Kibana4 apache configuration with authentication

We need to configure httpd to listen on port 80 which does a reverse proxy to localhost on 5601.

Make sure kibana is listening only on internal port before this settings are done .

        ServerAdmin devops@learnadmin.com

        ServerName kibana.learnadmin.com

        DocumentRoot /var/www/auth

       

            AuthType Basic

            AuthName "Authentication Required"

            AuthUserFile "/var/www/auth/htpasswd"

            Require valid-user

       

        ProxyPass / http://localhost:5601/

        ProxyPassReverse / http://localhost:5601/

Use below command to create a htpasswd file and enable authentication 

htpasswd -c /var/www/auth/htpasswd devops

Monitoring of kibana and logstash services and start them if process not found

Kibana and logstash might run out of memory and application might get closed or get terminated. In that case we will be running the below script to monitor services and start them if not running .

There are other parameters that need to be verified before going for this option like java heap size etc.

#!/bin/bash

LOGSTASH=logstash

KIBANA=kibana

var1=`ps -ef|grep -i $LOGSTASH|sed -e '/grep/d'`

if [ -z "$var1" ]; then

nohup /opt/logstash/bin/logstash -f /etc/logstash/conf.d/logstash.conf &

echo "Process logstash not found" | mail -s "Process logstash not found creating a new one" devops@learnadmin.com

else

echo "process logstash  found."

fi

var2=`ps -ef|grep -i $KIBANA|sed -e '/grep/d'`

if [ -z "$var2" ]; then

nohup /opt/kibana/bin/kibana status &

echo "Process kibana  not found" | mail -s "Process kibana not found creating a new one" devops@learnadmin.com

else

echo "process kibana found."

fi
