ubuntu 上安裝 Elasticsearch Cluster

1. 參考 Installing ElasticSearch on Ubuntu 14.04 ，分別在欲加入 Elasticsearch Cluster 的每部機器上完成安裝

### Install  Oracle Java (改安裝 Oracle Java)

cd /tmp

sudo apt-get install python-software-properties

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

 

### Download and Install ElasticSearch ver 1.3.2

### Check http://www.elasticsearch.org/download/ for latest version of ElasticSearch and replace wget link below

wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.3.2.deb

sudo dpkg -i elasticsearch-1.3.2.deb

 

### Install the Java Service Wrapper for ElasticSearch

curl -L http://github.com/elasticsearch/elasticsearch-servicewrapper/tarball/master | tar -xz

sudo mkdir /usr/local/share/elasticsearch

sudo mkdir /usr/local/share/elasticsearch/bin

sudo mv *servicewrapper*/service /usr/local/share/elasticsearch/bin/

rm -Rf *servicewrapper*

sudo /usr/local/share/elasticsearch/bin/service/elasticsearch install

sudo ln -s `readlink -f /usr/local/share/elasticsearch/bin/service/elasticsearch` /usr/local/bin/rcelasticsearch

### Start ElasticSearch

sudo service elasticsearch start

 

### Make sure service is running

curl http://localhost:9200

 

### Should return something like this:

#{

# "status" : 200,

# "name" : "Storm",

# "version" : {

# "number" : "1.3.1",

# "build_hash" : "2de6dc5268c32fb49b205233c138d93aaf772015",

# "build_timestamp" : "2014-07-28T14:45:15Z",

# "build_snapshot" : false,

# "lucene_version" : "4.9"

# },

# "tagline" : "You Know, for Search"

#}

2. 分別修改每部機器上 /etc/elasticsearch/elasticsearch.yml 設定

cluster.name: elasticsearch

node.name: "elastic_your_nodename"

3. 重新啟動 elasticsearch

sudo service elasticsearch restart

4. 測試 Elasticsearch Cluster 是否有多個 node 出現？本例為2個nodes 

curl -XGET http://elastic_your_nodename:9200/_cluster/health?pretty

{
  "cluster_name" : "elasticsearch",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 2,
  "number_of_data_nodes" : 2,
  "active_primary_shards" : 5,
  "active_shards" : 10,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0
}
