Apache¶
Configuration¶
See https://httpd.apache.org/docs/current/configuring.html

Editing apache2.conf¶
Note that sudo apachectl configtest can be used to test configuration files for syntax errors. Omitting the sudo might result in an syntax error being reported (presumably because the test can not run properly as some files may need to be accessed that can only be accessed with sudo. If all is well you should see: Syntax OK.
Apache directives can be seen at https://httpd.apache.org/docs/current/mod/directives.html
To prevent Apache listing the contents of directories I modified the Indexes directive. First vim /etc/apache2/apache2.conf* then search for Indexes. This showed:
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
The word Indexes was edited to read -Indexes, and the word FollowSymLinks was edited to read +FollowSymLinks. A comment was made and the file saved. Now this part of apache2.conf looks like this:
<Directory /var/www/>
# I added the - and + on the next line:
Options -Indexes +FollowSymLinks
AllowOverride None
Require all granted
</Directory>
Note that it is a syntax error to mix options which are preceeded by a - or + with options which are not. That is why I had to put a + in front of FollowSymLinks. See https://httpd.apache.org/docs/2.4/mod/core.html#options for more information on this issue and also on the Options directive generally.
It is necessary to restart Apache in order for configuration changes to be applied.
