Compilation and deployment of eosio

1. Explanation of terms

  1. The creation node (BIOS) is used to create the initial block and load the basic contract for other nodes to connect synchronously.

  2. The miner node (BP) is mainly used for the production of synchronous blocks, and the cost incurred in calculating the contract belongs to the miner account.

  3. The query node does not generate blocks, synchronizes block information, and provides block information query function.

  4. The private key is used for signature operation. The private key can generate a unique corresponding public key.

  5. The public key is used to verify the signature of the private key.

  6. When the private key is generated and saved in the wallet, the private key list will be read from the wallet for signature.

  7. The bandwidth is divided into cpu bandwidth and net bandwidth. Each execution of the contract will consume a certain bandwidth (deducted from the account).

  8. A section of executable code in the chain is bound to the account, and each account can only bind one contract.

  9. Account stores user information, including balance, bandwidth, contract (if any), etc.

  10. Total votes total votes = total number of currencies issued.

  11. The voters pledged money to vote for the miners. When the number of votes of the miners is more than 15% of the total votes, the genesis node stops producing blocks and transfers them to the miners' production blocks.

    The so-called miner node and query node are only used to distinguish whether to produce different configurations of blocks.

2. Node code compilation and program installation

Note: later compilation depends on git, so make sure that. Git of the code root directory is complete and Git is installed in the system. Take ubuntu system as an example, and other system steps are similar.

  1. Install GIT first, ignore this step if already installed

    sudo apt update && sudo apt install git -y
  2. Clone the latest code from GIT

    git clone --recursive --depth 1
  3. Auto compile with eosio

    The script will check the system dependency library and install it automatically. Please pay attention to the administrator permission prompt. If the download of dependency library is interrupted, please check the network status and execute it again.

    cd eosio

    The formal environment can use the local cmake flags environment variable to specify the root public key eosio root key and the system currency symbol core symbol name

  4. Packaging and installation

    If the compilation is successful, the ASCII drawing prompt of 'EOSIO' will appear. Please perform the following operations to install the program into the system. If there is a compilation error, please submit the error prompt to the relevant personnel for check and solution.

     cd build/packages
     bash ./ [brew|deb|rpm]
     sudo dpkg -i eosio-v1.7.3.deb
     sudo yum install eosio-v1.7.3.rpm
     sudo rpm -ivh eosio-v1.7.3.rpm

    Parameter Description:

    • brew mac system
    • deb ubuntu system
    • rpm redhat system
  5. Recompile If there is any code modification or version update, please close the currently running wallet and node programs, clear the programs installed in the system, and then compile.

    pkill -2 keosd nodeos
    sudo apt remove eosio
    sudo yum remove eosio

3. Default profile directory

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

4. Create default wallet and public private key

  1. Start wallet service

    keosd --unlock-timeout 3600 # Wallet relocks in 3600 seconds
  2. Create Wallet

    Please save the output wallet code. It will be used the next time you open the wallet.

    cleos wallet create -n default
    #Open wallet
    cleos wallet open -n default
  3. Create public private key

    cleos create key
  4. Import the private key generated in the previous step into the wallet

    cleos wallet import -n default --private-key [private key]

5. General configuration

6. Configuration of Genesis node

6.1. Start parameter configuration

  1. To create a public and private key for the eosio system account, see 4. Create wallet and public private key

  2. Modify the initial key of genesis.json to the public key generated in the previous step

  3. Start the node and fill in the public and private keys generated in step 1

     nodeos --agent-name "eosio bios" --producer-name "eosio" \

7. Miner node configuration

1. Register miner account

  1. For public and private keys to create a miner account, see 4. Create wallet and public private key

  2. Create miner account

    cleos system newaccount --stake-net [quantity] --stake-cpu [quantity] --buy-ram-kbytes 8192 \
        [creater] [name] [OwnerKey] [ActiveKey] -p [creater]
    # Parameter description
    # Creator account of the creator miner account.
    # Name the name of the miner's account.
    # quantity purchases bandwidth resources and deducts them from the creator's account.
    # OwnerKey is the same as ActiveKey, the public key of the miner account, that is, the public key generated in the previous step.
    # Example
    cleos system newaccount --stake-net "50.0000 EOS" --stake-cpu "50.0000 EOS" --buy-ram-kbytes 8888888 eosio eosnewbpa \
    EOS7n1U9Z2NQeVEvQZYjHCedNXRVWshmmuGH2j3r6bD4c8fH4U8QL EOS7n1U9Z2NQeVEvQZYjHCedNXRVWshmmuGH2j3r6bD4c8fH4U8QL -p eosio
  3. Transfer to miner account

    cleos transfer [from] [recipient] [amount] [momo]
    # Parameter description
    # from transfer account No
    # recipient receiving transfer account
    # amount
    # momo notes
    # Example
    cleos transfer eosio eosnewbpa "9000000000.0000 EOS" "trans to eosnewbpa"
  4. Registered as a miner

    cleos system regproducer [name] [ActiveKey] [url]
    # Parameter description
    # name miner account
    # ActiveKey public key of miner account
    # url miner's website
    cleos system regproducer eosnewbpa  EOS7n1U9Z2NQeVEvQZYjHCedNXRVWshmmuGH2j3r6bD4c8fH4U8QL
  5. Mortgage corresponding resources

    cleos system delegatebw [name] [name] [stake_net_quantity] [stake_cpu_quantity]
    # Parameter description
    # name miner account
    # The network bandwidth resources mortgaged by make net quantity
    # The CPU bandwidth resources mortgaged by "make" CPU "quantity
    # Example
    cleos system delegatebw eosnewbpa eosnewbpa '4400000000.0000 EOS' '4400000000.0000 EOS'
  6. Vote for yourself

    cleos system voteproducer prods [voter] [producers] -p [voter]
    # Parameter description
    # voter miner account
    # Network bandwidth resources mortgaged by producers
    cleos system voteproducer prods eosnewbpa eosnewbpa

2. Start parameter configuration

  1. To create a public and private key for the eosio system account, see Creating wallets and public and private keys

  2. Modify the initial key of genesis.json to generate the public key for the BIOS

  3. Start the node and fill in the public and private keys generated in step 1

    Suppose that bios node and BP node are known.

    nodeos --agent-name "eosnewbpa" --producer-name "eosnewbpa" \
        --signature-provider [public key]=KEY:[private key] \
        --p2p-server-address "" --http-server-address "" \
        --p2p-peer-address "" --p2p-peer-address ""

8. Query node configuration

The query node configuration is similar to the miner node configuration, except that it is not registered as a miner, and the query node is often used for data query. It is recommended to open the Mongo DB plugin plug-in. Mongo DB plugin is a plug-in for saving block transaction information to mongodb.

Suppose that the bios node, BP node and are known, and the mongo_db_plugin plug-in is enabled for all three nodes.

nodeos --agent-name "eosnewbpb" --producer-name "eosnewbpb" \
  --signature-provider [public key]=KEY:[private key] \
  --p2p-server-address "" --http-server-address "" \
  --p2p-peer-address "" --p2p-peer-address "" --p2p-peer-address "" \
  --plugin eosio::mongo_db_plugin --mongodb-uri mongodb://

9. recommendations

  1. From the perspective of security, do not disclose the private key to others. After knowing the private key of the account, you can manipulate the account at will.

  2. If you use a private key generated by a mnemonic, use a more complex mnemonic.

  3. Many of the parameters passed in above are for demonstration. If it is formally deployed, it is recommended to use the configuration file.

  4. It is recommended to use SIGINT signal to shut down the node and prevent the program from generating dirty data.

    pkill -2 keosd nodeos
  5. If dirty data is generated, use the -- replay blockchain parameter or the -- delete all blocks parameter to start the node and resynchronize the data.

  6. Before starting the node, please confirm that the time and time zone are correct, and the offset of time will affect the block data verification.

    sudo mv /etc/localtime  /etc/localtime.bak
    sudo ln -s /usr/share/zoneinfo/UTC /etc/localtime
    # Update system time with ntpdate
    sudo apt install ntpdate ntp -y # yum install ntpdate ntp -y
    sudo timedatectl set-timezone UTC
    sudo ntpdate -u
    sudo hwclock --systohc # Write hardware
    # Start ntpd service
    sudo systemctl enable ntp # systemctl enable ntpd
    sudo systemctl start ntp # systemctl start ntpd
