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