Configure scp to transfer files between Linux and Unix without a password

How to configure scp File Transfer

To implement scp file transfer between Linux and Unix, you first need to configure scp. By default, scp requires a password. You can complete file transfer between Linux and Unix without entering a password through the following configuration.

Assume that there are 2 Linux, A server, and B server (the ip address is assumed to be xxxx8). You need to transfer files (including directories) from A to B, and install BFagent on. Bkjia user on A and bkjia user on B

Machine

On server
Step 1: Go to/home/bkjia cd/home/bkjia (because we are using bkjia users. If other users are used, go to the directories of other users, such as cd/home/weblogic)
Second, create the. ssh directory, mkdir. ssh
Part 3: Go to the. ssh directory, cd. ssh
Step 4: Execute ssh-keygen-B 1024-t rsa

B server
Step 1: Go to/home/bkjia cd/home/bkjia (because we are using bkjia users. If other users are used, go to the directories of other users, such as cd/home/weblogic)
Second, create the. ssh directory, mkdir. ssh
Part 3: Go to the. ssh directory, cd. ssh
Part 4: Create new files authorized_keys and touch authorized_keys

On server
Step 5: Execute scp-p. ssh/id_rsa.pub bkjia@xxxx.238:/home/bkjia/. ssh/authorized_keys
Place the generated id_rsa.pub to the authorization key file on B server.
Part 6: Test file transmission. You can transmit a directory under/home/bkjia to B.
For example, you can transmit dir001 (which includes multiple files and directories) under/home/bkjia to the/home/bkjia/testdir directory on server B.
Scp-r dir001 bkjia@9.xxxx:/home/bkjia/testdir

B server

Step 5: Go to/home/bkjia/testdir and check the transmitted File
