Overview

EOSIO comes with a number of programs. The primary ones that you will use, and the ones that are covered here, are:

  • nodeos - server-side blockchain node component
  • cleos - command line interface to interact with the blockchain and to manage wallets
  • keosd - component that manages EOSIO wallets

The basic relationship between these components is illustrated in the following diagram. In the sections that follow, you will build the EOSIO components, and deploy them in a single host, single node test network (testnet) configuration. Basic Relationships Between EOSIO Components

Getting the Code

To download all of the code, clone the eos repository and its submodules.

git clone https://github.com/EOSIO/eos --recursive

If a repository is cloned without the --recursive flag, the submodules can be retrieved after the fact by running this command from within the repo:

git submodule update --init --recursive

Throughout the EOSIO documentation and tutorials, reference will be made to the top level of your local EOSIO source repository. The location where you just cloned the eos repository is that location. The notation ${EOSIO_SOURCE} represents the same thing. For example, if you ran the git clone operation in a folder called ~/myprojects, then ${EOSIO_SOURCE}=~/myprojects/eos. Note that ${EOSIO_SOURCE} is used in the documentation for notational purposes only. No environment variable is implied or required. More commonly, for simplicity, this and other documents might simply refer to eos. This is equivalent to ${EOSIO_SOURCE}.

Building EOSIO

The simple approach to building EOSIO is to use the automated build script. The automated approach is documented next. Instructions to build EOSIO manually are described in the section Manually Building EOSIO, farther down in this document.

The build places content in the eos/build folder. The executables can be found in subfolders within the eos/build/programs folder.

Automated build script

There is an automated build script that can install all dependencies and build EOSIO. The script supports the following operating systems. We are working on supporting other Linux/Unix distributions in future releases.

  1. Amazon 2017.09 and higher.
  2. Centos 7.
  3. Fedora 25 and higher (Fedora 27 recommended).
  4. Mint 18.
  5. Ubuntu 16.04 (Ubuntu 16.10 recommended).
  6. MacOS Darwin 10.12 and higher (MacOS 10.13.x recommended).

System Requirements (all platforms)

  • 8GB RAM free required
  • 20GB Disk free required

Run the build script

Run the build script from the eos folder.

cd eos
./eosio_build.sh

Build validation

Optionally, a set of tests can be run against your build to perform some basic validation. To run the test suite after building, start mongod and the run make test.

On Linux platforms:

~/opt/mongodb/bin/mongod -f ~/opt/mongodb/mongod.conf &

On MacOS:

/usr/local/bin/mongod -f /usr/local/etc/mongod.conf &

Followed by this on all platforms:

cd build
make test

Install the executables

For ease of contract development, content can be installed in the /usr/local folder using the make install target. This step is run from the build folder. Adequate permission is required to install, so we use the sudo command with make install.

cd build
sudo make install

Creating and Launching a Single Node Testnet

After successfully building the project, the nodeos binary should be present in the build/programs/nodeos folder. nodeos can be run directly from the build folder using programs/nodeos/nodeos, or you can cd programs/nodeos to change into the folder and run the nodeos command from there. Here, we run the command within the programs/nodeos folder.

You can start your own single-node blockchain with this single command:

cd programs/nodeos
./nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::account_history_api_plugin

When running nodeos you should get log messages similar to below. It means the blocks are successfully produced.

1575001ms thread-0   chain_controller.cpp:235      _push_block          ] initm #1 @2017-09-04T04:26:15  | 0 trx, 0 pending, exectime_ms=0

...
eosio generated block 046b9984... #101527 @ 2018-04-01T14:24:58.000 with 0 trxs
eosio generated block 5e527ee2... #101528 @ 2018-04-01T14:24:58.500 with 0 trxs
...

At this point, nodeos is running with a single producer, eosio.

The following diagram depicts the single host testnet that we just created. For the curious, in this configuration, we chose to use nodeos for wallet management. The eosio::wallet_api_plugin that we specified on the nodeos command line has a dependency on eosio::wallet_plugin that does the wallet management, causing it to load automatically. Other alternatives are discussed in the Comprehensive Accounts & Wallets Tutorial tutorial. Regardless of configuration chosen, cleos is used to manage the wallets, manage the accounts, and invoke actions on the blockchain. Single Node Testnet without keosd

Advanced Steps

The more advanced user will likely have need to modify the configuration. nodeos uses a custom configuration folder. The location of this folder is determined by your system.

  • Mac OS: ~/Library/Application Support/eosio/nodeos/config
  • Linux: ~/.local/share/eosio/nodeos/config

The build seeds this folder with a default genesis.json file. A configuration folder can be specified using the --config-dir command line argument to nodeos. If you use this option, you will need to manually copy a genesis.json file to your config folder.

nodeos will need a properly configured config.ini file in order to do meaningful work. On startup, nodeos looks in the config folder for config.ini. If one is not found, a default config.ini file is created. If you do not already have a config.ini file ready to use, run nodeos and then close it immediately with Ctrl-C. A default configuration (config.ini) will have been created in the config folder. Edit the config.ini file, adding/updating the following settings to the defaults already in place:

   # Load the testnet genesis state, which creates some initial block producers with the default key
   genesis-json = /path/to/eos/source/genesis.json
   # Enable production on a stale chain, since a single-node test chain is pretty much always stale
   enable-stale-production = true
   # Enable block production with the testnet producers
   producer-name = eosio
   # Load the block producer plugin, so you can produce blocks
   plugin = eosio::producer_plugin
   # Wallet plugin
   plugin = eosio::wallet_api_plugin
   # As well as API and HTTP plugins
   plugin = eosio::chain_api_plugin
   plugin = eosio::http_plugin
   # This will be used by the validation step below, to view account history
   plugin = eosio::account_history_api_plugin

Now it should be possible to run nodeos and see it begin producing blocks.

programs/nodeos/nodeos

nodeos stores runtime data (e.g., shared memory and log content) in a custom data folder. The location of this folder is determined by your system.

  • Mac OS: ~/Library/Application Support/eosio/nodeos/data
  • Linux: ~/.local/share/eosio/nodeos/data

A data folder can be specified using the --data-dir command line argument to nodeos.

Manually Building EOSIO

Manual build

To manually build, use the following steps to create a build folder within your eos folder and then perform the build. The steps below assume the eos repository was cloned into your home (i.e., ~) folder. It is also assumes that the necessary dependencies have been installed. See Manual Installation of the Dependencies.

cd ~
mkdir -p ~/eos/build && cd ~/eos/build

On Linux platforms, use this cmake command:

cmake -DBINARYEN_BIN=~/binaryen/bin -DWASM_ROOT=~/wasm-compiler/llvm -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib -DBUILD_MONGO_DB_PLUGIN=true ..

On MacOS, use this cmake command:

cmake -DBINARYEN_BIN=~/binaryen/bin -DWASM_ROOT=/usr/local/wasm -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib -DBUILD_MONGO_DB_PLUGIN=true ..

Then on all platforms:

make -j$( nproc )

Out-of-source builds are also supported. To override clang's default choice in compiler, add these flags to the CMake command:

-DCMAKE_CXX_COMPILER=/path/to/c++ -DCMAKE_C_COMPILER=/path/to/cc

For a debug build, add -DCMAKE_BUILD_TYPE=Debug. Other common build types include Release and RelWithDebInfo.

Docker

Simple and fast setup of EOSIO on Docker is also available. You can find up to date information about EOSIO Docker in the Docker Readme.

Install Dependencies

  • Docker Docker 17.05 or higher is required

Build EOSIO image

$ git clone https://github.com/EOSIO/eos.git --recursive
$ cd eos/Docker
$ docker build . -t eosio/eos

Start nodeos docker container only

$ docker run --name nodeos -p 8888:8888 -p 9876:9876 -t eosio/eos start_nodeos.sh arg1 arg2

By default, all data is persisted in a docker volume. It can be deleted if the data is outdated or corrupted:

$ docker inspect --format '{{ range .Mounts }}{{ .Name }} {{ end }}' nodeos
fdc265730a4f697346fa8b078c176e315b959e79365fc9cbd11f090ea0cb5cbc
$ docker volume rm fdc265730a4f697346fa8b078c176e315b959e79365fc9cbd11f090ea0cb5cbc

Alternately, you can directly mount host directory into the container

$ docker run --name nodeos -v /path-to-data-dir:/opt/eos/bin/data-dir -p 8888:8888 -p 9876:9876 -t eosio/eos start_nodeos.sh arg1 arg2

Get chain info

$ curl http://127.0.0.1:8888/v1/chain/get_info

Start both nodeos and keosd containers

$ docker-compose up

After docker-compose up, two services named nodeos and keosd will be started. nodeos service will expose ports 8888 and 9876 to the host. keosd service does not expose any port to the host, it is only accessible to cleos when runing cleos is running inside the keosd container as described in "Execute cleos commands" section.

Execute cleos commands

You can run the cleos commands via a bash alias.

$ alias cleos='docker-compose exec keosd /opt/eos/bin/cleos -H nodeos'
$ cleos get info
$ cleos get account inita

Upload sample exchange contract

$ cleos set contract exchange contracts/exchange/exchange.wast contracts/exchange/exchange.abi

If you don't need keosd afterwards, you can stop the keosd service using

$ docker-compose stop keosd

Change default configuration

You can use docker compose override file to change the default configurations. For example, create an alternate config file config2.ini and a docker-compose.override.yml with the following content.

version: "2"

services:
  nodeos:
    volumes:
      - nodeos-data-volume:/opt/eos/bin/data-dir
      - ./config2.ini:/opt/eos/bin/data-dir/config.ini

Then restart your docker containers as follows:

$ docker-compose down
$ docker-compose up

Clear data-dir

The data volume created by docker-compose can be deleted as follows:

$ docker volume rm docker_nodeos-data-volume

Troubleshooting Guide

  1. You get an error such as St9exception: content of memory does not match data expected by executable when trying to start nodeos

Try restarting nodeos with --resync

  1. How do I find which version of nodeos I'm running or connecting to?

Use cleos -H ${nodeos_host} -p ${nodeos_port} get info and you will see the version number in the field called server_version
