MongoDB가 갑자기 죽어서 당황하게 만든적이 있었다..

실행을 하면 아래와 같이 에러가 출력..

 

Failed to unlink socket file /tmp/mongodb-27017.sock Unknown error

 

열심히 구글링 하여, 해결책을 찾았다

 

 

/tmp/mongodb-27017.sock 파일 여부를 확인 그리고 삭제

[ec2-user@ip-172-17-1-126 /usr/bin]$ 

 

/var/run/mongodb/mongod.pid 삭제

[ec2-user@ip-172-17-1-126 /usr/bin]$ sudo rm -rf /var/run/mongodb/mongod.pid
