這個(gè)項(xiàng)目的app端可以連接到數(shù)據(jù)庫(登錄注冊(cè)),但是后臺(tái)連接不到數(shù)據(jù)庫(無法登錄) 求大神解答!

這個(gè)配置文件是沒有問題的,我本地也在用這個(gè)配置文件,本地和線上是一個(gè)數(shù)據(jù)庫.
數(shù)據(jù)庫是mysql,安裝在liunx上,項(xiàng)目也在同一臺(tái)服務(wù)器上面.
現(xiàn)在這個(gè)服務(wù)器上的其他項(xiàng)目連接這個(gè)數(shù)據(jù)庫沒有問題,只有這個(gè)項(xiàng)目的后臺(tái)連接不上數(shù)據(jù)庫!
