I just upgraded from 14.10 to 16.04 and am not sure how to configure PHP 7 in apache. I did modify the php7.0.conf file to uncomment that last lines, restarted apache2 and no change.
Do I need to change the apache2 setup to allow php?
PHP works from the command line so I am sure the php is properly installed.
Additionally, I get an error on phpadmin saying that the mbstring is missing.
Just like before, you have to install PHP for Apache.
From the Server Guide:
sudo apt install php libapache2-mod-php
That command will install PHP and the Apache 2 PHP module. Simply configure Apache as before (sudo a2enmod php7.0, I think, will turn on the module).
Your mbstring issue is similar - you need to install that extension:
sudo apt install php7.0-mbstring
For other missing modules there will be similar things to have to install as well.
To configure php7 to run with your server you need to do some configuration:
1. Make sure you remove any traces of php/php5
Open a terminal Ctrl+Alt+T and:
cd /etc/apache2/mods-enabled
ls -la
The output should not contain any php5.conf or php5.load, but if it does, do the following:
# this is the proper way of disabling modules
sudo a2dismod php5
# run this only if the above command didn't remove the php5 sym-links
sudo rm php5.load
sudo rm php5.conf
Now add the php7.0.conf and php7.0.load instead:
# this is the proper way of enabling modules
sudo a2enmod php7.0
# run this only if the above command didn't create the php7.0 sym-links
sudo ln -s php7.0.conf ../mods-available/php7.0.conf
sudo ln -s php7.0.load ../mods-available/php7.0.load
The output of ls -la php* should look like this:
lrwxrwxrwx 1 root root 29 Apr 15 03:55 php7.0.conf -> ../mods-available/php7.0.conf
lrwxrwxrwx 1 root root 29 Apr 15 03:55 php7.0.load -> ../mods-available/php7.0.load
After dealing with the modules we now come to the /etc/apache2/conf-enabled directory. Remove any traces of php/php5 here as well by sudo rm <name>
Then, if needed do:
# the proper way of enabling configs
sudo a2enconf php7.0-cgi
sudo a2enconf php7.0-fpm
# do those commands only if the above didn't work out
sudo ln -s php7.0-cgi.conf ../conf-available/php7.0-cgi.conf
sudo ln -s php7.0-fpm.conf ../conf-available/php7.0-fpm.conf
The output of ls -la php* should look like this:
lrwxrwxrwx 1 root root 33 Apr 21 17:00 php7.0-cgi.conf -> ../conf-available/php7.0-cgi.conf
lrwxrwxrwx 1 root root 33 Apr 21 17:01 php7.0-fpm.conf -> ../conf-available/php7.0-fpm.conf
2. Restarting Apache2
Before restarting Apache make sure to clean out the Apache error.log then restart:
sudo su
> /var/log/apache2/error.log
exit
sudo service apache2 restart
Now check the error.log by issuing cat /var/log/apache2/error.log | less (piping through less enables you to easy scroll up and down, q exits the output).
If your error.log contains many (and I literally mean a heap of) some MIBS not found do the following:
sudo apt install libsnmp-dev
sudo net-snmp-config --snmpconfpath
sudo apt-get install snmp snmp-mibs-downloader
sudo su
> /var/log/apache2/error.log
exit
sudo service apache2 restart
The check again the error.log it now should only contain 3 lines:
[Sat Apr 23 01:39:07.504005 2016] [mpm_prefork:notice] [pid 1647] AH00169: caught SIGTERM, shutting down
[Sat Apr 23 01:39:08.685774 2016] [mpm_prefork:notice] [pid 9590] AH00163: Apache/2.4.18 (Ubuntu) mod_perl/2.0.9 Perl/v5.22.1 configured -- resuming normal operations
[Sat Apr 23 01:39:08.685938 2016] [core:notice] [pid 9590] AH00094: Command line: '/usr/sbin/apache2'
Your Apache with php7.0 should now be properly configured.
I got this problem as well.
It helped me to delete all PHP and reinstall php7.
All that was needed was:
sudo apt-get purge php*
php7 will be deleted, afterwards just to reinstall:
sudo apt-get install php7.0-mysql php7.0-curl php7.0-json php7.0-cgi php7.0 libapache2-mod-php7.0
Im my case not only the php wasn't working but phpmyadmin aswell i did step by step like that
sudo apt install php libapache2-mod-php
sudo apt install php7.0-mbstring
sudo a2dismod mpm_event
sudo a2enmod mpm_prefork
service apache2 restart
And then to:
gksu gedit /etc/apache2/apache2.conf
In the last line I do add Include /etc/phpmyadmin/apache.conf
That make a deal with all problems
The solution I found for this problem was the default PHP.INI setting for short_open_tag. By default this is set to 'Off'. My PHP code started with
<?
instead of
<?php
If enabled the short_open_tag (by changing 'Off' to 'On' in my php.ini) and reset the apache server (sudo service apache2 restart) and PHP popped back alive.
https://wiki.archlinux.org/index.php/Apache_HTTP_Server
sudo a2dismod mpm_event
sudo a2enmod mpm_prefork
service apache2 restart
Note: The above is required, becauselibphp7.soincluded withphp-apachedoes not work withmod_mpm_event, but will only workmod_mpm_preforkinstead. (FS#39218)Otherwise you will get the following error:
Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP. AH00013: Pre-configuration failed httpd.service: control process exited, code=exited status=1As an alternative, you can use
mod_proxy_fcgi(see Using php-fpm and mod_proxy_fcgi below).
I, too, could run php scripts successfully from the command line on Ubuntu 16.04, but not in any browser. In an attempt to solve the problem I purged my existing copies of both php7.0 and apache2. Thereafter I reinstalled both from the command line including as well as apache2's php library. Frustration followed when I attempted to run "a2enmod php7.0," which informed me that the php7.0 module didn't exist despite the fact that once again I was able to run php scripts from the command line. The instinct kicked in. Opening up Synaptic, I discovered that when I installed the apache2 php library from the command line, I installed only libapache2-mod-php7.0, and had forgotten also to install the "wrapper," libapache2-mod-php, without which the former will not function.
