web gui fails, upgrade-antman fails

First, I am a linux NOOB!!!!

Second, I just installed Edgelinux on a server.

Installation went well, thanks to the videos.

After the last reboot (after the installs and updates) I can logon to the console or via SSH no problem.

IP address is

Launch a web browser on same network go to err connection refused

go to I get a Welcome to centos

Port scanner shows only  80, 22 and 6880 are open on the server - no 3000

go to gives me a bad gateway error

netstat -a|grep 3000 gives a blank response

Upgrade-antman fails on docker - too many restarts of the service - See Below

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
* Installing wetty docker image...
Redirecting to /bin/systemctl start docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
* Could not start docker, aborting. [ !! ]
* Installing files failed, aborting. [ !! ]
Error while upgrading antman
Redirecting to /bin/systemctl start antman.service

Please help, but remember, if you provide instructions, I am a total linux know nothing, so please be gentle and detailed.

I really appreciate the help


Hi Authuric:

Let's see if antMan is listening on port 3000:

ss -tpln | grep 3000

If it's running, you can stop it:

systemctl stop firewalld

If you'd like to still use firewalld, you can enable port 3000 through firewalld:

firewall-cmd --permanent --add-port=3000/tcp

Here are instructions for getting Docker service back up:

This procedure will get docker service working again but WILL WIPE OUT existing Docker Containers:

Stop and wipe all current docker files:
service docker stop
rm -rf /var/lib/docker/*

Try to mount:
zfs mount antlets/_docker

If the command above fails saying antlets/_docker doesn't exist, run:
zfs create antlets/_docker -o mountpoint=/var/lib/docker

check that /etc/docker/daemon.json contains
{ "storage-driver": "zfs" }

Start docker:
service docker start

Check docker using zfs
docker info | grep zfs

You can get the default docker images running the upgrade-antman command:

Make sure the docker service starts after a reboot
eL 2.0.0: systemctl enable docker
eL 0.x.x: rc-update add docker default
