Administrative Tasks

   ## Elasticsearch on 64 bit Linux now uses mmapfs by default. 
   ## Make sure that you set MAX_MAP_COUNT to a sufficiently high number.
   ## The RPM and Debian packages default this value to 262144.
   11  sysctl vm.max_map_count
   12  curl http://localhost:9200/_nodes/process?pretty
       {
         "cluster_name" : "...",
         "nodes" : {
           "hHZH7A4jS2qxBiMByJBSaA" : {
             "name" : "Myron MacLain",
             "transport_address" : "inet[/xx.xxx.xx.xx:xxxx]",
             "host" : "elasticsearch-1-1.c.xxx-xxx-xxx.internal",
             "ip" : "xx.xxx.xx.xx",

Secure with nginx

2. https://www.digitalocean.com/community/tutorials/how-to-set-up-http-authentication-with-nginx-on-ubuntu-12-10

Add Kibana

Reference: https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-4-on-ubuntu-14-04

1. Install Kibana

cd ~/
wget https://download.elastic.co/kibana/kibana/kibana-4.1.2-linux-x64.tar.gz

vi ./kibana-4.1.2-linux-x64/config/kibana.yml
# In the Kibana configuration file, find the line that specifies host,
# and replace the IP address ("0.0.0.0" by default) with "localhost":
# host: "localhost"

mkdir -p /opt/kibana
cp -R kibana-4.1.2-linux-x64/* /opt/kibana/

2. Tweak the nginx proxy so that all requests from /kibana are served by the kibana server and not the original elasticsearch server:

3. vi /etc/nginx/sites-available/default

4. Sample:

     location / {
       ...
       proxy_pass          http://localhost:9200;
       ...
     }
   
     # `/kibana/` is used instead of `/kibana` to make this work
     # so don't remove it willy-nilly
     location /kibana/ { 
       ...
       proxy_pass          http://localhost:5601/;
       proxy_redirect      http://localhost:5601 https://YOUR_SUBDOMAIN.YOUR_DOMAIN.com/kibana;
       ...
     }
   

5. test and reload

   /etc/init.d/nginx configtest /etc/nginx/sites-available/default
   service nginx restart
