在管理机生成密钥对
ssh-keygen -t rsa 一路回车
去交互式的脚本
#!/usr/bin/expect
set IP [lindex $argv 0]
set PASSWORD 123123
set timeout 10
spawn ssh-copy-id root@$IP
expect {
"yes/no" {send "yes\r";exp_continue}
"password:" {send "$PASSWORD\r"}
}
interact
调用上面的脚本实现自动分发密钥
#!/bin/bash
#
yum -y install expect
for I in {151..154}
do
/root/fenfamiyao.sh 192.168.100.$I
done
使用它以下脚本完成小型批量管理分发与执行
#!/bin/bash
#
. /etc/init.d/functions
for I in {151..154}
do
#ssh [email protected].$I $1 &> /dev/null
rsync -zavH $1 [email protected].$I:/root/ &> /dev/null
if [ $? -eq 0 ]; then
action "执行192.168.100.$I" /bin/true
else
action "执行192.168.100.$I" /bin/false
fi
done
