安装
下载(https://repo1.maven.org/maven2/com/facebook/presto/presto-server/0.152.3/presto-server-0.152.3.tar.gz "presto-server-0.152.3.tar.gz")并解压安装，设置环境变量"PRESTO_HOME"
下载(https://repo1.maven.org/maven2/com/facebook/presto/presto-cli/0.152.3/presto-cli-0.152.3-executable.jar "presto-cli-0.152.3-executable.jar")，并将它重命名为"presto"，设置为可执行，放在"$PRESTO_HOME/bin"下，并把"$PRESTO_HOME/bin"加到环境变量"PATH"

快速指南
# 启动
$PRESTO_HOME/bin/launcher run
# 后台进程启动
$PRESTO_HOME/bin/launcher start
# 停止
$PRESTO_HOME/bin/launcher stop
# 访问cassandra数据库
$PRESTO_HOME/bin/presto --server localhost:8090 --catalog cassandra --schema dmp
# 输出csv
$PRESTO_HOME/bin/presto --server localhost:8090 --catalog cassandra --schema dmp --execute "select * from user_tags limit 20" --output-format CSV > user_tags.csv
无法通过rpc访问cassandra
需要在cassandra.yaml中打开相关设置
start_rpc: true
连接远程hive
远程hive(192.168.11.61)启动metastore服务
hive --service metastore
在presto的catalog目录放连接文件hive_online.properties
connector.name=hive-hadoop2
hive.metastore.uri=thrift://192.168.11.61:9083
