自动安装puppet脚本

vm1为master  hostname为vm1.example.com

vm2 vm3 vm4为client,hostname为vm2|vm3|vm4.example.com

脚本如下：

#!/bin/bash 
PROG_NAME=$0 
vm=$1 
 
usage() { 
    echo "Usage: $PROG_NAME {vm1|vm2|vm3|vm4|reca}" 
    exit 1; 
} 
 
if [ $# -ne 1 ]; then 
    usage 
fi 
 
prepare() 
{ 
echo "alias vivim=vi">> ~/.bash_profile 
service iptables stop 
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 
/usr/sbin/ntpdate time.nist.gov 
echo "*/5 * * * * /usr/sbin/ntpdate time.nist.gov" > /var/spool/cron/root 
chmod 600 /var/spool/cron/root 
} 
 
install_master() 
{
