1、使用expect

#!/usr/bin/expect

set host "192.168.1.10"

set username "nginx"

set password "nginx" 

spawn rsync -av ~/test/  ${username}@${host}:~/test/

expect {

"(yes/no)?" { send "yes\r"; exp_continue}

"password:" { send "$password\r" }

}

expect eof

spawn scp -P "${port}"  "${src}"  ${username}@${host}:"${dst}"

expect {

"(yes/no)?" { send "yes\r"; exp_continue}

"password:" { send "$password\r" }

}

expect "100%"

expect eof

expect -c 直接在命令行中执行脚本中的命令

expect -c "

    set timeout 30

    spawn rsync -av ~/test/  ${username}@${host}:~/test/

    expect {

    "(yes/no)?" { send "yes\r"; exp_continue} 

}

expect eof

"

2、使用加密传输

    1)生成公钥

       ssh-keygen -t rsa -C "nginx@192.168.1.19" -f ~/AUTH_NGINX

    2）把公钥传给192.168.1.10，

       scp AUTH_NGINX.pub nginx@192.168.1.10:~/.ssh

       cat AUTH_NGINX.pub >> authorized_keys

    3)传输文件

       rsync -av -e "ssh -i AUTH_NGINX" test/ nginx@192.168.1.10:~/test/

3、免密码登录：

#!/usr/bin/expect

set host "xxxxxx"

set port "1101"

set username "root"

set password "xxxxxx" 

spawn ssh -p ${port} ${username}@${host}

expect {

"(yes/no)?" { send "yes\r"; exp_continue}

"password:" { send "$password\r" }

}

#expect eof

expect "*#"

interact

expect传参数

#!/usr/bin/expect

#set host "${hostInterIp}"

#set port "${SSH_PORT}"

#set username "${SSH_USER}"

#set password "${SSH_PWD}" 

set date [exec date "+%Y-%m-%d"]

                                                                                                                                                                                                                                                                              

set host [lindex $argv 0 ]      

set username [lindex $argv 1]

set password [lindex $argv 2 ]  

set port [lindex $argv 3 ]

 

spawn ssh -p ${port} ${username}@${host}      

expect {

"(yes/no)?" { send "yes\r"; exp_continue}     

"password:" { send "$password\r" }            

}

#expect eof

expect "*#"

interact

4、用私钥去连接：

eval `ssh-agent`

ssh-add ~/.ssh/los 私钥
