- 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：
[[email protected]_168_77_189 ~]# ssh-keygen

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

# Auto run server commend
# by lx 2015-7-7

exit

if
[ -z "$*" ] ; then
echo -e "\033[32mUsage: $0 Commend,Example{rm /tmp/text.txt|mkdir /tmp/text2}\033[0m"
exit

count=`cat ip.txt | wc -l`
rm -rf ip.txt.swp
i=0
while ((i<$count))
do

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:

done
