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:
OpenJDK 17.0.10 (recommended) - see the installation instructions
Oracle JDK 17.0.10 - download and install according to the Oracle documentation.
Download MySQL Connector.
Upload Zephyr License: The Zephyr installer requires access to the license file provided. It will need to be first uploaded to the file system of the server.
Upload the MySQL Connector: The Zephyr installer requires access to the MySQL connector jar file downloaded. It will need to be first uploaded to the file system of the server.
Set ulimit in Linux: increase ulimit 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
- WGETsudo yum install -y perl-Digest-SHA
- SHASUMsudo yum -y install epel-release
- EPEL repo installsudo yum repolist
- update the repo listsudo 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):
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_x.x_xxx_setup_iRev_xxx.sh -VzSkipStartupData=true
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.
Write down the IP address of each node – you will need them at the next step.
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
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.
