Gitlab daemon crashing. Omnibus installation (Ubuntu 14.04)

Hi,

I followed the instructions for Gitlab pages, but it seems that the daemon is crashing all the time. The only information I could find regarding the crash is:

 2016-02-24_02:11:23.54988 2016/02/24 02:11:23 fork/exec .daemon.e4da6694574fdf55ab129e87b7a30d98: no such file or directory

 2016-02-24_02:11:24.67915 Start failed (0x7ffffe514a00,0xc8200af380)

My gitlab.rb configuration looks like this, but port 80 is dead:

pages_external_url 'http://tyto.cf'
nginx['listen_addresses'] = ['10.100.43.8']
pages_nginx['enable'] = false
gitlab_pages['external_http'] = '10.100.163.125:80'

I was trying just with

pages_external_url 'http://tyto.cf'

and I was getting a 502

Is there anything I should enable to debug this?

This appears to be a problem:

fork/exec .daemon.e4da6694574fdf55ab129e87b7a30d98: no such file or directory

Do you have some special permissions on /var/opt/gitlab/gitlab-rails/shared/pages (like noexec?)

This is what I found

 drwxr-x--- 4 git gitlab-www  5 Feb 24 18:29 pages
 drwxr-x--- 2 git gitlab-www  2 Feb 19 09:46 pages.1455875814

I tried setting every under pages to 755 but still throwing the same error over and over again.

Could you try to build and run this: https://gitlab.com/gitlab-org/gitlab-pages/merge_requests/3?

I'm running the production omnibus gitlab. It's going to take me a while to do this.

A couple of updates. I updated gitlab to 8.5.1. Also did a small change to the configuration, it's what I'm currently using.

  pages_external_url 'http://tyto.cf'
  nginx['listen_addresses'] = ['10.100.43.8']

Still the same error.

@juanpin Did you try the above MR?

I'm running into a similar error attempting to get the test suite to daemonize, so hopefully I can track this down.

Got it. The error being returned looks like this:

root@60a4ae992a79:/go/src/gitlab.com/gitlab-org/gitlab-pages# GO15VENDOREXPERIMENT=1 go build -o gitlab-pages-linux . && ./gitlab-pages-linux -listen-http :9200 -daemon-uid 0 -daemon-gid 65534 -pages-root `pwd`/shared/pages

However, it's not that file itself that's missing, it's various dynamic libraries that the file depends on when built without CGO_ENABLED=0

$ CGO_ENABLED=0 go build -o gitlab-pages .
$ ldd gitlab-pages
	not a dynamic executable

vs.

$ CGO_ENABLED=1 go build -o gitlab-pages .
$ ldd gitlab-pages-linux
	linux-vdso.so.1 (0x00007fff9bff8000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb0ecdb6000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb0eca0b000)
	/lib64/ld-linux-x86-64.so.2 (0x0000561f076e0000)

If you have the latter type of binary, you can replicate this error by calling chroot directly:

$ ls gitlab-pages
gitlab-pages
$ chroot . gitlab-pages
chroot: failed to run command 'gitlab-pages': No such file or directory

In short, the daemonized mode only works if the binary is compiled with CGO_ENABLED=0 - which is set in the Makefile, but people using go build directly (as I was earlier today) would be surprised by this.

I'll add a short passage to the README for now, and commit the fixes that allow the error to show.
