ELK<\/a> is the most popular log aggreration and analysis stack. ELK stands for Elasticsearch, Logstash and Kibana.<\/p>\n

Elasticsearch – It is a NoSQL, analytics and search engine.<\/p>\n

Logstash – It is a log aggregation tool.<\/p>\n

Kibana – It is a dashboarding tool.<\/p>\n

ELK stack on Amazon EC2<\/h2>\n

This guide will walk you through setting up a test ELK stack on amazon ec2 Ubuntu 14.04 instance. Follow the steps given below to have a working ELK stack.<\/p>\n

Note: I assume that you have a ubuntu 14.04 server up and running in a public subnet.<\/p>\n

    \n
  1. Login and update the server.<\/li>\n<\/ol>\n
    sudo apt-get update<\/code><\/pre>\n
      \n
    1. ELK stack need openjdk. Install it using the following command.<\/li>\n<\/ol>\n
      sudo apt-get install openjdk-7-jre-headless<\/code><\/pre>\n
      3. Chef the jdk installion by checking its verison.<\/p>\n
      java -version<\/code><\/pre>\n
      Installing Elasticsearch<\/h2>\n
      4. Add the elasticsearch repository using the following command.<\/p>\n
      wget -qO - https:\/\/packages.elastic.co\/GPG-KEY-elasticsearch | sudo apt-key add -<\/code><\/pre>\n
      5. Elasticsearch key has to be added to the list using the following command.<\/p>\n
      echo \"deb http:\/\/packages.elastic.co\/elasticsearch\/1.7\/debian stable main\" | sudo tee -a \/etc\/apt\/sources.list.d\/elasticsearch-1.7.list<\/code><\/pre>\n
      6. Update the server<\/p>\n
      sudo apt-get update<\/code><\/pre>\n
      7. Install elasticsearch using the following command.<\/p>\n
      sudo apt-get install elasticsearch<\/code><\/pre>\n
      8. Execute the following command to start the elasticsearch server.<\/p>\n
      sudo service elasticsearch start<\/code><\/pre>\n
      9. Test the elasticsearch service using curl<\/p>\n
      curl localhost:9200<\/code><\/pre>\n
      The output should look like the following.<\/p>\n
      {\n  \"status\" : 200,\n  \"name\" : \"Merlin\",\n  \"cluster_name\" : \"elasticsearch\",\n  \"version\" : {\n    \"number\" : \"1.7.3\",\n    \"build_hash\" : \"05d4530971ef0ea46d0f4fa6ee64dbc8df659682\",\n    \"build_timestamp\" : \"2015-10-15T09:14:17Z\",\n    \"build_snapshot\" : false,\n    \"lucene_version\" : \"4.10.4\"\n  },\n  \"tagline\" : \"You Know, for Search\"\n}<\/code><\/pre>\n
      Installing and setting up Logstash<\/h2>\n
      1. Add logstash to the list. <\/p>\n
      echo \"deb http:\/\/packages.elasticsearch.org\/logstash\/1.5\/debian stable main\" | sudo tee -a \/etc\/apt\/sources.list<\/code><\/pre>\n
      2. Update the server.<\/p>\n
      sudo apt-get update<\/code><\/pre>\n
      3. Install logstash.<\/p>\n
      sudo apt-get install logstash<\/code><\/pre>\n
      4. Update the server.<\/p>\n
      sudo apt-get update<\/code><\/pre>\n
      5. Start and check the status of logstash using the following commands.<\/p>\n
      sudo service logstash start\nsudo service logstash status<\/code><\/pre>\n
      Since it is a single host installation, we will direct all our logs to logstash using a configuration file.<\/p>\n
      6. create a file named \/etc\/logstash\/conf.d\/logstash-syslog.conf and copy the following contents on to the file.<\/p>\n
          input {\n    file {\n    type => \"syslog\"\n    path => [ \"\/var\/log\/messages\", \"\/var\/log\/*.log\" ]\n    }\n    }\n    output {\n    stdout {\n    codec => rubydebug\n    }\n    elasticsearch {\n    host => \"localhost\" # If you are running elasticsearch in different instance, use #the prive ip instead of localhost.\n    }\n    }<\/code><\/pre>\n
      7. Now, restart the logstash server to make necessary changes.<\/p>\n
      sudo service logstash restart<\/code><\/pre>\n
      Installing and configuring Kibana<\/h2>\n
      1. Download the kibana source file. <\/p>\n
      wget https:\/\/download.elastic.co\/kibana\/kibana\/kibana-4.1.1-linux-x64.tar.gz<\/code><\/pre>\n
      2. Extract the source content<\/p>\n
      tar -xzf kibana<\/code><\/pre>\n
      3. Create a kibana directory under \/opt<\/p>\n
      sudo mkdir -p \/opt\/kibana<\/code><\/pre>\n
      4. Move the extracted folder contents to the \/opt\/kibana directory.<\/p>\n
      sudo mv kibana-4.1.1-linux-x64\/* \/opt\/kibana<\/code><\/pre>\n
      5. Create a service file for startup using the following commands.<\/p>\n
      cd \/etc\/init.d && sudo wget https:\/\/raw.githubusercontent.com\/akabdog\/scripts\/master\/kibana4_init -O kibana4\nsudo chmod +x \/etc\/init.d\/kibana4\nsudo update-rc.d kibana4 defaults 96 9<\/code><\/pre>\n
      6. Start the kibana dashboard service.<\/p>\n
      sudo service kibana4 start<\/code><\/pre>\n
      The above command would start Kibana service on port 5601.<\/p>\n
      Now you can access the Kibana dashboard on 5601 port with the public ip of your instance.<\/p>\n
