安装PHP7后，Apache2仍在运行PHP5

Question

I set up a apache2 server, and it was running PHP5. I have followed this guide to install PHP7: https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-php-7-on-ubuntu-14-04

Now, when I run php -v I get:

PHP 7.0.30-1+ubuntu14.04.1+deb.sury.org+1 (cli) (built: May  2 2018 13:00:43) ( NTS )

However, when I made a webpage on apache and echoed phpinfo(), I got:

PHP Version 5.5.9-1ubuntu4.24

How can I tell apache2 to use PHP7?

Answer 1

php -v gives you the version of php-cli, to enable it in apache2 you have to run these commonads

sudo a2dismod php5
sudo a2enmod php7.0
sudo service apache2 restart

then check phpinfo() for the version. it should change.

Answer 2

reading more in depth the article, many people said to encouter difficulties when running $sudo apt-get install php7.0 because of "unmet dependencies". Execute the following $sudo apt-get install libapache2-mod-php7.0 php7.0-mysql php7.0-curl php7.0-json to be sure yoo have everything needed. Good luck!

You installed new version of php for your apache2 but you will need to disable/remove sym-links to old php5.x and enable/add sym-links for new php7.x. @Rhythm Shahriar pointed that out.

But here is the full steps taken and edited from https://askubuntu.com/questions/760907/upgrade-to-16-04-php7-not-working-in-browser

To configure php7.x to run with your apache2 server you need to do some configuration:

1. Make sure you remove any traces of php/php5.x

cd /etc/apache2/mods-enabled
ls -la

The output should not contain any php5.x.conf or php5.x.load , but if it does, do the following:

# this is the proper way of disabling modules
sudo a2dismod php5.x

# run this only if the above command didn't remove the php5.x sym-links
sudo rm php5.x.load
sudo rm php5.x.conf

Now add the php7.x.conf and php7.x.load instead:

# this is the proper way of enabling modules
sudo a2enmod php7.x

# run this only if the above command didn't create the php7.x sym-links
sudo ln -s php7.x.conf ../mods-available/php7.x.conf
sudo ln -s php7.x.load ../mods-available/php7.x.load

The output of ls -la php* should look like this:

lrwxrwxrwx 1 root root 29 Apr 15 03:55 php7.x.conf -> ../mods-available/php7.x.conf
lrwxrwxrwx 1 root root 29 Apr 15 03:55 php7.x.load -> ../mods-available/php7.x.load

After dealing with the modules we now come to the /etc/apache2/conf-enabled directory. Remove any traces of php/php5.x here as well by sudo rm <name>

Then, if needed do:

# the proper way of enabling configs
sudo a2enconf php7.x-cgi
sudo a2enconf php7.x-fpm

# do those commands only if the above didn't work out
sudo ln -s php7.x-cgi.conf ../conf-available/php7.x-cgi.conf
sudo ln -s php7.x-fpm.conf ../conf-available/php7.x-fpm.conf

The output of ls -la php* should look like this:

lrwxrwxrwx 1 root root 33 Apr 21 17:00 php7.x-cgi.conf -> ../conf-available/php7.x-cgi.conf
lrwxrwxrwx 1 root root 33 Apr 21 17:01 php7.x-fpm.conf -> ../conf-available/php7.x-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 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

Then 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.x should now be properly configured. Tested working on Ubuntu 16.04 upgraded from php5.6 to latest as of today php7.3
