Presto安裝和部署

（1）官網下載安裝包

presto-server-0.196.tar.gz        
presto-cli-0.196-executable.jar

（2）解壓
（3）創建Presto的日誌目錄
mkdir -p /home/hadoop/presto_data
（4）在Presto安裝目錄下創建etc目錄

mkdir -p /home/hadoop/app/presto-server-0.196/etc

（5）在Presto的etc目錄下創建四個配置文件：
1）node.properties

node.environment=production
node.id=ffffffff-ffff-ffff-ffff-ffffffffffff-001
node.data-dir=/home/hadoop/presto_data

2）jvm.properties

-server
-Xmx4G
-XX:+UseG1GC
-XX:G1HeapRegionSize=32M
-XX:+UseGCOverheadLimit

3）config.properties

coordinator=true
node-scheduler.include-coordinator=true
http-server.http.port=8080
query.max-memory=2GB
query.max-memory-per-node=1GB
query.max-total-memory-per-node=2GB
discovery-server.enabled=true
discovery.uri=http://hadoop000:8080

4）log.properties

com.facebook.presto=INFO

（6）在Presto的etc目錄下創建catalog目錄

mkdir -p /home/hadoop/app/presto-server-0.196/etc/catalog

（7）在Presto的/etc/catalog目錄下創建jmx.properties，加入以下內容：

connector.name=jmx

（8）啓動Presto
前端運行：

/home/hadoop/app/presto-server-0.196/bin/launcher run

後端運行：

/home/hadoop/app/presto-server-0.196/bin/launcher start

報錯：Configuration property 'query.max-total-memory-per-node' was not used

解決方案：註釋掉config.properties中的

query.max-total-memory-per-node=2GB

（9）查看Presto WebUI
