生产环境:centos5.6    x86_64    expect-5.43.0-5.1

基础资源统计脚本:

 

cat monitor_servers.sh

#!/bin/sh
cat <<EOF

# iplist.txt file is needs to be monitor servers list
# monitor.exp file need four argument,example:
# expect xx.exp local_transfer_file remote_server_ip remote_cmd remote_server_passwd

echo "start remote_host to exec expect monitor script,please input remote_host passwd:"

read passwd
for host in `cat /tmp/iplist.txt`
do
 expect /root/monitor-script/monitor.exp $host "$1" $passwd >>/tmp/monitor.log 2>&1
  if [ $? -eq 0 ];then
    echo "$host run ok"
  else
    echo "$host run false"
 fi
done

 

cat monitor.exp

#!/usr/bin/expect -f
#check command line argument usage whether right
if { $argc!=3 } {
send_user "argemunt error:this script usage:expect script.filename  remote_ip exec_command remote_passwd\n"
exit
}

#define variable,get argument from expect script command line
set ip [lindex $argv 0]
set comd [lindex $argv 1]
set passwd [lindex $argv 2]

#start spawn a progress transfer file,timeout 60 exit...
spawn ssh root@$ip $comd
set timeout 60
expect {
  -timeout 20
#  "yes/no" { send "yes\r";exp_continue } 　若非第一次登录不会返回此交互结果,可
注释先
  "*password:" { exp_send "$passwd\r" }
  timeout { puts "expect connect timeout";return }
}
expect eof

exit -onexit {
send_user "$ip interaction has been completed-----------------------------\r"

 

执行过程:
# sh monitor_servers.sh "df -h;free -m"

start remote_host to exec expect monitor script,please input remote_host passwd:
123456
192.168.7.2 run ok
192.168.7.3 run ok
192.168.7.4 run ok
.....

结果可查看/tmp/monitor.log
