On Linux

Important

When installing Zephyr on your nodes, keep in mind the following:

  • Use the same Zephyr version and build on all the nodes.

  • Zephyr installed on all the nodes must have the same license.

Prerequisites (apply to each node)

  • Make sure the computer meets the system requirements.

  • Ensure you have the license file (license.lic) and any plugin license files that were provided.

  • Download the installation file of Zephyr Enterprise for Linux.

  • Download and install JDK. Use one of the following:

  • Download MySQL Connector.

  • Upload Zephyr License: The Zephyr installer requires access to the license file provided. It must first be uploaded to the server's file system.

  • Upload the MySQL Connector: The Zephyr installer requires access to the MySQL connector jar file downloaded. It will first need to be uploaded to the server's file system.

  • Set limit in Linux: increase limit on the server to 65535.

Base node creation

If you have a new node that is not yet configured, do the following:

  1. Create a Linux EC2 instance, Name-BASE-01, and configure basic parameters:

    • Assign an elastic IP.

    • Log in to the instance using your .pem key.

    • Create the user zephyr and the zephyr password:

      sudo adduser zephyr

      sudo passwd zephyr

    • Add the user to the root group and log in as the zephyr user:

      sudo usermod -a -G wheel zephyr

      su - zephyr

    • Add your ssh keys to user zephyr:

      sudo yum install openssh-server

      ssh-keygen

      vi /.ssh/authorized_keys

      #add necessary public keys to the server

  2. Install the following packages:

    sudo yum install wget - WGET

    sudo yum install -y perl-Digest-SHA - SHASUM

    sudo yum -y install epel-release - EPEL repo install

    sudo yum repolist - update the repo list

    sudo yum install dpkg-devel dpkg-dev - DPKG

  3. Create an Amazon Machine Image from this instance: Name-BaseCluster-AMI.

Zephyr installation steps

1. Install Zephyr Enterprise on the first node (the installation steps on the first node differ from the steps you perform on the other nodes):

Installation steps on the first node

Important

When installing Zephyr on your nodes, keep in mind the following:

  • Use the same Zephyr version and build on all the nodes.

  • Zephyr installed on all the nodes must have the same license.

  1. Ensure the installation file has proper permissions to be executed:

    chmod +x zephyr_(Build Number)_linux_setup.sh

  2. Launch the installation file with the -c command line option as shown below, and ensure you launch it as sudo or root:

    sudo ./zephyr_(Build Number)_linux_setup.sh

  3. You will be prompted to continue with the installation. Choose OK to continue:

    Starting Installer...
This will install Zephyr X.X on your computer
OK [o, Enter], Cancel [c]

  4. You may be prompted to choose between a new installation and upgrading. Choose Install.

    Choose type:
Install [1, Enter], Upgrade [2]

  5. You will be prompted to confirm your system meets the Zephyr Server requirements. Please make sure your system meets the requirements before proceeding:

    Requirements Server OS: RedHat Enterprise CentOS Ubuntu/Debian SUSE/openSUSE CPU: Quad-core CPU Intel Pentium or AMD Opteron (2Ghz or higher) RAM: Minimum 16GB; Preferred 16GB Disk Space: At least 5GB Free Networking: Wired Ethernet Static IP address If Firewall exists, please allow ports 80, 443, 8005, 8009 , 3306 Account: Superuser (root) access to the machine Installer and services need to be installed as "root"

  6. Agree to the Zephyr EULA:

  7. Press the Enter key until you see the following, then press 1 to agree to the terms:

    I accept the terms of this license agreement [1], I do not accept the terms of this license agreement [2, Enter]

  8. Specify the destination location to place the Zephyr home directory:

    Select Destination Location Setup will install Zephyr into the following folder. To continue click Next. If you would like to select a different folder, click Browse [/usr/local/zephyr]

  9. Choose the installation type Data Center deployment:

    Choose deployment type:
Server deployment [1, Enter], Data Center deployment [2]

  10. Locate your license file:

    License File License Key File: [/home/zephyr/license.lic]

  11. Choose a port to run Zephyr on. By default, Zephyr runs on port 80 (for a root user) and port 1024 (for a non-root user):

    Customization Server Port : [80]

  12. Choose a Tomcat Server Shutdown Port. We recommend that you leave the default port for it:

    Tomcat Server Shutdown Port:

    [8005]

  13. You will be prompted to choose a database system. Choose MySQL:

    Note: If you had just uninstalled. Please wait a few minutes for the port to get free and try again. Configure Database Database Type: MySQL [1, Enter]

  14. Specify the username you use to connect to the database:

    Database Character Set: utf8

    Username:[]

  15. Specify the password you use to connect to the database:

    Password: []

  16. Specify the database connection string:

    Database URL Configuration:

    Sample URL: jdbc:mysql://localhost:3306/Database URL:[]

  17. Specify the connection string for Elasticsearch you configured earlier. By default, Elasticsearch will bind to the IP configured in the elasticsearch.yml file edited earlier in the installation instructions. For example 192.168.56.101:9300:

    Configure Elasticsearch

    Enter the hostname or IP address and port used by Elasticsearch. For example: localhost:9300.Multiple Elasticsearch nodes should be separated by comma. For example: localhost:9300,localhost:9301ES Host URL[]

  18. Zephyr will now install the required files:

    Extracting files ..

    # ************************************************************

  19. After the installation is complete, you will see the following:

    ZephyrService.sh may or may not start automatically. Please check and start manually if not started.

    Done! Zephyr x.x has now been installed on your computer. Zephyr Desktop will now be launched automatically.You can access additional help from the Zephyr installation.Click Finish to exit setup.Launch Zephyr Desktop?Yes [y, Enter], No [n]

  20. Choose No for now.

2. After you install Zephyr, make sure it is up and running, and then stop the node.

3. Install Zephyr Enterprise on another node:

  • Perform the steps described in Prerequisites and in Base node creation, if needed.

  • Open the terminal and run the following command:

    sh zephyr_xxx_setup_iRev_xxx.sh -VzSkipStartupData=true

    Important

    The command is case-sensitive.

4. Once the installation is complete, stop the node.

You can use any number of nodes. If you want to add more nodes, repeat steps 3-4, at that, keep in mind that:

  • The nodes can be in different regions, but all of them must be in the same time zone.

  • The node IPs must be on the same subnet.

Important

Write down the IP address of each node – you will need them at the next step.

Warning

After installing Zephyr on Java virtual machines, you need to allocate memory for the Tomcat server and set the amount of native memory that can be used for class metadata. To do that, open the file zephyr-directory/tomcat/bin/setenv.sh on each node and configure the line below in the following way:

export JAVA_OPTS="-server -Xms2048m -Xmx4096m -XX:MaxMetaspaceSize=512m

Note: The -Xms value must be 50% of RAM, the -Xmx value must be 75% of RAM. For example, if you have 16 GB of RAM on your machine, we recommend that you specify the following values:

export JAVA_OPTS="-server -Xms8192m -Xmx12288m -XX:MaxMetaspaceSize=512m

Important: Do not run any services or applications on the nodes where Zephyr is running, as they consume VM resources as well.

5. After you install Zephyr Enterprise on all the nodes, you need to modify the following file on each node:

<Zephyr Directory>/tomcat/webapps/flex/WEB-INF/classes/hazelcast.properties

In this file, find the following lines and change the values as shown below:

zephyr.hz.cluster.enabled=false - set it to true.

zephyr.hz.cluster.name=zephyr-hazelcast-cluster - specify a unique name for each cluster, for example, zephyr-hazelcast-cluster_smartbear.

zephyr.hz.interfaces.enabled=false - set to true.

zephyr.hz.interface=127.0.0.1 - This is the IP of the IP interface. Replace it with an IP address that has asterisks instead of the last two components. For example: zephyr.hz.interface= 192.168.*.*

zephyr.hz.tcp-ip.enabled=false - set it to true.

zephyr.hz.members=127.0.0.1 - specify the IP addresses and port number of each node separated by a comma. For example: zephyr.hz.members=192.168.0.1:5701,192.168.0.2:5701

6. Start Zephyr on the first node by using the following commands:

cd /usr/local/zephyr/tomcat/bin
sudo ./startup.sh

Tip

To stop Zephyr, use the commands below:

cd /usr/local/zephyr/tomcat/bin

sudo ./shutdown.sh

When Zephyr starts, you will see the following line in the log file zephyrlocation/tomcat/logs/thedinc.log:

***************** Zephyr Started *****************

7. Start the other nodes.

8. Stop all the nodes.

Now you can set up a shared folder. To learn how to do that, click Next Step below.
