在Ubuntu信任机器上重新安装Cassandra

Question

I'm trying to install Cassandra 3.4 on 64 bit ubuntu 14.04. I followed the DataStax instructions

• Java installation
• Cassandra installation

Everything seems to be going alright, but when checking if cassandra is up with nodetool status I get:

vagrant@vagrant-ubuntu-trusty-64:~$ nodetool status
nodetool: Failed to connect to '127.0.0.1:7199' - ConnectException: 'Connection refused'.

Is there something missing in the instruction?

Answer 1

You need to check log files to find the errors.

use

sudo find / -name "cassandra.log" and sudo find / -name "system.log"

to find what errors are mentioned there.

Then use sudo service cassandra restart

Edit : Since, cassandra.log doesn't exists, I have to assume, cassandra never got initialized.

That is why it says "Directory /var/lib/cassandra/data doesn't exist"

Lets take it step by step

1. do sudo chmod 777 /var/lib/cassandra
2. do sudo mkdir /var/lib/cassandra/data /var/lib/cassandra/commitlog
3. do chown cassandra:cassandra /var/lib/cassandra/data
4. do chown cassandra:cassandra /var/lib/cassandra/commitlog

And install Oracle jdk 1.8 instead of using openjdk. Then restart the service.
