- SAPRouter software package downloaded from the SAP Support Portal

Step 1: Download SAPRouter:

Download the SAPRouter software package from the SAP Support Portal. Ensure that you download the correct version for your operating system.

Step 2: Extract the SAPRouter Package:

Transfer the downloaded SAPRouter package to your Linux server. Use the following command to extract the package:

tar -xvf saprouter_<version>_linux_x86_64.tar.gz

Step 3: Create a Directory for SAPRouter:

Create a directory to store the SAPRouter files. You can use the following command to create the directory:

mkdir /usr/sap/saprouter

Step 4: Copy SAPRouter Files:

Copy the extracted SAPRouter files to the newly created directory:

cp -R <path_to_extracted_files>/saprouter /usr/sap/saprouter

Step 5: Create a Configuration File:

Create a configuration file named `saprouter.ini` in the `/usr/sap/saprouter` directory. Here's a basic example of the configuration file:

# SAProuter Configuration File

version = 39

httpport = 81

tracefile = /usr/sap/saprouter/saprouter.trc

authid = *

permit = *

Step 6: Set Permissions:

Ensure that the SAPRouter binary and configuration files have the correct permissions:

chmod 755 /usr/sap/saprouter/saprouter

chmod 644 /usr/sap/saprouter/saprouter.ini

Step 7: Start SAPRouter:

Start the SAPRouter using the following command:

/usr/sap/saprouter/saprouter -r -R /usr/sap/saprouter/saprouter.ini

Step 8: Verify SAPRouter Status:

Verify that SAPRouter is running and listening on the specified port (e.g., 81):

netstat -tuln | grep 81

Step 9: Configure Firewall:

Configure your firewall to allow incoming and outgoing traffic on the SAPRouter port (e.g., 81) to ensure proper communication.

Step 10: Configure SAP Systems:

Update the `secinfo` file of your SAP systems to include the SAPRouter details for communication through the SAPRouter.

Overall information:

By following these steps, you can successfully install SAPRouter on your Linux server. This will help secure communication between your SAP systems and the internet, ensuring the integrity and confidentiality of your SAP landscape.
