How send files from Jenkins(residing in EC2) to another EC2 machine

o establish connectivity between two EC2 instances using SSH or FTP for continuous deployment from Jenkins, you can follow these steps:

Configure SSH: a. Ensure that SSH is installed on both the source and destination EC2 instances. By default, most Linux distributions have SSH preinstalled. b. Generate an SSH key pair on the source EC2 instance if you haven't already. You can use the ssh-keygen command to generate the keys. c. Copy the public key (id_rsa.pub) from the source EC2 instance to the destination EC2 instance. You can use the ssh-copy-id command to achieve this:

ssh-copy-id -i ~/.ssh/id_rsa.pub <user>@<destination_ec2_public_ip>

Replace <user> with the username to access the destination EC2 instance, and <destination_ec2_public_ip> with the public IP address of the destination EC2 instance. d. Test the SSH connection by running the following command on the source EC2 instance:

ssh <user>@<destination_ec2_public_ip>

If the connection is successful, you should be able to log in to the destination EC2 instance without entering a password.

Configure FTP (optional): a. Install an FTP server on the destination EC2 instance. One popular option is vsftpd (Very Secure FTP Daemon). b. Configure the FTP server to allow connections from the source EC2 instance by adding the source EC2 instance's IP address to the FTP server's configuration. c. Test the FTP connection by running an FTP client on the source EC2 instance and connecting to the FTP server running on the destination EC2 instance.

Update Jenkins configuration: a. Install the necessary plugins in Jenkins to support SSH or FTP operations. For SSH, you can use the "Publish Over SSH" plugin, and for FTP, you can use the "Publish Over FTP" plugin. b. Configure the SSH or FTP plugin in Jenkins with the connection details of the destination EC2 instance, such as IP address, username, and private key (for SSH) or FTP credentials (for FTP). c. Create a Jenkins job or pipeline that includes the necessary build and deployment steps. Use the SSH or FTP plugin to execute commands or transfer files between the EC2 instances during the deployment process.
