In certain situations, such as needing to enable a feature or troubleshoot an issue, you may need to reinstall the Netdata Agent on your node. Run the one-line installer script with the `--reinstall` parameter to reinstall the Netdata Agent. This will preserve any in `netdata.conf` or other files, and will keep the same install type that was used for the original install. If you used any [optional parameters](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/kickstart.md#optional-parameters-to-alter-your-installation) during initial installation, you need to pass them to the script again during reinstallation. If you cannot remember which options you used, read the contents of the `.environment` file and look for a `REINSTALL_OPTIONS` line. This line contains a list of optional parameters. ```bash wget -O /tmp/netdata-kickstart.sh https://get.netdata.cloud/kickstart.sh && sh /tmp/netdata-kickstart.sh --reinstall ``` Run the one-line installer script with the `--reinstall-clean` parameter to perform a clean reinstall of the Netdata Agent. This will wipe all existing configuration and historical data, but can be useful sometimes for getting a badly broken installation working again. Unlike the regular `--reinstall` parameter, this may use a different install type than the original install used. If you used any [optional parameters](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/kickstart.md#optional-parameters-to-alter-your-installation) during initial installation, you need to pass them to the script again during reinstallation. If you cannot remember which options you used, read the contents of the `.environment` file and look for a `REINSTALL_OPTIONS` line. This line contains a list of optional parameters. ```bash wget -O /tmp/netdata-kickstart.sh https://get.netdata.cloud/kickstart.sh && sh /tmp/netdata-kickstart.sh --reinstall-clean ``` The clean reinstall procedure outlined above can also be used to manually change the install type for an existing installation. Without any extra parameters, it will automatically pick the preferred installation type for your system, even if that has changed since the original install. If you want to force use of a specific install type, you can use the `--native-only`, `--static-only`, or `--build-only` parameter to control which install type gets used, just like with a new install. When using the `--reinstall-clean` option to change the install type, you will need to manually preserve any configuration or historical data you want to keep. The following directories may need to be preserved: `/etc/netdata` (`/opt/netdata/etc/netdata` for static installs): For agent configuration. `/var/lib/netdata` (`/opt/netdata/var/lib/netdata` for static installs): For claiming configuration. `/var/cache/netdata` (`/opt/netdata/var/cache/netdata` for static installs): For historical data. When copying these directories back after the reinstall, you may need to update file ownership by running `chown -R netdata:netdata` on them. If you still experience problems with your Netdata Agent installation after following one of these processes, the next best route is to and then try a fresh installation using the [one-line installer](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/kickstart.md).
