Cloud connector installation on Linux :

Cloud connector installation 

in this blog, we will explained the Cloud connector installation on Linux , cloud connector Start and Cloud connector Stop. Cloud connector over view details. 
We have separated cloud connector over view in below steps:

Cloud Connector over view :

1. Introducing the Cloud Connector
2. Installing the Cloud Connector
3. Configuring the Cloud Connector
4. Using the Cloud Connector
5. Administering the Cloud Connector

1. Introducing the Cloud Connector

# Purpose of the cloud connector:

• Secure connection between the cloud and on promise application.
• Service channels can allow on promise database tools to access specific SAP BTP Services.
• Cloud connector software easy to downloaded from sap development tools web site
• Installed in on promise environment and run windows and Linux. Easy install and configuration the Cloud connector..

# Use Cases for Cloud Connector

• single cloud system is connect to  single on-premise system.
• Multiple cloud systems is connect to multiple on-premise systems.
• One Cloud Connector is connect to multiple SAP BTP subaccounts.
• Multiple Cloud Connectors is connect to the one or more the  SAP BTP subaccounts.

# SAP HANA Cloud database running is on SAP BTP Account.

• We can use tools like  database management tools from our on-premise landscape to connect to SAP HANA Cloud databases.
• we can Use Data Services to provision data from the on-premise database connect to the cloud or vice versa.
• we can Use on-premise reporting tools like Business Objects connect to access data in SAP HANA Cloud.
• we can Use RFC calls Connection from on-premise systems to the  SAP BTP ABAP environment.
• Establish the  TCP connection to the service in a Cabernets cluster on the SAP BTP.

2. Cloud connector installation on Linux Prerequisites :

Prerequisites
• Cloud connector will support window, Linux and macos.
• Cloud Connector requires a JDK
• SAP JVM 64-bit, version 8
• SapMachine 64-bit, version 17.
• Oracle JDK 64-bit, version 8.
• The minimum disk space is required for the Cloud Connector installation.
• The Cloud Connector writes the logs on the configuration files, audit log files, and trace files at runtime. As  SAP recommendation, we can  reserve between 1 and 20 GB of disk space of this files.

Sizing of the Cloud Connector Master Instance

Cloud Connector Installation model:

• Goto Media from sap development tool, goto cloud connector and download the media based on Operation version.
• We can use any option for the installation modes for install  The Cloud Connector :

1. Portable version
2. Installer version

Portable Version on Linux

• Need to  the Extract the tar.gz file  on the  concern location. we can use below command for extract the tar file command:
• tar –x sapcc-<version>-linux-<platform>.tar.gz.
Go to the concern directory and Execute the go.sh script for the start the Cloud Connector installation.

Installer Version on Linux

• Extract the sapcc-<version>-linux-<platform>.zip archive to the Concern Location by using the command
• unzip sapcc-<version>-linux-<platform>.zip
• Go to the concern location and Execute the below command as the root user
• rpm -i com.sap.scc-ui-<version>. <arch>.rpm

 Start, stop & restart the process Cloud Connector:

• open a CMD and use the below commands for start,stop & restart, which require root permissions:
• service scc_daemon start stop | restart (on System V distributions)

Cloud connector installation on Linux :

Cloud connector installation on Linux commands:.

• need root permission user for cloud connector installation.
• Download the media from development tools and move to concern location.
• Required Media for installation.
• Example:
       1. sapcc-2.15.2-linux-x64.zip
       2. sapjvm-8_1_903- linux-x64.rpm
• install the jvm files. Execute the below command for JVM installation.
• rpm -i sapjvm-8_1_903- linux-x64.rpm     and  unzip/extract the cloud connector.
• unzip sapcc-2.15.2-linux-x64.zip
• After uncar the zip file, some folders is created. Then execute the rpm command for installation.                            rpm -i file
• Once installation has completed, check the connector status.
• systemctl start/stop/restart scc_daemon
• systemctl status scc_daemon
• systemctl start scc_daemon
• systemctl stop scc_daemon

3. Configuring the Cloud Connector

• Cloud Connector Logon: https://localhosts: 8443 User: Administrator Password: manage (default)
• After changing the password, need to exchange the ui certificate.
• Goto Configuration then click on user interface. Click generates the certificate.
• Mention required details like DNS, Organization and country then generate the certificate and download.
• Once singing is completed, then import the certificate in cloud connector.
• Restart the cloud connector.
• Check url status.

4 Managing Subaccounts

• Select the subaccount and note down the sub- account id
• Goto define subaccount–fill the all details. region, subaccount, user and password then save.
• Secure tunnel connection established cloud connector AND SAP btp ACCOUNT sub.

5 Configuring Access Control

• Using below protocols, To allow your cloud applications to access a certain on-premise system on the intranet.

1.HTTP
2.RFC
3. LDAP
4.TCP

• Login to the cloud connector Administrator.
• Goto Configuration then selects the On Promise.
• Click on Copy UI certificate and reuse. Then click on overwrite.
• Click Add (+) Chose the x509 certificate.
• Browse the certificate, then select the certificate and save.
• Add system: click cloud to on promise option then goto Access control and click + option.
• Chose ABAP System, protocol HTTP, internal/virtual host and ports. Click on finish.
• System has added successfully and click (+) adding the resource.
• URL path: /sap and Access policy: path and all sub paths and save. So resource is added.
• Go to Connectivity —-Chose cloud connector —Check connection and resource status.
• Successfully configured the Cloud to on promise connections.

4. Connect On-Premise to SAP BTP Applications

Cloud to on promise:

• Login on sap system and check fiori has installed or not.
• Se80–check ZFIORI repository.
• Goto Cloud connector administrator then selects the Cloud to on promise options. Check resources status.

Chose sub account then select the destination.

• Add new destination/edit the existing destination details.
• Select the instance and subscriptions and goto applications.
• Click on applications and chose menu options then select the terminal –New terminal
• mention module details: rpm run deploy-config
• Chose ABAP and destination. Enter repository and packages. Then start the deploy ment.
• Once deployment has completed, Login SAP System then activate the packages (BSP Application). * now fiori application deployment completed.

5. Cloud connector monitoring:

* 3 tolls for monitor the cloud connector.
1. OS Command
2. SAP BP Cockpit
3. Cloud connector UI
• OS command for monitor the cloud connector
• service scc_daemon status
• systemctl status scc_daemon
• Goto Cloud connector administrator–Check CPU, HARDWARE and space utilizations.

6. Configuring High Availability

• install cloud connector master and shadow
• Connect shadow instance to the master.
• Master instance enable the HA.
• on shadow instance, select the shadow as instance type.
• On the shadow instance, provide connection information for the master.
• On the master instance, confirm that the shadow is connected.
