这里以file,native为例

 

 

Elasticsearch with Shield

一.停止所有elasticsearch节点

说明:shield安装，卸载，升级都需要重启elasticsearch节点

 

二.安装shield插件(所有elasticsearch节点)

说明:shield版本必须和elasticsearch保持一致

在线安装

/opt/elasticsearch-2.3.2/bin/plugin install license

/opt/elasticsearch-2.3.2/bin/plugin install shield

或离线安装

wget 

wget 

/opt/elasticsearch-2.3.2/bin/plugin install file:///root/license-2.3.2.zip 

/opt/elasticsearch-2.3.2/bin/plugin install file:///root/shield-2.3.2.zip

 

[root@ela-master1 ~]# /opt/elasticsearch-2.3.2/bin/plugin install file:///root/license-2.3.2.zip

[root@ela-master1 ~]# /opt/elasticsearch-2.3.2/bin/plugin install file:///root/shield-2.3.2.zip

Installed shield into /opt/elasticsearch-2.3.2/plugins/shield

 

注意:一旦shield安装成功，在elasticsearch重启后，对elasticsearch的任何操作都需要授权(用户名和密码)，除非启用匿名用户

 

三.配置realm

A.配置file-realm(所有节点)

1.增加file-realm配置

cat >>/opt/elasticsearch-2.3.2/config/elasticsearch.yml <<HERE

shield.authc.realms.file1.type: file

shield.authc.realms.file1.order: 0

HERE

2.启动(或重启)elasticsearch

3.创建file based用户

/opt/elasticsearch-2.3.2/bin/shield/esusers useradd es_admin -p P@ssw0rd -r admin

/opt/elasticsearch-2.3.2/bin/shield/esusers useradd kibana -p P@ssw0rd -r kibana4_server

[root@ela-client ~]# /opt/elasticsearch-2.3.2/bin/shield/esusers list

es_admin       : admin

kibana         : kibana4_server

说明:这里创建了两个用户es_admin(用户名 es_admin, 密码P@ssw0rd, 角色admin)和kibana,用户角色定义可以参看shield配置文 件/opt/elasticsearch-2.3.2/config/shield/roles.yml

4.file based用户同步到集群其它节点

注意:对于用户和角色的所有操作默认都存放在如下位置，因此集群中的所有节点都需要上面同样的操作，当然，也可以直接copy如下文件到其它节点的对应目录

/opt/elasticsearch-2.3.2/config/shield/users

/opt/elasticsearch-2.3.2/config/shield/users_roles

5.测试用户认证

[root@ela-client ~]# curl -u es_admin:P@ssw0rd 'http://localhost:9200/_cat/health?v'

epoch      timestamp cluster               status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent 

1462705707 19:08:27  elasticsearch_cluster green           6         2     52  26    0    0       0             0                  -                100.0% 

[root@ela-client ~]# curl -u es_admin:P@ssw0rd 'http://localhost:9200/_cat/indices?v'

health status index               pri rep docs.count docs.deleted store.size pri.store.size 

green  open   shakespeare           5   1     111396            0     36.5mb         18.2mb

green  open   bank                  5   1       1000            0    890.5kb       447.9kb 

green  open   .kibana               1   1          4            0     44.5kb        22.2kb 

green  open   logstash-2015.05.18   5   1       4631            0     64.9mb         32.7mb 

green  open   logstash-2015.05.19   5   1       4624            0     66.7mb           32mb 

 

B.配置native-realm(所有节点)

默认情况下, native-realm已经被配置到了realm链里, 可以直接通过

REST API来添加删除用户，修改用户密码及管理角色, 这也是

官方推荐的认证方式

1.增加native-realm配置

cat >>/opt/elasticsearch-2.3.2/config/elasticsearch.yml <<HERE

shield.authc.realms.native1.type: native

shield.authc.realms.native1.order: 0

HERE

2.启动(或重启)elasticsearch

3.创建native用户

curl -u es_admin:P@ssw0rd -XPOST 'http://localhost:9200/_shield/user/fooadmin' -d '

{

  "password" : "foo.123", 

  "roles" : [ "admin", "other_role1" ], 

  "full_name" : "Jlive Liu", 

  "email" : "iliujun_live@163.com", 

  "metadata" : { 

    "intelligence" : 7

  }

}

'

说明:

1.新增native用户也需要认证，但启用了shield之后默认是没有native用户的，所以就需要借助file based用户来授权

2.native用户是存放在elasticsearch集群中，集群中的所有节点会自动同步

[root@ela-client ~]# curl -u es_admin:P@ssw0rd -XPOST 'http://localhost:9200/_shield/user/fooadmin' -d '

{

  "password" : "foo.123", 

  "roles" : [ "admin", "other_role1" ], 

  "full_name" : "Jlive Liu", 

  "email" : "iliujun_live@163.com", 

  "metadata" : { 

    "intelligence" : 7

  }

}

'

 

{"user":{"created":true}}

[root@ela-data1 ~]# curl -u es_admin:P@ssw0rd 'http://localhost:9200/_shield/user'

{"fooadmin":{"username":"fooadmin","roles":["admin","other_role1"],"full_name":"Jlive Liu","email":"iliujun_live@163.com","metadata":{"intelligence":7}}}

4.测试用户认证

[root@ela-master2 ~]# curl -u fooadmin:foo.123 'http://localhost:9200/_cat/health?v'
