一步一步学习RHEL7之环境搭建

Posted 2020-07-04

一、配置IP地址

    RHEL7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

     [[email protected] ~]#systemctl status NetworkManager

         NetworkManager.service - Network Manager

         Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service;enabled; vendor preset: enabled)

         Active: active (running)since 二 2016-01-26 20:05:49CST; 43min ago

    如果没有启动，手动启动

    [[email protected] ~]#systemctl restart  NetworkManager

    查看IP地址

    [[email protected] ~]#ifconfig

   修改IP地址

   [[email protected] ~]#nmtui-edit eno16777735

  激活网络配置                                      

  [[email protected] ~]#nmtui

或者

[[email protected] ~]#systemctl restart network

二、关闭防火墙并设置开机自动关闭

[[email protected] ~]#systemctl stop firewalld

[[email protected] ~]#systemctl disable firewalld

Removed symlink/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

Removed symlink/etc/systemd/system/basic.target.wants/firewalld.service.

 

三、关闭selinux并设置开机自动关闭

[[email protected] ~]#setenforce 0                          #临时关闭

 

开机自动关闭：

[[email protected] ~]# sed-i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config

四、设置光盘开机自动挂载

[[email protected] ~]#echo "/dev/sr0 /mnt iso9660 defaults 0 0"  >> /etc/fstab

五、配置好本地yum源

[[email protected] ~]# rm-rf /etc/yum.repos.d/*

[[email protected] ~]# cat> /etc/yum.repos.d/rhel7.repo <<EOF

> [rhel7-source]

> name=rhel-source

>baseurl=file:///mnt

> enabled=1

> gpgcheck=0

> EOF

 

[[email protected] ~]# yumclean all                                      #清空yum缓存

[[email protected] ~]# yumlist                                              #生成缓存列表
