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
versions products 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://software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPUXWSATW211>
 
- 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 version 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 version 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 - NonUpdate
Install the product containing the fix.
 
HP-UX B.11.22  requires upgrading to HP-UX B.11.23.
