想了解expect自动检测并重启另外一台服务器上的程序代码的相关内容吗，在本文为您仔细讲解expect自动检测的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：expect,自动检测，下面大家一起来学习吧。
[s005 you] # cat haproxy_expect
#!/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
#!/bin/bash
Thread=`ps -ef | grep haproxy | grep -v haproxy.sh | grep -v grep`
if [ -z "$Thread" ]
then
/tmp/haproxy_expect
fi
[s004 him] # cat haproxy_expect
#!/usr/bin/expect
set ssh_user "fivetrees"
set password "123456"
spawn ssh -i /root/.ssh/$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
