# Step 3: Initialize and Build the Züs components ### Initialize the Sharder and Miner directories 1. Navigate to 0chain directory ``` cd 0chain ``` 2\. Run the `init.setup.sh` script located in the `docker.local/bin` directory using the command ``` ./docker.local/bin/init.setup.sh ``` After running the script you will see the sharder and miner directories populated in `docker.local` folder. 3\. Lets verify whether the directories exist by navigating to `docker.local` folder and running ``` ls docker.local/ ``` The output should be similar to this: ``` Makefile build.benchmarks build.sc_unit_test build.unit_test miner2 miner6 sharder2 benchmarks build.genkeys build.sharder config miner3 miner7 sharder3 bin build.magicBlock build.swagger docker-clean miner4 miner8 sharder4 build.base build.miner build.test.multisigsc miner1 miner5 sharder1 sql_script ``` ### Build the miner and sharder containers \ 1\. Navigate to 0chain directory ``` cd 0chain ``` 2\. First build the base containers using the script.(This may take few minutes) ``` ./docker.local/bin/build.base.sh ``` Screenshot after successful build:

Base Build

3. Build mocks from the Makefile in the repo, from 0chain directory run: ``` make build-mocks ``` **Note:** Mocks have to be built once in the beginning. Building mocks require mockery and brew which can be installed from [**here**](/guides/setup-a-blockchain/additional-tips-and-troubleshooting-for-mac.md#install-homebrew-and-mockery-on-mac-and-linux) **.** 4. For building the sharder containers use the following command : ``` ./docker.local/bin/build.sharders.sh ``` Screenshot of successful sharder build:

5. Build the miner containers using ``` ./docker.local/bin/build.miners.sh ``` Screenshot of a successful miner build:

### Initialize the blobber directories 1. Navigate to blobber directory ``` cd blobber ``` 2\. Inside blobber directory, run the commands below .The first command makes the shell script executable and while the next ones execute the shell script to create blobber directories. ``` chmod +x ./docker.local/bin/blobber.init.setup.sh ./docker.local/bin/blobber.init.setup.sh ``` **NOTE**: For Mac : ``` chmod +x ./docker.local/bin/blobber.init.setup-mac.sh ./docker.local/bin/blobber.init.setup-mac.sh ``` After running the script you will see the blobber directories populated in `docker.local` folder 3\. Let's verify whether the directories exist by navigating to `docker.local` folder and running ``` ls docker.local/ ``` The output should be like this: ``` b0docker-compose.yml blobber4 Dockerfile bin blobber5 IntegrationTestsBlobberDockerfile blobber1 blobber6 keys_config blobber2 docker-clean p0docker-compose.yml blobber3 docker-compose.yml ValidatorDockerfilecd blobber/config ``` 4. Navigate to the config directory using ``` cd blobber/config ``` Use the nano editor to edit the `block`\_`worker` field for both files : ``` nano 0chain_blobber.yaml ``` and ``` nano 0chain_validator.yaml ``` **Note : Change the default value of `block_worker` field with the following:** [**http://198.18.0.98:9091/**](http://198.18.0.98:9091/) **for the local chain.** ### Build the blobber containers 1. Go back to `blobber` directory ``` cd blobber ``` 2\. Now run the following scripts located in the `docker.local/bin` directory. ``` ./docker.local/bin/build.base.sh ./docker.local/bin/build.blobber.sh ./docker.local/bin/build.validator.sh ``` Screenshot after a successful blobber build:

**Note:** The blobber scripts defined above works fine for Linux and Intel Mac **.**If you want to run blobber and validator on Apple Silicon Mac(M1 or M2) follow the guide [here](https://github.com/0chain/blobber/blob/staging/dev.local/README.md). In case you are still facing issues with blobbers on M1 or M2 mac check [Troubleshooting Guide for Blobbers Setup (Mac M1 or M2)](/guides/setup-a-blockchain/additional-tips-and-troubleshooting-for-mac.md#troubleshooting-guide-for-blobbers-setup-mac-m1-or-m2)[.](/guides/setup-a-blockchain/additional-tips-and-troubleshooting-for-mac.md#troubleshooting-guide-for-blobbers-setup-mac-m1-or-m2) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
