Raspberry Pi文件系统(Raspberry Pi Filesystem)

我有一个问题,我找不到网上任何地方的答案 - 所以我想我会在这里问。 下面是我的Raspberry Pi中目录的代码片段。 我的Pi中安装了16GB SD卡,所有这些目录的总大小只有5GB左右。 当我尝试安装任何内容时,它会显示“Out of Memory”,并且我已经清除了所有日志文件等,以尝试释放空间。

但真正的问题是,为什么它有一个16GB的卡并且我只在它上面安装了apache2和php5时才说完整?

edward@raspberrypi:/ $ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root       3.6G  3.5G     0 100% /
devtmpfs        214M     0  214M   0% /dev
tmpfs           218M     0  218M   0% /dev/shm
tmpfs           218M  4.6M  213M   3% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           218M     0  218M   0% /sys/fs/cgroup
/dev/mmcblk0p1   60M   20M   41M  34% /boot
tmpfs            44M     0   44M   0% /run/user/1000
tmpfs            44M     0   44M   0% /run/user/1001

谢谢你的帮助。


I have a problem which I can't find the answer to anywhere online - so I thought I would ask it here. Below is a code snippet of the directories in my Raspberry Pi. I have a 16GB SD Card installed in my Pi, and the total size of all those directories is only about 5GB. When I try and install anything it says "Out of Memory", and I have already cleared all log files, etc to try and free up space.

But the real question is, why does it say full when it has a 16GB card and I've only installed apache2 and php5 on it?

edward@raspberrypi:/ $ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root       3.6G  3.5G     0 100% /
devtmpfs        214M     0  214M   0% /dev
tmpfs           218M     0  218M   0% /dev/shm
tmpfs           218M  4.6M  213M   3% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           218M     0  218M   0% /sys/fs/cgroup
/dev/mmcblk0p1   60M   20M   41M  34% /boot
tmpfs            44M     0   44M   0% /run/user/1000
tmpfs            44M     0   44M   0% /run/user/1001

Thanks for any help.
