Apache2 unable to start

j-ray · 03-31-2015, 01:53 AM

Blank pages in php sites often point to errors that are not displayed.
In /etc/php5/apache2/php.ini
set
error_reporting = E_ALL
display_errors = 1;

What happens if you direct your browser to
http://localhost/xyz/index.php instead of http://localhost/xyz ?

Probably the server does not send a default index.php because it is not yet configured to do that. Something like the following may help:
<Directory>
DirectoryIndex index.html index.php index.phtml
</Directory>

For phpMyAdmin you need a running mysql server and you have to set the connection data correctly.

Hi,

Thanks for your advice. Mint 17 looks very strange to me.

$ ls /etc/php5/

Code:

cgi  cli  conf.d  mods-available

Apache2 is NOT there

$ ls /etc/php5/cgi/

Code:

conf.d  php.ini

php.ini is here

Edited php.ini as follows

Code:

change - error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
to - error_reporting = E_ALL

change - display_errors = Off
to - display_errors = 1

$ sudo service apache2 restart

On browser ran;
1) /localhost/xyz
blank page displayed

2) /localhost/zyz/index.php

Code:

Not Found
The requested URL /xyz/index.php was not found on this server.
Apache/2.4.7 (Ubuntu) Server at localhost Port 80

$ apt-cache policy php5

Code:

php5:
  Installed: (none)
  Candidate: 5.5.9+dfsg-1ubuntu4.7
  Version table:
     5.5.9+dfsg-1ubuntu4.7 0
        500 http://archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages

     5.5.9+dfsg-1ubuntu4 0
        500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

php5 NOT INSTALLED ???

Then start a Mint 16 VM with Apache2 running
$ ls /etc/php5/

Code:

apache2  cli  conf.d  mods-available

apache2 is there

$ apt-cache policy php5

Code:

php5:
  Installed: (none)
  Candidate: 5.5.3+dfsg-1ubuntu2.6
  Version table:
     5.5.3+dfsg-1ubuntu2.6 0

     5.5.3+dfsg-1ubuntu2 0
        500 http://archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages

php5 NOT installed?

I'm stuck here.

sudo apt-get install php5

To install php with apache modules, take a look at step 3 at the link below. I don't know if you are using or have mysql but that is also expalined if needed. If you changed your Document Root back to /var/www/html, do you have an info.php file there and if so, what happens when you point to it from your web browser.

Hi,

Thanks for your advice.

Performed following steps;

DocumentRoot /var/www/html
$ sudo ln -s /var/www/info.php /var/www/html/info.php
$ sudo ln -s /var/www/xys /var/www/html/xyz

On browser http://localhost/xyz/info.php

Code:

Not Found

The requested URL /xyz/info.php was not found on this server.
Apache/2.4.7 (Ubuntu) Server at localhost Port 80

http://localhost/hymn/index.php
A blank page displayed

I couldn't recall exactly the steps performed previously to install LAMP. But I can confirm this VM was working properly before upgrade from Mint 16 to Mint 17. Same as other VMs running on Mint 16 are now working without problem.

satimis,

I could be totally wrong but in Linux Mint 17 I think you need to configure apache2.conf to work with Phpmyadmin.

Code:

gksudo gedit /etc/apache2/apache2.conf

Copy and paste the following line at the bottom of the file, save and quit.

Code:

Include /etc/phpmyadmin/apache.conf

Then restart Apache:

Code:

sudo service apache2 restart

Hi beachboy2,

Thanks for your advice.

Performed your steps. Restarted apache2 including reboot VM.

On browser
/localhost/phpmyadmin
only codes displayed.

/localhost/xyz
only blank page displayed

satimis,

When I last set up a LAMP server on Ubuntu, just for test purposes, I followed this HowTo:

http://tuxtweaks.com/2012/04/install...cise-pangolin/

Everything worked fine without any errors.

Comments at the end of the piece suggest that Linux Mint 17 also works.

I hope you manage to track down the cause of the error.
