I am using ubuntu 16.04.5 and I wanna install devstack. the installation was finished and everything seems working fine. but when I want to start using openstack commands, it feeds back error. As the experience from google, I tried export no_proxy=127.0.0.1 to close the http proxy, but still not work. i would really appreciate if someone can help me to narrow down the root cause! Thanks in advance.

I have also shutdown the ufw and iptables.

I tried below, does it mean the keystone component was not installed successfully? stack@ubuntu-devstack:~/devstack$ which nova /usr/local/bin/nova stack@ubuntu-devstack:~/devstack$ which keystone stack@ubuntu-devstack:~/devstack$ which neutron /usr/local/bin/neutron stack@ubuntu-devstack:~/devstack

Is Keystone running at all? “Connection refused” indicates it’s not listening at 127.0.0.1:5000.

What OpenStack release is this? What are the server’s specs? Can you share your local.conf? Why don’t you use openrc to set the shell environment?
