我是靠谱客的博主活泼钢笔，最近开发中收集的这篇文章主要介绍expect自动检测并重启另外一台服务器上的程序代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

[s005 you] # cat haproxy_expect

复制代码代码如下:

#!/usr/bin/expect
set ssh_user "fivetrees"
set password "123456"
spawn ssh -i /root/.ssh/$ssh_user Server004.xd.com
expect_before "no)?" {
send "yes\r" }
sleep 0.5
expect "Enter passphrase for key*"
send "$password\r"
expect "*#"
send "/tmp/haproxy.sh\r"
expect "*#"
send "echo\r"
exit

[s004 him] # cat haproxy.sh

复制代码代码如下:

#!/bin/bash
Thread=`ps -ef | grep haproxy | grep -v haproxy.sh | grep -v grep`
if [ -z "$Thread" ]
then
        /tmp/haproxy_expect
fi

[s004 him] # cat haproxy_expect

复制代码代码如下:

#!/usr/bin/expect
set ssh_user "fivetrees"
set password "123456"
spawn ssh -i /root/.ssh/$ssh_user Server005.xd.com
expect_before "no)?" {
send "yes\r" }
sleep 0.5
expect "Enter passphrase for key*"
send "$password\r"
expect "*#"
send "/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg\r"
expect "*#"
send "echo\r"
exit
