一、简述

运维工作中远程登录执行命令的脚本很常用，下面分享一下我常用的脚本

二、脚本内容

#!/bin/bash

SCRIPT_NAME=`basename $0`

CURRENT_DIR=$(cd "$(dirname "$0")";pwd)

execute_ssh_cmd()

{

local host_ip=$1

local user_name=$2

local user_password=$3

local cmd="$4"

local log_file=${CURRENT_DIR}/execute_ssh_cmd.log

# 如果密码中包含$符号，需要转义以下

user_password=`echo ${user_password} | sed 's/\\$/\\\\$/g'`

/usr/bin/expect < ${log_file}

set timeout -1

spawn ssh ${user_name}@${host_ip}

expect {

"(yes/no)?"

{

send "yes\n"

expect "*assword:" { send "${user_password}\n"}

}

"*assword:"

{

send "${user_password}\n"

}

sleep 1

send "${cmd}\n"

send "exit\n"

expect eof

EOF

cat ${log_file} | grep -iE "Permission denied|failed" >/dev/null

if [ $? -eq 0 ];then

echo "Script execute failed!"

return 1

fi

return 0

}

execute_ssh_cmd "$@"

[root@localhost opt]# cat execute_ssh_cmd.log

spawn ssh root@192.168.233.134
