Saya sudah systemd-unit
di sistem saya yang diaktifkan. Masalahnya adalah, itu tidak me-restart setelah reboot. Itu tergantung pada dua layanan lain yang keduanya dimulai seperti yang diharapkan.
Layanan ini dikenal, diaktifkan dan mati:
[centos@ansible-kube-4 ~]$ sudo systemctl status flanneld
flanneld.service - Flanneld overlay address etcd agent
Loaded: loaded (/usr/lib/systemd/system/flanneld.service; enabled)

reenable
mengoreksi sesuatu yang belum saya lakukan atau gagal dan tidak dapat melihat karena saya tidak cukup menyipit. Ngomong-ngomong, dari dua host identik yang saya konfigurasikan untuk membuat layanan saya muncul setelah reboot, satu berfungsi dan yang lain tidak sampai saya melakukan ini.Saya tidak menemukan bukti dalam konfigurasi Anda bahwa layanan ini harus dimulai pada saat boot.
systemd
memungkinkan dua cara mengaktifkan layanan sehingga dimulai saat boot:Atau:
Sebenarnya, yang pertama adalah cara lama untuk memanggil yang kedua, dan saya tidak yakin apakah
chkconfig
paket diinstal secara default, tetapi Anda dapat menginstalnya menggunakanapt-get
atauyum
.sumber
sudo systemctl enable flanneld
mengaktifkannya.systemctl enable servicename
. Sebagian besar contoh juga termasuk.service
penghentian dalam perintah, tetapi saya tidak yakin ini harus melakukan perbedaan.
