　　1、php.ini 配置文件中关于eAcelerator的优化。只使用1M共享内存，删除所有在最后3600秒内无法存取的脚本缓存，用磁盘辅助进行缓存。

[eaccelerator]

zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="1"

eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="3600"

eaccelerator.shm_prune_period="3600"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

eaccelerator.keys = "disk_only"

eaccelerator.sessions = "disk_only"

eaccelerator.content = "disk_only"

　　2、php-fpm.conf 的配置优化

　　修改两项，一是修改以下一行，将启动的php-cgi进程数由原来的128个改为5个：

<val name="max_children">5</val>

　　二是修改以下一行，将TCP模式改为Unix Socket模式：

<val name="listen_address">/tmp/php-cgi.sock</val>

　　1、使用以下参数编译安装的 MySQL 5.1 默认支持4种存储引擎：CSV、MRG_MYISAM、MEMORY、MyISAM，不支持InnoDB存储引擎。由于内存有限，而InnoDB耗费的内存较大，这里推荐使用MyISAM存储引擎。 ./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile

make && make install

　　2、MySQL 5.1 配置文件（my.cnf）优化
