vocabulary

“httpd” is a synonym for “the Apache server in linux.” It stands for “http daemon,” which is a piece of software that is always running in the background, watching and waiting for requests made through the http:// protocol. Apache is just one flavor of httpd, but it is extremely popular and successful.

/var/www/html

This is the document root–where all browser-accessible files are kept. When someone puts http://tighar.org into their browser, they arrive at /var/www/html/ on our system. Their browser cannot access anything above that folder.

chown apache:apache html
chmod -R 775 html
