关键错误日志

{"t":{"$date":"2021-11-19T14:49:52.359+08:00"},"s":"E",  "c":"NETWORK",  "id":23024,   "ctx":"initandlisten","msg":"Failed to unlink socket file","attr":{"path":"/tmp/mongodb-27017.sock","error":"Operation not permitted"}}

• 从最后几行可以看出关键在这里，/tmp/mongodb-27017.sock对于这个文件的操作权限不足

解决问题

• 这个文件归属mongo操作不了, 删除后又mongo创建后就有操作权限了
