1.进入/etc/sysconfig/network-scripts，修改网卡配置文件ifcfg-eno16777736
2.修改网络配置
修改前
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="6b7fc8a3-2b38-45e3-a64d-485a89380d48"
DEVICE="eno16777736"
ONBOOT="yes"
修改后
TYPE="Ethernet"
BOOTPROTO="static"----dhcp（自动获取ip）改为static（静态ip）
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="ea3e99ab-fb3e-4724-8a6b-e072a058bdcd"
DEVICE="eno16777736"
ONBOOT="yes"
BROADCAST=192.168.159.255---局域网广播地址
IPADDR=192.168.159.131---静态IP
NETMASK=255.255.255.0----子网掩码
GATEWAY=192.168.159.2----网关或者路由地址
DNS1=192.168.159.2---DNS
3、检查路由
route -n-----若无通过route add default gw 192.168.159.2添加
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.159.2 0.0.0.0 UG 100 0 0 eno16777736
192.168.159.0 0.0.0.0 255.255.255.0 U 100 0 0 eno16777736
4.检查dns
cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.159.2
5.成功前网络服务
/etc/init.d/network restartLinux配置静态IP
