CentOS7默认的防火墙不是iptables,而是firewall.
由于习惯了用iptables作为防火墙,所以在安装好centos7系统后,会将默认的firewall关闭,并另安装iptables进行防火墙规则设定

下面介绍centos7关闭firewall安装iptables,并且开启80端口、3306端口的操作记录:

1、关闭firewall:

[root@localhost ~]# systemctl stop firewalld.service            //停止firewall[root@localhost ~]# systemctl disable firewalld.service        //禁止firewall开机启动
2、安装iptables防火墙
[root@localhost ~]# yum install iptables-services            //安装[root@localhost ~]# vim /etc/sysconfig/iptables              //编辑防火墙配置文件# Firewall configuration written by system-config-firewall# Manual customization of this file is not recommended.*filter:INPUT ACCEPT [0:0]:FORWARD ACCEPT [0:0]:OUTPUT ACCEPT [0:0]-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT-A INPUT -p icmp -j ACCEPT-A INPUT -i lo -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT-A INPUT -j REJECT --reject-with icmp-host-prohibited-A FORWARD -j REJECT --reject-with icmp-host-prohibitedCOMMIT [root@localhost ~]# systemctl restart iptables.service                  //最后重启防火墙使配置生效[root@localhost ~]# systemctl enable iptables.service                  //设置防火墙开机启动 [root@localhost ~]# iptables -L                 //查看防火墙规则,默认的是-t filter,如果是nat表查看,即iptables -t nat -L
3、关闭SELINUX

[root@localhost ~]# vim /etc/selinux/config#SELINUX=enforcing           //注释掉#SELINUXTYPE=targeted           //注释掉SELINUX=disabled              //增加  [root@localhost ~]# setenforce 0       //使配置立即生效
