• 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：
  [iyunv@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:

  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.

#!/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

#!/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

        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"
