Ubuntu 14.04 server: problem with Apache2 with phpMyAdmin

Question

I installed Apache 2 and it works fine. I installed PHP 7 and everything works fine, but when I install phpMyAdmin, Apache 2 stops working. When checking Apache 2, it doesn't even load the default page.

When I restart Apache 2, the following error appears:

root@ip-172-31-30-202 :~# service apache2 restart * Restarting web server apache2 [fail] * The apache2 configtest failed. Output of config test was: Segmentation fault (core dumped) Action 'configtest' failed. The Apache error log may have more information. 

The error log has:

I am using Ubuntu 14.04 (Trusty Tahr).

Answer 1

The problem is solved by removing Apache 2:

 sudo apt-get purge apache2 

I installed phpMyAdmin:

 sudo apt-get -y install phpmyadmin 

Then I installed apache2 :

 sudo apt-get install apache2 

Answer 2

This worked for me:

 cd /etc/apache2/mods-enabled rm php5.conf rm php5.load sudo service apache2 start; 

It worked :)))))

See also apache2 segfault after upgrade .

Answer 3

Run this command in terminal:

 vim /etc/apache2/apache2.conf 

Add the following to the bottom of the file:

 # phpMyAdmin Configuration Include /etc/phpmyadmin/apache.conf 

Then restart Apache:

 sudo service apache2 restart 

Answer 4

Apache does not reset the kernel by default. Take a look at http://www.omh.cc/blog/2008/mar/6/fixing-apache-segmentation-faults-caused-php/ .
