How to Set Static IP Address on Ubuntu Server 22.04
|
|||
|
|
======
|
|||
|
|
In this post, we will cover how to set static ip address on Ubuntu server 22.04.
|
|||
|
|
|
|||
|
|
It is highly recommended to have a static ip on linux server because it would be persistent across the reboot. Static IP plays an important role for servers like Mail Server, Web Server and File server etc.
|
|||
|
|
|
|||
|
|
##### Prerequisites
|
|||
|
|
|
|||
|
|
* Minimal Installed Ubuntu Server 22.04
|
|||
|
|
* Regular User with sudo admin rights
|
|||
|
|
|
|||
|
|
In Ubuntu server 22.04, networking is controlled by netplan utility, so we will use netplan to configure static ip address on Ubuntu server.
|
|||
|
|
|
|||
|
|
Note: we cannot use [nmcli utiltity][1] as it is not the part of default installation on Ubuntu server.
|
|||
|
|
|
|||
|
|
### Setting up Static IP address on Ubuntu Server 22.04
|
|||
|
|
|
|||
|
|
Login to your Ubuntu server 22.04, look for the netplan configuration file. It is located under /etc/netplan directory.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ cd /etc/netplan/
|
|||
|
|
$ ls -l
|
|||
|
|
total 4
|
|||
|
|
-rw-r--r-- 1 root root 116 Oct 12 04:03 00-installer-config.yaml
|
|||
|
|
$
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Run below cat command to view the contents of ‘00-installer-config.yaml’
|
|||
|
|
|
|||
|
|
Note: Name of configuration file may differ as your per setup. As it is an yaml file, so make sure to maintain the indentation and syntax while editing.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ cat 00-installer-config.yaml
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Output,
|
|||
|
|
|
|||
|
|
![Default-Content-netplan-ubuntu-server][2]
|
|||
|
|
|
|||
|
|
As per above output, it says that we have ens33 interface and it is getting ip from dhcp server. Alternate way to view interface name is via ip command.
|
|||
|
|
|
|||
|
|
Now, to configure static ip in place of dhcp, edit netplan configuration file using vi or nano editor and add the following content.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ sudo vi 00-installer-config.yaml
|
|||
|
|
# This is the network config written by 'subiquity'
|
|||
|
|
network:
|
|||
|
|
renderer: networkd
|
|||
|
|
ethernets:
|
|||
|
|
ens33:
|
|||
|
|
addresses:
|
|||
|
|
- 192.168.1.247/24
|
|||
|
|
nameservers:
|
|||
|
|
addresses: [4.2.2.2, 8.8.8.8]
|
|||
|
|
routes:
|
|||
|
|
- to: default
|
|||
|
|
via: 192.168.1.1
|
|||
|
|
version: 2
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
save and close the file.
|
|||
|
|
|
|||
|
|
![Updated-Netplan-Config-File-Content-Ubuntu-Server][3]
|
|||
|
|
|
|||
|
|
In the above file we have used following,
|
|||
|
|
|
|||
|
|
* ens33 is the interface name
|
|||
|
|
* addresses are used to set the static ip
|
|||
|
|
* nameservers used to specify the DNS server ips
|
|||
|
|
* routes used to specify the default gateway
|
|||
|
|
|
|||
|
|
Note: Change the IP details and interface name as per your environment.
|
|||
|
|
|
|||
|
|
To make above changes into the effect the apply these changes using following netplan command,
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ sudo netplan apply
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Run following ip command to view the ip address on interface,
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ ip addr show ens33
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
To view the default route, run
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ ip route show
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Output of above commands,
|
|||
|
|
|
|||
|
|
![ip-addr-route-command-output-ubuntu-server][4]
|
|||
|
|
|
|||
|
|
Perfect, above commands’ output confirms that static ip and route has been configured successfully.
|
