1、配置ip并重启网卡:

[root@oracle ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.147.2
PREFIX=24
[root@oracle ~]# service network restart
Shutting down interface eth0:  Device state: 3 (disconnected)
                                                           [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  Active connection state: activated
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/7
                                                           [  OK  ]

2、关闭软件：

2.1、关闭Linux中的防火墙机制以及开启不启动

[root@oracle ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@oracle ~]# service ip6tables stop
ip6tables: Setting chains to policy ACCEPT: filter         [  OK  ]
ip6tables: Flushing firewall rules:                        [  OK  ]
ip6tables: Unloading modules:                              [  OK  ]
[root@oracle ~]# chkconfig  iptables off
[root@oracle ~]# chkconfig  ip6tables off

2.2、关闭Linux中的图形化网络管理机制以及开机不启动：

[root@oracle ~]# service NetworkManager  stop
Stopping NetworkManager daemon:                            [  OK  ]
[root@oracle ~]# chkconfig  NetworkManager off

2.3、关闭Linux中安全增强机制（selinux）以及开机不启动：

[root@oracle ~]# setenforce 0
[root@oracle ~]# cat  /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 is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

3、配置yum软件仓库(挂载镜像并修改yum文件)：

[root@oracle ~]# mount /dev/sr0 /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@oracle ~]# vim /etc/yum.repos.d/rhel-source.repo
[root@oracle ~]# yum repolist
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
aaa                                                                                 | 3.9 kB     00:00 ...
aaa/primary_db                                                                      | 3.1 MB     00:00 ...
repo id                                            repo name                                         status
aaa                                                123123                                            3,690
repolist: 3,690

4、配置主机名/映射关系：

[root@oracle ~]# hostname oracle
[root@oracle ~]# cat  /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=oracle
NTPSERVERARGS=iburst
[root@oracle ~]# cat  /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.147.2 oracle
