Ubuntu DNS restart failure Modification

Ubuntu DNS restart failure Modification

Ubuntu 15.04 directly Modifies/etc/resolv. conf, And the configuration is lost after the DNS is restarted.

Correct method:

1. # Vim/etc/network/interfaces, add "dns-nameservers 223.5.5.5" to the end of the file"

   Restart systemctl restart networking. service and test OK.

2. # Vim/etc/resolvconf/resolv. conf. d/base (the file is empty by default)

   Nameserver 223.5.5.5

   Nameserver 223.6.6.6

   # Resolvconf-u (update to resolv. conf)

   # More/etc/resolv. conf

   # Dynamic resolv. conf (5) file for glibc resolver (3) generated by resolvconf (8)

   # Do not edit this file by hand -- YOUR CHANGES WILL BE OVERWRITTEN

   Nameserver 223.5.5.5

   Nameserver 223.6.6.6

   You do not need to restart the NIC/system. Test OK. After the system is restarted, OK.
