ssh批量传输秘钥

方法一、sshpass

安装

1
yum install sshpass -y

免密

2
3
for i in {1..10};do 
sshpass -p 'Pass-1234' ssh-copy-id -f -o StrictHostKeyChecking=no root@172.20.20.$i
done

我知道你记不住StrictHostKeyChecking，so

2
[root@linux2 ~]# grep Str /etc/ssh/ssh_config
#   StrictHostKeyChecking ask

方法二、expect

安装

yum install expect -y

免密

for i in {1..10};do expect << EOF
spawn ssh-copy-id root@172.20.20.$i
expect "yes/no" {send "yes\r"}
expect "password" {send "Pass-1234\r"}
expect eof
EOF
done
