CentOS 6.5 automatically mounts the hard disk upon startup

CentOS 6.5 automatically mounts the hard disk upon startup

The construction of enterprise-level application systems usually stores systems and data separately, and creates raid. The newly installed CentOS 6.5 requires mounting a data disk, and the system can start to automatically mount the data disk.

1. Manually mount the disk

View the disk partition information and run the fdisk command.

Check that/dev/sdb1 is not mounted. Next, create a mount point (create a mount directory) and run the mount command to mount the data disk.

A [root@www.bkjia.com] # mkdir/tsp

[Root @ tsp-rls-webservice tsp] # mount/dev/sdb1/tsp

2. Start the system and automatically mount the data disk
