ambari之api安装组件
Ambari Blueprints 是用来自动化安装hdp组件的配置文件，它告诉ambari：要安装什么service/component，安装在哪里。
导出蓝图
curl -H "X-Requested-By:ambari" --user admin:admin -X GET http://localhost:8080/api/v1/clusters/BFD_test?format=blueprint > export_blueprint.json
BFD_test导出的集群
下面就是这个配置文件的简化版，介绍它的框架结构
{
"configurations" : [
### 定义hdp里面各个组件的配置，也可以不写，使用默认配置。
],
"host_groups" : [
{
"components" : [
{ "name": "NODEMANAGER" },
{ "name": "DATANODE" },
{ "name" : "METRICS_MONITOR" }
],
"configurations" : [ ],
"name" : "host_group_1",
"cardinality" : "1"
},
{
### 定义哪个host group 安装什么component。
} ...
],
"settings" : [
### 其它设置，比如component自启动。可以不写。
],
"Blueprints" : {
"stack_name" : "HDP",
"stack_version" : "2.6"
### Blueprint and stack information
}
}
一、 向ambari注册blueprint
三集群，自己定义的，也可以拿自己导出的蓝图
创建蓝图cluster.json
{
"configurations" : [
],
"host_groups" : [
{
"components" : [
{
"name" : "SPARK_CLIENT"
},
{
"name" : "YARN_CLIENT"
},
{
"name" : "HDFS_CLIENT"
},
{
"name" : "HIVE_SERVER"
},
{
"name" : "HISTORYSERVER"
},
{
"name" : "METRICS_MONITOR"
},
{
"name" : "HIVE_METASTORE"
},
{
"name" : "TEZ_CLIENT"
},
{
"name" : "ZOOKEEPER_CLIENT"
},
{
"name" : "PIG"
},
{
"name" : "WEBHCAT_SERVER"
},
{
"name" : "SECONDARY_NAMENODE"
},
{
"name" : "HST_AGENT"
},
{
"name" : "MAPREDUCE2_CLIENT"
},
{
"name" : "SLIDER"
},
{
"name" : "ZOOKEEPER_SERVER"
},
{
"name" : "APP_TIMELINE_SERVER"
},
{
"name" : "HIVE_CLIENT"
},
{
"name" : "MYSQL_SERVER"
},
{
"name" : "RESOURCEMANAGER"
}
],
"configurations" : [ ],
"name" : "host_group_2",
"cardinality" : "1"
},
{
"components" : [
{
"name" : "YARN_CLIENT"
},
{
"name" : "HDFS_CLIENT"
},
{
"name" : "HST_SERVER"
},
{
"name" : "METRICS_MONITOR"
},
{
"name" : "NAMENODE"
},
{
"name" : "TEZ_CLIENT"
},
{
"name" : "ACTIVITY_ANALYZER"
},
{
"name" : "ACTIVITY_EXPLORER"
},
{
"name" : "HST_AGENT"
},
{
"name" : "MAPREDUCE2_CLIENT"
},
{
"name" : "ZOOKEEPER_SERVER"
},
{
"name" : "AMBARI_SERVER"
},
{
"name" : "SPARK_JOBHISTORYSERVER"
},
{
"name" : "METRICS_GRAFANA"
}
],
"configurations" : [ ],
"name" : "host_group_1",
"cardinality" : "1"
},
{
"components" : [
{
"name" : "NODEMANAGER"
},
{
"name" : "SPARK_CLIENT"
},
{
"name" : "YARN_CLIENT"
},
{
"name" : "HDFS_CLIENT"
},
{
"name" : "METRICS_MONITOR"
},
{
"name" : "TEZ_CLIENT"
},
{
"name" : "ZOOKEEPER_CLIENT"
},
{
"name" : "HCAT"
},
{
"name" : "PIG"
},
{
"name" : "HST_AGENT"
},
{
"name" : "MAPREDUCE2_CLIENT"
},
{
"name" : "SLIDER"
},
{
"name" : "ZOOKEEPER_SERVER"
},
{
"name" : "DATANODE"
},
{
"name" : "HIVE_CLIENT"
},
{
"name" : "METRICS_COLLECTOR"
}
],
"configurations" : [ ],
"name" : "host_group_3",
"cardinality" : "1"
}
],
"settings" : [
{
"recovery_settings" : [
{
"recovery_enabled" : "true"
}
]
},
{
"service_settings" : [
{
"name" : "HIVE",
"credential_store_enabled" : "true"
},
{
"recovery_enabled" : "true",
"name" : "AMBARI_METRICS"
}
]
},
{
"component_settings" : [
{
"recovery_enabled" : "true",
"name" : "METRICS_COLLECTOR"
}
]
}
],
"Blueprints" : {
"stack_name" : "HDP",
"stack_version" : "2.6"
}
}
curl -H "X-Requested-By: ambari" -X POST \
-u admin:admin \
http://localhost:8080/api/v1/blueprints/roycluster?validate_topology=false \
-d @cluster.json
二、创建集群模板host_map.json，并安装
把 host 和 blueprint 中的 host_group 对应起来,让ambari安装hdp组件
{
"blueprint" : "roycluster", ###蓝图名
"default_password" : "admin",
"configurations" : [
],
"host_groups" :[
{
"name" : "host_group_1", ###把 host 和 blueprint file 中的 host_group 对应起来
"hosts" : [
{
"fqdn" : "node1"
}
]
},
{
"name" : "host_group_2",
"hosts" : [
{
"fqdn" : "node2"
}
]
},
{
"name" : "host_group_3",
"hosts" : [
{
"fqdn" : "node3"
}
]
}
]
}
运行是去掉文件中文
curl -H "X-Requested-By: ambari" -X POST -u admin:admin http://localhost:8080/api/v1/clusters/roycluster -d@host_map.json
基础操作
查看集群
curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://localhost:8080/api/v1/clusters
查看组件
curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://localhost:8080/api/v1/clusters/roycluster/services
删除组件
curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://localhost:8080/api/v1/clusters/roycluster/services/ZOOKEEPER
删除集群
curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://localhost:8080/api/v1/clusters/roycluster
roycluster删除的ambari集群名
我个人感觉ambari blueprint 首先通过host_map在ambari创建集群模板,到blueprint里注册，并配置配置文件
