S3FS is a fuse filesystem you can use to mount s3 bucket on your local filesystem.

In this guide I will show how to quickly install s3fs and use it in /etc/fstab to mount it on your local server.

Tested On

OS: Amazon Linux AMI release 2012.03
S3FS version: 1.61
Hardware: Virtual Machine (AWS AMI)

Install S3FS

  • Install prerequisite packages
yum install kernel kernel-devel libxml2-devel curl-devel pkgconfig fuse openssl-devel subversion fuse-devel automake -y
  • Download and Install S3FS
cd /usr/local/src
svn checkout s3fs-read-only
cd s3fs-read-only
./ && ./configure && make && make install
  • Configure your s3 credentials in s3fs configuration file. You need to have an account configured with access keys and with write access rights to s3.
vi /etc/passwd-s3fs
  • If you have different users for different buckets you can use the following syntax
  • Change permission to s3fs configuration file
chmod 640 /etc/passwd-s3fs
  • Try to mount your buacket
mkdir /mnt/s3
s3fs mybucket /mnt/s3
df -h /mnt/s3
echo test1 > /mnt/s3/test
  • Remove test file and unmount your bucket from a temporary location
rm -f /mnt/s3/test
umount /mnt/s3
  • Configure /etc/fstab to mount your bucket at startup
vi /etc/fstab
s3fs#mybucket /data fuse allow_other 0 0
  • mount your new bucket
mount /data
