This chapter will explain how to install Presto on your machine. Let’s go through the basic requirements of Presto,
Now, let’s continue the following steps to install Presto on your machine.
Hopefully, you have already installed Java version 8 on your machine right now, so you just verify it using the following command.
$ java -version
If Java is successfully installed on your machine, you could see the version of installed Java. If Java is not installed, follow the subsequent steps to install Java 8 on your machine.
Download JDK. Download the latest version of JDK by visiting the following link.
The latest version is JDK 8u 92 and the file is “jdk-8u92-linux-x64.tar.gz”. Please download the file on your machine.
After that, extract the files and move to the specific directory.
Then set Java alternatives. Finally Java will be installed on your machine.
Download the latest version of Presto by visiting the following link,
Now the latest version of “presto-server-0.149.tar.gz” will be downloaded on your machine.
Extract the tar file using the following command −
$ tar -zxf presto-server-0.149.tar.gz $ cd presto-server-0.149
Create a data directory outside the installation directory, which will be used for storing logs, metadata, etc., so that it is to be easily preserved when upgrading Presto. It is defined using the following code −
$ cd $ mkdir data
To view the path where it is located, use the command “pwd”. This location will be assigned in the next node.properties file.
Create an etc directory inside Presto installation directory using the following code −
$ cd presto-server-0.149 $ mkdir etc
This directory will hold configuration files. Let’s create each file one by one.
Presto node properties file contains environmental configuration specific to each node. It is created inside etc directory (etc/node.properties) using the following code −
$ cd etc $ vi node.properties node.environment = production node.id = ffffffff-ffff-ffff-ffff-ffffffffffff node.data-dir = /Users/../workspace/Presto
After making all the changes, save the file, and quit the terminal. Here node.data is the location path of the above created data directory. node.id represents the unique identifier for each node.
Create a file “jvm.config” inside etc directory (etc/jvm.config). This file contains a list of command line options used for launching the Java Virtual Machine.
$ cd etc $ vi jvm.config -server -Xmx16G -XX:+UseG1GC -XX:G1HeapRegionSize = 32M -XX:+UseGCOverheadLimit -XX:+ExplicitGCInvokesConcurrent -XX:+HeapDumpOnOutOfMemoryError -XX:OnOutOfMemoryError = kill -9 %p
After making all the changes, save the file, and quit the terminal.
Create a file “config.properties” inside etc directory(etc/config.properties). This file contains the configuration of Presto server. If you are setting up a single machine for testing, Presto server can function only as the coordination process as defined using the following code −
$ cd etc $ vi config.properties coordinator = true node-scheduler.include-coordinator = true http-server.http.port = 8080 query.max-memory = 5GB query.max-memory-per-node = 1GB discovery-server.enabled = true discovery.uri = http://localhost:8080
coordinator − master node.
node-scheduler.include-coordinator − Allows scheduling work on the coordinator.
http-server.http.port − Specifies the port for the HTTP server.
query.max-memory=5GB − The maximum amount of distributed memory.
query.max-memory-per-node=1GB − The maximum amount of memory per node.
discovery-server.enabled − Presto uses the Discovery service to find all the nodes in the cluster.
discovery.uri − he URI to the Discovery server.
If you are setting up multiple machine Presto server, Presto will function as both coordination and worker process. Use this configuration setting to test Presto server on multiple machines.
$ cd etc $ vi config.properties coordinator = true node-scheduler.include-coordinator = false http-server.http.port = 8080 query.max-memory = 50GB query.max-memory-per-node = 1GB discovery-server.enabled = true discovery.uri = http://localhost:8080
$ cd etc $ vi config.properties coordinator = false http-server.http.port = 8080 query.max-memory = 50GB query.max-memory-per-node = 1GB discovery.uri = http://localhost:8080
Create a file “log.properties” inside etc directory(etc/log.properties). This file contains minimum log level for named logger hierarchies. It is defined using the following code −
$ cd etc $ vi log.properties com.facebook.presto = INFO
Save the file and quit the terminal. Here, four log levels are used such as DEBUG, INFO, WARN and ERROR. Default log level is INFO.
Create a directory “catalog” inside etc directory(etc/catalog). This will be used for mounting data. For example, create etc/catalog/jmx.properties with the following contents to mount the jmx connector as the jmx catalog −
$ cd etc $ mkdir catalog $ cd catalog $ vi jmx.properties connector.name = jmx
Presto can be started using the following command,
$ bin/launcher start
Then you will see the response similar to this,
Started as 840
To launch Presto server, use the following command −
$ bin/launcher run
After successfully launching Presto server, you can find log files in “var/log” directory.
launcher.log − This log is created by the launcher and is connected to the stdout and stderr streams of the server.
server.log − This is the main log file used by Presto.
http-request.log − HTTP request received by the server.
As of now, you have successfully installed Presto configuration settings on your machine. Let’s continue the steps to install Presto CLI.
The Presto CLI provides a terminal-based interactive shell for running queries.
Download the Presto CLI by visiting the following link,
Now “presto-cli-0.149-executable.jar” will be installed on your machine.
After downloading the presto-cli, copy it to the location which you want to run it from. This location may be any node that has network access to the coordinator. First change the name of the Jar file to Presto. Then make it executable with chmod + x command using the following code −
$ mv presto-cli-0.149-executable.jar presto $ chmod +x presto
Now execute CLI using the following command,
./presto --server localhost:8080 --catalog jmx --schema default Here jmx(Java Management Extension) refers to catalog and default referes to schema.
You will see the following response,
Now type “jps” command on your terminal and you will see the running daemons.
After having performed all the executions, you can stop the presto server using the following command −
$ bin/launcher stop
