How can we set nodetool and cqlsh to be run from anywhere and by any user on linux server

问题

I am trying to setup environment variables so that any user on a particular server can run commands like nodetool or cqlsh from any where in linux file system . The effort to traverse to bin directory everytime should be saved . How can we achieve this ? My DSE 4.8 is a tarball install .

回答1:

• Nodetool is usually available to any user that has execution privileges in your linux boxes
• For cqlsh, you can set any configuration inside the cqlshrc file (usually found in $HOME/.cassandra/cqlshrc; we have used to enable client-node encryption but has more configurable options

回答2:

To setup environment variable just follow some steps from root user:

# vi /etc/profile.d/cassandra.sh

Add the following lines to the cassandra.sh file-

export CASSANDRA_HOME=/opt/apache-cassandra-3.0.8
export CASSANDRA_CONF_DIR=/opt/apache-cassandra-3.0.8/conf

Here /opt/ is my directory, where I've extracted my apache-cassandra-3.0.8-bin.tar.gz tarball.

After adding those lines to cassandra.sh, save and exit. Then-

# source /etc/profile.d/cassandra.sh
