2016/07/30(土)さくらのレンタルサーバーにPHP7を導入

2016年12月14日からPHP7.1が使用できるようになったので、この作業をする必要は無くなりました。→さくらのレンタルサーバ PHP7.1 提供開始のお知らせ | さくらインターネット

さくらのレンタルサーバーにPHP7を導入

さくらのレンタルサーバーがなかなかPHP7に対応しないので自力でインストールしてみました。

注意:この方法でPHP7を導入した後は、自身の責任においてセキュリティーアップデート(最新版の再導入)をしてください。

事前準備

サーバー上でビルドするのでSSHでアクセスできるようにしておきます。

ライトプランではSSHが使えないので、telnet.cgiを使うなどしてCGI経由で作業します。

  • telnet.cgi
    • 他人に使われると非常に危険なので、アクセス制限しておき、作業後は削除してください。

PHP7のビルド

サーバーに負荷がかかるのでアクセスが少ない時間帯に実施した方が無難です。「<アカウント名>」は、自身のアカウント名に置き換えてください。

現時点の最新版のPHP7.0.9での手順になっています。

  1. 作業ディレクトリとインストール先にするディレクトリを作成。
    cd /home/<アカウント名>/
    mkdir usr work
    
  2. PHP7のダウンロードと展開
    cd work
    wget --trust-server-names http://jp2.php.net/get/php-7.0.9.tar.bz2/from/this/mirror
    tar jxvf php-7.0.9.tar.bz2
    
  3. 以下の内容のファイルを作成し、展開ディレクトリ(/home/<アカウント名>/work/php-7.0.9)内にアップロードしておきます。(長いのでスクリプトファイルにしただけなので、直接configureを実行しても大丈夫だと思います。)
    #!/bin/sh
    ./configure \
      --prefix=/home/<アカウント名>/usr \
      --with-config-file-path=/home/<アカウント名>/usr/etc \
      --enable-mbstring \
      --enable-zip \
      --enable-bcmath \
      --enable-pcntl \
      --enable-ftp \
      --enable-exif \
      --enable-calendar \
      --enable-sysvmsg \
      --enable-sysvsem \
      --enable-sysvshm \
      --enable-wddx \
      --with-curl \
      --with-mcrypt \
      --with-iconv \
      --with-gmp \
      --with-gd \
      --with-jpeg-dir=/usr/local \
      --with-png-dir=/usr/local \
      --with-zlib-dir=/usr/local \
      --with-freetype-dir=/home/<アカウント名>/local \
      --enable-gd-native-ttf \
      --enable-gd-jis-conv \
      --with-openssl \
      --with-gettext=/usr/local \
      --with-zlib=/usr \
      --with-bz2=/usr/local \
      --with-mysqli \
      --with-pdo-mysql
    
  4. configureを実行
    cd php-7.0.9
    sh ./conf.sh
    
  5. ビルド、テスト、インストールを実行
    make
    make test
    make install
    
    • かなり時間がかかります。(特にテスト。)
    • ここで生成される /home/<アカウント名>/usr/bin/php-cgi が必要なファイルです。

PHP7の設定

  1. PHP7実行ファイルを公開ディレクトリにコピー。どこでも良いのですが、今回はwww/cgi-binにコピーします。
    cp /home/<アカウント名>/usr/bin/php-cgi /home/<アカウント名>/www/cgi-bin/php7.cgi
    
  2. phpスクリプトを設置するディレクトリの.htaccessに以下の記述を追加します。
    Action php7-script /cgi-bin/php7.cgi
    <FilesMatch "\.php$">
    	SetHandler php7-script
    </FilesMatch>
    
  3. php.iniの設置場所は以下になるので、必要に応じて設置します。
    • /home/<アカウント名>/usr/etc/php.ini

PHP7導入の効果

ECO-Wiki (acronia)のCPU負荷はほぼ半分になりました。

  • 4/30にPHP7導入
    php7_resource.png

追記: gzip圧縮するときの注意点

phpの出力をgzip圧縮したい場合は、PHP7実行ファイルを設置したディレクトリ(上記例だとwww/cgi-bin)に、以下の.htaccessを設置します。phpスクリプトと同じディレクトリの.htaccessではうまくいきませんでした。

<FilesMatch "\.cgi$">
	SetOutputFilter DEFLATE

	BrowserMatch ^Mozilla/4\.0[678] no-gzip
	BrowserMatch ^Mozilla/4 gzip-only-text/html
	BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

	AddOutputFilterByType DEFLATE text/html
</FilesMatch>

※text/htmlのみ圧縮。
