There is only one lo 127.0.0.1 address. Therefore, you need to manually edit the configuration file for the system to load a local connection. you can select DHCP or manual. There are a lot of files under the/etc/sysconfig/network-script directory, where the ifcfg-eth0 is the file to be modified. Www.2cto.com DEVICE = "eth0" # manually specify the IP address IPADDR = "192.168.10.200" # subnet mask NETMASK = "255.255.255.0" # GATEWAY = "192.168.10.1" # static ip bootproto = "static" HWADDR = ""08: 00: 27: 25: EC: 5A "NM_CONTROLLED =" yes "ONBOOT =" yes "TYPE =" Ethernet "UUID =" f10dd2b3-2ec3-467c-937b-bc5a1e1d063c "if you need to automatically obtain the IP address through DHCP, so: DEVICE = "eth0" # comment out the following three lines # IPADDR = "192.168.10.200" # NETMASK = "255.255.255.0" # GATEWAY = "192.168.10.1" # declare using dhcp to obtain IPBOOTPROTO = "dhcp" HWAD DR = "08: 00: 27: 25: EC: 5A" NM_CONTROLLED = "yes" ONBOOT = "yes" TYPE = "Ethernet" UUID = "f10dd2b3-2ec3-467c-937b-bc5a1e1d063c" after saving, you can use the service network restart command to restart the network service. Modify the DNS configuration file/etc/resolv. conf. it is very simple: After the nameserver 8.8.8.8nameserver 192.168.10.196 is saved, run the service network restart command to restart the network service.
