Configuring Mapping Between Hostnames and IP Addresses

Scenarios

During the SAP installation, installation programs use hostnames for communication. Therefore, you must configure the mapping between hostnames and IP addresses.

Procedure

1. Log in to the NAT server as user root using the key file. Then, use SSH to switch to SAP Business One nodes.
2. Run the following command to open the hosts file:

   vi /etc/hosts

3. Write the names and IP addresses of all SAP nodes into the hosts file.
   • IP-Address is the IP address of the server or client plane in the single-node deployment mode.
   • Both Full-Qualified-Hostname and Short-Hostname are the server name, for example, businessone001.

   The format is IP-Address Full-Qualified-Hostname Short-Hostname.

   

   In an SAP system, you must write the mapping between all SAP node IP addresses and node names into the hosts file.

4. You can copy the hosts configuration file to other SAP nodes to complete the configuration on these SAP nodes.
