Unable to start uchiwa (sensu dashboard)

Question

Attempt to start uchiwa fails with no error when starting via init.d script and no process.

No output in /var/log/uchiwa.log

Output found in /var/log/uchiwa.err :

/opt/uchiwa/bin/uchiwa: 1: /opt/uchiwa/bin/uchiwa: cannot create ^A: Permission denied
/opt/uchiwa/bin/uchiwa: 1: /opt/uchiwa/bin/uchiwa: ^?ELF^B^A^A^B: not found
/opt/uchiwa/bin/uchiwa: 2: /opt/uchiwa/bin/uchiwa: Syntax error: "(" unexpected
I also ensured permissions in the /etc/sensu directory was correct with:


vagrant@vagrant-ubuntu-trusty-32:~$ ls -la /etc/sensu/
total 44
drwxr-xr-x  8 sensu sensu 4096 Mar 17 10:15 .
drwxr-xr-x 99 root  root  4096 Mar 27 00:55 ..

drwxr-xr-x 4 root root 4096 Mar 17 10:13 ..
drwxr-xr-x 2 root root 4096 Mar 17 10:13 bin
drwxr-xr-x 3 root root 4096 Mar 17 10:13 src

Any idea why this may not be working? Thanks.

UPDATE 1:

There was indeed a permission problem which I resolved by giving the correct permissions which has now resolved:

  /opt/uchiwa/bin/uchiwa: 1: /opt/uchiwa/bin/uchiwa: cannot create ^A: Permission denied

However the following errors still persist:

/opt/uchiwa/bin/uchiwa: 1: /opt/uchiwa/bin/uchiwa: ^?ELF^B^A^A^B: not found
/opt/uchiwa/bin/uchiwa: 2: /opt/uchiwa/bin/uchiwa: Syntax error: "(" unexpected

I have reinstalling the package but it still looks corrupt.

Answer 1

Your Uchiwa directory is owned by root and not the sensu user. You are logged into your Vagrant image as user vagrant . I would give ownership of the /opt/uchiwa directory to sensu with chown . Next run the uchiwa binary as the sensu user.

Answer 2

The problem seems to be the 32 bits binary package contains a 64 bits binary: https://github.com/sensu/uchiwa/issues/457

Installing version 0.13.0-1 seems to work.
