Set static IP addresses in Linux

(1) The intuitive way is: if you use the fedora system, enter setup in the command line and enter the static IP address according to the wizard, refer to my article "Building a NAT test environment for VMware Workstation"

(2) modify the configuration file and enter
Vim/etc/sysconfig/network-Script
S/ifcfg-eth0

Device = eth0
Onboot = Yes
Bootproto = static
Ipaddr = 192.168.0.3
Netmask = 255.255.255.0
Gateway = 192.168.0.1

Device = eth0 <-- Device

Onboot = Yes <-- whether to start automatically

Bootproto = static <-- whether to use a static IP Address

Ipaddr = XXX. XX <-- your IP address

Netmask = 255.255.255.0 <-- your subnet mask

Gateway = 192.168.0.1 <-- your gateway

Make the IP address take effect:
/Sbin/ifdown eth0
/Sbin/IFUP eth0

Configure DNS resolution
Echo "nameserver 211.98.1.28">/etc/resolv. conf

Notify gateway to update information:
/Etc/init. d/network restart

DNS is the domain name
System, which can convert a domain name such as www.21php.com to an IP address such as 211.152.50.35; without DNS, browse 21php.com
This website must be accessed with numbers as hard to remember as 211.152.50.35. The DNS server provides the DNS service. DNS servers can be divided into three types: high-speed cache servers
(Cache-only server), master server (Primary name server), and secondary server (second name server ).
