配置IP地址
1、自动获取IP地址
- dhclient
运行这条命令后，再使用ifconfig可以看到自动获取的ip地址
- [root@localhost ~]# ifconfig
- eth0 Link encap:Ethernet HWaddr 00:0C:29:D9:F0:52
- inet addr:10.72.137.85 Bcast:10.72.137.255 Mask:255.255.255.0
- inet6 addr: fe80::20c:29ff:fed9:f052/64 Scope:Link
- UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
- RX packets:27135 errors:0 dropped:0 overruns:0 frame:0
- TX packets:53 errors:0 dropped:0 overruns:0 carrier:0
- collisions:0 txqueuelen:1000
- RX bytes:3488498 (3.3 MiB) TX bytes:7550 (7.3 KiB)
- Interrupt:18 Base address:0x1080
-
- lo Link encap:Local Loopback
- inet addr:127.0.0.1 Mask:255.0.0.0
- inet6 addr: ::1/128 Scope:Host
- UP LOOPBACK RUNNING MTU:16436 Metric:1
- RX packets:0 errors:0 dropped:0 overruns:0 frame:0
- TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
- collisions:0 txqueuelen:0
- RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
2、手动配置IP
2.1 Centos6.x 配置
如果你的虚拟机不能自动获取IP，那么只能手动配置，配置方法为：
- vim /etc/sysconfig/network-scripts/ifcfg-eth0
- # 驱动网卡
- DEVICE=eth0
- # mak地址
- HWADDR=00:0C:29:44:D9:6D
- # 不锈钢
- TYPE=Ethernet
-
- UUID=ad62c4e2-14f9-4f1e-9721-fa5210e211c1
- # 开机启动
- ONBOOT=yes
-
- NM_CONTROLLED=yes
- # 静态IP
- BOOTPROTO=static
- # IP地址
- IPADDR=192.168.1.27
- # mark 地址
- NETMASK=255.255.255.0
- # 网关
- GATEWAY=192.168.1.1
- # DNS1
- DNS1=192.168.1.1
- # DNS2
- DNS2=114.114.114.114
3、重启网卡
网卡重启完成后，使用ifconfig查看配置的IP地址
- service network restart
4、Centos7.x配置方式
- vim /etc/sysconfig/network-scripts/ifcfg-enp3s0
- TYPE="Ethernet"
- # 静态IP
- BOOTPROTO="static"
- DEFROUTE="yes"
- #IPV4_FAILURE_FATAL="no"
- #IPV6INIT="yes"
- #IPV6_AUTOCONF="yes"
- #IPV6_DEFROUTE="yes"
- #IPV6_FAILURE_FATAL="no"
- # 网卡名称
- NAME="enp3s0"
- # 网卡id，默认不便
- UUID="1396ed1e-441b-4768-991b-1d76749cbae6"
- # 网卡名称
- DEVICE="enp3s0"
- # 开机自启动
- ONBOOT="yes"
- # 使用文件中的dns
- PEERDNS=yes
- PEERROUTES="yes"
- #IPV6_PEERDNS="yes"
- #IPV6_PEERROUTES="yes"
- #IPV6_PRIVACY="no"
- # 虚拟机IP
- IPADDR=192.168.1.10
- NETMASK=255.255.255.0
- # 网关
- GATEWAY=192.168.1.1
- # dns
- DNS1=192.168.1.1
- DNS2=114.114.114.114
