安裝 eaccelerator

wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.zip
unzip eaccelerator-0.9.5.3.zip
cd eaccelerator-0.9.5.3
/usr/local/php5-fastcgi/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php5-fastcgi/bin/php-config
make
make install

再在 php.ini 加上

extension="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.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"

再來就是增加目錄

mkdir /tmp/eaccelerator
chmod 0777 /tmp/eaccelerator
chown xxx:xxx /tmp/eaccelerator
