How to Resolve the 'Failed to Connect to Database' Error

• 상황

  • 기존 설치된 Go 개발 환경에서 CB-Spider 서버 가동시(start.sh 실행) 다음과 같은 오류를 만났을 때

    ```
    panic: Failed to Connect to Database
    goroutine 1 [running]:
    [github.com/cloud-barista/cb-spider/cloud-info-manager/connection-config-info-manager.init.0()](http://github.com/cloud-barista/cb-spider/cloud-info-manager/connection-config-info-manager.init.0())
            /home/ubuntu/workspace/cb-spider-master/cloud-info-manager/connection-config-info-manager/ConnectionConfigInfoManager.go:41 +0xde
    ```
    

• 원인
  • Spider가 활용하는 Gorm은 Go build 시 CGO On 필요

• 설정

   * 확인
   $ go env |grep CGO_ENABLED
   CGO_ENABLED='0'
  
   * On 설정
   $ go env -w CGO_ENABLED=1
  
   * 확인
   $ go env |grep CGO_ENABLED
   CGO_ENABLED='1'
  

• CB-Spider rebuild 필요
