2019-08-02 17:09:24 -0500 commented question devstack not working with ubuntu 18.4 LTS

Ideally, if it cant run in 4GB, it should check and abort at the start of the script. Interestingly, I just created an 8GB ubuntu 19 instance. It complained that the OS was not supported (had to use the force option), but it seems to have worked. Now I need to figure out how to use the UI.

2019-08-02 06:58:43 -0500 commented answer new to openstack. If swift uses http and object store, how can you run mysql?

Swfit and mysql are not alternatives, but I understand that openstack does all its storage through swift, which uses http as the transport, not iSCSI or equivalent. I just cant imagine that mysql will perform well if the underlying OS is using http as a storage access protocol.

@Berd thanks for the reply. All the articles I found said 4GB would work. I would assume I see memory errors or crash during install process if not enough memory?

2019-08-02 05:47:48 -0500 asked a question register with google not working

Note, to post here, there is no option to "register" a new account. You have to use an existing google, yahoo or openid.

I dont have yahoo or openid, so I used my gmail account.

However, it never sends the validation email. It is broken.

As google is not working, I could not find how to create an openId - the openid website doesnt have a registraiton.

So I created a yahoo account so that I could use this site. The problem is now I have to have a complete new email just to use this system. It would be much better if there was a way to use an existing email account instead of having to create new ones. I.e. support people who dont have, use or want google, ipendid or yahoo.

At least fix the google option, so uses with existing google account can use openstack forums.

2019-08-02 05:47:48 -0500 asked a question devstack not working with ubuntu 18.4 LTS

I just followed the instructions here: (

on a brand new linode Ubuntu 18.04 LTS (The recommended distro) with 4GB ram, 2 core, 60GB SSD etc.

I first did a sudo apt-get update/upgrade of course.

The article says to do the following, which I did exactly:

sudo useradd -s /bin/bash -d /opt/stack -m stack echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack sudo su - stack git clone cd devstack cp samples/local.conf . (Note, I also tried the min one with just the passwords, same issue) ./

This runs for a long time, then ends with the error output at the end. After the install, there is no dashboard on http://myip/dashboard.

I just wiped the machine, rebuilt it, but this time did a dist-upgrade and reboot before doing the instl using the min conf file as per the documentation. Got more or less the same error:

2019-08-02 05:47:47 -0500 asked a question new to openstack. If swift uses http and object store, how can you run mysql?

Ok, this is a really dumb question. With vmware, you get access to a "drive" which the os sees as if it was a local HD. It has reasonably fast random access to this drive. The actual drive could be local or on a SAN.

We are trying to see if openstack is suitable for our applications. We have been told that openstack is for new generation of scalability aware apps, not typical 3 tier arcitectured apps.

We have seen that swift uses http to communicate with an object store. http would seem to be the last choice in a protocol for an OS and its applications to access the storage.

Given the http limitation, is it feasible to run mysql, or galera cluster, on openstack?
