php 5.6を7.0にアップデートしたので次はOpcacheとAPCuを導入します｡
APCがAPCuとZend OPcacheに取って代わられたワケ
http://qiita.com/nntsugu@github/items/63099b829befb57859d7
APCとZend OPcache/APCuの関係
APCが機能として持っている
opecode cache機能とdata cache機能を
PHP 5.5+では
opecode cache : Zend OPcache
data cache : APCu
で提供するようになりました。
※上記サイトから引用しました｡
今回はAPCuも導入します｡
- OPcacheのインストール
- OPcache設定ファイル作成
- 10-opcache.iniの編集
- APCuのインストール
- APCu設定ファイル作成
- 40-apcu.iniの編集
- OPcacheとAPCuの確認
- Apache再起動

# yum info php70-php-opcache 読み込んだプラグイン:fastestmirror 利用可能なパッケージ 名前 : php70-php-opcache アーキテクチャー : x86_64 バージョン : 7.0.8 リリース : 1.el7.remi 容量 : 118 k リポジトリー : remi 要約 : The Zend OPcache URL : http://www.php.net/ ライセンス : PHP 説明 : The Zend OPcache provides faster PHP execution through opcode caching : optimization. It improves PHP performance by storing precompiled scri : bytecode in the shared memory. This eliminates the stages of reading : the disk and compiling it on future access. In addition, it applies a : bytecode optimization patterns that make code execution faster. # yum -y install php70-php-opcache (snip) Running transaction インストール中 : php70-runtime-1.0-5.el7.remi.x86_64 インストール中 : php70-php-json-7.0.8-1.el7.remi.x86_64 インストール中 : php70-php-common-7.0.8-1.el7.remi.x86_64 インストール中 : php70-php-opcache-7.0.8-1.el7.remi.x86_64 検証中 : php70-php-opcache-7.0.8-1.el7.remi.x86_64 検証中 : php70-runtime-1.0-5.el7.remi.x86_64 検証中 : php70-php-json-7.0.8-1.el7.remi.x86_64 検証中 : php70-php-common-7.0.8-1.el7.remi.x86_64 インストール: php70-php-opcache.x86_64 0:7.0.8-1.el7.remi 依存性関連をインストールしました: php70-php-common.x86_64 0:7.0.8-1.el7.remi php70-php-json.x86_64 0:7.0.8-1.el7. php70-runtime.x86_64 0:1.0-5.el7.remi 完了しました! |
OPcacheの設定ファイルが/etc/opt/remi/php70/php.d/10-opcache.iniにあるのでこれを利用します｡
