使用相同的 AWS EFS 共享多个目录

Question

I have create a file system EFS and mount on a EC2 instance on /var/www/html/media. I would like to use the same EFS Filesystem to mount another directory /var/www/html/var.

Is that possible?

I would to do:

fs-296e0282.efs.us-west-2.amazonaws.com:/media   /var/www/html/media   nfs4    defaults

fs-296e0282.efs.us-west-2.amazonaws.com:/var   /var/www/html/var   nfs4    defaults

But it seems no possible.

Answer 1

It is possible to mount two different directories under file mount system. Initially in order to access your efs just mount a EFS root under your instance using the command

Sudo mount -t efs fs-id:/ /home/efs

Then create subdirectories under the /home/efs folder for example let's have two subdirectories under /home/efs namely media and var

Now you can mount two directories in /var/www/html/media and /var/www/html/var by adding the below in fstab file which will be under /etc/

fs-id:/media /var/www/html/media efs defaults,_netdev 0 0

fs-id:/var /var/www/html/var efs defaults,_netdev 0 0

And reboot your instance. Whatever changes in /var/www/html/media will gets reflected in fs-id:/media folder also the same applies for var folder also hope this helps.

Answer 2

Your EFS id: fs-357f69c8

You want to mount in a EC2 Machine of following folders

• /efs
• /var/www/html/data
• /var/www/html/api/upload
• /var/www/html/uploadetfiles

So, first, create the folders

• sudo mkdir /efs
• sudo mkdir /var/www/html/data
• sudo mkdir /var/www/html/api/upload
• sudo mkdir /var/www/html/uploadetfiles

For mount in EC2 command will be

• sudo mount -t efs -o tls fs-357f69c8:/ /efs
• sudo mount -t efs -o tls fs-357f69c8:/ /var/www/html/data
• sudo mount -t efs -o tls fs-357f69c8:/ /var/www/html/api/upload
• sudo mount -t efs -o tls fs-357f69c8:/ /var/www/html/uploadetfiles

NB: Your machine should have efs-utils installed

To build and install an RPM:

• sudo yum -y install git rpm-build make
• sudo git clone https://github.com/aws/efs-utils
• cd efs-utils
• sudo make rpm
• sudo yum -y install build/amazon-efs-utils*rpm

To build and install a Debian package:

• sudo apt-get update
• sudo apt-get -y install git binutils
• sudo git clone https://github.com/aws/efs-utils
• cd efs-utils
• sudo ./build-deb.sh
• sudo apt-get -y install ./build/amazon-efs-utils*deb

Hope this will works
