更改Apache默认起始(索引)页面：DirectoryIndex

Apache默认索引页面是index.html,修改成其他文件需要修改httpd.conf文件：

#
# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>

可在Apache根目录建立一个负责跳转的index.php，比如输入IP地址直接跳转到http://ip/myweb/

<?php
    if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
        $uri = 'https://';
    } else {
        $uri = 'http://';
    }
    $uri .= $_SERVER['HTTP_HOST'];
    header('Location: '.$uri.'/myweb/');
    exit;
?>
