錯誤：[050]：無法獲取文件“/tmp/pgbackrest/demo-archive.lock”的鎖定：權限被拒絕

Question

我一直在嘗試從源代碼（ https://access.crunchydata.com/documentation/pgbackrest/2.00/pdf/backrest.pdf ）在 linux(ubuntu) 上的 postgres 中增量加載數據，而我正在嘗試創建一個節我收到以下錯誤。

由於我是 Linux 平台的新手，所以花了 2 天以上的時間，我無法解決它！

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]

出現這種情況的原因是什么以及如何解決？

我遇到了同樣的問題，只需刪除臨時文件夾及其文件即可解決

sudo rm -r pgbackrest/

它對我有用。 另一種可能的解決方案是刪除臨時文件夾和節並重新創建節。
