Nginx服务器配置优化方法

今天别人说网站进行了一点优化

　　三、PHP 5.2.6（FastCGI）的配置优化
　　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：

5
　　二是修改以下一行，将TCP模式改为Unix Socket模式：
/tmp/php-cgi.sock

　　四、MySQL 5.1.26 配置优化
　　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
