librenms 自動更新三不五時要debug好像已經變成日常了

今天打開頁面又是一片空白

先跑一下 /opt/librenms/validate.php

說我沒有安裝mysqlnd 補一下吧

但發現因為我已經安裝 php70w-mysql 所以不能再裝

Processing Conflict: php70w-mysql-7.0.31-1.w7.x86_64 conflicts php70w-mysqlnd
--> Finished Dependency Resolution
Error: php70w-mysql conflicts with php70w-mysqlnd-7.0.31-1.w7.x86_64

google到以下的文章

https://community.librenms.org/t/fail-missing-php-extension-mysqlnd-fix-please-install-mysqlnd/5130/5


yum swap php70w-mysql php70w-mysqlnd

裝好後再跑一次

./validate.php
