But after a succesful installation, I even get this error saying that I dont have pdo_mysql installed on the server.

pdo_mysql extension is not installed

I don’t get it, when I check with function

<?php
phpinfo();
?>

pdo and pdo_mysql is there.

'--enable-pdo=shared'
'--with-pdo-mysql=shared'

So, it’s time for searching and lurking into Google and Magento forum/docs

Almost an hour, until I found this thread, it says I need to add these lines into php.ini. I have root access to server so it does not problem for me, but about other who just using shared hosting?

; added when pdo_mysql is shared (or missing)
extension=pdo.so
extension=pdo_mysql.so
extension=pdo_sqlite.so

Turns out, it’s not necessary system php.ini, I was misunderstand, and when I look on magento install dir, I found php.ini file, edit the file with above line. Open Magento URL, and there you go, Magento installation running succesfully.

The MIME types associated with PHP may have changed.
If you experience problems with PHP related settings in .htaccess files, ensure
those files use the MIME types specified above (the first value listed after AddType.)

php.conf updated to:

So your webhosting provider activated “Prevent “nobody” from sending mail” which cause your PHP script can’t sent email? You can use PHP classes called XpertMailer or PHPMailer but somehow it’s not working well on my host. Weird… The previous version XPertMailer works like charm but somehow the new one never sent my emails.

So I googling around and found Webmaster World’s Forum, and luckily the ini_set function is not disabled. So I test the script and it works flawlessly. Below is the script

<?PHP
/* Setup your To, Subject and Message Body */
$to='MyRealName <me@mydomain.com>';
$subject='Testing PHP Email';
$body='Put Your Text Message Here.';

/* Specify your SMTP Server, Port and Valid from Address */
ini_set("SMTP","mail.mydomain.com");
ini_set("smtp_port","25");
ini_set("sendmail_from","me@mydomain.com");

/* Additional Headers */
$headers = "from:MyRealName <me@mydomain.com>\r\n";
//$headers .= "Cc:RealCCName <ccUser@theirdomain.com>\r\n";
//$headers .= "Bcc:RealBCCName <bccUser@theirdomain.com>\r\n";

/* Try to send message and respond if it sends or fails. */
if(mail ($to, $subject, $body, $headers )){
echo "<h2>Your Message was sent!</h2>";
}
else{
echo "<font color='red'><h2>Your Message Was Not Sent!</h2></font>";
}
exit;
?>

PS: email account me@mydomain.com should exist and password should be correct

Now what should I do if the disable function ini_set also?? Hmm…???
