registrazione nginx su access.log.1 invece di access.log, logrotate fallito?

Ho un'istanza nginx che è impostata per accedere a /var/log/nginx/access.log e gli errori su /var/log/nginx/errors.log, ma non appena logrotate viene eseguito ogni settimana, il file viene spostato in * .log.1 e il nuovo file * .log vengono creati, ma nginx continua ad accedere al file log.1 anziché al nuovo file .log (e nulla viene compresso con gzip). La prima volta che l'ho notato, erano passate 3 settimane dalla rotazione del registro e il registro stava diventando enorme. L'esecuzione di kill -HUP `cat /run/nginx.pid`nginx ha fatto ricominciare a registrare nel posto giusto, ma il problema è ricominciato la settimana successiva.

Il motivo più importante per cui è frustrante è che ho i registri impostati per il caricamento su Loggly tramite rsyslog e quando nginx interrompe la registrazione nel file ho il polling di rsyslog, quindi le cose interrompono il caricamento e non ricevo alcun avviso.

Ho il sospetto che abbia qualcosa a che fare con il riavvio di nginx o il ricaricamento della configurazione, perché non è iniziato fino a quando non ho apportato una modifica alla configurazione e ricaricato la configurazione in un modo che pensavo fosse normale. Ho provato a correre kill -USR1 `cat /run/nginx.pid`ma i file hanno continuato ad essere registrati nella posizione sbagliata fino a quando non sono stato eseguito kill -HUP `cat /run/nginx.pid`, che già so non risolve il problema.

Qualche idea di cosa sta succedendo? Devo ammettere di non essere un esperto di logrotate o amministrazione di nginx, ma i miei google mi hanno fallito in questo.

Ecco il mio script nginx logrotate e fammi sapere se c'è qualcos'altro che potresti voler vedere. Il nginx.conf non ha nulla di speciale in ciò che riguarda la registrazione, a parte la definizione dei percorsi di 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: penso di aver trovato il problema. Ecco l'output dell'esecuzione di logrotate in modalità debug:

$ sudo logrotate --force -d /etc/logrotate.d/nginx

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

Tuttavia, ci sono solo archivi fino a circa * .log.8.gz, quindi logrotate fallisce quando tenta di interagire con /var/log/nginx/access.log.53.gz. Perché mai sta provando a farlo? Suppongo di dover toccare i file falsi per compilarlo? Questo sembra sbagliato in qualche modo.

Bah, ho finalmente trovato la risposta dopo tanto tempo a scavare. Il problema, nel mio caso, non era che logrotate stava fallendo. Quel messaggio di errore va bene e in realtà non si ferma logrotate. Il problema era che nginx non stava rilasciando l'handle del file nel file di registro alla ricezione del -USR1segnale da kill. Per farla breve, la ragione per cui non stava ricaricando i file di registro era perché la /var/log/nginxcartella non era di proprietà dello stesso utente dei processi di lavoro nginx (di proprietà di www-data, in esecuzione sul web). Non ho idea di come sia cambiato (forse perché questo server è stato rifatto di recente), ma cambiando la cartella in modo che appartenga allo stesso utente dei processi di lavoro nginx (e correggendo il file logrotate per creare nuovi registri come web) risolto il problema.

Ho lo stesso problema in Ubuntu 14.04, ma dopo aver letto la tua risposta, ho verificato che il mio nginx fosse in esecuzione su www-data, che possiede la cartella, quindi ...

Tuttavia, ho trovato questo errore , che indica l'errore nella sezione postrotate in /etc/logrotate.d/nginx.

Per risolvere il problema, puoi commentare

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

e utilizzare invece una delle seguenti opzioni (dai commenti in quel bug):

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

Un'altra causa di questo problema potrebbe essere il riempimento del disco .

NOTA: ciò può accadere anche quando il registro di accesso si riempie improvvisamente! Forse?

Per riprodurre questo si può avere il pieno log di accesso su tutto ad un tratto, con molte richieste, una volta logrotateincendi si si sposterà access.loga access.log.1, ma non riuscirà a comprimere il file successivo, e quindi riuscire a inviare il USR1segnale al nginx.

Come risolvi il problema?

• Se ti interessano i log, reindirizza il file su ssh + compress lì, quindi riportalo indietro. Assicurati di analizzare cosa ha causato il riempimento degli accessi o dei log degli errori così rapidamente.
• Se non vi interessa, tronca il file e ricarica nginx o cancellare e riavviare , assicurarsi non per cancellare e ricarica come questo non rilascerà l'inode (si prega di non dire la maniglia , si tratta di un termine di Windows)
