1. 停止docker服务
systemctl stop docker  
#或者
service docker stop
  1. 保存 iptables
iptables-save >  /etc/sysconfig/iptables

防火墙的配置文件/etc/sysconfig/iptables前后文件如下

保存之前文件内容:

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10001 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10002 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10003 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

保存之后的文件内容:
