Ubuntu 18 set a static IP

 

Use netplan command in Ubuntu 18

 

First of all

cd /etc/netplan/

* .Yaml find the file (each person may be different), edit it

root@waydeserver:/etc/netplan# vi 50-cloud-init.yaml

 

Modify the content in the following format:

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        ens33:
            addresses: [192.168.3.35/24]
            dhcp4: no
            dhcp6: no
            gateway4: 192.168.3.1
            nameservers:
                    addresses: [192.168.3.1]
    version: 2

 

• ens33 on behalf of the card name
• addresses on behalf of you want IP, 24 on behalf of 24-bit subnet mask, that is 255.255.255.0
• gateway4 represents the default gateway address
• nameservers on behalf of DNS, of course, be replaced by Google's 8.8.8.8, or domestic 114.114.114.114, etc.

 

Is one to pay attention to the indentation and spacing is very important , wrong, then it will not be correctly identified.

 

After modifying saved, then execute:

netplan apply

 

At this point you are finished, you can use the ifconfig command.
