Ubuntu Server server monitoring?

Question

Monitoring

Hello! There is an Ubuntu server, three users have root access. And there are cases when some actions of one user interfere with another. A very funny example: We edited one Apache config weekly for 3 months and the sites did not work for us.
Question. Is there a system for tracking the installation of new software, changes in configs, and indeed actions. To be categorized.

Answer 1

To prevent this from happening - take Ansible or Chef and make a configuration for it. You put the configuration in a repository, for example, GitHub, and builds only through the Building Tool, for example, Jenkins. And that's it, no conflicts. And take away everyone's access from the server, of course

Answer 2

I have a small turnip in Gitlab, which contains Nginx website configs and PHP configs, and a CI job for this turnip, which decomposes all these configs with each commit. And restarts the web server and what else is needed.
Very comfortably.

server-config:
  stage: server-config
  tags:
  - deb96-ovh
  script:
  - sudo cp --verbose --recursive etc /
  - ls -l /etc/nginx/conf.d/
  - sudo nginx -t
  # if commit message has "RESTART" - restart, else - just reload
  - if echo $CI_COMMIT_MESSAGE | grep -iqF restart; then
  -   sudo systemctl restart php7.0-fpm.service
  -   sudo systemctl restart nginx
  - else
  -   sudo systemctl reload php7.0-fpm.service
  -   sudo nginx -s reload
  - fi
