sonar 在異常關機後沒法啓動

啓動sonar的時候一直啓動不了,報錯以下:

WrapperSimpleApp: Encountered an error running main: java.nio.file.AccessDeniedException: /usr/local/sonarqube/temp/conf/es/jvm.options

問題定位： java.nio.file.AccessDeniedException: /usr/local/sonarqube/temp/conf/es/jvm.options 解決方案： 各類嘗試無果，原來一直是好好的， 後來看到網上有一篇其餘問題的，刪除了temp後解決。 刪除重啓sonar後，temp文件會從新生成。 因而，備份temp,刪除temp.重啓，問題解決
