所有节点安装 ElasticSearch
[root@node160 ~]# mkdir /opt/elk
[root@node160~]# cd /opt/elk
[root@node160~]# wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.1.1/elasticsearch-2.1.1.tar.gz

[root@node160elk]# tar xf elasticsearch-2.1.1.tar.gz
创建启动 elasticsearch 用户
[root@node160bin]# groupadd elk
[root@node160bin]# useradd elk -g elk -p elasticsearch
[root@node162elk]# chown -R elk.elk elasticsearch-2.1.1
[root@node160elk]# passwd elk
更改用户 elk 的密码。
