Since it sounds like OpsCenter is running on your local network, you will need to disable any proxies set up in your web browser.</p> <p>For mor information on installing and configuring OpsCenter see <a href="http://www.datastax.com/docs/opscenter/index" rel="nofollow">http://www.datastax.com/docs/opscenter/index</a> </p> http://www.datastax.com/support-forums/topic/to-check-if-opscenter-start-or-not#post-665 Sat, 12 Nov 2011 05:36:55 +0000 Anonymous 665@http://www.datastax.com/support-forums/ <p>Oh, I can start Opscenter now, I put all my interfaces down and use no proxy on Firefox, then I open terminal and type in<br /> service opscenterd start &amp;</p> <p> then</p> <p>service opscenterd start</p> <p> then the terminal tell me that service opscenterd start, I go to firefox and type in </p> <p>192.168.1.99:8888</p> <p>so the Opscenter load now, Is it the right way to start Opscenter daemon ? </p> http://www.datastax.com/support-forums/topic/to-check-if-opscenter-start-or-not#post-653 Fri, 11 Nov 2011 15:46:19 +0000 nickmbailey 653@http://www.datastax.com/support-forums/ <p>Did you restart the opscenter process after changing the config file? The process will need to be restarted after any configuration changes.</p> <p>If that does not fix the problem, are there any errors in the opscenter log? That will be located at /var/log/opscenter/opscenterd.log or at ./log/opscenterd.log depending on whether you installed opscenter using the debian package or the tarball download. </p> http://www.datastax.com/support-forums/topic/to-check-if-opscenter-start-or-not#post-650 Fri, 11 Nov 2011 03:17:23 +0000 Anonymous 650@http://www.datastax.com/support-forums/ <p>I have installed Opscenter free version on Ubuntu 10.04, I have Apache Cassandra cluster installed on this PC too with my PC is a host and two clients by using Virtualbox , then I configured opscenterd.conf file like this </p> <pre><code>[jmx] # The default jmx port for Cassandra &gt;= 0.8.0 is 7199. If you are using # Cassandra 0.7.*, the default is 8080, and you should change this to # reflect that. port = 7199 [webserver] port = 8888 interface = 192.168.1.99 [logging] # level may be TRACE, DEBUG, INFO, WARN, or ERROR #level = INFO [cassandra] # a comma-separated list of places to try for a connection to your Cassandra # cluster: seed_hosts = 192.168.1.99</code></pre> <p> the ip address 192.168.1.99 is my seed node, when I type in my web browser 192.168.1.99:8888 this page can not load :<br /> <pre><code>Unable to connect Firefox can&#039;t establish a connection to the server at 192.168.1.99:8888.</code></pre> <p>thank you for your helps </p>
