shell项目-分发系统-expect

安装expect

[root@lynn-04 ~]# yum install -y expect

用脚本登陆远程机器 编写脚本1.expect 内容如下：

[root@lynn-04 expect]# vim 1.expect
#!/usr/bin/expect
set host "192.168.130.128"     #定义变量
set passwd "6811327"             #定义变量
spawn ssh root@$host
expect {
"yes/no" {send "yes\r"; exp_continue }        #当提示语句出现yes/no 输入yes然后继续
"password:" {send "$passwd\r" }                #当提示语句出现password 输入密码
}
interact

执行结果

[root@lynn-04 expect]# chmod a+x 1.expect ; ./1.expect
spawn ssh root@192.168.130.128
root@192.168.130.128's password:

用脚本登陆远程机器执行命令后退出 编写脚本2.expect 内容如下：

[root@lynn-04 expect]# vim 2.expect

#!/usr/bin/expect
set user "root"
set passwd "6811327"
spawn ssh $user@192.168.130.128

expect {
"yes/no" { send "yes\r"; exp_continue}
"password:" { send "$passwd\r" }
}
expect "]*"
send "touch /tmp/12.txt\r"
expect "]*"
send "echo 1212 > /tmp/12.txt\r"
expect "]*"
send "ls -l /tmp/12.txt\r"
expect "]*"
send "cat /tmp/12.txt\r"
expect "]*"
send "exit\r"

执行结果

[root@lynn-04 expect]# chmod a+x 2.expect ; ./2.expect
spawn ssh root@192.168.130.128
root@192.168.130.128's password:

[root@lynn-06 ~]# touch /tmp/12.txt
[root@lynn-06 ~]# echo 1212 > /tmp/12.txt
[root@lynn-06 ~]# ls -l /tmp/12.txt

[root@lynn-06 ~]# cat /tmp/12.txt
1212
[root@lynn-06 ~]# [root@lynn-04 expect]# 

脚本传递参数 编写脚本3.expect 内容如下：

[root@lynn-04 expect]# vim 3.expect

#!/usr/bin/expect

set user [lindex $argv 0]
set host [lindex $argv 1]
set passwd "6811327"
set cm [lindex $argv 2]
spawn ssh $user@$host

expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]*"
send "$cm\r"
expect "]*"
send "exit\r"

执行结果

[root@lynn-04 expect]# chmod a+x 3.expect ; ./3.expect root 192.168.130.128 ls

设置超时 在执行的命令下面加上一行 set timeout -1 #永不超时 set timeout 1 #1秒超时 set timeout 5 #5秒超时 例如： expect "]*" send "vmstat 1" #这个命令会一直执行 set timeout -1

expect "]*" send "vmstat 1" #这个命令会5秒后自动停止 set timeout 5

自动同步文件 编写脚本 内容如下：

[root@lynn-04 expect]# vim 4.expect

#!/usr/bin/expect
set passwd "6811327"
spawn rsync -av root@192.168.130.128:/tmp/12.txt /tmp/

expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}

expect eof

执行结果

[root@lynn-04 expect]# chmod a+x 4.expect ; ./4.expect
spawn rsync -av root@192.168.130.128:/tmp/12.txt /tmp/
root@192.168.130.128's password:
