Nextcloud 重建 oc_filecache

首先先備份原來的 Table:

use nextcloud;
RENAME TABLE oc_filecache TO oc_filecache_bak;
CREATE TABLE oc_filecache SELECT * FROM oc_filecache_bak LIMIT 0

再使用 occ 指令重建 oc_filecache:

sudo -u www-data ./occ files:scan --all

這時候可能會遇到 mysql 超時:

Exception during scan: An exception occurred while executing 'DELETE FROM `oc_filecache` WHERE `fileid` = ?' with params [null]:

SQLSTATE[08S01]: Communication link failure: 1053 Server shutdown in progress


去修改 /etc/my.cnf.d/server.cnf ,在 [mysqld] 下面新增:


重啟 MariaDB:

systemctl restart mariadb

再重建一次,檔案越多,需要更長的 timeout 時間,不然的話會跑不完阿(J1900 QQ)
