使用sshpass实现ssh、scp等免密登录
ssh 登陆不能在命令行中指定密码,sshpass 的出现则解决了这一问题。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:yum install -y sshpass
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
如:sshpass -p 'root' scp /opt/file.txt root@192.168.126.135:/home
