GlusterFS Encryption

The default GlusterFS setup does not encrypt its communication. Use the method below enable encryption.

Keys and Certificates

Make an encryption key and make sure to set the CN to match the name of the client/server. Repeat this on all the servers and the client.

Servers

cd /etc/ssl
openssl genrsa -out glusterfs.key 2048
openssl req -new -x509 -key glusterfs.key -subj "/CN=gluster01" -out glusterfs.pem

Client

cd /etc/ssl
openssl genrsa -out glusterfs.key 2048
openssl req -new -x509 -key glusterfs.key -subj "/CN=glusterclient01" -out glusterfs.pem

Certificate Authorities

Servers

Compile all the certificates in one place and concatenate them into /etc/ssl/glusterfs.ca. Notice that this will also include the certificates from the client.

cat gluster01.pem gluster02.pem gluster03.pem gluster04.pem glusterclient01.pem > glusterfs.ca

Client

Copy the certificate authority to all the servers and place it in /etc/ssl/glusterfs.ca

Activate Encryption

When this file exists the glusterfs server will use the new certificates

touch /var/lib/glusterd/secure-access

Enable Encryption

On one of the servers encryption is enabled

gluster volume set www client.ssl on
gluster volume set www server.ssl on

Allow Only Specific Hosts

We allow only access from known hosts

gluster volume set www auth.ssl-allow 'gluster01,gluster02,gluster03,gluster04,glusterclient01'
