臨時擼一段，備份下 說不定啥時候用一下，沒有做多線程什么的，效率會低很多。偶爾用一下算是可以接受吧，畢竟一般批量的操作應(yīng)該都有中控機(jī)進(jìn)行下key。

首先準(zhǔn)備一份服務(wù)器信息文件

localhost:~ dada$ cat hostinfo
1.1.1.1 root xxxxx
2.2.2.2 root xxxxx
3.3.3.3 root xxxxx
4.4.4.4 root xxxxx

復(fù)制腳本吧

#!/bin/bash
hosts=$1
command=$2

if [ ! -e ${hosts} ]
then
   echo "服務(wù)器列表文件不存在!"
   exit 1
fi

if [ ! -n "${command}" ]
then
   echo "無命令輸入!"
   exit 1
fi

while read ipInfo
do
   ipAddr=`echo ${ipInfo}|awk '{print $1}'`
   userName=`echo ${ipInfo}|awk '{print $2}'`
   userPass=`echo ${ipInfo}|awk '{print $3}'`
   commandInfo=`sshpass -p "${userPass}"  ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ${userName}@${ipAddr} 2>/dev/null -n "${command}"`

   if [ "x$?" = "x0" ]
   then
       echo "${ipAddr} [SUCCESS]"
       echo "${commandInfo}"
   else
       echo "${ipAddr} [FAIL]"
   fi
done<${hosts}

下面是執(zhí)行

服務(wù)器無法連接
localhost:~ dada$ ./pass_ssh.sh ./hostinfo "free -g"
1.1.1.1 [FAIL]

服務(wù)器可以連接
localhost:~ dada$ ./pass_ssh.sh ./hostinfo "free -g"
1.1.1.1 [SUCCESS]
