Linux network setting tips: how to bind multiple IP addresses to a network card?

Article title: Linux network settings tips: how to bind multiple IP addresses to a network card ?. 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.
The network device configuration file of Linux is stored in/etc/sysconfig/network-scripts. for the first network device of Ethernet, the configuration file name is typically a ifcfg-eth0 if you need to bind one more IP address to the first network device, you just need to create a file named ifcfg-eth0: 0 in the/etc/sysconfig/network-scripts directory, content example:
DEVICE = "eth0: 0"
IPADDR = "211.100.10.119"
NETMASK = "255.255.255.0"
ONBOOT = "yes"
DEVICE indicates the DEVICE name, IPADDR indicates the IP address of the DEVICE, NETMASK indicates the subnet mask, and ONBOOT indicates automatic start at system startup.
If you need to bind another IP address, you only need to add the file name to the eth0: x of the DEVICE in the file. LINUX supports up to 255 IP aliases.
