Steps
Refer to the following steps to use PublicDNS through the traditional DNS protocol:
tip
This document uses Ubuntu 22.04 LTS server edition as an example.
Change DNS settings in resolv.conf
In most cases, you can directly modify the DNS settings in resolv.conf.
- Open the /etc/nsswitch.conf file. Ensure the configuration of the hosts field is as follows:
- vim /etc/nsswitch.conf
-
- Open the /etc/resolv.conf file in edit mode.
- sudo vim /etc/resolv.conf
- If the file contains the nameserver parameter, you need to save the value of the nameserver field locally or record it manually on paper.
-
- Change the value of the nameserver field to the IPv4 address of the DNS server for VolcanoEngine PublicDNS. After making changes, save the content and exit.
-
Change DHCP settings
If your system uses DHCP Client, after the system is restarted, DHCP Client will automatically overwrite the configuration of the /etc/resolv.conf file. In this case, you need to refer to the following steps to set up the DHCP Client:
- Use edit mode to open the /etc/dhcp/dhclient.conf file.
sudo vim /etc/dhcp/dhclient.conf
- Locate the prepend domain-name-servers field.
-
- Remove the content before the prepend domain-name-servers field#Number. Enter the IPv4 address of the PublicDNS DNS server after domain-name-servers. Separate addresses using English commas,Separator. After making modifications, save the content and exit.
-
- Run sudo dhclient to reload the dhclient.conf file.
sudo dhclient
- Run the resolvectl status command to confirm that the DNS server address has been changed.
