1、配置环境：存储厂家：Infortrend主机系统：CentOS6.0目 录1、关闭防火墙步 12、彻底关闭 SELinux .23、开机网卡启动, 设置固定 IP34、开启 SSh45、 device-mapper-multipath 安装与配置 45.1 挂载光驱 45.2 多路径安装： 45.3 检查安装情况 55.5 创建多路径文件 55.6 将多路径软件 multipath 设置为开机启动 .65.7 修改多路径配置文件： 65.8 格式化 mpathap1 和 mpathap2 85.9 挂在分区： 86、 DD 测试 91、关闭防火墙步关闭命令： service iptables
2、stop 永久关闭防火墙：chkconfig iptables off 两个命令同时运行，运行完成后查看防火墙关闭状态 ：service iptables statusrootlocalhost # service iptables stopiptables：清除防火墙规则： 确定iptables：将链设置为政策 ACCEPT：filter 确定iptables：正在卸载模块： 确定rootlocalhost # chkconfig iptables offrootlocalhost # service iptables statusiptables：未运行防火墙。rootlocalhost
3、#2、彻底关闭 SELinuxrootlocalhost etc# vi /etc/selinux/config # This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing - SELinux security policy is enforced.# permissive - SELinux prints warnings instead of enforcing.# disabled - No SELinux policy
4、is loaded.#SELINUX=enforcing-前面加个#号注释掉它# SELINUXTYPE= can take one of these two values:# targeted - Targeted processes are protected,# mls - Multi Level Security protection.SELINUXTYPE=disabled-修改为 disabled“selinux/config“ 13L, 458C writtenrootlocalhost etc#保存，退出，重启系统，搞定。3、开机网卡启动, 设置固定 IProotlocalho
