Hey,

i´m trying to configure an server like here:

http://www.howtoforge.com/the-perfect-server-opensuse-13.1-with-apache2-mysql-php-postfix-and-ispconfig-3-p5

Everything is working fine. But after installing squirrelmail.. i can not start apache anymore..

Code:

 systemctl start apache2.service

Code:

Job for apache2.service failed. See 'systemctl status apache2.service' and 'journalctl -xn' for details.

Code:

 Main PID: 3886 (code=exited, status=1/FAILURE)
   Status: "Total requests: 0; Current requests/sec: 0; Current traffic:   0 B/sec"

Does anybody know why that is happening?

Thx

 

Hi Thank you for your answer!

It is already installed.

But I don't know how to enable.. Or how to check the status..

 

with:

Code:

a2enmod apache2-mod_php5

?

 

I got it.

a2enmod php5
