presto-mysql/elasticsearch6.0.0安装部署测试，异种数据源关联查询入门实践

本文简单记录一次实践使用过程，涉及presto-mysql,presto-elasticsearch，文中参数未做注释，请参考官方文档，希望能帮到大家

1 下载安装 presto-0.228

<1>下载

服务端

https://repo1.maven.org/maven2/com/facebook/presto/presto-server/0.228/presto-server-0.228.tar.gz

客户端

https://repo1.maven.org/maven2/com/facebook/presto/presto-cli/0.228/presto-cli-0.228-executable.jar

相关jar

https://repo1.maven.org/maven2/com/facebook/presto/presto-base-jdbc/0.228/presto-base-jdbc-0.228.jar

https://repo1.maven.org/maven2/com/facebook/presto/presto-spi/0.228/presto-spi-0.228.jar

<2>安装：

1> 解压

tar -zxvf presto-server-0.228.tar.gz

2>创建配置目录 etc  etc/catalog

cd presto-server-0.228/

mk dir etc

mkdir etc

mkdir data

cd etc

mkdir catalog

3>创建config.properties 集群配置

在新建的etc目录下

vim config.properties

coordinator=true

node-scheduler.include-coordinator=true

http-server.http.port=9080

query.max-memory=8GB

query.max-memory-per-node=1GB

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

discovery-server.enabled=true

discovery.uri=http://xinyi:9080

4>创建jvm.config 运行环境配置

在新建的etc目录下

vim jvm.config

-server

-Xmx16G

-XX:+UseG1GC

-XX:G1HeapRegionSize=32M

-XX:+UseGCOverheadLimit

-XX:+ExplicitGCInvokesConcurrent

-XX:+HeapDumpOnOutOfMemoryError

-XX:+ExitOnOutOfMemoryError

5>创建log.properties 日志配置

在新建的etc目录下

vim log.properties

com.facebook.presto=INFO

6>创建node.properties ，节点配置

在新建的etc目录下

vim log.properties

node.environment=production

node.id=ffffffff-ffff-ffff-ffff-fffffffffff1

node.data-dir=/opt/presto-server-0.228/data

7>启动

cd /安装目录/bin

./launcher start 后台启动

./launcher stop停止

./launcher run 前台启动，输出日志

./launcher restart 重启

8>/安装目录/var/log以下位置找到日志文件

launcher.log

server.log

http-request.log

<3> 安装客户端

重命名presto-cli-0.228-executable.jar位presto

mv presto-cli-0.228-executable.jar presto

使用命令：

./presto --server locahost:9080 --catalog mysql--schema test

2 presto-mysql

<1>在 /etc/catalog/目录下创建mysql.properties

connector.name=mysql

connection-url=jdbc:mysql://localhost:3306

connection-user=root

connection-password=root

<2>重启presto-server

/launcher restart

<3>测试

在客户端安装目录执行

./presto --server locahost:9080 --catalog mysql--schema test

presto:es> select * from mysql.test.test;

3 presto-elasticsearch

elasticsearch版本最好与plugin目录下elasticsearch版本一致

<1>在 /安装目录/etc/catalog/目录下创建elasticsearch.properties

connector.name=elasticsearch

#elasticsearch.default-schema=default

elasticsearch.table-description-directory=etc/elasticsearch/

elasticsearch.scroll-size=1000

elasticsearch.scroll-timeout=2s

elasticsearch.request-timeout=2s

elasticsearch.max-request-retries=5

elasticsearch.max-request-retry-time=10s

<2>创建elasticsearch目录

cd /安装目录/etc/

mkdir elasticsearch

cd elasticsearch

<3>定义表的描述文件（自定义表名.json）

cd elasticsearch

vim test.json

{"tableName": "es_test",

"schemaName": "es",

"host": "es-ip地址",

"port": 9300,

"clusterName": "my-application",

"index": "test",

"indexExactMatch": false,

"type": "test",

"columns": [

{

"name": "name",

"type": "varchar",

"jsonPath":"name",

"jsonType":"varchar"

},

{

"name": "age",

"type": "integer",

"jsonPath":"age",

"jsonType":"integer"

}

]

}

<4>重启presto-server

/launcher restart

<5>测试

./presto --server locahost:9080 --catalog elasticsearch --schema es

presto:es> select * from elasticsearch.es.es_test;

name | age

------+-----

HL   |  12

HLl  |  18

(2 rows)

4 多数据源查询

./presto --server locahost:9080 --catalog elasticsearch --schema es

presto:es> select * from mysql.test.user t left join elasticsearch.es.es_test t1 on t.age=t1.age;
