Ubuntu配置防火墙，并且开机iptables自启动规则;适用于CentOS1、登录root账号# 切换到root账号super@super:~$ sudo passwd root # 设置root密码super@super:~$ su - root # 切换到root账号以下操作可以在root下也可以在普通账号，但是ubuntu保存配置必须在root下.每次添加或者删除规则，务必保存配置，以免丢失.1、清空iptables所有配置（新系统操作）sudo iptab

现在CentOS要开始停止维护了，所以开始慢慢转向debian或者ubuntu；虽然大同小异，但是还是有些细节不一样，这里写一下Ubuntu脚本开机跟Redhat一样的启动方式。1、添加rc.local服务super@super:~$ sudo more /etc/systemd/system/rc-local.service[Unit]Description=rc.localConditionPathExists=/etc/rc.local [Service]Type=forkingEx
