1、問題：動態IP時連接外網沒有問題，但是將IP改為靜態IP時發現沒有辦法連接外網
查看文件/etc/resolv.conf，里面的內容全部都被注釋
[root@jenkins network-scripts]# more /etc/resolv.conf
# Generated by NetworkManager
# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com
在eth0文件中增加一行語句
[root@jenkins network-scripts]# vi ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
#BOOTPROTO=dhcp
IPADDR=192.168.0.173
IPV6INIT=no
NM_CONTROLLED=yes
ONBOOT=yes
TYPE=Ethernet
UUID="9086dd6f-6c00-49be-ad52-28ab87f2dcb7"
NAME="System eth0"
HWADDR=00:0c:29:c2:96:4a
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
USERCTL=no
DNS1=192.168.0.1
重啟network
[root@jenkins network-scripts]# 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/5
[ OK ]
可以連接外網
[root@jenkins network-scripts]# ping www.baidu.com
PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data.
64 bytes from 61.135.169.121: icmp_seq=1 ttl=54 time=2.51 ms
再次查看/etc/resolv.conf文件
[root@jenkins network-scripts]# more /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.0.1
2、問題
虛擬機關閉的狀態下進行了win10的更新，虛擬機打開之后處於沒網狀態，無法連接到橋接模式
首先將虛擬機掛起或者關閉
點擊編輯-->虛擬網絡編輯器
還原默認設置
之后點擊VMnet0
橋接到本地網卡即可
打開虛擬機，設置為橋接模式
