Install a new application and run in background

[werneck.costa]

I'm discovering WTWare and it solve some costumers issue. One of my services is to let the costumers to access their applications remotly, by RDP. It's working fine with WTWare.

Now, i'm wondering some questions, that is crucial to our business:
1 - is it possible to install/run some monitoring application (like Zabbix agent)?
2 - is it possible to install/run some configuration manager (like Ansible/puppet)?

Regards,

[akatik]

There is "extra=" parameter to run external applications. But there are very few libraries in WTware, trivial shell and so on, because WTware is small. So something trivial, compiled statically, may run, but not huge monsters. So, answer is no for both questions.

[werneck.costa]

Ok, thanks. Then one chance at least!
Is there some documentation about "extra=" parameter?

[akatik]

Here is an example: viewtopic.php?t=48783

I guess i'm getting close:

| inflating: runme

Until weekend, it will work propertly.

Solved with this steps:

• Raspbian installed on SDCard;

• Zabbix agent compiled directly on Raspbian;

• Brought "zabbix_agentd" binary from compilation (in my case: /usr/src/zabbix/zabbix-3.4.15/src/zabbix_agentd);

• Reinstalled WTWare on SD card;

• Prepared zabbix_agent.zip following @akatik indication, like this:

Code: Select all

#!/bin/sh
chmod +x zabbix_agentd
/zabbix_agentd -f -c zabbix_agentd.conf

• Aditional configuration on "zabbix_agentd.conf":

Code: Select all

AllowRoot=1

• Log results:

Does it work? Remove '-f' from command line, it's not foreground.

[werneck.costa]

Yes, it works!
"-f" is for run it in foreground. I believe it's necessary to WTWare get the logs. Is it?

[aka]

There is local syslog in wtware. Daemon may write logs to syslog if possible. I'm afraid foreground process may read from input, but there is no input.

[werneck.costa]

Ok. What is the syslog file path?
My decision to foreground send was based on "docker way" to show logs. But, in this case, i can send to syslog.

[akatik]

In zabbix_agentd.conf:

Code: Select all

LogType=system

How did you compile it? zabbix_agentd binary from Raspbian requires about twenty libraries that are not in wtware on time where extra= package run.

[werneck.costa]

Ok about config file.
For the firts test, it was compiled from the most simple way:

Code: Select all

./configure --enable-agent
make

The second one, if necessary:

Code: Select all

./configure --enable-agent --without-ssl

The second form obligates the compilation processs to don't put any kind of SSL libs on the way. But the default already is "--without-ssl".

[werneck.costa]

It:

Code: Select all

LogType=system

works fine:

Code: Select all
