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

1. Create a shared folder with read/write access in NAS (network-attached storage).

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 /home/ZephyrdatahomeZephyrdata

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:

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 rpcbindsystemctl 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

In the file, find the following line:

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

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

and replace it with the following:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"channelSendOptions="8">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
<Channel className="org.apache.catalina.tribes.group.GroupChannel">
<Membership className="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.22"
port="45564"
frequency="500"
dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="4000"
autoBind="100"
selectorTimeout="5000"
maxThreads="6"/>
<Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
</Sender>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
filter=""/>
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>

1. In this file, find the line –

<member>127.0.0.1:5702</member>

– and add the IP addresses of all the nodes instead of 127.0.0.1. For example:

<member>172.17.18.141:5702</member>
<member>172.17.18.157:5702</member>
<member>172.17.18.223:5702</member>
<member>172.17.18.201:5702</member>

2. Find the string line –

<interface>127.0.0.1</interface>

– and replace it with an IP address that has an asterisk instead of the last component. For example:

<interface>172.17.18.*</interface>
