运用sshpass及脚本实现批量建立信任关系

1、http://sourceforge.net/projects/sshpass/

2、

#cd sshpass-1.05/

3.

#./configure && make && make install

4.

#sshpass -p aixocm ssh 192.168.199.129直接登录

5.

#sshpass -p aixocm scp sshpass-1.05.tar.gz  192.168.199.129:/lianxi

6、脚本实现批量建立单向信任

#vim  /shell/sshpass.sh

IP=`cat ip_list.txt`

error_check()
        echo  "$1 error" >error.log
        exit
fi
}
create()
{
IP=`cat ip_list.txt`
PASS=`cat passwd.txt`
#####error check##########
error_check()
{
if ((   $? != 0 ));then
        echo  "$1 error" >error.log
        exit
fi
}
create()
{
for i in $IP
do
sshpass  -p $PASS ssh  $i useradd liu
error_check Adduser
sshpass  -p $PASS ssh  $i mkdir /home/liu/.ssh
error_check directory_create
sshpass  -p $PASS ssh  $i chmod 700 /home/liu/.ssh
error_check permissions
sshpass  -p $PASS ssh  $i chown liu:liu /home/liu/.ssh
error_check owner
sshpass  -p $PASS scp /home/liu/.ssh/authorized_keys  $i:/home/liu/.ssh
error_check scp_use

sshpass  -p $PASS ssh  $i chmod 600 /home/liu/.ssh/authorized_keys
error_check chown600
sshpass  -p $PASS ssh  $i chown liu:liu /home/liu/.ssh/authorized_keys
error_check chownliu
echo  "与$i的单向关系已经建立"
done
}
create
