CentOS7 instructions: (restart of nfs not needed, it seems)

yum -y install yum-plugin-versionlock
rpm -q rpcbind # confirm bad version rpcbind-0.2.0-38.el7_3.x86_64
yum -y downgrade rpcbind-0.2.0-38.el7
rpm -q rpcbind # confirm good version rpcbind-0.2.0-38.el7.x86_64
yum versionlock rpcbind
systemctl restart ypserv
systemctl restart ypbind
ypwhich # confirm nis binding
# not needed for el7? systemctl restart nfs # restart rpc.mountd
#yum versionlock delete rpcbind # to undo the lock

K.O.
