What consequence deleting idb file will have on my mysql database? I tried to check what is consumming my Disk Space on Centos 7, I found these 2 database file: 


  /var/lib/mysql/pub/vues.ibd: 8.1G 
  /var/lib/mysql/pub/log.ibd: 8.6G


I would like to delete them. pub is the name of my database.
And log and vues are  tables.
That would be most unwise. Never fiddle with MySQL files directly.

If you want to delete those tables use SQL:

DROP TABLE pub.vues, pub.log
