安装sshpass

sshpass: 用于非交互的ssh 密码验证

 ssh登陆不能在命令行中指定密码,也不能以shell中随处可见的,sshpass 的出现,解决了这一问题。它允许你用 -p 参数指定明文密码,然后直接登录远程服务器。 它支持密码从命令行,文件,环境变量中读取

安装sshpass

curl -O -L http://downloads.sourceforge.net/project/sshpass/sshpass/1.06/sshpass-1.06.tar.gz && tar xvzf sshpass-1.06.tar.gz && cd sshpass-1.06 && ./configure && make && sudo make install

安装后执行sshpass -V查看版本

sshpass -V

Using "assword" as the default password prompt indicator.

sshpass -h查看帮助

Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
-f filename Take password to use from file
-d number Use number as file descriptor for getting password
-p password Provide password as argument (security unwise)
-e Password is passed as env-var "SSHPASS"
With no parameters - password will be taken from stdin

-P prompt Which string should sshpass search for to detect a password prompt
-v Be verbose about what you're doing
-h Show help (this screen)
-V Print version information
At most one of -f, -d, -p or -e should be used

    sshpass 参数 SSH命令(ssh,sftp,scp等)。
    参数:
        -p  password    //将参数password作为密码。
        -f   passwordfile //提取文件passwordfile的第一行作为密码。

    -d   使用数字作为文件描述符来获取密码
        -e  //将环境变量SSHPASS作为密码。

另外,对于ssh的第一次登陆,会提示:“Are you sure you want to continue connecting (yes/no)”,这时用sshpass会不好使,可以在ssh命令后面加上 -o StrictHostKeyChecking=no来解决。比如说上面的命令,就可以写作ssh -p efghi scp abc@192.168.0.5:/home/xxx/test /root -o StrictHostKeyChecking=no。
