/var/log/nginx/access.logへのアクセスとエラーを/var/log/nginx/errors.logに記録するように設定されたnginxインスタンスがありますが、logrotateが毎週実行されるとすぐにファイルが移動します*。初めてこれに気づいたとき、ログのローテーションから3週間が経過し、ログが巨大になっていました。実行kill -HUP `cat /run/nginx.pid`
すると、nginxは再び適切な場所へのロギングを開始しましたが、問題は次の週に再び始まりました。
これがイライラするより重要な理由は、rsyslogを介してLogglyにアップロードするように設定されたログがあり、nginxがファイルへのロギングを停止するとrsyslogポーリングが発生し、アップロードが停止し、アラートが表示されないことです。
私はそれがnginxを再起動するか、設定をリロードすることと関係があるのではないかと疑っています。実行しようとしましたkill -USR1 `cat /run/nginx.pid`
が、実行するまでファイルは間違った場所に記録され続けましたがkill -HUP `cat /run/nginx.pid`
、問題は解決しません。
何が起こっているのでしょうか?私はlogrotateまたはnginxの管理の専門家ではないことを認めていますが、私のGoogleはこれに関して私に失敗しました。
ここに私のnginx logrotateスクリプトがあります。他に見たいものがあるかどうか教えてください。nginx.confには、出力場所の定義以外に、ロギングに関して特別なものはありません。
