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
openssl req -new -x509 -key gluster01.key -subj "/CN=gluster01" -out gluster01.pem

Certificate authorities

compile all the certificates in one place and concatename 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

# create the server keys
openssl genrsa -out gluster01.key 2048
openssl genrsa -out gluster02.key 2048
openssl genrsa -out gluster03.key 2048
openssl genrsa -out gluster04.key 2048
# sign the server certificates
openssl req -new -x509 -key gluster01.key -subj "/CN=gluster01" -out gluster01.pem
openssl req -new -x509 -key gluster02.key -subj "/CN=gluster02" -out gluster02.pem
openssl req -new -x509 -key gluster03.key -subj "/CN=gluster03" -out gluster03.pem
openssl req -new -x509 -key gluster04.key -subj "/CN=gluster04" -out gluster04.pem
# create the client keys
openssl genrsa -out glusterclient01.key 2048
# sign the client certificates
openssl req -new -x509 -key glusterclient01.key -subj "/CN=glusterclient01" -out glusterclient01.pem
# server certificates authorities
cat gluster01.pem gluster02.pem gluster03.pem gluster04.pem glusterclient01.pem > glusterfs.ca
# client certificates authorities
cat gluster01.pem gluster02.pem gluster03.pem gluster04.pem > glusterfs-client.ca
