/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?
答案1
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。
或者为您的 Ubuntu 9.10 拍摄此照片from apache2-common_2.0.55-4ubuntu2.13_amd64.deb
