You can installone of the following database management systems on any computer where Zephyr is not installed:

Note

You must have a connector JAR file for your MySQL, Microsoft SQL Server or Oracle database.

...

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.

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

1. Create a shared folder with read/write access in NAS.

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

and replace the C:/Program Files/Zephyr part with the IP address of the NAS shared folder. For example:

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

Info

If you installed Zephyr as a non-root user, install the NFS server and client as a root user and create the Zephyrdata directory as a non-root user.

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)

Info

 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

Info

192.168.0.100 is the IP address of the server.

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

Now you can use your nodes.
