Big Data ES Series--The first ElasticSearch2.2 cluster installation deployment

First part Installation Preparation

Prepare three host nodes:

Hc11.spads 192.168.160.181

Hc12.spads 192.168.160.182

Hc13.spads 192.168.160.183

To prepare the package:

Elasticsearch-2.2.0.tar.gz

Note: Upload the above packages to each host node/opt/softwareres/directory.

Part II installation Configuration elasticsearch-2.2.0

1, each host node decompression package elasticsearch-2.2.0.tar.gz

tar–zxvf/opt/softwareres/elasticsearch-2.2.0.tar.gz–c/opt/

ll/opt/| grep elastic

2. Modify the configuration

Each host node edits the ELASTICSEARCH.YLM configuration file separately

Vim/opt/elasticsearch-2.2.0/config/elasticsearch.ylm

Note: YLM file specification:

(1) The line needs shelf write, the beginning of the row is not allowed to have spaces

(2) you need a space after the colon

Where you need to configure the following

(1) Cluster Specify the cluster name ( each host node configuration must be consistent )

Cluster.name:hc

(2) node name ( different host node configuration required )

Node.name:node-1

(3) Network specified IP address and HTTP access port

network.host:192.168.160.181 ( IP for each host node)

HTTP.PORT:9200 ( consistent with each host node )

(4) Other configuration-anti-brain crack parameters ( each host node configuration consistent )

Discovery.zen.ping.multicast.enabled:false ( turn off default multicast )

Discovery.zen.ping_timeout:120s

client.transport.ping_timeout:60s

Discovery.zen.ping.unicast.hosts: ["192.168.160.181", "192.168.160.182", "192.168.160.183"] ( limit matching host node )

(5) Add user to each host node and grant permission to switch the login user to the new user

Note: Elasticsearch does not allow root user to start, all need to add normal user to start Elasticsearch.

Useradd Bigdata

passwd Bigdata

Follow the prompts to repeat the password two times to complete the new user.

Chown–r bigdata:bigdata/opt/elasticsearch-2.2.0/

Complete the authorization.

Su Bigdata

Switch to normal user.

(6) Start Elasticsearch

Each host node executes commands

/opt/elasticsearch-2.2.0/bin/elasticsearch

Then open the browser http://hc11.spads:9200 (directly using the hostname and need to configure hosts) to view the cluster status.
