linux主机的用户一般都是apache环境，使用 .htaccess 文件来设置，如果你网站根目录已经存在这个文件，那就复制一下代码添加进去。

RewriteEngine on
#安全设置 禁止以下目录运行指定php脚本
RewriteCond % !^$
RewriteRule a/(.*).(php)$ – [F]
RewriteRule data/(.*).(php)$ – [F]
RewriteRule templets/(.*).(php|htm)$ – [F]
RewriteRule uploads/(.*).(php)$ – [F]

<rule name="Block data" stopProcessing="true">
  <match url="^data/(.*).php$" />
    <conditions logicalGrouping="MatchAny">
     <add input="{USER_AGENT}" pattern="data" />
     <add input="{REMOTE_ADDR}" pattern="" />
   </conditions>
  <action type="AbortRequest" />
</rule>
<rule name="Block templets" stopProcessing="true">
  <match url="^templets/(.*).php$" />
     <conditions logicalGrouping="MatchAny">
      <add input="{USER_AGENT}" pattern="templets" />
      <add input="{REMOTE_ADDR}" pattern="" />
    </conditions>
  <action type="AbortRequest" />
</rule>
<rule name="Block SomeRobot" stopProcessing="true">
   <match url="^uploads/(.*).php$" />
      <conditions logicalGrouping="MatchAny">
         <add input="{USER_AGENT}" pattern="SomeRobot" />
         <add input="{REMOTE_ADDR}" pattern="" />
      </conditions>
    <action type="AbortRequest" />
</rule>

Nginx下禁止指定目录运行PHP脚本

location ~* /(a|data|templets|uploads)/(.*).(php)$ {
return 403;
}

测试有没有生效，可以随便创建一个PHP文件传到uploads文件夹下，执行：域名/uploads/测试文件.php  如果不能打开说明生效。
