Install Splunk on Ubuntu

Splunk is a popular enterprise level tool for log collection, analysis and management. While you can obtain an enterprise license, most functions are available in the free community edition.

Setup is very easy:

  1. Download and move the .tar.gz file to the appropriate server (i386 vs. amd64)
  2. sudo dpkg -i splunk*.deb
  3. Start the server:

    sudo /opt/splunk/bin/splunk start

    The first time you run after installation or update you will have to accept terms.

  4. Access the admin screen:

    http://HOSTNAME:8000

    login (admin/changeme)
    change password

  5. Go to Settings/Forwarding * Receiving
    – add new (port 9997)
  6. Open firewall port (if enabled):

    sudo ufw allow 8000
  7. Now to start as a service…

    sudo /opt/splunk/bin/splunk enable boot-start

Install Splunk Universal Forwarder on Ubuntu

After a while it can get tedious to access and review server logs via the command line. There are several tools available that can provide the same information in a graphical manner. Recently I’ve migrated to Splunk as there are both Enterprise and Free versions available.

  1. Of course, you’ll need a Splunk server installed first, as the forwarder is really just another (lighter) instance that will forward the log information to a central location.
  2. Download the system appropriate installer from:
    http://www.splunk.com/download/universalforwarder
  3. Check to see if you are running 32 or 64 bit OS.uname -aIf you see i686 you are 32 bit, if x86_64 you are 64 bit!
  4. Download, you’ll likely need a different version:sudo dpkg -i splunkforwarder-6.1.3-220630-linux-2.6-intel.deb
    or
    sudo dpkg -i splunkforwarder-6.1.3-220630-linux-2.6-amd64.deb
  5. Enable auto-start on reboot:cd /opt/splunkforwarder/bin/

sudo ./splunk enable boot-start

    1. Start the server:sudo service splunk start
    2. Set the password:

      The default ‘admin‘ password is ‘changeme‘ so we need to change it immediately to do anything else, or we will see errors in future steps.

      sudo /opt/splunkforwarder/bin/splunk edit user admin -password YOUR_NEW_PASSWORD -auth admin:changeme

    3. Set the server:sudo /opt/splunkforwarder/bin/splunk add forward-server YOUR_SERVER_ADDRESS:9997

      NOTE: if you get prompted for a splunk username/password you likely skipped the above step. Remember – the forwarder is a new ‘light’ installation of the server and as such has it’s own users!

    4. Enable some monitors on the box:Some common services and log locations to get you started…
      Apache2 HTTPd
      sudo /opt/splunkforwarder/bin/splunk add monitor /var/log/apache2 -index main -sourcetype Apache2
      Tomcat7
      sudo /opt/splunkforwarder/bin/splunk add monitor /opt/tomcat7/logs -index main -sourcetype Tomcat7
      MySQL
      sudo /opt/splunkforwarder/bin/splunk add monitor /var/log/mysql -index main -sourcetype MySQL
      Postfix (SMTP)
      sudo /opt/splunkforwarder/bin/splunk add monitor /var/log/mail.log -index main -sourcetype Postfix
      Squid3 (Proxy)
      sudo /opt/splunkforwarder/bin/splunk add monitor /var/log/squid/access.log -index main -sourcetype Squid3
      sudo /opt/splunkforwarder/bin/splunk add monitor /var/log/squid/cache.log -index main -sourcetype Squid3

      SonarQube
      sudo /opt/splunkforwarder/bin/splunk add monitor /opt/sonar/logs -index main -sourcetype Sonar
      PM2
      sudo /opt/splunkforwarder/bin/splunk add monitor /home/{user}/.pm2/logs -index main -sourcetype PM2
      NPM
      sudo /opt/splunkforwarder/bin/splunk add monitor /home/scott/.npm/_logs -index main -sourcetype NPM
  1. (OPTIONAL) Verify configuration by opening file at the following:sudo su
    vi /opt/splunkforwarder/etc/apps/search/local/inputs.conf
    exit
  2. You now should be able to log into your server and see new data flowing from the forwarder.

    NOTE: this requires you to enable ‘receiving’ of data on the port specified above, usually 9997.

RabbitMQ setup on Ubuntu

In my past enterprise experience, I’ve worked a lot with IBM WebSphere MQ, as I’ve evolved to open source, I’ve found RabbitMQ to fill my messaging needs as an implementation of AMPQ. While I’ve added Ubuntu installation instructions here, server and API implementations are available for most programming languages and operating systems.

NEW WAY:

sudo apt-get install rabbitmq-server

OLDER RELEASES:

sudo wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc

sudo apt-key add rabbitmq-signing-key-public.asc

sudo vim /etc/apt/sources.list.d/rabbit.list

NOTE: this file will probably be empty, just add the following line (for Ubuntu 11.04 and earlier)


deb http://www.rabbitmq.com/debian/ testing main


sudo apt-get update
sudo aptitude install rabbitmq-server
