1. 从下载最新版本的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
| 1 2 3 4 5 6 7 8 | [root@Server01 bin] # useradd elasticsearchuser [root@Server01 bin] # passwd elasticsearchuser Changing password for user elasticsearchuser. New password: BAD PASSWORD: is too simple Retype new password: passwd : all authentication tokens updated successfully. [root@Server01 bin] # usermod -g root elasticsearchuser |
5. 重新启动服务。

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。
| 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。
