Overview

Note The amzon-efs-utils package comes preinstalled on Amazon Linux and Amazon Linux 2 Amazon Machine Images (AMIs).
Note By default, when using the Amazon EFS mount helper with Transport Layer Security (TLS), the mount helper enforces certificate hostname checking. The Amazon EFS mount helper uses the stunnel program for its TLS functionality. Some versions of Linux don't include a version of stunnel that supports these TLS features by default. When using one of those Linux versions, mounting an Amazon EFS file system using TLS fails. When you've installed the amazon-efs-utils package, to upgrade your system's version of stunnel, see . You can use AWS Systems Manager to manage Amazon EFS clients and automate the tasks required to install or update the amazon-efs-utils package on your EC2 instances. For more information, see . For issues with encryption, see .

Manually installing the Amazon EFS client

Note If you're using AWS Direct Connect, you can find installation instructions in .

Upgrading stunnel

Note The default CentOS shell is csh, which has different syntax than the bash shell. The following code first invokes bash, then moves /bin/stunnel to /root.
