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.
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 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 usingcd 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 section.
- For a minimal working setup, at least run 1 sharder and 3 miners.
