2.3. 集群安装¶
2.3.1. github下载安装包¶
wget https://github.com/prestodb/presto/archive/0.217.tar.gz
2.3.3. coordinator配置¶
coordinator服务器配置信息，主要包含config.properties和node.properties两方面配置信息。
2.3.3.1. config.properties配置¶
coordinator=true
node-scheduler.include-coordinator=false
http-server.http.port=9001
query.max-memory=5GB
query.max-memory-per-node=512MB
query.max-total-memory-per-node=512MB
discovery-server.enabled=true
discovery.uri=http://172.31.134.225:9001
2.3.3.2. node.properties配置¶
node.environment=production
node.id=ffffffff-ffff-ffff-ffff-ffffffffff01
node.data-dir=/opt/presto/data217
2.3.4. worker配置¶
worker服务器配置信息，主要包含config.properties和node.properties两方面配置信息。
2.3.4.1. config.properties配置¶
coordinator=false
node-scheduler.include-coordinator=false
http-server.http.port=9001
query.max-memory=5GB
query.max-memory-per-node=512MB
query.max-total-memory-per-node=512MB
discovery-server.enabled=false
discovery.uri=http://172.31.134.225:9001
2.3.4.2. node.properties配置¶
node.environment配置信息在worker节点和coordinator节点需要保持一致。node.id配置信息必须要唯一。node.data-dir配置目录建议保持一致，方便日志定位。
node.environment=production
node.id=ffffffff-ffff-ffff-ffff-ffffffffff02
node.data-dir=/opt/presto/data217
2.3.5. 修改jvm.properties配置¶
-server
-Xmx1G
-XX:+UseG1GC
-XX:G1HeapRegionSize=32M
-XX:+UseGCOverheadLimit
-XX:+ExplicitGCInvokesConcurrent
-XX:+HeapDumpOnOutOfMemoryError
-XX:+ExitOnOutOfMemoryError
server
以java服务端进程启动
xmx
jvm最大堆内存，该值需要和query.max-memory-per-node之间有关联，不能够query.max-memory-per-node的值大于jvm最大堆大小。
query.max-memory-per-node < xmx*0.8
xmx > query.max-memory-per-node/0.8
xx
UseG1GC使用的是g1的gc收集器进行新生代和老年代gc收集，目前g1是最新性能比较好的gc收集器。
2.3.7. presto服务启动¶
