在php5.2.5上安裝了eaccelerator-0.9.5.3
CODE: export PHP_PREFIX="/opt/php"
$PHP_PREFIX/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
make && make install
然后把eaccelerator.so拷貝到/opt/php/lib/php/extensions/目錄下
在php.ini里面加上以下參數
CODE: extension_dir = "/opt/php/lib/php/extensions/"
extension="eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="512"
eaccelerator.shm_ttl="1024"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
另外APC-3.0.19的也裝了測試，效果和eaccelerator差不多
CODE: export PHP_PREFIX="/opt/php"
$PHP_PREFIX/bin/phpize
./configure --enable-apc --enable-apc-mmap --with-apxs=/opt/apache/bin/apxs --with-php-config=/opt/php/bin/php-config
make && make install
然后把apc.so拷貝到/opt/php/lib/php/extensions/目錄下
CODE: extension_dir="/opt/php/lib/php/extensions/"
extension="apc.so"
apc.enabled="1"
apc.shm_size="128"
apc.mmap_file_mask=/tmp/apc.XXXXXX
tmp目錄并沒有/tmp/apc.的文件，奇怪了
我運行的效果只提升了一點性能，跟網上一些評測說提升3倍以上的性能相差太多了
