大佬教程收集整理的这篇文章主要介绍了权限 – 由于“[Errno 13] Permission denied”,无法将文件上传到Raspberry Pi 3上的OpenStack Swift 2.14.0，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
$swift stat

$swift post s3perf
$swift list -A http://10.0.0.253:8080/auth/v1.0 -U test:tester -K tesTing
bucket
s3perf
这些是关于文件storage1.error中的桶创建的(正)消息.
$tail -f /var/log/swift/storage1.error ...

但任何上传文件的尝试都会导致错误消息[Errno 13]权限被拒绝.

proxy.error文件还包含错误消息ERROR 500 Expect：100-conTinue From Object Server.
@H_282_7@may 18 20:55:44 raspBerrypi proxy-server: ERROR 500 Expect: 100-conTinue From Object Server 127.0.0.1:6010/d1 (txn: txfbf08bffde6d4657a72a5- 00591dee30) (client_ip: 10.0.0.220)
我已经将Swift作为用户pi启动并将这些文件夹分配给该用户：
$sudo chown pi:pi /etc/swift $sudo chown -R pi:pi /mnt/sdb1/* $sudo chown -R pi:pi /var/cache/swift $sudo chown -R pi:pi /var/run/swift
$mount | grep sdb1 /srv/swift-disk on /mnt/sdb1 type xfs (rw,noatime,nodiratime,attr2,nobarrier,inode64,logbufs=8,noquota) $ls -ld /mnt/sdb1/1/ drwxr-xr-x 3 pi pi 17 May 12 13:14 /mnt/sdb1/1/
我部署了Swift this way.
我想知道为什么创建存储桶(conrainers)有效但由于权限被拒绝而导致文件上传失败.

当我创建一个存储桶时,Swift服务会创建一个像这样的文件夹：
/mnt/sdb1/1/node/d1/containers/122/9d5/7a23d9409f11da3062432c6faa75f9d5/
此文件夹包含一个db-file,如7a23d9409f11da3062432c6faa75f9d5.db.我认为这是正确的行为.
但是当我尝试在存储桶中上传文件时,Swift只创建一个像这样的空文件夹.
/mnt/sdb1/1/node/d1/objects/139/eca/8b17958f984943fc97b6b937061d2eca
我可以通过touch或echo作为用户pi在这些空文件夹中创建文件,但由于未知原因,Swift不会将文件存储在这些文件夹中.
更新6
为了进一步研究这个问题,我根据SAIO – Swift All In One指令在Ubuntu 14.04 LTS的VMware ESXi虚拟机中安装了Swift,在RaspBerry Pi 3上安装了另一次在Raspbian内部.结果是,在Ubuntu 14.04 VM内部,Swift工作得很好,但是当在RasBerry Pi上运行时,上传文件不起作用.

问题仍然没有解决,但我现在在RaspBerry Pi上有一个有效的Swift服务.我安装了(相当过时的)Swift 2.2.0版,它随Raspbian一起提供,效果很好.我做的步骤在here中解释.
