This will preserve +any [user configuration](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md) 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://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh --reinstall +``` + +### Performing a clean 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.

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. + +## Troubleshooting + +If you still experience problems with your Netdata Agent installation after following one of these processes, the next +best route is to [uninstall](https://github.com/netdata/netdata/blob/master/packaging/installer/UNINSTALL.md) and then try a fresh installation using the [one-line +installer](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/kickstart.md). + +You can also post to our [community forums](https://community.netdata.cloud/c/support/13) or create a new [bug +report](https://github.com/netdata/netdata/issues/new?assignees=&labels=bug%2Cneeds+triage&template=BUG_REPORT.yml). |
