1. 从Elastic官网下载最新版本的Elasticsearch，目前最新版本为V2.3.3。
2. 解压
|
1
|
tar zxvf elasticsearch-2.3.2.tar.gz
|
3. 切换到Elasticsearch的bin目录下，启动服务。
|
1
2
|
./elasticsearch
Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root.
|
启动时会发现Elasticsearch会报如下错误，因为Elasticsearch为安全起见不允许使用root账号启动服务。
4. 创建一个新账号

6. 服务也可以以守护进程方式运行
|
1
|
./elasticsearch -d
|
还可以在启动时同时指定pid
|
1
|
./elasticsearch -d -p pid
|
7. 在浏览器中访问一下，再次确认服务是完好的，但前提是修改/config/elasticsearch.yml，找到 network.host在下面添加一行，然后就可以在浏览器中访问http://10.0.0.5:9200/。
|
1
|
network.host ： 10.0.0.5
|
浏览器显示内容如下：
{
"name" : "Gargouille",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "2.3.2",
"build_hash" : "b9e4a6acad4008027e4038f6abed7f7dba346f94",
"build_timestamp" : "2016-04-21T16:03:47Z",
"build_snapshot" : false,
"lucene_version" : "5.5.0"
},
"tagline" : "You Know, for Search"
} |
至此，Elasticsearch安装启动完毕，更详细的操作还待后文。
