shell批量多台服务器数据copy-优快云博客

本文介绍了一套用于批量管理服务器的Shell脚本集合，包括免密登录设置、文件同步、命令执行等功能，适用于运维人员进行多台服务器的统一管理。

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
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
95:cf:19:a5:ff:d0:bc:80:f5:de:5a:4c:b5:63:ae:c6 root@192_168_77_189
The key's randomart image is:
+--[ RSA 2048]----+

|          o o. .|

[root@192_168_77_189 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.77.190
root@192.168.77.190's password:
Now try logging into the machine, with "ssh '192.168.77.190'", and check in:

.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

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"
        ;;
