DD-WRT：什么固件和什么网络服务器适合我的 8MB 闪存？

Question

这个与 DD-WRT 无关，但类似：

我在具有 8 MiB 闪存的设备上使用了 OpenWRT，并使用附带的 uhttpd 服务器作为 Web 服务器。

OpenWRT 的优势在于它的 squashfs 映像更小并且它的根目录位于 JFFS2 中并且可以编辑。

配置部分也很简单。有趣的文件是 /etc/config/uhttpd

# Server configuration

        # HTTP listen addresses, multiple allowed

我使用配置 uhttpd 次要部分添加了一个新站点。只需复制配置 uhttpd 主要部分，编辑它并以新名称粘贴回去即可。在我的例子中，另一个站点仅监听 IPv6 连接，其根目录位于 /mnt/www。

在我的 TP-LINK TL-WR1043ND 上，默认安装（包括 uhttpd）占用了 4 MiB 多一点的空间，因此网站至少应该有 3.5 MiB 的可用空间。
