二、通过shell循环判断主机在线

一、准备工作安装expect装备公钥
二、通过shell循环判断主机在线
#!/bin/bash #脚本编写
#创建一个IP地址文件
ip.txt
#使用for循环ping测试主机是否在线
for i in {3..254}
do{ip192.168.151.$iping -c1 -W1 $ip /dev/nullif [ $? -eq 0 ]thenecho $ip ip.txtfi}done
三、通过expect进行交互
#!/bin/bash
#创建一个IP地址文件
ip.txt
#使用for循环ping测试主机是否在线
for i in {3..254}
do{ip192.168.151.$iping -c1 -W1 $ip /dev/nullif [ $? -eq 0 ]thenecho $ip ip.txt/usr/bin/expect -EOF
set timeout 10
spawn ssh-copy-id $ip
expect{
yes/no{ send yes\r;exp_continue }
password:{ send 666666\r }
}
expect eof
EOFfi}
done
wait
echo 公钥推送成功。
三、优化脚本
#!/bin/bash
#检测expect是否安装检测公钥是否创建
rpm -q expect /dev/null
if [ $? -ne 0 ]
then
yum install -y expect.x86_64 tcl tclx tcl-devl
fiif [ ! -f /root/.ssh/id_rsa ]
thenssh-keygen -P -f ~/.ssh/id_rsa
fi
#使用for循环ping测试主机是否在线之前插入安装和装备公钥。#创建一个IP地址文件
ip.txt
#使用for循环ping测试主机是否在线
for i in {3..254}
do{ip192.168.151.$iping -c1 -W1 $ip /dev/nullif [ $? -eq 0 ]thenecho $ip ip.txt/usr/bin/expect -EOF
set timeout 10
spawn ssh-copy-id $ip
expect{
yes/no{ send yes\r;exp_continue }
password:{ send 666666\r }
}
expect eof
EOFfi}
done
wait
echo 公钥推送成功。
四、脚本测试
[rootlocalhost ~]# bash exp2.sh #脚本执行
spawn ssh-copy-id 192.168.151.158
spawn ssh-copy-id 192.168.151.156
spawn ssh-copy-id 192.168.151.157
......
Number of key(s) added: 1Now try logging into the machine, with: ssh 192.168.151.158
and check to make sure that only the key(s) you wanted were added.公钥推送成功。[rootlocalhost ~]# ssh root192.168.151.156 #脚本测试
