Unable to start sensu-backend on fresh install using stable release

[treydock]

Expected Behavior

I'd expect systemctl start sensu-backend to actually start the daemon.

Current Behavior

Dec 06 22:03:55 sensu-backend.example.com sensu-backend[30949]: {"component":"ee-backend","level":"error","msg":"error starting etcd: mkdir /var/lib/sensu/etcd: permission denied","
Dec 06 22:03:55 sensu-backend.example.com sensu-backend[30949]: panic: runtime error: invalid memory address or nil pointer dereference
Dec 06 22:03:55 sensu-backend.example.com sensu-backend[30949]: [signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x11bd68e]

If I create /var/lib/sensu/etcd owned by sensu the daemon starts just fine.

Possible Solution

Add /var/lib/sensu/etcd/ back into packages.

Steps to Reproduce (for bugs)

1. Start with fresh install of any supported OS - examples on CentOS 7
2. yum install sensu-go-agent sensu-go-backend sensu-go-cli
3. systemctl start sensu-backend
4. systemctl status sensu-backend - daemon failed
5. journalctl -xe - see errors

Context

I am trying to get Puppet module updated to support stable and part of our tests is on fresh installs for supported platforms and now those tests are all failing.

Your Environment

• Sensu version used (sensuctl, sensu-backend, and/or sensu-agent): 5.0.0
• Installation method (packages, binaries, docker etc.): RPM and DEB
• Operating System and version (e.g. Ubuntu 14.04): CentOS 7, Ubuntu 16.04 so far

[treydock]

Another possible solution would be to install /var/lib/sensu as being owned by sensu user.

Looks like beta set /var/lib/sensu to have ownership sensu:sensu and now stable sets it root:root and this breaks fresh install ability to create /var/lib/sensu/etcd.

[treydock]

It looks like new default state-dir changed and must now be defined in backend.yml as seems default doesn't match example config.

[amdprophet]

@treydock the default state-dir should be /var/lib/sensu/sensu-backend. We missed updating the default in the binary (see #2546) but packages were updated correctly. Please see /usr/share/doc/sensu-go-backend-5.0.1/backend.yml.example and /usr/share/doc/sensu-go-agent-5.0.1/agent.yml.example inside of either the deb or rpm packages for the updated example configs which should represent the defaults.
