Hi @mushixun I can't seem to reproduce this crash. I used Vagrant to spin up the chef/centos-7.0 box and it seems to work fine (from a clean vagrant up):

sudo yum update
wget https://dl.bintray.com/mitchellh/consul/0.5.2_linux_amd64.zip
sudo yum install unzip
unzip 0.5.2_linux_amd64.zip

[vagrant@localhost ~]$ uname -a
Linux localhost.localdomain 3.10.0-229.11.1.el7.x86_64 #1 SMP Thu Aug 6 01:06:18 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

[vagrant@localhost ~]$ ./consul
usage: consul [--version] [--help] <command> [<args>]

Available commands are:
    agent          Runs a Consul agent

    event          Fire a new event
    exec           Executes a command on Consul nodes
    force-leave    Forces a member of the cluster to enter the "left" state
    info           Provides debugging information for operators
    join           Tell Consul agent to join cluster
    keygen         Generates a new encryption key

[vagrant@localhost ~]$ sha256sum consul

Can you provide more details and maybe confirm the version you are running (I've got the sha256 of the one I downloaded in the dump above). If that doesn't shed light you might want to fire up gdb and/or strace and see if those yield any clues.

[mushixun]

Thanks for you reply，you are right，my question has solved,Thank you!!!

Out of curiosity can you share what it was?

$ uname -a

Ideas? Not supported on 15.10?

Hi @loslosbaby which version of Consul were you running on there?

[loslosbaby]

0.6.1 sorry forgot to include that :)

[loslosbaby]

Weird: I DL'd from releases.hashicorp.com (forever RHC) one one VM, got that working. Spun two more VM's today, used the same URL (from RHC, to get 0.6.1) and I get the SEGV's. Ok, do a sum on the machines:
working$ sum consul
34948 19939
seg1$ sum consul
45513 19882
seg2$ sum consul
45513 19882

I don't have the "working" zip file, I wget'd it into /tmp and its been boot-blasted a day ago+. That's all I know :)

[loslosbaby]

Short and sweet:

$ strace ./consul
execve("./consul", ["./consul"], [/* 21 vars */]) = 0
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} ---
+++ killed by SIGSEGV (core dumped) +++

Hmm - I was able to set up a clean 15.10 box just now and it runs fine - must have gotten a corrupted download somehow. You can use our published shasums to make sure you've got a good binary - https://releases.hashicorp.com/consul/0.6.1/consul_0.6.1_SHA256SUMS.

I just spent half an hour scratching my head over this before I thought to try GDB, turns I'd grabbed the download link to the freebsd version by mistake 😟

Hopefully this saves someone some time in the future.

[murphy7801]

yeah just make sure you grab the right version seems to common fix.
