説明

Hi,

I was trying to install logstash on Amazon Linux 2. After installing it, I couldn't start/enable the service. After some debugging, I noticed the systemd configuration installed by /usr/share/logstash/bin/system-install. However, I do my tests and development mostly on AWS t3.nano and this binary is memory intensive and won't work on low memory.

The exit code could have been checked in here https://github.com/elastic/logstash/blob/master/pkg/centos/after-install.sh#L8 which could tell yum something has gone wrong. I could raise a PR for that, but, in that case, it could be impossible to install the package successfully. Or system-install can be changed by a/set of bash script(s) but I can't see the whole picture by myself that I could contribute with a PR.

  • Version: 7.10.2
  • Operating System: Amazon Linux 2
  • Config File (if you have sensitive info, please remove it):
  • Sample Data:
  • Steps to Reproduce:
    • Install logstash on a low memory VM, Computer etc

調査方針
Investigate the `/usr/share/logstash/bin/system install` script and the `pkg/centos/after install.sh` file linked in the issue. The after install.sh script at line 8 does not check the exit code of system install, which could fail on low memory systems. Consider adding exit code checking or modifying system install to handle low memory gracefully. Also, explore if there are existing issues or PRs related to logstash on low memory instances.
