I've made a note to look into better libssl support. We'll be sure to update this topic if something changes.

Actually symlinking worked for previous versions of libssl. Anyway, with libssl1.0.0e on Ubuntu 11.10 it works while with libssl 1.0.1-4ubuntu3 on Ubuntu 12.04 doesn't. Forcing Ubuntu 12.04 to use the bugged version libssl 0.9.8 OpsCenter starts. Is there any chance to make OpsCenter work with any libssl>0.9.8? Thank you -- antonio mbulman on "OpsCenter, Ubuntu 12.04 64bit and libssl and libcrypto" http://www.datastax.com/support-forums/topic/opscenter-ubuntu-1204-64bit-and-libssl-and-libcrypto#post-1848 Fri, 04 May 2012 15:44:54 +0000 mbulman 1848@http://www.datastax.com/support-forums/ Symlinking won't work, you'll need to install libssl 0.9.8. You should be able to do this via: apt-get install libssl0.9.8 Anonymous on "OpsCenter, Ubuntu 12.04 64bit and libssl and libcrypto" http://www.datastax.com/support-forums/topic/opscenter-ubuntu-1204-64bit-and-libssl-and-libcrypto#post-1845 Fri, 04 May 2012 14:25:55 +0000 Anonymous 1845@http://www.datastax.com/support-forums/ Hello, everything fine on Ubuntu 11.10 64bit.

You'll need to change the steps that nehc gave to be: 1) Install openssl 0.9.8 sudo yum install openssl098e-0.9.8e-17.7.amzn1.x86_64 2) Change to /usr/lib64 and manually create following two symbolic links: sudo ln -s libssl.so.0.9.8e libssl.so.0.9.8 sudo ln -s libcrypto.so.0.9.8e libcrypto.so.0.9.8 Anonymous on "Issue starting opscenterd service" http://www.datastax.com/support-forums/topic/issue-starting-opscenterd-service#post-866 Mon, 19 Dec 2011 08:19:01 +0000 Anonymous 866@http://www.datastax.com/support-forums/ I have followed the steps given by nehc ,but having the same issue in Amazone AMI ./src/lib/python2.6/site-packages:./lib/py:./lib/py-debian/2.6/amd64: Traceback (most recent call last): File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 631, in run runApp(config) File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/scripts/twistd.py", line 23, in runApp _SomeApplicationRunner(config).run() File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 374, in run self.application = self.createOrGetApplication() File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 439, in createOrGetApplication application = getApplication(self.config, passphrase) --- <exception caught here> --- File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 450, in getApplication application = service.loadApplication(filename, style, passphrase) File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/service.py", line 400, in loadApplication application = sob.loadValueFromFile(filename, 'application', passphrase) File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/persisted/sob.py", line 210, in loadValueFromFile exec fileObj in d, d File "bin/start_opscenter.py", line 1, in <module> from opscenterd import opscenterd_tap File "build/lib/python2.6/site-packages/opscenterd/opscenterd_tap.py", line 16, in <module> File "build/lib/python2.6/site-packages/opscenterd/Config.py", line 392, in init_config File "build/lib/python2.6/site-packages/opscenterd/events/plugins/CassandraStore.py", line 12, in <module> File "build/lib/python2.6/site-packages/opscenterd/CassandraService.py", line 17, in <module> File "build/lib/python2.6/site-packages/opscenterd/Cluster.py", line 14, in <module> File "build/lib/python2.6/site-packages/opscenterd/AgentServer.py", line 23, in <module> File "build/lib/python2.6/site-packages/opscenterd/HttpUtils.py", line 10, in <module> File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/OpenSSL/__init__.py", line 11, in <module> import rand, crypto, SSL, tsafe exceptions.ImportError: libssl.so.0.9.8: cannot open shared object file: No such file or directory Failed to load application: libssl.so.0.9.8: cannot open shared object file: No such file or directory nickmbailey on "pycassa.pool.MaximumRetryException: Retried 6 times." http://www.datastax.com/support-forums/topic/pycassapoolmaximumretryexception-retried-6-times#post-860 Thu, 15 Dec 2011 20:18:21 +0000 nickmbailey 860@http://www.datastax.com/support-forums/ This appears to be a normal Unavailable Exception.

In which version of the OpsCenter was it resolved? I still had the same problem with v1.3.1. But thanks for the posts here for providing clues.
