ELASTICSEARCH2.X Handbook-1th Chapter Getting Started Guide-1.2 Installation

1.2      installation

Elasticsearch requires at least Java 7. We recommend that you use the JDK version 1.8.0_25 of Oracle. When you install Elasticsearch , please check the Java runtime version first.

Java-version Echo $JAVA _home

once we have installed Java, we can download and run Elasticsearch. Binary files can be downloaded from www.elastic.co/downloads and https://github.com/elastic/elasticsearch/releases . For each version, you can choose zip/tar 包 ，或则 deb/rpm 包。 For simplicity, we use tar 包 .

Curl-l-O https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/ 2.1.1/elasticsearch-2.1.1.tar.gz

then unzip the following ( Windows users should unzip the zip package):

Tar-xvfelasticsearch-2.1.1.tar.gz

This will create a bunch of files and folders in your current directory. Then we enter the Bin directory as follows:

CD Elasticsearch-2.1.1/bin

now we are ready to start our node and single cluster(Windows users should run the Elasticsearch.bat file):

./elasticsearch

If all goes well, you should see a bunch of messages like this:

./elasticsearch

we can see that our node is called "Newgoblin"(you will have a different name) that has been started, electing itself as Master in a cluster. There is no need to pay attention to master meaning. The main point is that we have started a node in a cluster.

As mentioned earlier, we can rewrite the cluster or node name. This can be done at the command line when the Elasticsearch is started, as follows:

./elasticsearch--cluster.namemy_cluster_name--node.name My_node_name

also note that the labelHTTPinformation, aboutHTTPAddress (192.168.8.112) and Port (9200). By default,Elasticsearchusing Ports9200provided byREST API. The port is available for distribution.
