說明：系統環境CentOS release 6.5 (Final) 2.6.32-431.el6.x86_64

1.添加分發用戶

useradd oldgirl

echo 123456|passwd stdin --oldgirl

2.利用rsync用戶名進行sudo提取cp權限並用-c檢查語法

echo ‘oldgirl ALL=(ALL) NOPASSWD:/usr/bin/rsync‘ >>/etc/sudoers

visudo -c

grep oldgirl /etc/sudoers

3.產生秘鑰對

ssh-keygen -t dsa/rsa

一直回車

ll .ssh/ 查看

4.向客戶端發送公鑰

ssh-copy-id -i .ssh/id_dsa.pub [email protected]

ssh-copy-id -i .ssh/id_dsa.pub [email protected]

ssh-copy-id -i .ssh/id_dsa.pub [email protected]

5.新建分發腳本vim fenfa_good.sh

#!/bin/sh

. /etc/init.d/functions

if [ $# -ne 2 ]

then

echo "USAGE:$0 localfile remotedir"

exit 1

fi

for n in 3 4 5

do

echo " ===============172.16.1.$n============"

scp -p22 -r $1 [email protected]$n:~ &>/dev/null &&\

ssh -t [email protected]$n sudo rsync $1 $2 &>/dev/null

if [ $? -eq 0 ]

then

action "fenfa $1 ok" /bin/true

else

action "fenfa $1 ok" /bin/false

fi

done
