檢查roundcude 數據庫錯誤問題

請檢查roundcude錯誤日誌文件 ▼

/usr/local/cwpsrv/var/services/roundcube/logs/errors

如果你的錯誤看起來像這樣 ▼

[17-May-2021 20:18:11 +0000]: <gv4343g> DB Error: SQLSTATE[HY000] [1045] Access denied for user 'roundcube'@'localhost' (using password: YES) in /usr/local/cwpsrv/var/services/roundcube/program/lib/Roundcube/rcube_db.php on line 173 (GET /roundcube/)
[17-May-2021 20:18:11 +0000]: <gv4343g> DB Error: SQLSTATE[HY000] [1045] Access denied for user 'roundcube'@'localhost' (using password: YES) (GET /roundcube/)

檢查roundcube 配置文件

檢查roundcube 配置文件中設置的密碼  /usr/local/cwpsrv/var/services/roundcube/config/config.inc.php

grep db_dsnw /usr/local/cwpsrv/var/services/roundcube/config/config.inc.php

輸出將像這樣 ▼

$config['db_dsnw'] = 'mysqli://roundcube:42Etn3fd7skc@localhost/roundcube';

• 這表示的密碼是 42Etn3fd7skc

現在讓我們在MySQL的中設置相同的值 ▼

mysql -e "SET PASSWORD FOR 'roundcube'@'localhost' = PASSWORD('42Etn3fd7skc');"
mysql -e "FLUSH PRIVILEGES;"

檢查roundcube是否有效？

現在，再次檢查roundcube是否有效？

如果出現此錯誤 ▼

[17-May-2021 20:29:09 +0000]: <gv91fd30g> DB Error: [1146] Table 'roundcube.session' doesn't exist (SQL Query: SELECT `vars`, `ip`, `changed`, now() AS ts FROM `session` WHERE `sess_id` = 'gv93bfdsfdffdfdj3') in /usr/local/cwpsrv/var/services/roundcube/program/lib/Roundcube/rcube_db.php on line 539 (GET /roundcube/)

運行此命令 ▼

mysql -u root 'roundcube' < /usr/local/cwpsrv/var/services/roundcube/SQL/mysql.initial.sql

就是這樣，享受你的 roundcude （圓角立方體）。
