To install Zephyr Enterprise on cluster nodes, you need to perform the following steps:

1.

...

• MySQL (make sure the ITCC and Dversion databases are not installed)

• Microsoft SQL Server

• Oracle Database

...

Connect to an external database
2. Install

& configure Elasticsearch
3. Install Zephyr Enterprise on your

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

...

Install Zephyr on any drive other than drive C: to avoid permission issues, as administrator permissions may be required to work with this drive.

nodes

...

Installation steps:

Install Zephyr Enterprise on nodes. The installation steps on the first node differ from the steps you perform on the other nodes.

1. To install Zephyr Enterprise on the first node:

Expand
title On Windows
Follow the installation steps for Windows described in the Installing Zephyr Server section. Note During the installation, select the Data Center deployment option: Image Removed

Expand
title On Linux
Follow the installation steps for Linux described in the Install Zephyr section. Note During the installation, choose Data Center deployment as the deployment type: Image Removed

2. After you install Zephyr, stop the node.

3. Install Zephyr Enterprise on another node. The way you do this depends on your operating system:

...

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

4

...

You can use any number of nodes. If you want to add more nodes, repeat steps 3-4.

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

...

In the file, find the following line:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

and replace it with the following:

...

...

.

...

Expand
title zephyr/tomcat/conf/web.xml
In the file, before the web-app tag, add the tag <distributable />: Image Removed

...

7. Make the following changes in the cluster.properties file:

• Remove the following lines:

#unique identifier for the cluster node
cluster.aws.enable=false
HAZELCAST_PASSWORD=huser
HAZELCAST_USERNAME=hpass

• Update the following information:

cluster.key=node1 (this should be a unique name of the node)
cluster.node.1.key=node1
cluster.node.1.url=172.17.18.141 (the IP address of node 1)
cluster.node.count=4
cluster.node.2.key=node2
cluster.node.2.url= 172.17.18.157(the IP address of node 2)
cluster.node.3.key=node3
cluster.node.3.url=172.17.18.223 (the IP address of node 3)
cluster.node.4.key=node4
cluster.node.4.url=172.17.18.201 (the IP address of node 4)

...

cluster.key=node2 (this should be a unique name of the node)
cluster.node.1.key=node1
cluster.node.1.url=172.17.18.141 (the IP address of node 1)
cluster.node.count=4
cluster.node.2.key=node2
cluster.node.2.url= 172.17.18.157(the IP address of node 2)
cluster.node.3.key=node3
cluster.node.3.url=172.17.18.223 (the IP address of node 3)
cluster.node.4.key=node4
cluster.node.4.url=172.17.18.201 (the IP address of node 4)

8. Start the first node where you installed Zephyr by using the hostname or the IP address of the machine. Zephyr will start on it. After Zephyr is launched, the HAZELCAST_USERNAME and HAZELCAST_PASSWORD values will be generated in the zephyr/tomcat/webapps/flex/WEB-INF/classes/cluster.properties file.

9. Copy the HAZELCAST_USERNAME and HAZELCAST_PASSWORD values and paste them to the zephyr/tomcat/webapps/flex/WEB-INF/classes/cluster.properties file on the other nodes.

Share a folder by using NAS (network-attached storage) or a similar device:

a

...

2. On all the nodes, open the

Program Files\Zephyr\tomcat\webapps\flex\WEB-INF\classes\jdbc.properties file, find the line

ZEPHYR_DATA = C:/Program Files/Zephyr/zephyrdata

...

shared

...

ZEPHYR_DATA= //192.168.11.141/zephyrdata

...

Install the NFS (Network File System) server and client on CentOS 7. To do that:

On the server side:

1. Install the required NFS packages by running the following command:

 yum install nfs-utils

 2. Create the Zephyrdata directory and allow access to it:

chmod -R 777 /homeZephyrdata

...

directory

...

3. Start the following services and add them to the Boot Menu:

systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable nfs-lock
systemctl enable nfs-idmap
systemctl start rpcbind
systemctl start nfs-server
systemctl start nfs-lock
systemctl start nfs-idmap

4. Open exports for editing –

sudo gedit /etc/exports

– and type the following:

/home/zephyrdata 192.168.0.101(rw,sync,no_root_squash,no_all_squash)
/home/zephyrdata 192.168.0.102(rw,sync,no_root_squash,no_all_squash)

...

...

 192.168.0.101 and 192.168.102 are the IP addresses of the clients.

5. Start the NFS service by running the following command:

 systemctl restart nfs-server

 6. Add the NFS service override in the CentOS 7.0 firewall-cmd public zone service:

firewall-cmd --permanent --zone=public --add-service=nfs
firewall-cmd –reload

The NFS server is ready to work.

On the client side:

1. Install the required NFS packages by running the following command:

yum install nfs-utils

2. Start the following services and add them to the Boot Menu:

systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable nfs-lock
systemctl enable nfs-idmap
systemctl start rpcbind
systemctl start nfs-server
systemctl start nfs-lock
systemctl start nfs-idmap

3. Mount the NFS share on the client machine by running the command below:

mount -t nfs 192.168.0.100:/home/zephyrdata  /home/node1/zephyrdata

4. Change the ZEPHYR_DATA path to the mounted path for all the nodes in the

opt\Zephyr\tomcat\webapps\flex\WEB-INF\classes\jdbc.propeties file.

For example:

ZEPHYR_DATA = /home/node1/zephyrdata

5. You are connected to the NFS share. Now you can crosscheck it by running the following command:

df -kh

5. Configure load balancer
6. Bring up the whole system
