GlusterFS Encryption
Servers
Once all this works we will continue by adding TLS encryption to the setup.
Keys
On each of the Glusterfs servers run.
mkdir /etc/ssl/glusterfs cd /etc/ssl/glusterfs openssl genrsa -out glusterfs.key 2048
Certificates
Now sign a certificate using that key.
root@gluster01:/etc/ssl/glusterfs# openssl req -new -x509 -key glusterfs.key -subj "/CN=gluster01" -out glusterfs.pem root@gluster02:/etc/ssl/glusterfs# openssl req -new -x509 -key glusterfs.key -subj "/CN=gluster02" -out glusterfs.pem root@gluster03:/etc/ssl/glusterfs# openssl req -new -x509 -key glusterfs.key -subj "/CN=gluster03" -out glusterfs.pem root@gluster04:/etc/ssl/glusterfs# openssl req -new -x509 -key glusterfs.key -subj "/CN=gluster04" -out glusterfs.pem
