fall-2020, specifications, webdev.

I ran sudo service apache2 restart and there was an error.

Often this means you have a syntax error or some other configuration issue in your host’s .conf file in /etc/apache2/sites-available. To see what line is causing it, run these two commands:

sudo service apache2 restart; sudo journalctl -xe

There are two commands there, separated by ;. We want to run both commands in quick succession before the logs fill up, making it hard to find the error.

Read the output to figure out what went wrong.
