作为群集管理员或群集操作员，您可以启用堆栈中的每个服务以自动重新启动。启用服务的自动启动会导致ambari-agent尝试在停止状态下重新启动服务组件，而无需用户手动操作。作为第一步，您应该为核心Hadoop服务中的工作节点，YARN和HDFS中的DataNode和NameNode组件启用自动启动。您还应该为SmartSense服务中的所有组件启用自动启动。启用自动启动后，在Ambari Web仪表板上监控服务的运行状态。自动启动尝试不会显示为后台操作。要管理服务中组件的自动启动状态，请执行以下操作：

### **第一步：** ###

1、在**Ambari Web **> **Cluster Admin中 Service Auto Start**，单击“ **服务自动启动”**。

默认情况下启用自动启动设置，但默认情况下*仅*将Ambari Metrics Collector组件设置为自动启动。

2、要将自动启动设置从“已启用”切换为“已禁用”并返回，请单击“自动启动设置”按钮。

3、要将组件设置为自动重新启动，请单击组件的“ **自动启动”**复选框。

4、要将所有组件设置为自动启动，请单击“ **自动启动”** 复选框。

1.  要在保存之前清除所有挂起状态更改，请单击“ **取消”**。
2.  完成对自动启动设置的更改后，单击“ **保存”**。

**第二步：**

**1、检查自动恢复设置，master节点上输入以下命令，查看设置：**

curl -u admin:<password> -i -H 'X-Requested-By: ambari' -X GET http://localhost:8080/api/v1/clusters/<cluster_name>/components?fields=ServiceComponentInfo/component_name,ServiceComponentInfo/service_name,ServiceComponentInfo/category,ServiceComponentInfo/recovery_enabled

** 注意，您需要使用自己的<password>和<cluster\_name>替换。**

curl -u admin:admin -i -H 'X-Requested-By: ambari' -X GET http://localhost:8080/api/v1/clusters/Siger/components?fields=ServiceComponentInfo/component\_name,ServiceComponentInfo/service\_name,ServiceComponentInfo/category,ServiceComponentInfo/recovery\_enabled

要为所有组件设置启用自动恢复

"recovery\_enabled" : "false",改成"recovery\_enabled" : "true",

**2、master节点上输入以下命令，修改设置：**

curl -u admin:<password> -H "X-Requested-By: ambari" -X PUT 'http://localhost:8080/api/v1/clusters/<cluster_name>/components?ServiceComponentInfo/component_name.in(HBASE_REGIONSERVER)' -d '{"ServiceComponentInfo" : {"recovery_enabled":"true"}}'

curl -u admin:admin -H "X-Requested-By: ambari" -X PUT 'http://localhost:8080/api/v1/clusters/Siger/components?ServiceComponentInfo/component\_name.in(ZKFC,ZOOKEEPER\_CLIENT,ZOOKEEPER\_SERVER,NAMENODE,SECONDARY\_NAMENODE,DATANODE,NFS\_GATEWAY,JOURNALNODE,HDFS\_CLIENT,NIMBUS,STORM\_UI\_SERVER,SUPERVISOR,DRPC\_SERVER,HBASE\_MASTER,HBASE\_REGIONSERVER,PHOENIX\_QUERY\_SERVER,HBASE\_CLIENT,KAFKA\_BROKER,METRICS\_COLLECTOR,METRICS\_GRAFANA,METRICS\_MONITOR)' -d '\{"ServiceComponentInfo" : \{"recovery\_enabled":"true"\}\}'  
**3、浏览器访问**[http://master:8080/api/v1/clusters/atkm/components?fields=ServiceComponentInfo/component\_name,ServiceComponentInfo/service\_name,ServiceComponentInfo/category,ServiceComponentInfo/recovery\_enabled][http_master_8080_api_v1_clusters_atkm_components_fields_ServiceComponentInfo_component_name_ServiceComponentInfo_service_name_ServiceComponentInfo_category_ServiceComponentInfo_recovery_enabled]**，确认是否修改成功**

### **主机关机或者服务非正常停止的情况下才会自动重启** ###
