/Usr/bin/ssh-keygen-t rsa

Then on the host that needs to be distributed in batches

Touch ~ /. Ssh/authorized_keys

Ssh 192.168.1.20 cat ~ /. Ssh/id_rsa.pub> ~ /. Ssh/authorized_keys

Note: 192.168.1.20 is the IP address of the distribution host.

The authenticity of host 'linux1 (192.168.1.100) 'can't be established.

RSA key fingerprint is 2f: cc: a1: 4f: 2b: 67: 01: 6a: d1: 9e: 0b: AB: c8: 9e: 57: a1.

Oracle @ linux1's password: xxxxx

Run

Chmod 600 ~ /. Ssh/authorized_keys

Verify on the distribution host

Ssh 192.168.1.19 hostname

RS9

Common scp. sh files on distribution hosts

Distribute files from the distribution host 192.168.1.20 to 192.168.1.19 and 192.168.1.10

Scp-r/usr/local/adsit/webapps/preroll/WEB-INF/classes root@192.168.1.19:/home/adsit/

Scp-r/usr/local/adsit/webapps/preroll/WEB-INF/classes root@192.168.1.10:/home/adsit/

Run scp. sh on the distribution host to implement the copy function.
