添加hosts信息，保证每台都可以相互ping通

所有安装es的机器都要有该配置

当我们直接访问ES的索引，出现如下信息时，表示license已经过期，需要重新更新
其中涉及ES的账号信息------elastic：是可以 build 这个项目的超级用户，对应默认的密码为：changeme
命令行访问
1 [yun@mini02 ~]$ curl -XGET -u elastic:changeme ‘http://mini01:9200/_xpack/license‘ 2 { 3 "license" : { 4 "status" : "expired", 5 "uid" : "59bc0e32-685b-48a9-bfdb-ddd373f672ab", 6 "type" : "trial", 7 "issue_date" : "2018-06-03T08:56:33.376Z", 8 "issue_date_in_millis" : 1528016193376, 9 "expiry_date" : "2018-07-03T08:56:33.376Z", 10 "expiry_date_in_millis" : 1530608193376, 11 "max_nodes" : 1000, 12 "issued_to" : "zhang-es", 13 "issuer" : "elasticsearch", 14 "start_date_in_millis" : -1 15 } 16 } 17 [yun@mini02 ~]$ curl -XGET -u elastic:changeme ‘http://mini01:9200/_cat/indices‘ 18 {"error":{"root_cause":[{"type":"security_exception","reason":"current license is non-compliant for [security]","license.expired.feature":"security"}],"type":"security_exception","reason":"current license is non-compliant for [security]","license.expired.feature":"security"},"status":403}
浏览器访问
1 http://mini01:9200/_cat/indices
获取License
1 https://register.elastic.co/marvel_register
需要你输入你对应的邮箱等基本信息，随便填写，但是邮箱和国家必须是真实的，将对应新下载的 license 上传到对应集群的某一台服务器上即可，我将我下载的一堆很长名字的 license 修改为简单的名称即：
mv xxxxx-license.json license.json
更新 license
我们更新最新的 license 不需要重启相应的 ElasticSearch 节点，只需要通过一个命令就可以动态的生效
1 [yun@mini02 ~]$ curl -XPUT -u elastic:changeme ‘http://mini01:9200/_xpack/license?acknowledge=true‘ -H "Content-Type: application/json" -d @license.json 2 {"acknowledged":true,"license_status":"valid"} 3 [yun@mini02 ~]$ curl -XGET -u elastic:changeme ‘http://mini01:9200/_xpack/license‘ 4 { 5 "license" : { 6 "status" : "active", 7 "uid" : "aad141e1-c24b-453c-92d1-0fdf5ac63540", 8 "type" : "basic", 9 "issue_date" : "2018-09-07T00:00:00.000Z", 10 "issue_date_in_millis" : 1536278400000, 11 "expiry_date" : "2019-09-07T23:59:59.999Z", 12 "expiry_date_in_millis" : 1567900799999, 13 "max_nodes" : 100, 14 "issued_to" : "zhang lia (myself)", 15 "issuer" : "Web Form", 16 "start_date_in_millis" : 1536278400000 17 } 18 }
之后就可以正常访问了
