elasticsearch安裝

1、JDK安裝

對于Elasticsearch來說，至少需要JDK1.7上的版本，但我們建議使用Oracle JDK version 1.8.0_73，JDK的安裝這里不再細講，安裝完成之后檢查一下JDK的版本

java -version echo $JAVA_HOME

2、下載最新的Elasticsearch版本

curl -L -O https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.3/elasticsearch-2.3.3.tar.gz

擴展知識

curl參數(shù)說明

-O/--remote-name 把輸出寫到該文件中，保留遠程文件的文件名

3、解壓Elasticsearch

tar -zxvf elasticsearch-2.3.3.tar.gz

3、啟動Elasticsearch

cd elasticsearch-2.3.3/bin

前臺啟動

./elasticsearch

后臺啟動

./elasticsearch -d

[oracle@sigmam1 bin]$ ./elasticsearch

Elasticsearch可以手動修改節(jié)點和集群的名字，也可以在命令行啟動時指定，直接修改：

./elasticsearch --cluster.name my_cluster_name --node.name my_node_name

默認情況下，Elasticsearch對外提供的端口是9200，如果要修改默認端口可以修改config目錄下的

Elasticsearch.yml配置文件
