Server installation - Storm Streaming Server

There are two ways on how to install Storm Streaming Server on your machine - you can either download files manually and start the server though provided shell scripts, or use Docker image instead. The first method requires a working JVM, as not all systems come with it preinstalled. A detailed tutorial on how to do this can be found in our Java Installation Guide.

Alternatively a Docker container can be used instead, since all Storm Streaming Server builds come with dedicated Docker images. We have prepared a complete tutorial for Docker installation and reconfiguration, that can be found in Docker Installation Guide section.

Manual installation

Storm Streaming Server can be download from My Products / Download page and comes as the compressed zip file. Please uncompress it into a desired location (we suggest something within /home or /srv directories). The package contains:

Manual installation - Starting server

1. On Linux-based and MacOS X operating system

   In order to start the server, you can edit scripts/start.sh script. It’s very short and simple:

                                   
   #!/bin/sh
   pkill -9 -f "StormStreamingServer.jar"
   echo Shutting down old instances ... 3
   sleep 1
   echo Shutting down old instances ... 2
   sleep 1
   echo Shutting down old instances ... 1
   sleep 1
   pkill -9 -f "StormStreamingServer.jar"
   echo Shutting down old instances ... 0
   sleep 1
   echo Staring new Java App
   java -server -Xmx128g -Xms32g -XX:+UseG1GC -XX:MaxGCPauseMillis=100 -jar "/home/storm/StormStreamingServer.jar" -configRootDIR /home/storm &
                               

   The script will automatically kill all instances of Storm sever and start a new one. We’ll have to edit some parameters before we can properly launch the server.

   Parameter	Description
   -Xmx128g	JVM parameter controlling the maximum amount of RAM memory can be allocated to JVM. The amount shouldn’t exceed ¾ of the total RAM In your system. You can replace memory value with any number according to this pattern: -XmxYZ, where Y is the number of Z (g – gigabytes, m -megabytes)
   -Xms32g	JVM parameter controlling the minimal amount of RAM memory allocated to the JVM. This number shouldn’t be lower than ¼ of the -Xmx parameter
   -jar “<PATH_TO_JAR_FILE>”	This is the direct path to the jar file
   -configRootDIR <PATH_TO_MAIN_FOLDER>	This parameter points to the main folder of the server (containing license and config folders)
   &	This option will keep the server running in the background

2. On Windows-based operating system

   In order to start the server you can edit scripts/start.bash script. It’s very short and simple:

                                   
   taskkill /f /t /im java.exe
   echo Shutting down old instances ... 3
   sleep 1
   echo Shutting down old instances ... 2
   sleep 1
   echo Shutting down old instances ... 1
   sleep 1
   taskkill /f /t /im java.exe
   echo Shutting down old instances ... 0
   sleep 1
   print Staring new Java App
   START /B java -Xmx128g -Xms32g -jar C:\Program Files\Storm\StormStreamingServer.jar -configRootDIR C:\Program Files\Storm
                               

   The script will automatically kill all instances of Storm sever and start a new one. We’ll have to edit some parameters before we can properly launch the server.

   Parameter	Description
   -Xmx128g	JVM parameter controlling the maximum amount of RAM memory can be allocated to JVM. The amount shouldn’t exceed ¾ of total RAM in your system. You can replace memory value with any number according to this pattern: -XmxYZ, where Y is the number of Z (g – gigabytes, m -megabytes)
   -Xms32g	JVM parameter controlling the minimal amount of RAM memory allocated to the JVM. This number shouldn’t be lower than ¼ of the -Xmx parameter
   -jar “<PATH_TO_JAR_FILE>”	This is the direct path to the jar file
   -configRootDIR <PATH_TO_MAIN_FOLDER>	This parameter points to the main folder of the server (containing license and config folders)
   START /B	This option will keep the server running in the background

Docker installation

This is an alternative method to manual installation. In order to download storm image, please use the following command (linux, mac os terminal):

                        
docker run -it -d --name StormStreamingServer --hostname StormStreamingServer -e "JAVA_OPTS=-Xmx16G" -p 1935:1935 -p 80:8080 -p 443:8443 -v /home/storm/config:/opt/storm/data docker.stormstreaming.com/stormstreamingserver/stormstreamingserver:latest
                    

Commands explanation:

Server preferences

Before StormStreamingServer can be started for the first time, some modifications to the preferences.xml must be made prior. For Docker images it will be auto-generated upon first container launch, but must be edited nonetheless.

1. Adding server license - a proper license key must be added to the preferences.xml file. You can obtain your serial code on the My Products / Download page, within your account.

                                   
   <License key="YOUR-SERIAL-CODE-GOES-HERE" />
                               

2. Configuring Domain - the server must be aware of the main domain to properly serve some types of requests.

                                   
   <Domain>sub1.mydomain.com</Domain>
                               

3. SSL Certificate and password - a properly configure JKS file and password must be provided to enable SSL Connection. A detailed guide on how to create your JKS file can be found in our SSL Configuration guide.

                                   
   <Certificate>
       <path>/etc/ssl/private/mydomain.jks</path>
       <password>mypassword</password>
   </Certificate>
                               

Log file location

One more thing that needs to be done is defining the log files directory. In order to do it, please edit log4j.xml file and search for appender name="file" tag.

One of the parameters will show the directory for the logs.

                                
<param name="file" value="H:/StormServer/log/log.log" />
