Linux之CentOS 7替换Firewalld为iptables和禁用ipv6

禁用IPV6

echo -e 'net.ipv6.conf.all.disable_ipv6 = 1\nnet.ipv6.conf.default.disable_ipv6 = 1' >> /etc/sysctl.conf && sysctl -p

替换Firewalld为iptables

systemctl mask firewalld
systemctl stop firewalld
yum -y install iptables-devel iptables-services iptables
systemctl enable iptables
systemctl start iptables
