/var/log/chrony Direktori Kosong di CentOS/RHEL

Pos ini menjelaskan mengapa /var/log/chrony folder kosong meskipun layanan chronyd dikonfigurasi dan berjalan.

# ls -l /var/log/chrony/

Status Chronyd menunjukkan berjalan:

# systemctl status chronyd
● chronyd.service - NTP client/server

Di file chrony.conf logdir juga diaktifkan/dikonfigurasi:

# cat /etc/chrony.conf |grep log
# Specify directory for log files.
logdir /var/log/chrony
# Select which information is logged.
#log measurements statistics tracking

Mengaktifkan log statistik Chrony

1. Direktori /var/log/chrony yang digunakan untuk menyimpan log statistik, secara default “pengukuran log ” parameter dikomentari (dinonaktifkan), untuk mengaktifkan log statistik.

2. Edit /etc/chrony.conf file dan batalkan komentar baris dimulai dengan "pengukuran log". Misalnya:

Dari:

# Select which information is logged.
#log measurements statistics tracking

Kepada:

# Select which information is logged.
log measurements statistics tracking

3. Mulai ulang layanan chronyd:

# systemctl restart chronyd

4. Sekarang daftar Direktori dan verifikasi:

# ls -l /var/log/chrony/
