Simple EK Deployment on 1 CentOS 7 node

Test environment:
EK version: 6.3 (x-pack included)
CentOS 7.2 (kernel 3.10)
2 VCPU, 4GB RAM, 100GB separate blk data storage
Internet Access

BLK device preparation

lsblk ### find out which device will be used for ES data. Let's assume that its sdb fdisk /dev/sdb ### n,p,enter,enter/dev/sdb1 /opt/es-data ext4 defaults 0 0,w mkfs.ext4 /dev/sdb1 ### if you have a bigger disk, like 1 TB, xfs would be a better choice mkdir /opt/es-data vim /etc/fstab
/dev/sdb1 /opt/es-data ext4 defaults 0 0
mount -a

Starting and Enabling Services

systemctl enable elasticsearch systemctl start elasticsearch systemctl enable kibana systemctl start kibana

Create fluentd index

1. Go to kibana url (like 10.220.101.86:5601 in an example)
2. Dev-> console
   PUT fluentd { "settings" : { "index" : { "number_of_shards" : 1, "number_of_replicas" : 0 } } }

That’s it!
