问题：动态IP时连接外网没有问题，但是将IP改为静态IP时发现没有办法连接外网

查看文件/etc/resolv.conf，里面的内容全部都被注释

[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文件中增加一行语句
[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

重启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

                                                           [  OK  ]

可以连接外网
[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
