mbstring PHP extension and mcrypt extension error

[mnzava]

Hi all,
I hope you are OK. After setup my server based on PERFECT SETUP ON CENTOS 5.0 (This server doesn't have ISPConfig installed. It is just perfect setup installation). I came across these two errors just after installation of phpMyAdmin 2.11.3.

The errors are as follows:

The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.

and another error is..

Cannot load mcrypt extension. Please check your PHP configuration.

How do i correct these errors?

Second question,
In perfect setup you said we should disable Security Level and SELinux. That's OK as long as ISPConfig will be installed because it has its own firewall, but i'm thinking of security issue based on my settings without ISPConfig. Should i enable Security Level and SELinux or Security Level only?

I didnt install ISPConfig on this other server because it is for single site purpose.

Thanx in advance,
Mnzava

Run

yum install php-mbstring

and restart Apache.

You can switch on the firewall if you like, but I wouldn't enable SELinux...
