elasticsearch安装-创新互联

1、JDK安装

对于Elasticsearch来说，至少需要JDK1.7上的版本，但我们建议使用Oracle JDK version 1.8.0_73，JDK的安装这里不再细讲，安装完成之后检查一下JDK的版本

java -version echo $JAVA_HOME

2、下载最新的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

扩展知识

curl参数说明

-O/--remote-name 把输出写到该文件中，保留远程文件的文件名

3、解压Elasticsearch

tar -zxvf elasticsearch-2.3.3.tar.gz

3、启动Elasticsearch

cd elasticsearch-2.3.3/bin

前台启动

./elasticsearch

后台启动

./elasticsearch -d

[oracle@sigmam1 bin]$ ./elasticsearch

Elasticsearch可以手动修改节点和集群的名字，也可以在命令行启动时指定，直接修改：

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

默认情况下，Elasticsearch对外提供的端口是9200，如果要修改默认端口可以修改config目录下的

Elasticsearch.yml配置文件
