1.安裝

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

安裝expect命令 兩種方式
yum安裝

yum -y install expect

手動安裝

expect以及tcl版本

複製程式碼
#!/bin/bash
oldpath=`pwd`
tar -zxf tcl8.4.20-src.tar.gz
#3.安裝配置
cd tcl8.4.20/unix
./configure --prefix=/usr/tcl --enable-shared
make
make install
#注意：
#1、安裝完畢以後，進入tcl原始碼的根目錄，把子目錄unix下面的tclUnixPort.h copy到子錄generic中。
cp ./tclUnixPort.h ../generic/

#（二）expect 安裝 (需Tcl的庫)

#2.解壓縮原始碼包
cd $oldpath
tar xzf expect5.45.tar.gz
#3.安裝配置
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
複製程式碼

testcase

複製程式碼
#!/bin/bash
#create hadoop user
user1=$1
useradd $user1

expect -c "
set timeout -1;
spawn passwd $user1;
expect {
*password:* {send -- hadoop\r;exp_continue;}
eof {exit 0;}
}"
# 更改使用者組為root
usermod -g root $user1
#test comand
# id $user1

2.使用

以拉取遠端伺服器mysql備份為例 總共2個檔案，備份檔案自己建立

vimysqlbackup.sh

#!/bin/sh

source /etc/profile

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

mysqlfile=********專案名_${DATE}*.sql.gz

password=********

#傳遞密碼和檔名到mysql檔案

./mysql $password $mysqlfile

echo "pull mysqlfile end"

vimysql

#!/usr/bin/expect

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

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

expect {
"密碼："
{
send "$password\n"
}
"password"
{
send "$password\n"
}
"yes/no"
{
sleep 5
send_user "send yes"
send "yes\n"
}
eof
{
sleep 5
send_user "eof\n"
}
}
set timeout 3000
send "exit\r"
expect eof
