# 修改参数配置 - UpdateYmls #### 功能介绍 Elasticsearch集群的核心配置信息都集中在"elasticsearch.yml"和"kibana.yml"文件中，OpenSearch集群的核心配置信息都集中在"opensearch.yml"和"opensearch_dashboards.yml"文件中。当需要根据业务需求调整集群的运行行为时，比如优化查询速度、修改跨域访问配置、调整内部缓存大小或管理后台任务队列等，则可以通过修改参数配置实现。 在使用该接口之前，建议先调用[获取参数配置列表](https://support.huaweicloud.com/api-css/ListYmls.html)，确认集群的参数配置情况，便于根据需求修改参数配置。 #### 接口约束 当参数类型UpdateYmlsReqEditModify为elasticsearch.yml时，自定义参数必须配置为Elasticsearch或OpenSearch支持的参数，否则集群重启会失败。 当参数类型UpdateYmlsReqEditModify为kibana.yml时，自定义参数必须配置为Kibana或Dashboards支持的参数，否则Kibana或Dashboards进程重启会失败。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-css/css_03_0077.html)。 #### 授权信息 账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。 - 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-css/css_03_0096.html)。 - 如果使用身份策略授权，需具备如下身份策略权限。 | 授权项 | 访问级别 | 资源类型（\*为必须） | 条件键 | 别名 | 依赖的授权项 | |:---|:---|:---|:---|:---|:---| | css:configurations:modify | Write | cluster \* | - g:EnterpriseProjectId - g:ResourceTag/\ | - | - | #### URI POST /v1.0/{project_id}/clusters/{cluster_id}/ymls/update 表1路径参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | project_id | 是 | String | **参数解释**： 项目ID。获取方法请参见[获取项目ID和名称](https://support.huaweicloud.com/api-css/css_03_0071.html)。 **约束限制**： 不涉及 **取值范围**： 账户的项目ID，长度为32个字符，由小写字母和数字组成。 **默认取值**： 不涉及 | | cluster_id | 是 | String | **参数解释**： 指定修改参数配置的集群ID。获取方法请参见[获取集群ID](https://support.huaweicloud.com/api-css/css_03_0101.html)。 **约束限制**： 不涉及 **取值范围**： UUID格式，36个字符。 **默认取值**： 不涉及 | #### 请求参数 表2请求Body参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | edit | 是 | [UpdateYmlsReqEdit] object | **参数解释**： 配置文件信息。 **约束限制**： 不涉及 | | inst_type | 否 | String | **参数解释**： 节点类型。 **约束限制**： KooSearch集群涉及不同类型的节点，其他类型集群不涉及。 **取值范围**： - kos: KooSearch的搜索中控节点 - kos-doc: KooSearch的文档解析节点 **默认取值**： 不涉及 | 表3UpdateYmlsReqEdit | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | modify | 否 | [UpdateYmlsReqEditModify] object | **参数解释**： 修改参数配置的操作。 **约束限制**： - modify、delete、reset至少一个生效，且每次每个操作仅可使用一次。 - 不能对同种参数同时进行多种操作。 | | delete | 否 | [UpdateYmlsReqEditModify] object | **参数解释**： 删除自定义参数配置的操作。 **约束限制**： - 与传入的参数值无关。 - modify、delete、reset至少一个生效，且每个操作仅可使用一次。 - 不能对同种参数同时进行多种操作。 | | reset | 否 | [UpdateYmlsReqEditModify] object | **参数解释**： 重置参数配置的操作。 **约束限制**： - 与传入的参数值无关。 - 不支持重置自定义参数。 - modify、delete、reset至少一个生效，且每个操作仅可使用一次。 - 不能对同种参数同时进行多种操作。 | 表4UpdateYmlsReqEditModify | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | elasticsearch.yml | 否 | Object | **参数解释**： 参数配置列表，值为需要修改的json数据，key为Elasticsearch/OpenSearch支持的配置参数名，value为对应的配置参数值。修改Elasticsearch集群（elasticsearch.yml）或OpenSearch集群（opensearch.yml）的参数时，这里均填写elasticsearch.yml。 **约束限制**： 自定义参数必须配置为Elasticsearch或OpenSearch支持的参数，否则集群重启会失败，建议谨慎操作，以免影响业务。 | | kibana.yml | 否 | Object | **参数解释**： 参数配置列表，值为需要修改的json数据，key为Kibana或Dashboards支持的配置参数名，value为对应的配置参数值。修改Elasticsearch集群（kibana.yml）或OpenSearch集群（opensearch_dashboards.yml）的参数时，这里均填写kibana.yml。 **约束限制**： 自定义参数必须配置Kibana或Dashboards支持的参数，否则Kibana或Dashboards进程重启会失败，建议谨慎操作。 | | system.config | 否 | Object | **参数解释**： 参数配置列表，值为需要修改的json数据，即集群修改system.config时，会在Elasticsearch或OpenSearch集群config目录下生成descriptor.xml文件。 **约束限制**： json数据中key值为descriptor.xml，value值允许输入最大长度不能超过100KB（102400字节/字符，包含换行符）。 | #### 响应参数 **状态码：200** 表5响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | acknowledged | Boolean | **参数解释**： 修改参数配置是否成功。 **取值范围**： - true: 修改成功。 - false: 修改失败。 | | externalMessage | String | **参数解释**： 错误信息描述。 **取值范围**： 当acknowledged为true时，该字段返回null。 | | httpErrorResponse | String | **参数解释**： HTTP错误信息，默认为null。 **取值范围**： 不涉及 | #### 请求示例 - 修改参数配置。 ``` POST https://{Endpoint}/v1.0/{project_id}/clusters/4f3deec3-efa8-4598-bf91-560aad1377a3/ymls/update { "edit" : { "modify" : { "elasticsearch.yml" : { "thread_pool.force_merge.size" : 1 } } } } ``` - 删除自定义参数配置。 ``` POST https://{Endpoint}/v1.0/{project_id}/clusters/4f3deec3-efa8-4598-bf91-560aad1377a3/ymls/update { "edit" : { "delete" : { "elasticsearch.yml" : { "thread_pool.force_merge.size" : 1 } } } } ``` - 重置参数配置的操作 ``` POST https://{Endpoint}/v1.0/{project_id}/clusters/4f3deec3-efa8-4598-bf91-560aad1377a3/ymls/update { "edit" : { "reset" : { "elasticsearch.yml" : { "http.cors.allow-credentials" : "false" } } } } ``` #### 响应示例 **状态码：200** 请求成功。 ``` { "acknowledged" : true, "externalMessage" : null, "httpErrorResponse" : null } ``` #### SDK代码示例 SDK代码示例如下。 - [Java] - 修改参数配置。 ``` package com.huaweicloud.sdk.test; import com.huaweicloud.sdk.core.auth.ICredential; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ConnectionException; import com.huaweicloud.sdk.core.exception.RequestTimeoutException; import com.huaweicloud.sdk.core.exception.ServiceResponseException; import com.huaweicloud.sdk.css.v1.region.CssRegion; import com.huaweicloud.sdk.css.v1.*; import com.huaweicloud.sdk.css.v1.model.*; public class UpdateYmlsSolution { public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great security risks.
