虚拟机ping不同网络的解决方法

有时候我们的虚拟机无法ping通网络，今天来总结一下方法

 

 1.虚拟机安装之后，首先要进行网络的虚拟编辑器对网络进行编辑。（编辑nat模式喝DHCP）

 

 

2.配置文件的编写

如果想要自动获取IP .需要配置为DHCP

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno16777736
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
UUID=15294072-06e3-48d6-91c0-01e732b2a77e
DEVICE=eno16777736
ONBOOT=yes
#GATEWAY=192.168.253.2
#DNS1=144.144.144.144
#DNS2=8.8.8.8
#NETMASK=255.255.255.0

 

4.重启网卡

[root@localhost ~]# /etc/init.d/network start

 

5，查看IP（如果没有出现ip 用dhclient,重新获取一下IP）

[root@localhost ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:c5:6c:c3 brd ff:ff:ff:ff:ff:ff
    inet 192.168.253.130/24 brd 192.168.253.255 scope global dynamic eno16777736
       valid_lft 1483sec preferred_lft 1483sec
    inet6 fe80::20c:29ff:fec5:6cc3/64 scope link 
       valid_lft forever preferred_lft foreve6.

 

6安装ifconfig 

[root@localhost ~]# yum install net-tools -y
