WordPress Nginx + php-fpmおよびその他の問題で画像のサイズを変更しない

Question

最近、UbuntuLoCoチームのWordPressブログ用に、512mb/1ghz CPU、Nginx + php-fpm + Varnish + APC + PerconaのMySQLサーバー+ CloudFlareProを搭載したUbuntu12.04VPSをセットアップしました。 1日あたり3〜4kのヒット、約180MBと8〜20％のCPUを使用します。すべてがめちゃくちゃ速く動作しているようです...ページの読み込みは非常に優れており、競合他社の約16倍高速です...しかし1つの問題があります。

画像をアップロードするとき、WordPressサイズを変更しないでください。そうすれば、画像全体を投稿に挿入できます。たとえば、画像のサイズが30kbの場合、サイズは適切に変更されます。 ..しかし、画像が100kb以上の場合、それは...

Nginxエラーログにこれが表示されます：

upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "POST /wp-admin/async-upload.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", Host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/wp-admin/media-upload.php?post_id=2668&"

それは問題に関連しているようですが、私は知りません。そのタイムアウトが発生したとき、私も投稿を表示しようとしているときにそれを取得し始めました：

upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "GET /tutoriais-gimp-6-adicionando-aplicando-novos-pinceis.html HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", Host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/"

そして、php5-fpmを再起動するだけで修正されます。

タイムアウトなどを増やしてみましたが、うまくいきませんでしたので、まだわからなかった制限があると思います。誰かがそれを手伝ってくれませんか？

また、W3 Total Cacheのページキャッシュ（ディスク拡張）を使用すると、フロントページで404エラーが発生し始めました。それはいつか前までうまくいきました、そして、どこからともなく、それは起こり始めました。今夜、モバイルプラグインを無効にし、W3 Total Cacheのみをアクティブにして、それらと競合していないかどうかを確認します...

そして、これをすべて完了するために、私はこのエラーを受け取っています：

PHP Warning:  apc_store(): Unable to allocate memory for pool. in /var/www/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.php on line 41

すでにAPC設定を変更しましたが、成功しませんでした。だから...誰かがそれらの問題で私を助けてくれますか？

ああ...それが助けになるなら、私はPHPこのようにインストールしました：

Sudo apt-get install php5-fpm php5-suhosin php-apc php5-Gd php5-imagick php5-curl

そして公式PPAのNginx。私の悪い英語とあなたの時間の人々に感謝します！ （：

Answer 1

エラーは、PHPバックエンドが妥当な時間枠で応答できないことを示しています。 php-fpmに直接制限はありませんが、max_execution_timeとmax_input_timeが私の最初の推測です。
