1.固定的可以联网ip地址
2.关闭防火墙
3.关闭selinux
4.光盘自动挂载
5.配置好本地yum源
RHEL6配置方法：
1.ifconfig 2.配置文件（永久） 3.setup/nmtui
1. ifconfig查看IP地址 crtl+l 清屏
RHEL中弱化了setup的功能，对于网络管理来说，network服务的
功能弱化，主要通过NetworkManager对网络进行管理
RHEL7通过nmtui修改网络配置（RHEL7默认安装，前提是需
要开启NetworkManager.service才可以使用）
首先，确定NetworkManager服务正常运行
systemctl status NetworkManager查看网络服务运行是否正常
systemctl start NetworkManager 启动networkmanager服务
第二种 vim /etc/sysconfig/network-scripts/ifcfg-
eno16777736
TYPE="Ethernet"
BOOTPROTO="none" ip地址类型：none static dhcp
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
NAME="eno16777736"
UUID="0ac62b8e-60b6-47ad-8967-c70369eeeaab"
DEVICE="eno16777736"
ONBOOT="yes" 是否启动
DNS1="8.8.8.8" DNS
IPADDR="192.168.1.63" IP地址
PREFIX= "24" 掩码长度
GATEWAY=192.168.1.1 默认网关
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_PRIVACY=no
关闭防火墙，开机自动关闭
rehl7 firewalld

防火墙的关闭与开机自动关闭
systemctl stop firewalld 关闭命令
[root@zq ~]# systemctl disable firewalld 禁用命令
Removed symlink /etc/systemd/system/dbus-

Removed symlink
/etc/systemd/system/basic.target.wants/firewalld.service.
关闭selinux并设置开机自动关闭
[root@zq ~]# setenforce 0 暂时关闭
usage: setenforce [ Enforcing | Permissive | 1 | 0 ]
[root@zq ~]# vim /etc/sysconfig/selinux 永久关闭
# 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 is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only
selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
重启生效 reboot
设置光盘开机自动挂载

配置yum源
二.yum的配置文件
yum的一切配置信息都储存在一个叫yum.repos.d的配置文件中，通常
位于/etc目录下这是整个yum系统的重中之重
vim /etc/yum.repos.d/rehl7.repo创建新的配置文件
[Server]
name=Red Hat Enterprise Linux Server
baseurl=file:///mnt 访问路径
enable=1 可以允许吗 可以 启用
gpgcheck=0 需要检查吗 不需要 取消验证
没有配置的先删除原有的文件
rm -fr /etc/yum.repos.d/*
创建文件 文件的形式 必须是.repo
