RED hat 还是老的Linux

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
查看命令及状态		systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded

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-

org.fedoraproject.FirewallD1.service.
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
 一切皆文件
[root@zq ~]# mount -a  验证

配置挂载文件

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

[root@zq ~]# yum clean all
