もう半年位悩んでいましたWordPressが物凄く遅い件に関して
今回解決する方法を試してみました。
PHPアクセラレータを導入して高速化を図る。
と言う方法です。
PHPアクセラレータと言っても
何種類かあるようなのでその中のAPCと言うものを利用しPHPの処理を最適化します。
コマンドphpizeを実行して以下の様に表示されれば恐らく
php5-develが入っています。
[root@localhost root]# phpize Cannot find config.m4. Make sure that you run '/usr/bin/phpize' in the top level source directory of the module
こんな風に表示されていない場合はphp5-develが入っていない可能性があります。
インストールしましょう。
#apt-get install php5-devel
APC
ここからダウンロードするAPCのURLを確認します。
今回はAPC-3.0.19.tgzを使用しました。
コマンドwgetでファイルを/rootへダウンロードします。
[root@localhost root]# wget http://pecl.php.net/get/APC-3.0.19.tgz
--14:15:28-- http://pecl.php.net/get/APC-3.0.19.tgz
=> `APC-3.0.19.tgz'
pecl.php.net をDNSに問いあわせています... 216.92.131.66
pecl.php.net|216.92.131.66|:80 に接続しています... 接続しました。
HTTP による接続要求を送信しました、応答を待っています... 200 OK

/rootにダウンロードされた事を確認し解凍します。

解凍したAPCのディレクトリに移動し
コマンドphpizeを実行し
コンパイルしてインストールします。

----------------------------------------------------------------------
Libraries have been installed in:
/root/APC-3.0.19/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test'.
[root@localhost APC-3.0.19]# make install
Installing shared extensions: /usr/lib/php5/
/usr/lib/php5/内にapc.soが作成されている事を確認。
[root@localhost APC-3.0.19]# ls /usr/lib/php5/ apc.so* build/ mysql.so* pdo.so* pdo_sqlite.so* bin/ mcrypt.so* mysqli.so* pdo_mysql.so*
/rootへ戻りphp.iniを編集します。
[root@localhost root]# vi /etc/php5/php.ini 下記を最下部に追記 extension=apc.so
Apache2を再起動
[root@localhost root]# /etc/rc.d/init.d/apache2 restart httpdを停止中: [ OK ] httpdを起動中: [ OK ] [root@localhost root]#
これでPHPで書かれたプログラム(WordPress等)を高速処理できます。
