linux-installer

Self-extracting installer used to install cassandra-diagnostics.

Dependencies

This installer should run on any fairly modern linux distribution.

Requirements for running installer script:

  • bash 4.x
  • GNU Awk 4.x
  • getopt, enhanced version
  • readline
  • wget
  • mktemp

Requirements for building installer script:

  • cat
  • tar
  • gzip

Usage

First checkout bash-installer and put it on Cassandra node where you want to install Cassandra diagnostics.

Prepare cassandra-diagnostics.yml (most basic configuration file can be seen on this link and some examples are in core module readme.

Run cassandra-diagnostics-installer.sh shell script with following switches:

  • -c, --cassandra-conf-dir - location of Cassandra configuration directory
  • -l, --cassandra-lib-dir - location of Cassandra library directory
  • -v, --cassandra-version - installed Cassandra version number (e.g 3.0.12, 2.1.4, etc.)
  • -V, --cassandra-diagnostics-version - desired version of cassandra-diagnostics
  • -C, --cassandra-diagnostics-conf-file - location of cassandra-diagnostics configuration (YAML) file
  • -h, --help - show help message

All parameters except "-h, --help" are mandatory.

When invoked with all of mandatory parameters, installer will extract itself to /tmp/cassandra-diagnostics-installer.XXXXXX (XXXXXX is random alphanumeric string), and execute main.sh script, which will carry on the installation.

Here is example of command sudo ./cassandra-diagnostics-installer.sh -c /etc/cassandra/ -l /usr/share/cassandra/lib/ -v 3.0.12 -V 1.4.6 -C ./cassandra-diagnostics.yml.

Building self-extracting installer script

Run build-installer.sh. It will tar and gzip scripts from installer directory, and append it at the end of installer-runner.sh, producing cassandra-diagnostics-installer.sh script.
