错误：[050]：无法获取文件‘/tmp/pgbackrest/demo- acquire ve.lock’的锁:权限被拒绝

Question

我一直试图在postgres on linux(ubuntu)中从源(https://access.crunchydata.com/documentation/pgbackrest/2.00/pdf/backrest.pdf)增量加载数据，而当我试图创建一个节时，我得到了以下错误。

因为我是Linux平台的新手，已经花了两天多的时间了，我无法解决这个问题！

sudo -u postgres pgbackrest --stanza=demo --log-level-console=info stanza-create
2019-10-03 16:16:22.730 P00   INFO: stanza-create command begin 2.16: --log-level-console=info --pg1-path=/var/lib/postgresql/11/demo --repo1-path=/var/lib/pgbackrest --stanza=demo

ERROR: [050]: unable to acquire lock on file '/tmp/pgbackrest/demo-archive.lock': Permission denied
       HINT: does the user running pgBackRest have permissions on the '/tmp/pgbackrest/demo-archive.lock' file?
2019-10-03 16:16:22.730 P00   INFO: stanza-create command end: aborted with exception [050]

出现这种情况的原因是什么?如何解决它？

Answer 1

我遇到了同样的问题，只需删除临时文件夹及其文件即可解决

sudo rm -r pgbackrest/

这对我很管用。另一种可能的解决方案是删除temp文件夹并节，然后重新创建节。
