Starting Cassandra on Linux

Upon installing and configuring Cassandra on your machine, you can start Cassandra. 

How to start Cassandra on Linux

1. Start Cassandra using the following command:

   $ sudo service cassandra start 
   
   

2. Issue the following command to verify that Cassandra is ready:

   $ tail /var/log/cassandra/cassandra.log 

    

3. Verify that the command prompt contains a line similar to the following example:
   

   INFO 15:51:58,644 Node/10.1.1.123 state jump to normal

   INFO 15:51:58,650 Waiting for gossip to settle before accepting client requests... 

   INFO 15:52:06,650 No gossip backlog; proceeding

    

4. If you get an out of memory error when starting Cassandra (Figure 1) you need to open the file /etc/cassandra/conf/cassandra-env.sh 

   and increase the Java stack size from JVM_OPTS="$JVM_OPTS -Xss180k" to JVM_OPTS="$JVM_OPTS -Xss228k" (Figure 2).
