apacheの最近のブログ記事

httpd.confを弄ってみた。

FileETag None
ExpiresActive On
ExpiresDefault "access plus 4 weeks"
SetOutputFilter DEFLATE
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
DeflateCompressionLevel 9
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/rdf+xml application/xml application/x-javascript

mod_deflateとmod_expiresとHTTPヘッダへのETag付与。
CPUもそれほど喰わず、いい感じ。

ちなみに、mod_deflateによる圧縮状況は、ログとかHTTPヘッダでも確認できますが、こんな感じで確認できるサイトが分かりやすくて宜しいかと。

圧縮転送に対応していないＵＲＬを入力すると、"もしgzip転送したら...."なデータを表示してくれます。

Cache容量を食い潰していたので。増量。

# vi /etc/php.d/eaccelerator.ini

; The amount of shared memory (in megabytes) that eAccelerator will use.
; "0" means OS default. Default value is "0".
;eaccelerator.shm_size = "0"
eaccelerator.shm_size = "64"

# /etc/init.d/httpd restart

今、phpinfo()を眺めてて気づいたんだけど、Zend Optimizer入ってないでやんの。orz
もう眠いので、コレは明日のお楽しみで。

15分前に、Zend optimizer未導入であることに気付く。

明日はどんな風が吹くか分からないので、今やることにする。

というわけで、Zend Technologiesから持ってきましたよ、ZendOptimizer-3.3.0a-linux-glibc21-i386.tar.gz。

$ gunzip -dc ZendOptimizer-3.3.0a-linux-glibc21-i386.tar.gz | tar xvf -
$ cd ZendOptimizer-3.3.0a-linux-glibc21-i386
# ./install.sh

はい。終了。
先ほどのポストから20分経過。

......errorでつ。

PHP Fatal error: [Zend Optimizer] Zend Optimizer 3.3.0 is incompatible with eAccelerator 0.9.5.2 in Unknown on line 0

あぁ、eAccelerator設定の後ろにZend Optimizerを書けばいいのね。

# vi /etc/php.d/eaccelerator.ini

Ctrl+G,oして

[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.0
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.0
zend_optimizer.version=3.3.0a
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

を追記

OK。

早速ApacheBenchを。
