OpenFlare Agent Uninstaller
|
||||
|
||||
Usage:
|
||||
uninstall-agent.sh [OPTIONS]
|
||||
|
||||
Options:
|
||||
--install-dir DIR Installation directory (default: /opt/openflare-agent)
|
||||
--service-name NAME systemd service name (default: openflare-agent)
|
||||
-h, --help Show this help message
|
||||
|
||||
Behavior:
|
||||
1. Stop the agent service/process and remove the entire installation directory
|
||||
2. Remove the systemd service definition when present
|
||||
3. Check the saved agent config to identify the OpenResty mode
|
||||
4. If Docker mode was used, remove the OpenResty container and try to remove its image
|
||||
5. If local openresty_path mode was used, do not modify the local OpenResty install
|
||||
|
||||
Examples:
|
||||
uninstall-agent.sh
|
||||
uninstall-agent.sh --install-dir /srv/openflare-agent
|
||||
EOF
|
||||
exit 0
