Article title: modify the gateway in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Take the root user as an example and execute the following command:
# Route add default gw xxx. xxx (IP address of the Gateway)
To change the gateway, edit the/etc/sysconfig/network-scripts/ifcfg-eth0 file, modify the corresponding gateway settings, and run the following command:
#/Etc/init. d/network restart
Directly use the command line to modify the Gateway address:
# Vi/etc/sysconfig/network
NETWORKING = yes
NETWORKING_IPV6 = yes
HOSTNAME = localhost. localdomain
GATEWAY = 192.168.0.1
How do I change the LINUX IP address?
Ifconfig eth0 New ip
Then edit/etc/sysconfig/network-scripts/ifcfg-eth0 and modify the ip
