• 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
