init.d 下的 Apache 守护进程文件为空

打开文件夹/var/cache/apt/archives并找到 apache deb 文件 ( apache2-common...)。

使用以下命令提取文件：

dpkg -x <your_deb> /tmp/apache2

用你的空/etc/init.d/apache2替换/tmp/apache2/etc/init.d/apache2

如果找不到该文件，那么您可以在此处下载 deb 文件。

对于这里或这里的旧版本。选择最适合的版本。

或者将此用于您的 Ubuntu 9.10，采取from apache2-common_2.0.55-4ubuntu2.13_amd64.deb：
