Modify the Linux VPS host mounted hard disk folder directory configuration tutorial

This morning a netizen bought a bird cloud host product, because the system installed the default automatically mounted directory is the data directory, and this friend needs to install WDCP panel, in theory can also be in the background of the Panel designated directory, but he must follow the official directory www mount. So help him to deal with it can directly modify the Mount directory to resolve the existing directory replacement process.

First, the theoretical step method

In theory, there are a lot of ways to do this online, we just need to create a directory to be mounted, and then uninstall the existing mounted directory, and then go back to the new directory to mount the problem can be solved.

1. New WWW directory

The code is as follows	Copy Code
Mkdir/www

2. Download the catalog that has been mounted

The code is as follows	Copy Code
Umount/data

3. Mount to new catalogue

The code is as follows	Copy Code
Mount/dev/sdb1/www

4, modify the configuration file

The code is as follows	Copy Code
Echo '/dev/sdb1/www ext3 defaults 0 0 ' >>/etc/fstab

In theory such an operation can complete the replacement directory. But the old left side in the operation of the time there are some problems, in the umount when there are "Umount:/data:device is busy." In some cases useful info about processes this use the device was found by lsof (8) or fuser (1), the error cannot be unloaded.

Second, solve the problem

Here because the program is occupied, we only need to check the ID and then delete it so that the procedure can be done.

1, Fuser/data

The code is as follows	Copy Code
/data:947c

We can see that there really is a program occupied.

2, view the process

The code is as follows	Copy Code
[Root@niaoyun data]# ps-ef |grep 94c Root 1435 947 0 22:47 pts/0 00:00:00 grep 94c [Root@niaoyun data]# Ps-ef |grep 94 Root 944 2 0 22:30? 00:00:00 [flush-253:0] Root 945 868 0 22:33? 00:00:00 sshd:root@pts/0 Root 947 945 0 22:34 pts/0 00:00:00-bash Root 1468 947 0 22:48 pts/0 00:00:00 ps-ef Root 1469 947 0 22:48 pts/0 00:00:00 grep 94

3. Delete Occupation

The code is as follows	Copy Code
Kill-9 945

Finally, we can continue the operation to complete the umount of the replacement catalog.
