In Red Hat linux, after installing the linux system, set a fixed IP address for the NIC (two IP addresses are bound), and then configure the nic ip address in command mode. The configuration file is usually/etc/sysconfig/network-scripts/ifcfg-interface-name www.2cto.com 1. configure the nic ip address vi/etc/sysconfig/network-scripts/ifcfg-eth0 # Second Nic: vi/etc/sysconfig/network-scripts/ifcfg-eth1DEVICE = eth0 # physical device name IPADDR = 192.168.1.10 # IP address NETMASK = 255.255.255.0 # mask value NETWORK = 192.168.1.0 # network address (optional) BROADCAST = 192.168.1.255 # BROADCAST address (optional) GATEWAY = 192.168.1.1 # GATEWAY address ONBOOT = yes # [yes | no] (whether to activate the device during boot) USERCTL = no # [yes | no] (is it controllable for non-root users? BOOTPROTO = static # [none | static | bootp | dhcp] (Protocol not used during boot | static allocation | BOOTP protocol | DHCP protocol) 2. configure the Nic DNS configuration file in/etc/resolv. conf.

The network device configuration file of linux is stored in/etc/sysconfig/network-scripts. for the first Ethernet network device, the configuration file name is typically a ifcfg-eth0. To bind one more IP address to the first network device, create a file named ifcfg-eth0: 0 in the/etc/sysconfig/network-scripts directory, as shown in the following example: DEVICE = "eth0: 0" IPADDR = "211.100.10.119" NETMASK = "255.255.255.0" ONBOOT = "yes" where DEVICE is the DEVICE name and IPADDR is the IP address of the DEVICE, NETMASK is a subnet mask, and ONBOOT indicates that it is automatically started when the system starts. If you need to bind another IP address, you only need to add one of the file name and the eth0 in the DEVICE in the file. LINUX supports up to 255 IP aliases.
