ossfs allows you to mount Object Storage Service (OSS) buckets as local file systems on Linux. Then, you can manage OSS objects in the same manner as you manage local files.

Runtime environment

We recommend that you run ossfs in the following environments:

  • Linux-based operating systems
    • CentOS 7.0 or later
    • Ubuntu 14.04 or later
  • Fuse 2.8.4 or later

Download URLs

Linux distribution Download
Ubuntu 18.04 (x64) ossfs_1.80.6_ubuntu18.04_amd64.deb
Ubuntu 16.04 (x64) ossfs_1.80.6_ubuntu16.04_amd64.deb
Ubuntu 14.04 (x64) ossfs_1.80.6_ubuntu14.04_amd64.deb
CentOS 8.0 (x64) ossfs_1.80.6_centos8.0_x86_64.rpm
CentOS 7.0 (x64) ossfs_1.80.6_centos7.0_x86_64.rpm

The preceding table provides the download URLs of ossfs installation packages for common operating systems. If your operating system is not included in the table, install ossfs by compiling the source code. For more information about the source code, visit GitHub ossfs.

Notice When you copy the URLs and use them in the wget command to download ossfs, delete ?spm=xxxx from the URLs.


  1. Download the installation package.
    For example, run the following command to download the ossfs installation package for CentOS 7.0 (x64):
    wget http://gosspublic.alicdn.com/ossfs/ossfs_1.80.6_centos7.0_x86_64.rpm
  2. Install ossfs.
    • Ubuntu
      For example, you can run the following command to install ossfs in Ubuntu 16.04 (x64):
      sudo apt-get update
      sudo apt-get install gdebi-core
      sudo gdebi ossfs_1.80.6_ubuntu16.04_amd64.deb
    • CentOS
      For example, you can run the following command to install ossfs in CentOS 7.0 (x64):
      sudo yum install ossfs_1.80.6_centos7.0_x86_64.rpm

      If your client uses Yellowdog Updater, Modified (YUM) to install the Red-hat Package Manager (RPM) package, dependencies may fail to be downloaded when the client node network environment is not suitable. To resolve this issue, you can use YUM to download the dependencies over the normal network to a node that runs the same operating system version, and then copy the dependencies to the required node. For example, ossfs runs based on fuse 2.8.4 or later. You can run the following command to download the latest version of fuse from the YUM source to your local device:

      sudo yum install --downloadonly --downloaddir=./ fuse
      Notice To download other dependencies, replace fuse with the name of the required package.
  3. Configure access information of the account.
    Store the bucket name and the AccessKey pair that can be used to access the bucket in the /etc/passwd-ossfs object. We recommend that you set the object permission to 640.
    echo BucketName:yourAccessKeyId:yourAccessKeySecret > /etc/passwd-ossfs
    chmod 640 /etc/passwd-ossfs
  4. Mount the bucket to the specified directory.
    ossfs BucketName mountfolder -o url=Endpoint
    For example, you can run the following command to mount a bucket named bucket-test to the /tmp/ossfs directory.
    echo bucket-test:LTAIbZcdVCmQ****:MOk8x0y9hxQ31coh7A5e2MZEUz**** > /etc/passwd-ossfs
    chmod 640 /etc/passwd-ossfs
    mkdir /tmp/ossfs
    ossfs bucket-test /tmp/ossfs -o url=http://oss-cn-hangzhou.aliyuncs.com
    Notice If you use an Alibaba Cloud Elastic Compute Service (ECS) instance to provide ossfs services, you can use the internal endpoint of the bucket. In the preceding example, you can set the endpoint of OSS to oss-cn-hangzhou-internal.aliyuncs.com to minimize traffic fees. For more information about the internal endpoints of OSS, see Regions and endpoints.
  5. If you no longer want to mount the bucket, you can run the following command to unmount it:
    fusermount -u /tmp/ossfs
