init.d 下的 Apache 守护进程文件为空

init.d 下的 Apache 守护进程文件为空

/etc/init.d/apache2几天前我的 Apache2 守护进程不知怎么的变空了,我注意到它在过去几天影响了日志轮换过程。

我的apache版本是Apache/2.2.12 (Ubuntu)

我怎样才能以安全的方式再次恢复该脚本而无需重新安装 apache,并保持当前配置 + 所有虚拟主机不变?

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

/etc/init.d/apache2用以下替换你的空/tmp/apache2/etc/init.d/apache2

如果找不到该文件,那么你可以下载一个 deb 文件这里

对于旧版本这里或者这里. 选择最适合的版本。
