+# Restart Grafana
+
+Users often need to restart Grafana after they have made configuration changes. This topic provides detailed instructions on how to restart Grafana supported operating systems.
+
+- [Windows](#windows)
+- [MacOS](#macos)
+- [Linux](#linux)
+- [Docker](#docker)
+
+## Windows
+
+To restart Grafana:
+
+1. Open the Services app.
+1. Right-click on the **Grafana** service.
+1. In the context menu, click **Restart**.
+
+## macOS
+
+Restart methods differ depending on whether you installed Grafana using Homebrew or as standalone macOS binaries.
+
+### Restart Grafana using Homebrew
+
+Use the [Homebrew](http://brew.sh/) restart command:
+
+```bash
+brew services restart grafana
+```
+### Restart standalone macOS binaries
+
+To restart Grafana:
+
+1. Open a terminal and go to the directory where you copied the install setup files.
+1. Run the command:
+
+```bash
+./bin/grafana-server web
+```
+## Linux
+
+Restart methods differ depending on whether your Linux system uses `systemd` or `init.d`.
+
+### Restart the server with systemd
+
+To restart the service and verify that the service has started, run the following commands:
+
+```bash
+sudo systemctl restart grafana-server
+sudo systemctl status grafana-server
+```
+
+Alternately, you can configure the Grafana server to restart at boot:
+
+```bash
+sudo systemctl enable grafana-server.service
+```
+
+> **Note:** SUSE or OpenSUSE users may need to start the server with the systemd method, then use the init.d method to configure Grafana to start at boot.
+
+### Restart the server with init.d
+
+To restart the service, run the following command:
+
+```bash
+sudo service grafana-server restart
+```
+
+or
+
+```bash
+sudo /etc/init.d/grafana-server restart
+```
+
+Verify the status:
+
+```bash
+sudo service grafana-server status
+```
+
+or
+
+```bash
+sudo /etc/init.d/grafana-server status
+```
+
+Alternately, you can configure the Grafana server to restart at boot:
+
+```bash
+sudo update-rc.d grafana-server defaults
+```
+## Docker
+
+To restart the Grafana service, use the `docker restart` command.
+
+`docker restart grafana`
+
+Alternately, you can use the `docker compose restart` command to restart Grafana. For more information, refer to [docker compose documentation](https://docs.docker.com/compose/).
+
+### Docker compose example
+
+Configure your `docker-compose.yml` file. For example:
+
+```bash
+grafana:
+  image: grafana/grafana:latest
+  ports:
+    - "3000:3000"
+  environment:
+    - TERM=linux
+    - GF_INSTALL_PLUGINS=grafana-clock-panel,grafana-piechart-panel,grafana-polystat-panel
+```
+
+Start the Grafana server:
+
+`docker-compose up`
+
+This starts the Grafana server along with the three plugins specified in the YAML file.
+
+To restart the running container, use this command:
+
+`docker-compose restart grafana`
