centos7 自动交互expect 安装使用

1.安装

https://www.cnblogs.com/rocky-AGE-24/p/7256800.html

安装expect命令 两种方式
yum安装

yum -y install expect

手动安装

expect以及tcl版本

复制代码
#!/bin/bash
oldpath=`pwd`
tar -zxf tcl8.4.20-src.tar.gz
#3.安装配置
cd tcl8.4.20/unix
./configure --prefix=/usr/tcl --enable-shared
make
make install
#注意：
#1、安装完毕以后，进入tcl源代码的根目录，把子目录unix下面的tclUnixPort.h copy到子录generic中。
cp ./tclUnixPort.h ../generic/

#（二）expect 安装 (需Tcl的库)

#2.解压缩源码包
cd $oldpath
tar xzf expect5.45.tar.gz
#3.安装配置
cd expect5.45
./configure --prefix=/usr/expect --with-tcl=/usr/tcl/lib --with-tclinclude=../tcl8.4.20/generic
make
make install
ln -s /usr/tcl/bin/expect /usr/expect/bin/expect
ln -s /usr/tcl/bin/expect /usr/bin/expect
复制代码

testcase

复制代码
#!/bin/bash
#create hadoop user
user1=$1
useradd $user1

expect -c "
set timeout -1;
spawn passwd $user1;
expect {
*password:* {send -- hadoop ;exp_continue;}
eof {exit 0;}
}"
# 更改用户组为root
usermod -g root $user1
#test comand
# id $user1

2.使用

以拉取远程服务器mysql备份为例  总共2个文件，备份文件自己创建

vi mysqlbackup.sh 

#!/bin/sh

source /etc/profile

DATE=`date +%Y%m%d`

mysqlfile=********项目名_${DATE}*.sql.gz

password=********

#传递密码和文件名到mysql文件

./mysql $password $mysqlfile

echo "pull mysqlfile end"

vi mysql

#!/usr/bin/expect

set password [lindex $argv 0]
set mysqlfile [lindex $argv 1]

#全部拉取
#spawn scp -r root@ip:/data/mysqlbackup/${BACK_DATA}.sql.gz /home/backup/mysqlbackup
#拉取指定的文件
spawn scp -r root@ip:/data/mysqlbackup/$mysqlfile /home/backup/mysqlbackup

expect {
"密码："
{
send "$password "
}
"password"
{
send "$password "
}
"yes/no"
{
sleep 5
send_user "send yes"
send "yes "
}
eof
{
sleep 5
send_user "eof "
}
}
set timeout 3000
send "exit "
expect eof
