Apache Update Procedure Check for Apache Installation - ----------------------------- To determine if the Apache web server from HP is installed on your system, use Software Distributor's swlist command. All three revisions of the product may co-exist on a single system. For example, the results of the command swlist -l product | grep -i apache hpuxwsAPACHE B.2.0.52.00 HP-UX Apache-based Web Server Stop Apache - ----------------------------- Before updating, make sure to stop any previous Apache binary. Otherwise, the previous binary will continue running, preventing the new one from starting, although the installation would be successful. After determining which Apache is installed, stop Apache with the following commands: for hpuxwsAPACHE: /opt/hpws/apache[32]/bin/apachectl stop Download and Install Apache - ----------------------------- - Download Apache from Software Depot: <http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do? productNumber=HPUXWSATW213> - Verify successful download by comparing the cksum with the value specified on the installation web page. - Use SD to swinstall the depot. Installation of this new revision of HP Apache over an existing HP Apache installation is supported, while installation over a non-HP Apache is NOT supported. Removing Apache Installation - ---------------------------- If you prefer to remove Apache from your system instead of installing a newer revision to resolve the security problem, use both Software Distributor's "swremove" command and also "rm -rf" the home location as specified in the rc.config.d file "HOME" variables. %ls /etc/rc.config.d | grep apache hpapache2conf hpws_apache[32]conf MANUAL ACTIONS: Yes - Update plus other actions Install the revision of the product.
