1：sshpass下載地址（用yum安裝不了）
or
wget http://sourceforge.net/projects/sshpass/files/latest/download -O sshpass.tar.gz
2：下載后，解壓，安裝
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
后面這個是
“Are you sure you want to continue connecting (yes/no)”使得這個自動接受，若不加，則成功不了
4：腳本
#!/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
