高速化の必要性に迫られて入れてみた
環境はGoogle Compute Engine上のVMインスタンス(CentOS7,Apache2.4,PHP5.4)です。
EPELリポジトリの追加
$ sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
必要な物を入れる
$ sudo yum install -y cpp gcc-c++ cmake git psmisc {binutils,boost,jemalloc}-devel {ImageMagick,sqlite,tbb,bzip2,openldap,readline,elfutils-libelf,gmp,lz4,pcre}-devel lib{xslt,event,yaml,vpx,png,zip,icu,mcrypt,memcached,cap,dwarf}-devel {unixODBC,expat,mariadb}-devel lib{edit,curl,xml2,xslt}-devel glog-devel oniguruma-devel ocaml gperf enca libjpeg-turbo-devel openssl-devel ccache make --enablerepo=epel
MariaDBを起動
$ sudo systemctl mariadb start
ソースをcloneしてくる
サイズがでかいので割と時間かかります
$ cd /tmp
$ git clone https://github.com/facebook/hhvm -b master hhvm --recursive
$ cd ./hhvm/
権限を変更
そのままだと、ユーザ権限でUNIXドメインソケットで動作させるのに不都合があるので、1箇所変更する(760→766)
$ vim hphp/runtime/server/fastcgi/fastcgi-server.cpp
if (m_socketConfig.bindAddress.getFamily() == AF_UNIX) {
auto path = m_socketConfig.bindAddress.getPath();
chmod(path.c_str(), 0766); /* ※←ここ */
}
こちらを参考にさせていただきました
ビルドする
PATHは好きな所に置き換えて下さい（今回はこちらに倣って/opt/hhvm/）
あと僕の環境では、makeの途中でext_zend_compatからエラーでコケたので、-DENABLE_ZEND_COMPAT=ONを付けてます
$ sudo cmake -DCMAKE_INSTALL_PREFIX:PATH=/opt/hhvm -DCMAKE_C_FLAGS="-march=native" -DCMAKE_CXX_FLAGS="-march=native" -DENABLE_ZEND_COMPAT=ON -DLIBMAGICKWAND_INCLUDE_DIRS="/usr/include/ImageMagick" -DLIBMAGICKCORE_LIBRARIES="/usr/lib64/libMagickCore.so" -DLIBMAGICKWAND_LIBRARIES="/usr/lib64/libMagickWand.so" .
$ sudo make -j$(($(nproc)))
$ sudo make install
Imagickからエラー [2015-10-20 追記]
公式のサンプルと同様に、echo $imagick_objとしていた箇所からエラー。
Catchable fatal error: Object of class Imagick could not be converted to string
無理矢理、echo strval($imagick_obj)としてみる
Fatal error: Resource did not provide a name
ダメぽい。
結果的に、Imagick::getImagesBlobを使うようにして解決
echo $imagick_obj->getImagesBlob();
Zend Engineの時は出なかったエラーなんですが…ちなPHPは5.4です
計測してみる
手元のサイト(CakePHP)で150回(50回*3)ほどアクセスした結果、以下のようになりました（使用ツールはSiege）
