claim on step 14 to paste "kernel.shmall = 134217728 kernel.shmmax = 134217728" into /etc/sysctl.conf
however, that needs to be split on to two lines:
kernel.shmall = 134217728
kernel.shmmax = 134217728
i was getting shared memory errors until i tracked down the issue, and it turns out that line in my sysctl.conf was not properly setting shmmax.
