Centos shell脚本批量下发密钥实现免密登陆+面密传输

懂的都懂，直接上脚本

[root@localhost ~]# cat host.txt
10.10.220.19
10.10.220.17

InFo_date(){
    date=`date +%Y-%m-%d-%k:%M:%S`
}
InFo_Echo(){
    echo -e "33[32m${1}33[0m"
}
InFo_Echo_2(){
    echo -e "33[33mt${1}33[0m : 33[33m${2}33[0m"
}

HostFile=`cat /root/host.txt`


InFo_sshkey(){
#删除本机旧密钥文件
rm -rf /root/.ssh/id_dsa*
#生成最新密钥文件
ssh-keygen -t dsa -f /root/.ssh/id_dsa -P ""  -q 
#遍历host文件
for ip in $HostFile
do
	InFo_Echo "=======Batch the file to the host $ip=========="	
    sshpass -p 'perfma@1098' scp ~/.ssh/id_dsa.pub  root@"$ip":/root/.ssh/authorized_keys
    if [ $? -eq 0 ];then 
    InFo_Echo_2 IP:"$ip" "SSHkey Push Succeeded" else InFo_Echo_2 IP:"$ip" "SSHkey Push Failed"
    fi
	InFo_Echo "##########################END##########################n"
done
}
InFo_sshkey

接下来传文件和登陆服务器都不需要密码了
