我无法在 Ubuntu LXC 容器中安装 mongodb。
我按照以下说明设置了 Ubuntu 14.10 主机：https://linuxcontainers.org/lxc/getting-started/
lxc-create --version
1.1.0
按照文档，我通过下载模板创建了虚拟机，并选择了 Ubuntu 14.10 amd64 来宾（尽管我在 14.04 amd64 上遇到了相同的行为）：
我开始依恋它
lxc-start -n test0 && lxc-attach -n test0
在我运行的容器内
apt-get update && apt-get install mongodb
安装失败并显示以下输出：

使用 14.04 容器和 10gen 存储库会导致相同的错误：

df -h一些搜索表明该问题可能是由于磁盘空间不足引起的，但根据主机上的说法，可用空间超过15G 。
作为命令运行mongod告诉我它正在寻找 /data/db 路径。创建它将使我能够运行mongod，但运行service mongodb start会返回start: Job failed to start。
我在几个不同的虚拟和物理主机上尝试过，总是出现相同的错误。

不久前，我在使用 Ubuntu 14.04 作为客户操作系统的 lxc 中遇到了类似的问题。我做了一些挖掘，结果发现limit nofile ...mongodb upstart job 中的指令以某种方式导致dpkg --configure对 mongodb-server 包的调用在 mongodb 安装后过程中失败退出。注释该行可以让安装过程继续并成功完成。
