首先安装一些基本的组件
yum -y install autoconf automake
去eAccelerator官方下载最新版的源码包：eaccelerator- 0.9.6.1.zip并解压
http://bart.eaccelerator.net/source/0.9.6.1/eaccelerator-0.9.6.1.zip
unzip eaccelerator-0.9.6.1.zip
cd eaccelerator-0.9.6.1
export PHP_PREFIX="/usr/local"
$PHP_PREFIX/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
make
make install
mkdir /tmp/eaccelerator
chmod 777 /tmp/eaccelerator
然后编辑PHP.INI，并放置到Zend之前
[eAccelerator]
zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.log_file = "/var/log/eaccelerator_log"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
重启apache服务即可在phpinfo()中看到
service httpd restart
