Client: kkweb@192.168.1.10
Server: kkdev@192.168.1.11

Implementation idea: Generate public and private key files through SSH, save the public key file to the server, and implement key verification in scripts without interactive password input, and realize automated script execution.

Generate SSH keys
$ ssh-keygen

Entering all the way, SSH private key file (id_rsa) and public key file (id_rsa.pub) will be generated in the home directory of kkweb user, as shown below:

2. Copy id_rsa.pub to the kkdev@192.168.1.11 directory and change the file name to authorized_keys (interlaced writing by multiple hosts is sufficient), as shown below

3. Run the script (login.sh) under the user kkweb@192.168.1.10: 


#!/bin/bash
sftp kkdev@192.168.1.11<<EOF
-get /data/kkweb/kkweb_dev/build/ROOT.war /home/dev/
quit
EOF


You can download ROOT.war@192.168.1.11 to 192.168.1.10:/home/dev/ directory
