nexus安装和防火墙配置

一、防火墙安装

#!/bin/bash

#测试恢复原有防火墙配置
yum remove iptables-services -y
systemctl start firewalld

#停止并关闭开机自启原有防火墙
systemctl stop firewalld
systemctl disable firewalld
#安装iptables防火墙
yum install iptables-services -y

#启动iptables
service iptables start 
#开启8080,8081端口
iptables -I INPUT -ptcp --dport 8081 -j ACCEPT

#保存配置到iptables的配置文件
service iptables save
#设置开机自启
systemctl enable iptables.service

echo "iptables is over !"

二、防火墙端口配置

#!/bin/bash
service iptables status
if [ $? -eq 0 ];
then
echo "已安装了iptables,open port $1"
iptables -A INPUT -p tcp --dport $1 -j ACCEPT
service iptables save
systemctl restart iptables
else
#安装iptables
yum install -y iptables
#安装iptables-services
yum install -y iptables-services
#禁用/停止自带的firewalld服务
