When I launch it with sudo /etc/init.d/dse start it seems to work. It returns:

Starting DSE daemon dse
DSE daemon starting with Hadoop and Solr disabled (edit /etc/default/dse to enable)

But when I try to connect to the tutorial "Test Cluster" (so localhost) with opscenter (on a distant machine but with port 8888 shared), I got this error:

Error creating cluster: Unable to connect to cluster

And if I check the health of dse with sudo /etc/init.d/dse status: I got:

dse dead but pid file exists

The console or /var/log/cassandra/output.log will likely contain something like this (where nodename1 is whatever you named your node):

Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: nodename1: nodename1

Same as https://stackoverflow.com/questions/7496640/problem-on-starting-cassandra, basically you need to make sure that the hostname you are using can be resolved (by putting it into /etc/hosts).
