1.下载

wget https://github.com/prestodb/ambari-presto-service/releases/download/v1.2/ambari-presto-1.2.tar.gz

$mkdir /var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO

$cd /var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO

$tar -xvf /path/to/integration/package/ambari-presto-1.2.tar.gz -C/var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO

$mv /var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO/ambari-presto-1.2/*/var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO

$rm -rf/var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO/ambari-presto-1.2

$chmod -R +x /var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO/*

$ambari-server restart

在线安装会超时，换成离线安装

vi/var/lib/ambari-server/resources/stacks/HDP/2.6/services/PRESTO/package/scripts/download.ini

# yum clean all (清除缓存)

# yum makecache (建立新缓存)

# ambari-server restart

重启Ambari server后，在浏览器UI界面，点击Add Service，根据指示安装Presto。

分布式模式运行，在一个节点上安装Presto coordinator，在其他若干节点（非coordinator节点）上安装Presto worker（不要将worker放置在与coordinator相同的节点上）

可在安装服务presto 服务组件成功后，再配置Connectors参数：

参考内容（目前配了hive和kafka）：

{'hive':['connector.name=hive-hadoop2','hive.metastore.uri=thrift://c2bde55:9083'],'kafka': ['connector.name=kafka','kafka.table-names=ATLAS_ENTITIES,ATLAS_HOOK,ambari_kafka_service_check,testTopic','kafka.nodes=c2bde02:2181,c2bde03:2181,c2bde55:2181']}
