转载:nginx配置文件的location标签执行顺序和反向代理配置
location / {
}
location ~ .*\.(gif)$ {
}
对于这样的配置文件,开始我一直没弄清楚他的顺序,比如/gif.gif这个文件,我开始以为location /{} 这里是匹配的,所以开始要执行里面的东西,然后到location ~ .*\(gif)$ {}又能匹配,然后又执行里面的代码,其实这种思路是错的。
nginx执行顺序其实很简单,正则表达式优先,然后才是普通的。相当于就是SQL的 ORDER BY 正则表达式的LOCATION,先后顺序.
location /{虽然在前面,不过location ~.*\.gif是正则,所以他匹配 location ~.*\.gif.
下面贴一个我常用的nginx反向代理配置。(前端缓存图片,js和flash文件)
