Hi

i have an problem regarding to change the default apache

path from "/var/www/html" to new add hardisk, the new add

hardisk http path i,m going to use is "/media/af3558aa-6786-43fa-b026-2c42df622795/http", i modify

the "/etc/httpd/conf/httpd.conf" and change

the path to "DocumentRoot /media/af3558aa-6786-43fa-b026-2c

42df622795/http/" and then to restart the httpd service, and

below error appeared "DocumentRoot must be a directory", is

it workable to change path to add new hardisk ? and this

linux rhel 6 64bit is a VM machine, the new add hardisk is

an additional vm storage added from esxi 5, any body have

idea ? thx

piaakit

Please show

I would safe me the hassle and just mount the new partition at the old DocumentRoot /var/www/html afte copying the files over to it. Then restart apache.

i,m new in linux, can you tell me the step to mount the new partition at the document root /var/www/html ?

Try the following
Just have in mind that all the files that are under /var/www/html are masked by the new mount and can't be accesed until the new mount is umounted again.

if i mount it like this, it will use the new add hardisk's storage ?

Yes. Read up on the mount command. And maybe filestructure or filesystem under linux in generell.
The mount command takes two arguments. One is the device in your case given with the UUID and the path inside the filesystem where the new device should be accessible at. Just do a df -h before the mount and after the mount and you will see the difference.

How come that I can not direct chagr the document root path from original to new add hardisk, is it because of partition issue ?

You sure could use the new path for the docroot. There are just many ways to do things.
My guess is that the path your using as the new DocumenRoot isn't there yet. Did you create it?
Please give the output of
In case the dir is not there yet do a
Just another thing to remark is that after everything works you should enter the /media/af3558aa-6786-43fa-b026-2c42df622795/ mount into your /etc/fstab file

The destnation path is already exist, It is a new add hardisk from vm, and I will show u the output when I get home

below is the output

although i mount the drive but still showing this message

"DocumentRoot must be a directory"

Hm, tough one. So the directory exists but apache is still complaining. Last shot of me would be a typo.

Okay lets try this. Change the DocumentRoot back to its original value (/var/www/http it was?), restart apache. This is too make sure that we have a generel sane configuration.
After that make extra to get path right. cd into the /media/uuid/http directory and use the command pwd to print the working directory. Copy that and paste it into the apache configuration as the value for DocumentRoot.
Or maybe you can mount the new disk under a simpler directory. Something like /media/new_disk. This way you can nearly rule out typos.

Hi

mount the new disk under a simpler directory (can you show me how to do that ?) ,& how to get rid of the uuid display in \media\uuid of a new drive ?

keith

Okay some explanation for names a disk partition can be addressed through.
You can use the name of the partition like it is under /dev. In your case this should be /dev/sdb1 if I read your fdisk -l output correct. (Using dev names may lead to errors cause the bios might rearrange the order harddrives are named during reboots).
Or can use the uuid of the partition. Use the blkid tool to get it. Or use tune2fs -l /dev/devicename
Or one can use a label when creating the filesystem.

Now to mount (You did have a look at man mount, didn't you )
mount needs a device and a path. The opposite command is umount and it only needs one of the options you used when mounting a device. So you could unmount the drive either by specifying the path where its mounted or use the device name. For ease use
After unmounting the drive you can mount it like this
and the new disk will be available under /media/new_disk/. AS long as the directory exists.

HOw to get rid of the /media/uuid thing should be some options for udev. But I'm not sure about it. Did the disk got automounted after adding the new disk through VM?
