nginx masuk ke access.log.1 alih-alih access.log, logrotate gagal?

Saya memiliki instance nginx yang diatur untuk mencatat akses ke /var/log/nginx/access.log dan kesalahan ke /var/log/nginx/errors.log, tetapi begitu logrotate berjalan setiap minggu, file tersebut dipindahkan ke * .log.1 dan file * .log baru akan dibuat, tetapi nginx terus log ke file log.1 alih-alih file .log baru (dan tidak ada yang di-gzip). Pertama kali saya perhatikan ini, sudah 3 minggu sejak rotasi log dan log semakin besar. Menjalankan kill -HUP `cat /run/nginx.pid`membuat nginx mulai masuk ke tempat yang tepat lagi, tetapi masalahnya dimulai lagi minggu berikutnya.

Alasan yang lebih penting ini membuat frustrasi adalah karena saya memiliki log yang diatur untuk mengunggah ke Loggly melalui rsyslog, dan ketika nginx berhenti masuk ke file saya memiliki polling rsyslog, maka hal-hal berhenti mengunggah dan saya tidak mendapatkan peringatan.

Saya curiga ada hubungannya dengan me-restart nginx, atau memuat ulang konfigurasi, karena itu tidak dimulai sampai saya membuat perubahan konfigurasi dan memuat ulang konfigurasi dengan cara yang saya pikir normal. Saya mencoba menjalankan kill -USR1 `cat /run/nginx.pid`tetapi file terus login ke lokasi yang salah sampai saya berlari kill -HUP `cat /run/nginx.pid`, yang saya sudah tahu tidak menyelesaikan masalah.

Adakah yang tahu apa yang terjadi? Saya akui saya bukan ahli dalam administrasi logrotate atau nginx, tetapi Google saya gagal dalam hal ini.

Ini adalah skrip nginx logrotate saya, dan beri tahu saya jika ada hal lain yang ingin Anda lihat. Nginx.conf tidak memiliki keistimewaan di dalamnya terkait dengan logging, selain mendefinisikan lokasi output.

/var/log/nginx/*.log {
        weekly
        missingok
        rotate 52
        compress
        delaycompress
        notifempty
        create 0640 www-data adm
        sharedscripts
        prerotate
                if [ -d /etc/logrotate.d/httpd-prerotate ]; then \
                        run-parts /etc/logrotate.d/httpd-prerotate; \
                fi \
        endscript
        postrotate
                [ -s /run/nginx.pid ] && kill -USR1 `cat /run/nginx.pid`
        endscript
}

EDIT: Saya pikir saya menemukan masalah. Ini adalah output dari menjalankan logrotate dalam mode debug:

$ sudo logrotate --force -d /etc/logrotate.d/nginx
reading config file /etc/logrotate.d/nginx

error: error opening /var/log/nginx/access.log.53.gz: No such file or directory

Namun, hanya ada arsip hingga sekitar * .log.8.gz, jadi logrotate gagal saat mencoba berinteraksi /var/log/nginx/access.log.53.gz. Kenapa dia mencoba melakukan itu? Saya kira saya perlu menyentuh file palsu untuk mengisinya? Sepertinya ini salah.

Bah, akhirnya saya menemukan jawabannya setelah lama menggali. Masalahnya, dalam kasus saya bukankah logrotate gagal. Pesan kesalahan itu baik-baik saja, dan tidak benar-benar menghentikan logrotate. Masalahnya adalah nginx tidak melepaskan pegangan file ke file log setelah menerima -USR1sinyal dari kill. Singkatnya, alasan tidak memuat ulang file log adalah karena /var/log/nginxfolder itu tidak dimiliki oleh pengguna yang sama dengan proses pekerja nginx (dimiliki oleh www-data, berjalan di bawah web). Saya tidak tahu bagaimana itu berubah (mungkin karena server ini dibuat ulang baru-baru ini), tetapi mengubah folder untuk dimiliki oleh pengguna yang sama dengan proses pekerja nginx (dan memperbaiki file logrotate untuk membuat log baru sebagai web) memperbaiki masalah ini.

Saya memiliki masalah yang sama di Ubuntu 14.04, tetapi setelah membaca jawaban Anda, saya memeriksa bahwa nginx saya berjalan di bawah www-data, yang memiliki folder, jadi ...

Namun, saya telah menemukan bug ini , yang menunjukkan kesalahan pada bagian postrotate di /etc/logrotate.d/nginx.

Untuk memperbaikinya, Anda dapat berkomentar

invoke-rc.d nginx rotate >/dev/null 2>&1

dan gunakan salah satu opsi berikut (dari komentar di bug itu) sebagai gantinya:

• start-stop-daemon --stop --signal USR1 --quiet --pidfile /run/nginx.pid --name nginx
• nginx -s reload
• layanan nginx reload> / dev / null 2> & 1

Penyebab lain untuk masalah ini mungkin mengisi disk .

CATATAN: Ini bahkan dapat terjadi dengan log akses yang mengisi tiba-tiba! Apakah mungkin?

Untuk mereproduksi ini, Anda mungkin memiliki log akses Anda mengisi secara tiba-tiba dengan banyak permintaan, setelah logrotatediaktifkan akan dipindahkan access.logke access.log.1, tetapi akan gagal untuk mengompres file berikutnya, dan karena itu gagal mengirim USR1sinyal ke nginx.

Bagaimana Anda memperbaiki masalahnya?

• Jika Anda peduli tentang pipa log file ke ssh + kompres di sana, kemudian bawa kembali. Pastikan untuk menganalisis apa yang menyebabkan akses atau kesalahan log terisi dengan cepat.
• Jika Anda tidak peduli, potong file dan muat ulang nginx atau hapus dan mulai ulang , pastikan TIDAK untuk menghapus dan memuat ulang karena ini tidak akan merilis inode (tolong jangan katakan pegangan , ini adalah istilah windows)
