在Kibana上面配置权限，验证对Elasticsearch权限控制,
主要步骤如下：
1.创建角色
2.创建用户，并且赋予用户角色
3.用户登陆，验证没有权限
4.赋予角色权限
5.用户登陆，验证拥有权限

具体测试步骤：

1.创建用户yuewn

Kibana -> Managemet -> Users -> Create User
yuwen/zdh1234
先不给用户配置角色

2.开启X-Pack插件的Elasticsearch查询集群健康

不携带用户名和密码会报错

curl -XGET 'localhost:9200/_cat/health?v&pretty'

携带用户名和密码查询OK

curl -u elastic:ce0YpqhLZykDWGdnjvlP -XGET 'localhost:9200/_cat/health?v&pretty'

3.使用超级用户elastic列出所有索引,成功

curl -u elastic:ce0YpqhLZykDWGdnjvlP -XGET 'localhost:9200/_cat/indices?v&pretty'

使用普通用户yuwen列出所有索引，会报错

curl -u yuwen:zdh1234 -XGET 'localhost:9200/_cat/indices?v&pretty'

报错如下：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "security_exception",
        "reason" : "action [cluster:monitor/state] is unauthorized for user [yuwen]"
      }
    ],
    "type" : "security_exception",
    "reason" : "action [cluster:monitor/state] is unauthorized for user [yuwen]"
  },
  "status" : 403
}

4.赋予普通用户yuwen超级角色的权限

普通用户yuwen列出所有索引，成功

curl -u yuwen:zdh1234 -XGET 'localhost:9200/_cat/indices?v&pretty'

成功结果如下：

health status index                           uuid                   pri rep docs.count docs.deleted store.size pri.store.size
......
yellow open   megacorp                        uTEXgdwGTDGmwSKJVNtvrA   5   1          3            0     17.5kb         17.5kb
......

5.elasticsearch打开debug日志

/home/elasticsearch/elasticsearch-6.2.2/config/log4j2.properties
/x-pack/log4j2.properties

elasticsearch_log4j2.properties

# log action execution errors for easier debugging
logger.action.name = org.elasticsearch.action
logger.action.level = debug
logger.action.ref = rolling
logger.action.additivity = false


rootLogger.level = info
rootLogger.appenderRef.console.ref = console
rootLogger.appenderRef.rolling.ref = rolling

x-pack_log4j2.properties

logger.xpack_security_audit_logfile.name = org.elasticsearch.xpack
logger.xpack_security_audit_logfile.level = debug
logger.xpack_security_audit_logfile.appenderRef.audit_rolling.ref = audit_rolling
logger.xpack_security_audit_logfile.additivity = false

appender.audit_rolling.layout.pattern = [%d{ISO8601}][%-5p][%-25c{1.}] %marker%.-10000m%n

6.进一步测试，设置如下的用户进行测试：

1.用户yuwen有超级用户的权限
2.用户yuwen1不存在
3.用户zhangqian存在，但没有任何权限

curl -u zhangqian:zdh1234 -XGET 'localhost:9200/_cat/indices?v&pretty'
curl -u yuwen:zdh1234 -XGET 'localhost:9200/_cat/indices?v&pretty'
