There are three ways to start a mainnet node.
1. Use snapshots
Snapshot link
# 1. Build exchaind
git clone -b latest_version https://github.com/okex/exchain.git # The latest version can be viewed through this link(https://github.com/okex/exchain/releases/latest
cd exchain).
make mainnet # Compile the mainnet. The default database is leveldb.
make mainnet WITH_ROCKSDB=true # Compile the mainnet. The used database is rocksdb.
# 2. Initialize the configuration of exchain node
export EXCHAIND_PATH=~/.exchaind (or other directory)
exchaind init your_custom_moniker --chain-id exchain-66 --home ${EXCHAIND_PATH}
# 3. Download snapshot
rm -rf ${EXCHAIND_PATH}/data
cd ${EXCHAIND_PATH}
wget https://ok-public-hk.oss-cn-hongkong.aliyuncs.com/cdn/okexchain/snapshot/okexchain-$version-$date-$height_xxx.tar.gz
tar -zxvf okexchain-$version-$date-$height_xxx.tar.gz
# 4. Start exchaind
# Start a leveldb node
exchaind start --chain-id exchain-66 --home ${EXCHAIND_PATH}
# Start a rocksdb node
exchaind start --chain-id exchain-66 --db_backend rocksdb --home ${EXCHAIND_PATH}
2. Use Genesis File
# 1. Build exchain
git clone -b latest_version https://github.com/okex/exchain.git # The latest version can be viewed through this link(https://github.com/okex/exchain/releases/latest).
cd exchain
make mainnet # Compile the mainnet. The default database is leveldb.
make mainnet WITH_ROCKSDB=true # Compile the mainnet. The used database is rocksdb.
# 2. Initialize the configuration of exchain node
export EXCHAIND_PATH=~/.exchaind (or other directory)
exchaind init your_custom_moniker --chain-id exchain-66 --home ${EXCHAIND_PATH}
# 3. Download the genesis file(genesis.json)
wget https://raw.githubusercontent.com/okex/mainnet/main/genesis.json -O ${EXCHAIND_PATH}/config/genesis.json
# 4. Start exchaind
# Start a node using leveldb
exchaind start --chain-id exchain-66 --home ${EXCHAIND_PATH}
# Start a node using rocksdb
exchaind start --chain-id exchain-66 --db_backend rocksdb --home ${EXCHAIND_PATH}
Notice
If you're using s3 snapshot to start a node, please make sure to add pruning=nothing to the startup parameters, as the default value of pruning is default which will prune the data.
In addition, it is recommended to configure the following parameters according to your needs.
--max-open=10000 Maximum number of connections, 1000 for default. Increasing this value can provide more connections that the rpc service can receive.--disable-abci-query-mutex=1 The switch of lock in abci query, 0 for default (0 means closed, 1 means open). The query performance can be improved when it is open.--fast-query=1 The switch of fast query mode, 0 for default (0 means closed, 1 means open). When this switch is open, the query data will be additionally recorded to watch.db in order to improve the query performance.--enable-bloom-filter=1 The switch of bloom filter, 0 for default (0 means closed, 1 means open). The query performance for eth_getLogs will be improved when it is open.--mempool.size=10000 The mempool size, 2000 for default. Increasing this value will increase the quanity's limit of transactions stored in mempool.
You can use exchaind start -h to see more details.
3. Start with docker+snapshot
# 1. Initialize the configuration of exchain node
export EXCHAIND_PATH=~/.exchaind (or other directory)
exchaind init your_custom_moniker --chain-id exchain-66 --home ${EXCHAIND_PATH}
# 2. Download snapshot
rm -rf ${EXCHAIND_PATH}/data
cd ${EXCHAIND_PATH}
# Please download the rocksdb snapshot corresponding to the mainnet as this mirror uses rocksdb.
wget https://ok-public-hk.oss-cn-hongkong.aliyuncs.com/cdn/okexchain/snapshot/okexchain-$version-$date-$height_xxx.tar.gz
tar -zxvf okexchain-$version-$date-$height_xxx.tar.gz
# 3. Download the docker image
docker pull okexchain/fullnode-mainnet:latest # This image uses data in rocksdb snapshot.
# 4. Run docker based on the snapshot downloaded in the previous step.
docker run -d --name exchain-mainnet-fullnode -v ~/.exchaind/data:/root/.exchaind/data/ -p 8545:8545 -p 26656:26656 okexchain/fullnode-mainnet:latest
