#6359

Hi team, this PR replaces the /Library/Ossec/bin/wazuh-control command usage with launchctl to start and stop the Wazuh agent service.

Test

Starting with a stopped agent:

sh-3.2# /Library/Ossec/bin/wazuh-control status
wazuh-modulesd not running...
wazuh-logcollector not running...
wazuh-syscheckd not running...
wazuh-agentd not running...
wazuh-execd not running...

The service is launched:

sh-3.2# sudo launchctl load /Library/LaunchDaemons/com.wazuh.agent.plist

The service status is shown currently in both launchctl command and /Library/Ossec/bin/wazuh-control:

sh-3.2# /Library/Ossec/bin/wazuh-control status
cat: /Library/Ossec/var/start-script-lock/pid: No such file or directory
wazuh-modulesd is running...
wazuh-logcollector is running...
wazuh-syscheckd is running...
wazuh-agentd is running...
wazuh-execd is running...

sh-3.2# launchctl print system/com.wazuh.agent
com.wazuh.agent = {
	active count = 1
	copy count = 0
	one shot = 0
	path = /Library/LaunchDaemons/com.wazuh.agent.plist
	state = running

	program = /Library/StartupItems/WAZUH/Wazuh-launcher
	arguments = {
		/Library/StartupItems/WAZUH/Wazuh-launcher
	}

	default environment = {
		PATH => /usr/bin:/bin:/usr/sbin:/sbin
	}

	environment = {
		XPC_SERVICE_NAME => com.wazuh.agent
	}

	domain = com.apple.xpc.launchd.domain.system
	minimum runtime = 10
	exit timeout = 5
	runs = 1
	successive crashes = 0
	pid = 4517
	immediate reason = speculative
	forks = 3
	execs = 2
	initialized = 1
	trampolined = 1
	started suspended = 0
	proxy started suspended = 0
	last exit code = (never exited)

	event triggers = {
	}

	endpoints = {
	}

	dynamic endpoints = {
	}

	pid-local endpoints = {
	}

	instance-specific endpoints = {
	}

	event channels = {
	}

	sockets = {
	}

	instances = {
	}

	spawn type = daemon
	spawn role = (null)
	jetsam priority = 3
	jetsam memory limit (active) = (unlimited)
	jetsam memory limit (inactive) = (unlimited)
	jetsamproperties category = daemon
	submitted job. ignore execute allowed
	jetsam thread limit = 32
	cpumon = default

	properties = {
		partial import = 0
		launchd bundle = 0
		xpc bundle = 0
		keepalive = 0
		runatload = 1
		low priority i/o = 0
		low priority background i/o = 0
		dataless file mode = 0
		legacy timer behavior = 0
		exception handler = 0
		multiple instances = 0
		supports transactions = 0
		supports pressured exit = 0
		supports idle hysteresis = 0
		enter kdp before kill = 0
		wait for debugger = 0
		app = 0
		system app = 0
		creates session = 0
		inetd-compatible = 0
		inetd listener = 0
		abandon process group = 0
		one-shot = 0
		event monitor = 0
		penalty box = 0
		pended non-demand spawn = 0
		role account = 0
		launch only once = 0
		system support = 0
		app-like = 0
		inferred program = 1
		joins gui session = 0
		joins host session = 0
		parameterized sandbox = 1
		resolve program = 0
		abandon coalition = 0
		high bits aslr = 0
		extension = 0
		nano allocator = 0
		no initgroups = 0
		start on fs mount = 0
		endpoints initialized = 1
		is copy = 0
		disallow all lookups = 0
		system service = 0
		protected by submitter = 0
	}
}

Then the service is stopped:

sh-3.2# sudo launchctl unload /Library/LaunchDaemons/com.wazuh.agent.plist
/Library/LaunchDaemons/com.wazuh.agent.plist: Operation now in progress

And checking its status, it's not running, as expected:

sh-3.2# /Library/Ossec/bin/wazuh-control status
wazuh-modulesd not running...
wazuh-logcollector not running...
wazuh-syscheckd not running...
wazuh-agentd not running...
wazuh-execd not running...

Checks

Docs building

• Compiles without warnings.

Code formatting and web optimization

• Uses three spaces indentation.
• Adds or updates meta descriptions accordingly.
• Updates the redirects.js script if necessary (check this guide).

Writing style

• Uses present tense, active voice, and semi-formal registry.
• Uses short, simple sentences.
• Uses bold for user interface elements, italics for key terms or emphasis, and code font for Bash commands, file names, REST paths, and code.

I'm just mentioning that we're using # prompt with sudo here.
