In other installations, such as Redhat or CentOS, apache or apache2 is referred to as HTTPD in binary / executables, configuration files, commands, etc. | In other installations, such as Redhat or CentOS, apache or apache2 is referred to as HTTPD in binary / executables, configuration files, commands, etc. | ||

For Redhat / CentOS / RockyOS and similar users who are used to having HTTPD stuff located in /var/www/html by default, below are some commands to put in the Startup of OpenWRT to make Apache stuff easier to find (if you're on 'auto pilot'); | |||
* mkdir /tmp/www | |||
* ln -s /usr/share/apache2/htdocs /var/www/html | |||
* ln -s /usr/share/apache2/cgi-bin /var/www/cgi-bin | |||
* ln -s /usr/share/apache2/error /var/www/error | |||
* ln -s /usr/share/apache2/icons /var/www/icons | |||
...and the reason it's in startup is because the VAR Directory in OpenWRT is actually the TMP Directory (IE, VAR is a softlink / shortcut to TMP), so it disappears after rebooting. | |||
Firewall: Open ports on the firewall if public availability is desired. | |||

As noted previously, but worth mentioning again, OpenWRT names the interactive command line interface for PHP ''php-cli''. Most sites give examples that use the command ''php'', so to make it easier create a symbolic link with this command: ln -s /usr/bin/php-cli /usr/bin/php | As noted previously, but worth mentioning again, OpenWRT names the interactive command line interface for PHP ''php-cli''.
