[Shell instance]--a script implementation to batch copy files to multiple servers (Nmap, SCP)

Practice Environment:

(1) All servers will shut down firewalls and SELinux
(2) The root password for all servers is set to AIXOCM
(3) All servers are 10.0.100.* network segments and are guaranteed to communicate with other hosts
(4) All servers ensure that the SSHD service is started (open the default 22 port)

The script requires implementation:

Package the file with the Conf extension in the native/etc directory to tar.bz2, and then copy the file to the 10.0.100.1-->10.0.100.254 address segment for all open hosts with the/tmp/sjjy/file. You do not need to enter a password manually when using SCP replication.

The approximate idea of the script:

(1) Tar_etc () function: Implement the packaging of all *.conf directories under/etc and determine if the package is successful.

(2) Nmap_ip () function: Implements scanning of hosts that are turned on. Implemented with nmap command. and write these host IPs to the/mydate/ip.txt file.

(3) Scp_ip () function: implements the sending of a compressed package to the specified directory of each host. The input implemented using the #expect command.
