2.2. Required Programs, Dependencies, and Configuration
To install any Red Hat Certificate System subsystems on Red Hat Enterprise Linux, three programs
are required: OpenJDK, Apache or Tomcat (depending on the subsystem), and Red Hat Directory
Server. All other require packages should be present as part of the base Red Hat Enterprise Linux
operating system packages.
2.2.1. Java Development Kit (JDK)
Certificate System requires OpenJDK 1.6.0. On Red Hat Enterprise Linux systems, this must be
installed separately. The OpenJDK can be installed by using
yum
or by downloading the packages
directly from
http://openjdk.java.net/install/
. For example:
yum install java-1.6.0-openjdk
After installing the JDK, run
/usr/sbin/alternatives
as
root
to insure that the proper JDK is
available:
/usr/sbin/alternatives --config java
There are 3 programs which provide 'java'.
Selection Command
-----------------------------------------------
1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java
2 /usr/lib/jvm/jre-1.6.0-openjdk/bin/java
*+ 3 /usr/lib/jvm/jre-1.6.0-sun.x86_64/bin/java
See
http://kbase.redhat.com/faq/FAQ_54_4667.shtm
for more information on using the JDK for Red
Hat Certificate System.
2.2.2. Apache
Apache 2.x must be installed in order to install the TPS subsystem. Check that the appropriate version
of Apache is installed.
