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
tar zxvf elasticsearch-2.3.2.tar.gz
3. 切换到Elasticsearch的bin目录下,启动服务。
./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
[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
./elasticsearch -d
还可以在启动时同时指定pid
./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/。
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。
