linux 批量拷贝数据脚本

浏览数：46 / 时间：2015年06月20日

最近想弄个批量传输拷贝部署远程服务器脚本

思路：1.与远程客户端建立等效性

2.拷贝数据、或者执行远程服务器命令

自动化等效性脚本如下：前提是安装expect这个包

================================================================

服务端生成自动生成rsa key

#!/usr/bin/expect
rm -rf root/.ssh/known_hosts
expect -c "
spawn ssh-keygen -t rsa
expect {
\"*id_rsa*\" {send \r;exp_continue}
\"*passphrase*\" {send \r;exp_continue}
\"*again*\" {send \r;exp_continue}
}

===============================================================

拷贝生成的key到远程服务器上

for p in $(cat /script/ip.txt)
do
ip=$(echo "$p"|cut -f1 -d":")
password=$(echo "$p"|cut -f2 -d":")
expect -c "
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@$ip
        expect {
                \"*yes/no*\" {send \"yes\r\"; exp_continue}
                \"*password*\" {send \"$password\r\"; exp_continue}
                \"*Password*\" {send \"$password\r\";}
        }
"
done

其中ip.txt内容格式为如下：

192.168.1.56:123456

===============================================================

执行服务端到客户端推送命令

for h in $(cat /script/ip.txt|cut -f1 -d":")
do
ssh root@$h "ls $dire"
dire="/tmp/test"
if [ $? -eq 0 ];
then
ssh root@$h rm -rf "$dire"
set timeout 300
ssh root@$h mkdir -p /tmp/test
fi
ssh root@$h touch lgl.txt
scp /root/CentOS-5.3-x86_64-bin-DVD.iso [email protected]:/home
set timeout 300
done

===============================================================

最后脚本如下：

[root@lgl script]# cat ssh.sh
#!/usr/bin/expect
rm -rf root/.ssh/known_hosts
expect -c "
spawn ssh-keygen -t rsa
expect {
\"*id_rsa*\" {send \r;exp_continue}
\"*passphrase*\" {send \r;exp_continue}
\"*again*\" {send \r;exp_continue}
}
"
for p in $(cat /script/ip.txt)
do
ip=$(echo "$p"|cut -f1 -d":")
password=$(echo "$p"|cut -f2 -d":")
expect -c "
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@$ip
        expect {
                \"*yes/no*\" {send \"yes\r\"; exp_continue}
                \"*password*\" {send \"$password\r\"; exp_continue}
                \"*Password*\" {send \"$password\r\";}
        }
"
done
for h in $(cat /script/ip.txt|cut -f1 -d":")
do
ssh root@$h "ls $dire"
dire="/tmp/test"
if [ $? -eq 0 ];
then
ssh root@$h rm -rf "$dire"
set timeout 300
ssh root@$h mkdir -p /tmp/test
fi
ssh root@$h touch lgl.txt
scp /root/CentOS-5.3-x86_64-bin-DVD.iso [email protected]:/home
set timeout 300
done
