<p>浏览器输入: test.example.com<br>将会访问E:/Servers/nginx-1.10.3/html/index.html<br>结论: 如果没有指定root, 那么root的值为nginx根目录下/html/</p>

<p>浏览器输入: test.example.com<br>将会访问E:/index.html<br>原因如下: 首先将由location a处理到, 然后从html目录下寻找index.html, 找到后, 内部重定向<br>相当于访问test.example.com/index.html, 于是被location b规则处理。最后就访问了E:/index.html。</p>

<p>浏览器输入: test.example.com<br>出现403 Forbidden<br>原因如下: 首先将由location a处理到, 然后从E:/Servers/nginx-1.10.3目录下寻找index.html<br>由于该目录下没有index.html文件, 于是nginx会打开这个目录, 但是autoindex off禁止了目录访问,所以出现了该现象,如果autoindex on, 将会访问这个目录。</p>
<h3 id="总结"><a href="#总结" class="headerlink" title="总结"></a>总结</h3><p><strong>1. root的默认目录是nginx安装目录的html文件夹</strong><br><strong>2. 如果根据规则查找到该文件, 并且没有别的规则来处理test.example.com/index.html的话, 将直接访问该文件, 如果有别的规则处理, 则交由该规则处理。如果查找不到该文件, 则会打开root指定的目录</strong></p>
