elasticsearch创建用户、角色

我们要创建一个叫xjw的用户，这个用户要有较高的es权限和kibana权限，同时实现多用户下的数据隔离

---

先创建角色
indices下的names属性里配置的是我们能操作的索引、模版等等数据的前缀“xjw-”，如果不带这个前缀会报错403

PUT _security/role/ly_role
{"cluster": ["all"],"indices": [{"names": ["xjw-*"],"privileges": ["all"],"allow_restricted_indices": false},{"names": [".kibana*",".kibana_task_manager*",".kibana-observability*",".kibana_reporting*",".fleet*"],"privileges": ["all"],"allow_restricted_indices": true   // 必须 true，这些是受限索引}],"applications": [{"application": "kibana-.kibana","privileges": ["all"],"resources": ["*"]}],"metadata": {"description": "xjw 用户：业务索引隔离 + Kibana 全权限"}
}

---

创建用户

POST _security/user/xjw
{"password": "passwd","roles": ["ops_power"]
}

然后就可以用用户名xjw，密码passwd登录es和kibana了
