Nginx优化配置详解

#指定缓存最大数目以及缓存的时间

open_file_cache_valid

#在open_file_cache中指定检测正确信息的间隔时间

open_file_cache_min_uses

#定义了open_file_cache中指令参数不活动时间期间里最小的文件数

open_file_cache_errors

#指定了当搜索一个文件时是否缓存错误信息

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$

#指定缓存文件的类型

{

expires 3650d;

#指定缓存时间

}

location ~ .*\.(js|css)?$

{

expires 3d;

}

expires有个缺点就是如果更新WEB数据后，用户没有清理缓存，会看到旧的数据，因此建议将时间设置短一点
