A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Optional. Install an NFS server

The Container Deployment Foundation requires an NFS server. You can either use the master node as the NFS server or you can set up a separate NFS server. The latter is recommended for production environments.

If you want to use the master node as the NFS server instead, skip this step and go to Install ITOM CDF on the (first) master node.

To install a dedicated NFS server, you can use any operating system that provides NFS. Additionally, the NFS server must meet the following hardware requirements: 16 GB RAM, 8 CPU cores, and 100 GB free disk space.

NFS directories overview

The following NFS directories must be set up during the installation:

Exported NFS file system	Proposed directory	Content
`<CDF_core>`	`/var/vols/itom/core`	CDF related configuration and data files.
`<opsbridge_config>`	`/var/vols/itom/conf`	Operations Bridge Suite related configuration files.
`<opsbridge_data>`	`/var/vols/itom/data`	Operations Bridge Suite related database and runtime files.
`<opsbridge_log>`	`/var/vols/itom/log`	Operations Bridge Suite related log files.

Installation

Follow the steps below for the installation:

Install the NFS server: yum install -y nfs-utils
Create a directory to store the CDF data, and adapt the directory permissions:

mkdir -p <CDF_core>

chown -R 1999:1999 <CDF_core>

Note If you expose a folder that is not named core, specify the exposed folder when installing CDF.
Create directories to store the suite configuration data, the database data, and the log data, and adapt the directory permissions:

mkdir -p <opsbridge_config>

mkdir -p <opsbridge_data>

mkdir -p <opsbridge_log>

chown 1999:1999 <opsbridge_config>

chown 1999:1999 <opsbridge_data>

chown 1999:1999 <opsbridge_log>
Configure the NFS sharing of the CDF and suite directories:

echo "<CDF_core>*(rw,sync,anonuid=1999,anongid=1999,all_squash)" >> /etc/exports

echo "<opsbridge_config> *(rw,sync,anonuid=1999,anongid=1999,all_squash)" >> /etc/exports

echo "<opsbridge_data> *(rw,sync,anonuid=1999,anongid=1999,all_squash)" >> /etc/exports

echo "<opsbridge_log> *(rw,sync,anonuid=1999,anongid=1999,all_squash)" >> /etc/exports
Restart the NFS service to activate the directory sharing:

exportfs -ra

Tip Do the following to check what has been exported:

Disable the firewall on the NFS server.
Restart the NFS service by running the following commands:

systemctl restart rpcbind systemctl enable rpcbind systemctl restart nfs-server systemctl enable nfs-server
Run exportfs
