Can't get MistServer to start. Ubuntu Xenial

[John Byrne]

Hi!

I'm trying to get MistServer working on a dedicated server. I'm running Ubuntu Xenial on an ARM7 processor and used the following install command:

curl -o - https://releases.mistserver.org/is/mistserver_armv7V2.13.tar.gz 2>/dev/null | sh

When I start the service, I then check the status with the "service mistserver status" command and here's the result:

root@vidserv:/# service mistserver start

root@vidserv:/# service mistserver status

● mistserver.service - MistServer

   Loaded: loaded (/etc/systemd/system/mistserver.service; enabled; vendor preset: enabled)

May 01 11:09:19 vidserv systemd[1]: mistserver.service: Start request repeated too quickly.

May 01 11:09:19 vidserv systemd[1]: Failed to start MistServer.

I thought that the system may be having problems creating /etc/mistserver.conf so I created an empty mistserver.conf file but I still get the same result.

Any ideas on how to make this work?

Thanks in advance for your help.

Hello John,

Could you try running "MistController" on a terminal by hand, and see what that does?

I'm guessing likely there is some kind of library or kernel incompatibility with your distro and what we use to compile our ARMv7 builds, running it by hand should show a more helpful error message.

Thanks for your response Jaron,

I SSH'd in to my server and typed "MistController" at the prompt. Here is the response:

root@vidserv:~# MistController

-bash: /usr/bin/MistController: No such file or directory

Pretty weird, right? The file MistController is certainly present in /usr/bin because I can see it in a directory listing.

Hey John,

That's weird yes, I can't say I've seen it before at the very least. I've been mostly using this version on my raspberry Pi V3, which is a ARMv7 Processor rev 4 (v7l), but otherwise pretty much the same. I can only think of one thing that will definitely solve this, which is compile your own MistServer. Luckily you're using the open source version, so that should be an option.

Our binaries are available here: https://github.com/DDVTECH/mistserver

Either clone the repository or download the source code. Cloning the repository would make updating easier, but you do have to set up and use git.

To build MistServer correctly you will need:

cmake and a c++ compiler

The most common c++ compilers we see and test with at the moment are gcc and clang, so I would recommend one of those if you haven't installed one, but any should work.

and run:

cmake .

make install

Once done you should have the binaries again, the only difference is that these should definitely work. Obviously if you run into any problems during the build let us know, we'll try and help you where we can.
