I edited my comment to include the closing quote, sorry about that. </p> http://www.datastax.com/support-forums/topic/opscenter-free-212-will-not-start-on-201203#post-7217 Tue, 30 Oct 2012 18:25:55 +0000 dawookie 7217@http://www.datastax.com/support-forums/ <p>You were right, /etc/redhat-release is not part of the image. After adding the suggested PY_DISTRO and sorting out the missing double quote it is smooth sailing. </p> http://www.datastax.com/support-forums/topic/opscenter-free-212-will-not-start-on-201203#post-7216 Tue, 30 Oct 2012 17:59:09 +0000 thobbs 7216@http://www.datastax.com/support-forums/ <p>I believe the latest Amazon AMIs can cause problems for the distro version detection that OpsCenter does. Can you confirm that <code>/etc/redhat-release</code> does not exist?</p> <p>If it does not, there is a workaround. Edit <code>/usr/share/opscenter/bin/opscenter</code>, and around line 78 (just before <code>export PYTHONPATH=&quot;...&quot;</code>), add the following line:</p> <p><code>PY_DISTRO=&quot;./lib/py-redhat/${PY_VER}/shared/${PY_ARCH}:./lib/py-redhat/${PY_VER}/6/${PY_ARCH}&quot;</code></p> <p>This will hardcode it to use RHEL 6 packages, which I believe should work for the latest Amazon AMIs. </p> http://www.datastax.com/support-forums/topic/opscenter-free-212-will-not-start-on-201203#post-7176 Tue, 30 Oct 2012 00:45:06 +0000 dawookie 7176@http://www.datastax.com/support-forums/ <p>This is on an Amazon m1.medium host using a fairly vanilla AMI based on 2012.03.3 Amazon.
