分两步：
1，JAVA程序是否OK
关掉iptables看是否能打开。
2，IPtables没有贴出全部，用下面的脚本执行一下。
sh name.sh
#!/bin/bash#Purpose:Initial Firewall setting on Centos
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH
## Check if user is root
(( $EUID != 0 )) && {
echo "ERROR: You must be root to run this script."
exit 1
}

export PATH
CUR_DIR="$(cd -P "$(dirname "${BASH_SOURCE[0]}")" && pwd)"

function init_fwhost(){
echo -e "\033[32mBackup iptables configuration ...backup path:/etc/sysconfig\033[0m"
service iptables start
iptables-save >/etc/sysconfig/iptables.bak.${CUR_TIME}
echo -e "\033[32mInit configuration ...\033[0m"
iptables -F
iptables -X
iptables -Z
iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT
iptables -P FORWARD DROP
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT

iptables -A INPUT -p udp --dport 53 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j ACCEPT
##add other ip list from here
iptables -A INPUT -j DROP
service iptables save
service iptables restart
chkconfig iptables on
}
#Do main
init_fwhost
