Configure DNS server logs in Linux

In Linux, it also provides a popular BIND server, which is the most commonly used server software for building DNS servers. There are many articles about BIND installation. Now let's talk about the maintenance topic.

How can we understand the running status of the DNS server? Is it busy and load-intensive? All this is important for system administrators.

# Touch/var/named/chroot/var/named. log

# Chown named. named/var/named/chroot/var/named. log

# Chmod 755/var/named/chroot/var/named. log

# Service named restart

Make sure that selinux is disabled (View/etc/sysconfig/selinux configuration information)

Check whether the collected/var/named/chroot/var/named. log has any fault information.
