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 host. Repeat this on the client and on each of the servers. 

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

Certificate Authorities

Compile all the certificates in one place and concatenate them into two files. glusterfs.ca and glusterfs-client.ca. 

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

Copy glusterfs.ca to /etc/ssl on all servers. Copy glusterfs-client.ca to /etc/ssl on the client.
