For other full node operators

The documentation is designed for Liker Land and LikeCoin v2. For information on 3ook.com and LikeCoin v3, please visit docs.3ook.com and dao.like.co.

For non-validator nodes, or for validator nodes who cannot join the upgrade process, you may setup a full node or replace your current full node after the upgrade is finished.

1. Clone the software if you haven't already have one:

   git clone https://github.com/likecoin/likecoin-chain

2. Switch to the fotan-1 branch:

   git checkout fotan-1

3. Backup docker-compose.yml if you have one:

   cp docker-compose.yml docker-compose.yml.sheungwan

4. Setup docker-compose.yml and .env file:

   cp docker-compose.yml.template docker-compose.yml
   cp .env.template .env

5. Get the genesis URL, which will be generated (uploaded) during the upgrade process by validators.

6. Setup .env file according to the chain parameter:

   • LIKECOIN_DOCKER_IMAGE: "likecoin/likecoin-chain:fotan-1"

   • LIKECOIN_CHAIN_ID: "likecoin-mainnet-2"

   • LIKECOIN_UID: normally keep it as "1000" is fine, but if you are using root user under Linux (e.g. in some VPS) then you should change it to "0".

   • LIKECOIN_MONIKER: the original moniker (in .liked/config/config.toml, search for moniker). If not sure, any name indicating your node is OK.

   • LIKECOIN_GENESIS_URL: https://gist.githubusercontent.com/williamchong/de1bdf2b2a8f3bce50a4b5e46af26959/raw/4e21bff586771c849d22e1916bcb88c6463fbaa0/genesis.json

   • LIKECOIN_SEED_NODES: [email protected]:26656,[email protected]:26656

7. Backup the original node if you have one:

   mv .liked .liked.bak

8. Initialize the node with new software:

   docker-compose run --rm init

9. Re-import the keys and address books from the old node if you have one:

   cp \
     .liked.bak/config/node_key.json \
     .liked.bak/config/priv_validator_key.json \
     .liked.bak/config/addrbook.json \
     .liked/config

10. Start up the node:

    docker-compose up -d

11. Wait for synchronization, which you may check by going to http://localhost:26657/status and see result.sync_info.catching_up . If it shows false then the node has caught up.

12. If you have keystore, you may migrate the keys by running the following command:

    docker-compose run liked-command keys migrate /host/.likecli
