重启以上服务均报错（systemctl restart openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service）
报错如下

解决方法参考https://bugs.launchpad.net/openstack-manuals/+bug/1569878
at the place of the command “chown -R root:swift /var/cache/swift”, we need also execute the command “chmod -R 775 /var/cache/swift”, as when we make dir (as root user) with command “mkdir -p /var/cache/swift”, the access permission of dir /var/cache/swift will be 755(as rwxr-xr-x), which means “swift” user can not write file in this dir. so the exception like below will occur in the log /var/log/messages.”[Errno 13] Permission denied: ‘/var/cache/swift/object.recon'”

if we execute the command “chmod -R 775 /var/cache/swift”, this kind of exception will not occur.

也就是将/var/cache/swift 配置权限为755，即使你看到是755也要使用chmod命令设置一次，然后再重启服务，一切正常了。
