Presto单机/集群模式安装笔记

一、安装环境

JDK版本要求: 1.9.0_92+

二、安装步骤

官网下载最新版本

https://prestodb.io/docs/current/installation/deployment.html
配置，参考网址

http://prestodb-china.com/docs/current/installation/deployment.html

etc/node.properties暂时配置如下:
node.data-dir=/opt/dtwave/presto/data (新建data目录)

注意删除etc/config.properties中的task.max-memory=1GB。否则启动报如下错误:

启动服务: bin/launcher start

ERROR com.facebook.presto.server.PrestoServer Unable to create injector, see the following errors:

1) Error: Invalid configuration property node.environment: is malformed (for class io.airlift.node.NodeConfig.environment)

2) Error: Defunct property 'task.max-memory' (class [class com.facebook.presto.execution.TaskManagerConfig]) cannot be configured.

3.查询日志目录

/opt/dtwave/presto/data/var/log

4.浏览器查看

http://ip:8086/

5.下载客户端，下载到／opt/dtwave/presto/bin目录下

https://prestodb.io/docs/current/installation/cli.html

重命名为 presto-cli

$ mv presto-cli-0.180-executable.jar presto-cli

$ chmod +x presto-cli

添加环境变量 /etc/profile

export PRESTO_HOME=/opt/dtwave/presto

export PATH=$PATH:$PRESTO_HOME/bin

source /etc/profile

6.配置Hive连接器，etc/catalog目录新建 hive.properties, 内容如下:

connector.name=hive-hadoop2

hive.metastore.uri=thrift://master106:9083

hive.config.resources=/opt/dtwave/hadoop/etc/hadoop/core-site.xml,/opt/dtwave/hadoop/etc/hadoop/hdfs-site.xml

7.连接Hive,

presto-cli –server outer_ip:8086 –catalog hive –schema default

presto-cli –server inner_ip:8086 –catalog hive –schema default

或者（不指定数据库）

presto-cli –server ip:8086 –cata 大专栏 Presto单机/集群模式安装笔记log hive

presto> describe hive.dtwave_dev.bas_user_info;

 Column |  Type   | Extra | Comment

=============================

三、集群模式安装:

从第一台安装好的persto机器上scp 文件夹过去

scp -r presto-server-0.180 hadoop@node47:/opt/dtwave/

scp -r presto-server-0.180 hadoop@1node.50:/opt/dtwave/

scp -r presto-server-0.180 hadoop@node172:/opt/dtwave/

scp -r jdk1.8.0_131 hadoop@node47:/opt/dtwave/

scp -r jdk1.8.0_131 hadoop@node50:/opt/dtwave/

scp -r jdk1.8.0_131 hadoop@node172:/opt/dtwave/

创建软链接：

ln -s presto-server-0.180 presto

删除目录/presto/data下所有旧文件。

配置环境变量：

export PRESTO_HOME=/opt/dtwave/presto

export PATH=$PATH:$PRESTO_HOME/bin

source /etc/profile

删除旧版本jdk软连接

rm -rf jdk

创建软链接升级JDK：

ln -s jdk1.8.0_131 jdk

3.1 集群模式修改配置部分

把Node172作为coordinator Node45和Node47作为Node。修改配置后重新启动。

3.1.1 coordinator 节点配置。

Node172配置

:vim config.properties

coordinator=true
node-scheduler.include-coordinator=false
task.max-memory=1GB
http-server.http.port=8086
discovery-server.enabled=true
discovery.uri=http://node172:8086

:vim node.properties

node.environment=dtwave
node.id=172
node.data-dir=/opt/dtwave/presto/data

3.1.2 node节点配置：【注意coordinator=false】

Node50

coordinator=false

http-server.http.port=8086

discovery-server.enabled=true

discovery.uri=http://node172:8086

node.environment=dtwave

node.id=50

node.data-dir=/opt/dtwave/presto/data

Node47

coordinator=false

http-server.http.port=8086

discovery-server.enabled=true

discovery.uri=http://node172:8086

node.environment=dtwave

node.id=47

node.data-dir=/opt/dtwave/presto/data

3.2 Cli远程连接测试：（指定Server为172）

presto-cli --server node172:8086 --catalog hive --schema default
