4. Set Up a Shared Directory

A shared directory in a cluster is a shared folder where attachments are stored. In a cluster environment, this folder must be shared with write permissions. A folder is shared on NAS (network-attached storage) or similar devices, and then it can be accessed by the users working with Zephyr running on cluster nodes.

To set up a shared directory, do the following:

On Windows:

1. Create a shared folder with read and write access on NAS.

2. On all Zephyr nodes, open the Zephyr folder\tomcat\webapps\flex\WEB-INF\classes\jdbc.properties file, find the following line:

ZEPHYR_DATA = Zephyr folder/zephyrdata

and replace the Zephyr folder part with the IP address of your NAS. For example:

ZEPHYR_DATA= //192.168.11.141/zephyrdata

Now, you can use your shared folder.

On Linux:

Install the NFS (Network File System) server and client on CentOS 7.

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

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)

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 (on each Zephyr node):

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 /<zephyrlocation>/zephyrdata

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

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

For example:

ZEPHYR_DATA = <zephyrlocation>/zephyrdata

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

df -kh
