Second, the problem is solved
1, reason: Errcode: 28 - No space left on device: insufficient disk space. MySQL server installation, lack of disk space.
2, to solve: expand disk space; delete junk files and so on.
3, Linux Step Reference:
- df -lh: Check disk space distribution
- cd xx: enter the directory filled space
- du -sh *: Check the file size of each directory
- Find junk files take up space
- rm xx: delete junk files. ( Deleted before you repeatedly confirmed, the data can not be recovered !! priceless! )
