shell批量多台服务器数据copy

实验服务器两台:192.168.77.189
192.168.77.190
服务器免密钥登录设置：[root@192_168_77_189 ~]# ssh-keygen

Now try logging into the machine, with "ssh '192.168.77.190'", and check in: .ssh/authorized_keysto make sure we haven't added extra keys that you weren't expecting.[root@192_168_77_189 ~]# ssh 192.168.77.190

copy脚本

#!/bin/bash
#write by lixi
#time by 2015-7-7
#run by sh auto.shell.sh /root /mnt
if    [ ! -f ip.txt ] ; then
echo -e "\033[32mplease create ip.txt files...\033[0m"
cat << EOF
192.168.149.128
192.168.149.129
EOF
exit
fi
if
[ -z "$1" ] ; then
echo -e "\033[32mUsage $0 command,example{src_file|src_dir Des_dir\033[0m}"
exit
fi
count=`cat ip.txt | wc -l`
rm -rf ip.txt.swp
i=0
while  ((i<$count))
do
i=`expr $i + 1`
sed "${i}s/^/&${i} /g"  ip.txt >> ip.txt.swp
IP=`awk -v I="$i" '{if(I==$1)print $2}' ip.txt.swp`
scp -r $1 root@${IP}:$2
#rsync -ap --delete $1 root@${IP}:$2
done

以上脚本用rsync也可以，，，rsync同步两个文件一样，，，例如sh auto.shell.sh /opt/ /opt/保持两个服务器之间这个目录文件一样4.批量远程服务器执行命令

#!/bin/bash
# Auto run server commend
# by lx 2015-7-7
if [ ! -f ip.txt ]; then
echo -e "\033[32mplease create ip.txt files...\033[0m"
cat << EOF
192.168.149.128
192.168.149.129
EOF
exit
fi
if
[ -z "$*" ] ; then
echo -e "\033[32mUsage: $0 Commend,Example{rm /tmp/text.txt|mkdir /tmp/text2}\033[0m"
exit
fi
count=`cat ip.txt | wc -l`
rm -rf ip.txt.swp
i=0
while ((i<$count))
do
i=`expr $i + 1`
sed "${i}s/^/&${i} /g" ip.txt >>ip.txt.swp
IP=`awk -v I="$i" '{if(I==$1)print $2}' ip.txt.swp`
ssh -q -l root $IP "$*; echo -e '-----------------------\nthe $IP Exec command:
$* success !';sleep 2"
done

root@192_168_77_189 ~]# sh auto_ssh.sh mkdir /tmp/text2
-----------------------
the 192.168.77.190 Exec command:
mkdir /tmp/text2 success !
-----------------------
the 192.168.77.189 Exec command:
mkdir /tmp/text2 success !

5.服务器之前文件同步：
#!/bin/bash
#by lixi 2015.7.7
#run by sh auto_rsync.sh flush
flush()
{
if
[ ! -f rsync.list ]; then
echo -e "\033[32mplease create rsync.list file...\033[0m"
cat << EOF
192.168.149.128 src_dir des_dir
192.168.149.129 src_dir des_dir
EOF
exit
fi
rm -rf rsync.list.swp ; cat rsync.list | grep -v "#" >rsync.list.swp
COUNT=`cat rsync.list.swp|wc -l`
NUM=0
while ((${NUM} < $COUNT))
do
NUM=`expr $NUM + 1`
Line=`sed -n "${NUM}p" rsync.list.swp`
SRC=`echo $Line |awk '{print $2}'`
DES=`echo $Line |awk '{print $3}'`
IP=`echo $Line |awk '{print $1}'`
rsync -ap --delete ${SRC}/ root@${IP}:${DES}/
done
}
restart()
{
rm -rf restart.list.swp ; cat restart.list | grep -v "#" >> restart.list.swp
COUNT=`cat restart.list.swp|wc -l`
NUM=0
while ((${NUM} < $COUNT))
do
NUM=`expr $NUM + 1`
Line=`sed -n "${NUM}p" restart.list.swp`
Command=`echo $Line |awk '{print $2}'`
IP=`echo $Line |awk '{print $1}'`
ssh -l root $IP "sh $Command; echo -e '----------------\nthe $IP Exec Commadn : sh $Command success !'"
done
}
case $1 in
flush )
flush
;;
restart )
restart
;;
* )
echo -e "\033[32mUsage: $0 command,example {flush|restart}\033[0m"
;;
esac
