HTTP ERROR: 503

Problem accessing /admin/. Reason:

Answer 1

Had the same issue. Maybe something went wrong the extraction of the package.

I downloaded this:

wget https://archive.apache.org/dist/activemq/5.15.0/apache-activemq-5.15.0-bin.tar.gz

and extracted it with:

sudo tar -zxvf apache-activemq-5.15.0-bin.tar.gz -C /opt

then it worked for me.

Answer 2

I was getting this same error. It turns out that I had run it as root user originally, then later I stopped it and ran it as a non-root user. Certain data files that had been created and owned by the original root instance were not accessible to the non-root user.

Check the ownership of the files, and change them if necessary to match the user that the broker is running as.

Answer 3

My two cents:

I start with the activemq in Ubuntu Repo, but then later change to binary package from official website.

In my case, the repo version left an /etc/default/activemq config file, which runs activemq with user "activemq". It turns out in previous experiments, I did not kill the old processes running under "activemq" when I start activemq under my own user name. There are two activemq processes running under different user names, and when connecting to admin console, I have a 503.

I delete the /etc/default/activemq file, and kill all activemq processes running under "activemq", then restart activemq with my user name, the 503 is gone.
