How to activate or enable query log bind (named) centOS 7

Pertama cek terlebih dahulu, query log di service named kita sudah aktif atau belum dengan mengetikan command berikut :

[root@ns2 ~]# sudo rndc status
version: 9.9.4-RedHat-9.9.4-38.el7_3.3 <id:8f9657aa>
CPUs found: 1
worker threads: 1
UDP listeners per interface: 1
number of zones: 59
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 0/0/1000
tcp clients: 0/100
server is up and running

Jika hasilnya query logging is OFF, maka kita hanya mengaktifkan nya dengan menggunakan command berikut :

#rndc querylog

[root@ns2 ~]# rndc status
version: 9.9.4-RedHat-9.9.4-38.el7_3.3 <id:8f9657aa>
CPUs found: 1
worker threads: 1
UDP listeners per interface: 1
number of zones: 58
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is ON
recursive clients: 6/0/1000
tcp clients: 1/100

server is up and running

Untuk mengecek hasil dari query logging, kita cukup menggunakan command berikut :

#tail -f /var/log/messages
