#注意：服务器需要安装expect

一、源码包安装要安装expect,linux expect的安装

1.安装相应的包

   yum install -y tcl tclx tcl-devel

2.下载expect-5.43.tar.gz包（我这里用的这个包，大家也可以用别的）

根据参数，运行./configure
./configure --with-tcl=/usr/lib --with-tclinclude=/usr/include/tcl-private/generic
3.make && make install  安装完毕


二、yum 安装

yum install -y expect


问题处理：

./auto_scpfile.sh: line 2: spawn: command not found

couldn't read file "password:": no such file or directory

./auto_scpfile.sh: line 8: send: command not found

./auto_scpfile.sh: line 10: interact: command not found

这样的话，脚本要指定expect:  #!/usr/bin/expect
