systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动

setenforce 0
永久关闭：
vim /etc/selinux/config打开selinux配置文件

swapoff -a && sed -ri ‘s/.*swap.*/#&/‘ /etc/fstab

在/etc/sysctl.conf中添加以下配置：

net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1 
net.ipv4.ip_forward=1

如果报出参数不存在，则执行modprobe br_netfilter即可

并执行sysctl -p
