Presto单机/集群模式安装笔记

一、安装环境

1. JDK版本要求: 1.9.0_92+

二、安装步骤

1. 官网下载最新版本

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

2. 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/log4.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/profile6.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 --catalog hive  

presto> describe hive.dtwave_dev.bas_user_info;
Column | Type | Extra | Comment
——–+———+——-+———
id | integer | |
name | varchar | |
age | integer | |
(3 rows)

Query 20170707_171515_00005_cxg9d, FINISHED, 1 node
Splits: 18 total, 18 done (100.00%)
0:01 [3 rows, 216B] [4 rows/s, 320B/s]

presto> select * from hive.dtwave_dev.bas_user_info limit 10;
id | name | age
—-+——-+—–
1 | zhang | 23
2 | san | 24
3 | li | 35

=============================## 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.propertiescoordinator=truenode-scheduler.include-coordinator=falsetask.max-memory=1GBhttp-server.http.port=8086discovery-server.enabled=truediscovery.uri=http://node172:8086:vim node.propertiesnode.environment=dtwavenode.id=172node.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
