centos6.5虚拟机安装后,没有iptables配置文件

openstack环境里安装centos6.5系统的虚拟机,安装好后,发现没有/etc/syscofig/iptables防火墙配置文件。

解决办法如下:

[root@kvm-server005 ~]# iptables -P OUTPUT ACCEPT [root@kvm-server005 ~]# /etc/init.d/iptables save iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]

这样,/etc/sysconfig/iptables配置文件就有了 [root@kvm-server005 ~]# cat /etc/sysconfig/iptables # Generated by iptables-save v1.4.7 on Wed Aug 31 01:14:57 2016 *filter :INPUT ACCEPT [43:3196] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [23:2380] COMMIT # Completed on Wed Aug 31 01:14:57 2016

再补充点其他内容配置: [root@kvm-server005 ~]# cat /etc/sysconfig/iptables # Generated by iptables-save v1.4.7 on Wed Aug 31 01:14:57 2016 *filter :INPUT ACCEPT [43:3196] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [23:2380] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -s 192.168.1.0/24 -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT # Completed on Wed Aug 31 01:14:57 2016 [root@kvm-server005 ~]# /etc/init.d/iptables restart iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] iptables: Applying firewall rules: [ OK ] [root@kvm-server005 ~]#
