we have to rename the extracted directory

linuxhelp ~ # ls master.zip  processwire-master linuxhelp ~ # mv processwire-master/ processwire

Here to change the ownership and permission of the file

linuxhelp ~ # chown -R www-data:www-data processwire/
linuxhelp ~ # chmod -R 775 processwire/

we have to move the processwire directory into the /html location

linuxhelp ~ # mv processwire/ /var/www/html/

Now we have to create a new virtualhost configuration to accessing the Processwire CMS application

linuxhelp ~ # cd /etc/apache2/sites-available/
linuxhelp sites-available # vim process.conf
< VirtualHost \*:80> 
ServerName www.linuxhelp1.com
DocumentRoot /var/www/html/processwire/
< Directory /var/www/html/processwire/> 
AllowOverride All
allow from all
< /Directory> 
< /VirtualHost> 

Now we have to enable the site access

linuxhelp sites-available # a2ensite process.conf 
Enabling site process.
To activate the new configuration, you need to run:
  service apache2 reload
we have to entry to the host file:
linuxhelp sites-available # vim /etc/hosts
Then we need to restart the apache2 service
linuxhelp sites-available # systemctl restart apache2.service
