1、进入network-scripts目录并且查看该目录下存在的ifcfg-xx文件
cd/etc/sysconfig/network-scripts#xx为用户自己目录下的ifcfg-xx文件vim/etc/sysconfig/network-scripts/ifcfg-xx
2.修改如下配置内容
BOOTPROTO=static#将dncp改为staticONBOOT="yes"#开机时启用本配置IPADDR=192.168.13.131#静态ipGATEWAY=192.168.13.2#默认网关NETMASK=255.255.255.0#子网掩码DNS1=192.168.13.2#DNS配置
3.修改后ifcfg-ens33文件内容如下
TYPE="Ethernet"DEFROUTE=yesIPV4_FAILURE_FATAL="no"IPV6INIT="yes"IPV6_AUTOCONF="yes"IPV6_DEFROUTE="yes"IPV6_FAILURE_FATAL="no"IPV6_ADDR_GEN_MODE="stable-privacy"NAME="ens33"UUID="c40937f7-ebf8-41e8-8541-d79fc3dff61e"DEVICE="ens33"PREFIX=24IPV6_PEERDNS=yesIPV6_PEERROUTES=yesBOOTPROTO=static#将dncp改为staticONBOOT="yes"#开机时启用本配置DNS1=192.168.13.2#DNS配置IPADDR=192.168.13.131#静态ipNETMASK=255.255.255.0#子网掩码GATEWAY=192.168.13.2#默认网关
4.重启网络服务
servicenetworkrestart
5.查看改动后的效果，使用ifconfig或者ipaddr
ifconfig#输出结果如下ens33:flags=4163<UP,BROADCAST,RUNNING,MULTICAST>mtu1500inet192.168.13.131netmask255.255.255.0broadcast192.168.13.255inet6fe80::c43e:1e6b:69b:5ba8prefixlen64scopeid0x20<link>ether00:0c:29:9e:22:ebtxqueuelen1000(Ethernet)RXpackets6763bytes520694(508.4KiB)RXerrors0dropped0overruns0frame0TXpackets2700bytes541708(529.0KiB)TXerrors0dropped0overruns0carrier0collisions0lo:flags=73<UP,LOOPBACK,RUNNING>mtu65536inet127.0.0.1netmask255.0.0.0inet6::1prefixlen128scopeid0x10<host>looptxqueuelen1(LocalLoopback)RXpackets0bytes0(0.0B)RXerrors0dropped0overruns0frame0TXpackets0bytes0(0.0B)TXerrors0dropped0overruns0carrier0collisions0virbr0:flags=4099<UP,BROADCAST,MULTICAST>mtu1500inet192.168.122.1netmask255.255.255.0broadcast192.168.122.255ether52:54:00:96:18:0etxqueuelen1000(Ethernet)RXpackets0bytes0(0.0B)RXerrors0dropped0overruns0frame0TXpackets0bytes0(0.0B)TXerrors0dropped0overruns0carrier0collisions0ipaddr#输出如下1:lo:<LOOPBACK,UP,LOWER_UP>mtu65536qdiscnoqueuestateUNKNOWNqlen1link/loopback00:00:00:00:00:00brd00:00:00:00:00:00inet127.0.0.1/8scopehostlovalid_lftforeverpreferred_lftforeverinet6::1/128scopehostvalid_lftforeverpreferred_lftforever2:ens33:<BROADCAST,MULTICAST,UP,LOWER_UP>mtu1500qdiscpfifo_faststateUPqlen1000link/ether00:0c:29:9e:22:ebbrdff:ff:ff:ff:ff:ffinet192.168.13.131/24brd192.168.13.255scopeglobalens33valid_lftforeverpreferred_lftforeverinet6fe80::c43e:1e6b:69b:5ba8/64scopelinkvalid_lftforeverpreferred_lftforever3:virbr0:<NO-CARRIER,BROADCAST,MULTICAST,UP>mtu1500qdiscnoqueuestateDOWNqlen1000link/ether52:54:00:96:18:0ebrdff:ff:ff:ff:ff:ffinet192.168.122.1/24brd192.168.122.255scopeglobalvirbr0valid_lftforeverpreferred_lftforever4:virbr0-nic:<BROADCAST,MULTICAST>mtu1500qdiscpfifo_fastmastervirbr0stateDOWNqlen1000link/ether52:54:00:96:18:0ebrdff:ff:ff:ff:ff:ff
