iptables防火墙和selinux
iptables
存在以下两种方式:
一、service方式
查看防火墙状态:
[root@centos6 ~]# service iptables status
iptables:未运行防火墙
开启防火墙: [root@centos6 ~]# service iptables start
关闭防火墙: [root@centos6 ~]# service iptables stop
二、iptables方式
先进入init.d目录,命令如下:
[root@centos6 ~]# cd /etc/init.d/
[root@centos6 init.d]#
然后 查看防火墙状态:
[root@centos6 init.d]# /etc/init.d/iptables status
暂时关闭防火墙:
[root@centos6 init.d]# /etc/init.d/iptables stop
重启iptables:
[root@centos6 init.d]# /etc/init.d/iptables restart
selinux
临时生效: getenforce 0
永久生效: 改配置文件 /etc/sysconfig/selinux
1 [root@oldboy /]# vi /etc/sysconfig/selinux 2 把SELINUX=enforcing 改成 disabled 3 4 [root@oldboy /]# cat /etc/sysconfig/selinux 5 6 # This file controls the state of SELinux on the system. 7 # SELINUX= can take one of these three values: 8 # enforcing - SELinux security policy is enforced. 9 # permissive - SELinux prints warnings instead of enforcing. 10 # disabled - No SELinux policy is loaded. 11 SELINUX=disabled 12 # SELINUXTYPE= can take one of these two values: 13 # targeted - Targeted processes are protected, 14 # mls - Multi Level Security protection. 15 SELINUXTYPE=targeted
