测试环境分发2台主机

环境准备

编写相应脚本

`生成密码`
[root@ansibel ssh]# ssh-keygen 
`把对应密码放入到txt文件`
[root@ansibel ssh]# cat ip_pwd.txt 
192.168.139.36 root
192.168.139.30 root
`脚本`
[root@ansibel ssh]# cat ssh_add.sh 
#!/bin/bash
while read ip passwd ;do
  sshpass -p$passwd ssh-copy-id -i /root/.ssh/id_rsa.pub $ip -o StrictHostKeyChecking=no &>/dev/null 
   if [ $? -eq 0 ]; then
     echo "主机${ip}分发成功！！"
   else
     echo "主机${ip}分发失败@@@"
   fi
done < ip_pwd.txt
​
`运行脚本`
[root@ansibel ssh]# bash ssh_add.sh 
主机192.168.139.36分发成功！！
主机192.168.139.30分发成功！！
`验证`
[root@ansibel ssh]# ssh 192.168.139.36
Last login: Fri Nov 17 11:28:12 2023 from 192.168.139.71
[root@web-server2 ~]# exit
logout
Connection to 192.168.139.36 closed.
[root@ansibel ssh]# ssh 192.168.139.30
Last login: Fri Nov 17 11:49:21 2023 from 192.168.139.1
[root@web-server1 ~]# 

批量分发100台主机

生成IP和密码

[root@ansibel ssh]# cat ip_passwd.sh 
#!/bin/bash
#批量生成ip 和密码
​
for i in {1..2}; do
  for j in {1..50};do
    IP="192.168.${i}.${j}"
    PASSWD=`echo $RANDOM | md5sum |cut -c -12`
    echo $IP $PASSWD >> ip_pwd.txt
  done
done
​
`运行脚本生成100个IP和对应密码`
[root@ansibel ssh]# bash ip_passwd.sh
[root@ansibel ssh]# cat ip_pwd.txt | wc -l
100
[root@ansibel ssh]# tail  ip_pwd.txt 
192.168.2.41 10ae913661c9

192.168.2.49 217854aa0ff4
192.168.2.50 92d7d1b5e644

编写ssh分发脚本

[root@ansibel ssh]# cat ssh_add.sh
#!/bin/bash
while read ip passwd ;do
  sshpass -p$passwd ssh-copy-id -i /root/.ssh/id_rsa.pub $ip -o StrictHostKeyChecking=no &>/dev/null 
 if [ $? -eq 0 ] then
   echo "主机${ip}分发成功！！"
 else
   echo "主机${ip}分发失败@@@"
 fi
done < ip_pwd.txt
​
`运行脚本`
[root@ansibel ssh]# bash -x ssh_add.sh 
+ read ip passwd
+ sshpass -p0c8f7e90b9d6 ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.1.1 -o StrictHostKeyChecking=no
+ '[' 1 -eq 0 ']'
+ echo 主机192.168.1.1分发失败@@@
主机192.168.1.1分发失败@@@
+ read ip passwd
+ sshpass -pacaa2db0f5be ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.1.2 -o StrictHostKeyChecking=no
+ '[' 1 -eq 0 ']'
+ echo 主机192.168.1.2分发失败@@@
主机192.168.1.2分发失败@@@
#脚本效果没有问题只是因为我们的ip是随机生成的所以分发失败
