Perlu dicatat bahwa upaya telah dilakukan untuk mengaktifkansystemctl enable monit

Fakta menunjukkan bahwa/var/www/html/nfsadalah folder yang dipasang ke drive jaringan melalui NFS.

Monit dimulai sebelum NFS, jadi foldernya belum ada, menyebabkan kesalahan monitError opening the log file '/var/www/html/nfs/monit/stage-web-1.log' for writing -- No such file or directory.

Bagaimana mengatasi hilangnya monit startup monitoring proses monit.service gagal.?

Solusinya adalah mengedit/lib/systemd/system/monit.service:

[Unit]
Description=Pro-active monitoring utility for unix systems
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/monit -I
ExecStop=/usr/bin/monit quit
ExecReload=/usr/bin/monit reload

[Install]
WantedBy=multi-user.target

dan tambahkannfs.serviceUntuk ituAfterDi belakang.Hasil akhirnya terlihat seperti ini:

[Unit]
Description=Pro-active monitoring utility for unix systems
After=network.target nfs.service

[Service]
Type=simple
ExecStart=/usr/bin/monit -I
ExecStop=/usr/bin/monit quit
ExecReload=/usr/bin/monit reload

[Install]
WantedBy=multi-user.target

Monitor Monit sekarang dapat memulai dengan sukses saat boot.
