[BUG] Wazuh indexer error when used with service on rhel-based systems

[fcaffieri]

Describe the bug

After analyzing the following issue https://github.com/wazuh/wazuh-jenkins/issues/6821, a problem was detected with the sysv service in the wazuh indexer packages for 4.9.0

Evidence:

OS: RedHat9
Wazuh Version: 4.9.0

[root@stack-redhat9 vagrant]# uname -a
Linux stack-redhat9 5.14.0-362.8.1.el9_3.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Oct 3 11:12:36 EDT 2023 x86_64 x86_64 x86_64 GNU/Linux
[root@stack-redhat9 vagrant]# /var/ossec/bin/wazuh-control info
WAZUH_VERSION="v4.9.0"
WAZUH_REVISION="40903"
WAZUH_TYPE="server"
[root@stack-redhat9 vagrant]#

Testing with systemctl:

[root@stack-redhat9 vagrant]# systemctl status wazuh-indexer
● wazuh-indexer.service - wazuh-indexer
 Loaded: loaded (/usr/lib/systemd/system/wazuh-indexer.service; enabled; preset: disabled)
 Active: active (running) since Wed 2024-07-31 20:43:55 UTC; 30min ago

Tests with service:

[root@stack-redhat9 vagrant]# service wazuh-indexer status
The wazuh-indexer startup script does not exist or it is not executable, tried: /usr/share/wazuh-indexer/bin/wazuh-indexer
[root@stack-redhat9 vagrant]#

Then if we perform the same test but with a 4.8.1 package we obtain the following:

OS: RedHat9
WAzuh Version: 4.8.1

[root@stack-redhat9-2 vagrant]# uname -a
Linux stack-redhat9-2 5.14.0-362.8.1.el9_3.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Oct 3 11:12:36 EDT 2023 x86_64 x86_64 x86_64 GNU/Linux
[root@stack-redhat9-2 vagrant]# /var/ossec/bin/wazuh-control info
WAZUH_VERSION="v4.8.1"
WAZUH_REVISION="40817"
WAZUH_TYPE="server"
[root@stack-redhat9-2 vagrant]#

Testing with systemctl:

[root@stack-redhat9-2 vagrant]# systemctl status wazuh-indexer
● wazuh-indexer.service – Wazuh-indexer
 Loaded: loaded (/usr/lib/systemd/system/wazuh-indexer.service; enabled; preset: disabled)
 Active: active (running) since Wed 2024-07-31 21:22:40 UTC; 4min 14s ago

Tests with service:

[root@stack-redhat9-2 vagrant]# service wazuh-indexer status
Redirecting to /bin/systemctl status wazuh-indexer.service
● wazuh-indexer.service – Wazuh-indexer
 Loaded: loaded (/usr/lib/systemd/system/wazuh-indexer.service; enabled; preset: disabled)
 Active: active (running) since Wed 2024-07-31 21:22:40 UTC; 4min 25s ago

To Reproduce
Steps to reproduce the behavior:

1. Install Wazuh components version 4.9.0 into RedHat9 OS.
2. Execute the command service wazuh-indexer status
3. It will be displayed that the command does not work

Expected behavior
It is possible to execute the start, stop and status actions with both systemd and sysv

Screenshots

It seems we are including a /etc/init.d/wazuh-indexer file in rpm packages for 4.9.0 that wasn't previously present. If we remove the file, the issue goes away:

[root@rhel9 ~]# service wazuh-indexer status
The wazuh-indexer startup script does not exists or it is not executable, tried: 

[root@rhel9 ~]# rm /etc/init.d/wazuh-indexer
rm: remove regular file '/etc/init.d/wazuh-indexer'? y

[root@rhel9 ~]# service wazuh-indexer status

I'm working on removing the file from rpm packages.

Removing a service file that OpenSearch uses looks like a risky move for me. We need to better understand this problem. I'm blocking the issue.
