2、安装配置eAccelerator
eAccelerator的前身其实是truck-mmcache，因为开发truk-mmcache的人被Zend给招安了，所以开发eAccelerator的人继承了truk-mmcache的一些特性，设计出eAccelerator加速器。安装如下：
$wget http://jaist.dl.sourceforge.net/sourceforge/eaccelerator/eaccelerator-0.9.5.tar.bz2
$tar -jxf eaccelerator-0.9.5.tar.bz2
$cd eaccelerator-0.9.5
$/usr/local/php/bin/phpize
$./configure –enable-eaccelerator=shared –with-php-config=/usr/local/php/bin/php-config
$make
$sudo make install
$sudo mv /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so /usr/local/php/lib/php/extensions/PECL
将下面代码加入php.ini文件中
extension = eaccelerator.so
; eAccelerator
eaccelerator.shm_size = “16”
eaccelerator.cache_dir = “/tmp/eaccelerator”
eaccelerator.enable = “1”
eaccelerator.optimizer = “1”
eaccelerator.check_mtime = “1”
eaccelerator.debug = “0”
eaccelerator.filter = “”
eaccelerator.shm_max = “0”
eaccelerator.shm_ttl = “0”
eaccelerator.prune_period = “0”
eaccelerator.shm_only = “0”
eaccelerator.compress = “1”
eaccelerator.compress_level = “9”
创建缓存目录,重启apache
$sudo mkdir /tmp/eaccelerator
$sudo chmod 777 /tmp/eaccelerator
$sudo /usr/local/apache/apachectl restart
在phpinfo()检查是否安装成功.
