[Linaro-validation] How to deploy the LAVA system

[zxmjiang]

Hi Neil and all,
Currently from LAVA deployment of:
Now we installed the lava-server-2017.2 and lava-dispatcher-2017.2 on a server, from the system can use:
lava lava-dashboard-tool lava-dispatcher-slave lava-mount-masterfs lava-slave
lava-daemon lava-dispatch lava-master lava-publisher lava-tool
My question is:
1. How to use those command under linux to let it works as the picture shows ?
2. We try to use $lava-master, the log shows following error, seems the lava-server can't run as a sub-process, since from the git lava-server package there is no lava-server executive command installed, can you help it ?
File "/usr/local/bin/lava-master", line 4, in <module>
__import__('pkg_resources').run_script('lava-server==2017.2', 'lava-master')
File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 738, in run_script

Except for 'lava-tool' you need not use any other command on a regular
basis. Most of them are services (in other words daemons) rather than
regular commands.

lava-server is not a command. As noted above it is a service.

In order to start lava-server, use the following command:

# service lava-server start

What is the operating system in which this setup runs? As of today we
only support Debian as seen from here -
https://staging.validation.linaro.org/static/docs/v2/installing_on_debian.html#installing-on-a-debian-based-distribution

Thank You.

Hi Neil and all,
Now we installed the lava-server-2017.2 and lava-dispatcher-2017.2 on
a server, from the system can use: lava
lava-dashboard-tool lava-dispatcher-slave lava-mount-masterfs
lava-slave lava-daemon lava-dispatch
lava-master lava-publisher lava-tool
"/usr/local/lib/python2.7/site-packages/lava_server-2017.2-py2.7.egg/EGG-INFO/scripts/lava-master",

/usr/local/ is *not* supported, it does *not* work. It has been at
least three years since LAVA ceased support for any and all deployments
directly from git or deployments using pypi or virtual environments or
any method of installation *except* on a Debian system, Jessie or later.

Note: As in the documentation, Ubuntu is explicitly *not* supported
since Trusty and there are no updates of LAVA for Trusty due to
problems with versions of packages within Trusty.

You must create a Debian Jessie virtual machine to run LAVA if you are
not running Debian. Ubuntu is not the same.
