sudo a2dismod php5 sudo a2enmod php5.6 sudo service apache2 restart
Cheers
tail -f /var/log/apache2/access.log
Apache can be a bit picky with *:80 at times, so you might want to try 8.8.8.8:80 instead to see if it works better. Run
apachectl -t -D DUMP_VHOSTS
to see how Apache parses your configuration files.
Sometimes you may want to specify a combination of distinct authenticator and installer plugins. To do so, specify the authenticator plugin with --authenticator or -a and the installer plugin with --installer or -i.
For instance, you could create a certificate using the webroot plugin for authentication and the apache plugin for installation.
certbot run -a webroot -i apache -w /var/www/html -d example.com

1) Update your packages:
sudo apt-get update
2) Install the curl utility:
sudo apt-get install curl
3) Download the installer:
sudo curl -s https://getcomposer.org/installer | php
4) Move the composer.phar file:
sudo mv composer.phar /usr/local/bin/composer
5) Use the composer command to test the installation. If Composer is installed correctly, the server will respond with a long list of help information and commands:
user@localhost:~# composer

# echo "" > access.log OR # echo > access.log
Note: You should keep in mind that an empty string is not the same as null. A string is already an object much as it may be empty while null simply means non-existence of an object.
For this reason, when you redirect the out of the echo command above into the file, and view the file contents using the cat command, is prints an empty line (empty string).
To send a null output to the file, use the flag -n which tells echo to not output the trailing newline that leads to the empty line produced in the previous command.
# echo -n "" > access.log
Everyone experiencing this issue should execute these commands:
sudo usermod -aG www-data $USER
Adds the currently logged in user to the www-data group.
sudo chown -R www-data:www-data /var/www
Changes the ownership of the /var/www directory to www-data group.
sudo chmod -R 755 /var/www
If this doesn’t fix the issue you’re having, you’ve got something else wrong and bashing DO is not going to help anyone. If you want a managed server, look for hosting elsewhere. If you need help, ask someone or hire an admin that knows how to not only ‘set things up’ but knows how to secure your server as well. You’ll be glad you did. DO is not for novices, even if they have a lot of tutorials.
