How to install and configure Apache on openSUSE or SLES
SUSE Linux Enterprise Server or SLES is the recommended version of SUSE for server deployment though the installation and related documentation are not as polished as other major Linux distributions.
Apache webserver can be installed on both openSUSE and SLES using zypper from the command line. It requires further configuration before being usable as the installer package does not automatically configure some of the options like other major Linux distributions.
Steps to install and configure Apache on openSuSe or SLES:
Launch terminal application.
Refresh zypper package list.
> sudo zypper refresh [sudo] password for root: Repository 'Main Repository (NON-OSS)' is up to date. Repository 'Main Repository (OSS)' is up to date. Repository 'Main Update Repository' is up to date. Repository 'openSUSE-20191225-0' is up to date. All repositories have been refreshed.
