使用sshpass方式实现ssh自动登录

1：sshpass下载地址（用yum安装不了）      https://sourceforge.net/projects/sshpass/files/

or

wget http://sourceforge.net/projects/sshpass/files/latest/download -O sshpass.tar.gz

 2：下载后，解压，安装

tar -zxvf sshpass-1.06.tar.gz
cd sshpass-1.06
./configure
make
make install

3：使用命令      sshpass -p 123456 ssh root@10.0.0.37 -o StrictHostKeyChecking=no        后面这个是“Are you sure you want to continue connecting (yes/no)”使得这个自动接受，若不加，则成功不了 4：脚本

    #!/bin/bash
    #Use sshpass way Achieve ssh auto login
    set-x
    password=123456
    user=root
    ip=10.0.0.37
    sshpass -p $password ssh $user@$ip -o StrictHostKeyChecking=no
