# Step 4: Start Sharder and Miner Containers

To start all the miner and sharder containers navigate to the `0chain/docker.local/<miner/sharder|i>` directories and run the start script. For example, let's run 1 sharder and 3 miners.

1. Open four different terminal tabs and in the first terminal tab navigate to the `0chain/docker.local/sharder1` directory using

```
cd 0chain/docker.local/sharder1/
```

2.Run the following command for starting the sharder

```
../bin/start.b0sharder.sh
```

3.Wait till the Cassandra is started and the sharder is ready to listen to requests.&#x20;

Here is a screenshot of sharder up and running:

4\. Repeat steps 1 and 2 by changing the sharder1 directory to (sharder 2,3 etc) in new terminal tabs to start more sharders.

Notes :

* Run each sharder on new terminal tab and start sharder before miners as they need the genesis magic block.
* Run the command specified in step 2 by only navigating to sharder directories.
* If you are not able to locate sharder directories, have a look at the[ Initialize the Miner and sharder directories](https://github.com/0chain/gitbookdocs/blob/main/broken-reference/README.md) section.
* **For a minimal working setup, at least run 1 sharder and 3 miners.**

5\. To run the miner containers in other three terminal tabs,first navigate to `0chain/docker.local/miner1` directory using

```
cd 0chain/docker.local/miner1/
```

6\. Run the following command for starting the miner

```
../bin/start.b0miner.sh
```

Wait till the miner is ready to accept connections. Here is a screenshot of miner up and running.

7\. Repeat steps 5 and 6 by changing the miner1 directory to (miner 2,3 etc) in new terminal tabs to start more miners.

**Notes:**

* Run each miner on a new terminal tab
* To avoid errors, run the command specified in step 6 by only navigating to miner directories.
* If you are not able to locate miner directories, have a look at the [Initialize the Miner and sharder directories](https://github.com/0chain/gitbookdocs/blob/main/broken-reference/README.md) section.
* **For a minimal working setup, at least run 1 sharder and 3 miners.**
