sending a test message to my hotmail account with no luck.
When i setup hMailserver on windows i had to set the outgoing imap to smtp.comcast.net to be able to send mail out where would i set that in ispconfig?

 

Being on par with APC or not XCache does not work well on my server. So how do i install APC correctly?

I am using W3 Total Cache for my wordpress site and it works best with APC.

Also the Relayhost is where i put the smtp.comcast.net right? Do i need a username and password? If so how would i get those?
EDIT: Mail has been received in my hotmail, thanks
EDIT: SMTP Mail (Logged in account mail) works fine but it seems website mailing does not work, any suggestions on this?
