In this guide we’ll:Set up an Initia Full node with a custom DB backendTune configuration parametersTune system-level settingsAssumptions: You have a VPS / bare metal server running Ubuntu >22.04 at hand. While we won’t go over the steps for provisioning a server, we’ll recommend selecting for the recommended specs:CPU: 16 coresMemory: 32GB RAMDisk: 2 TB NVMe/SSD Storage with Write Throughput > 1000 MiBpsBandwidth: 100 MbpsIf on bare-metal, we recommend a RAID0 disk configuration for optimal performance.System-level performance tuningWe’ll be using the tuned-adm package to fine-tune kernel-level configurations. tuned-adm is a system tuning daemon for Linux that can be used to optimize performance for certain tasks. We find the throughput-performance profile to be the most effective. First, install tuned-adm and required packages:​sudo apt install tuned tuned-utils tuned-utils-systemtap Adjust the existing throughput-performance profile to decrease the likelihood of moving memory to swap:​sudo sed -i 's/^vm\.swappiness=10$/vm.swappiness=1/' /usr/lib/tuned/throughput-performance/tuned.conf Enable the profile:sudo tuned-adm profile throughput-performance ​Verify that the profile is now active:​tuned-adm active Installing Initia w/ PebbleDBPebbleDB is a fast, RocksDB-inspired key-value store that enhances read/write performance. By efficiently moving more operations into memory and improving caching, PebbleDB can reduce disk requirements. It offers better compression, quicker pruning, and more efficient memory usage, resulting in less I/O overhead. In our tests, pruning operation times decreased by over 75%. Additionally, read and write operations per second significantly decreased due to improved caching. Here, we’ll be using pebbledb in place of the default leveldb Install pre-requisitessudo apt install jq build-essential curl wget Install gosudo rm -rf /usr/local/go curl -Ls https://go.dev/dl/go1.22.2.linux-amd64.tar.gz | sudo tar -C /usr/local -xz echo "" >> $HOME/.profile echo 'export GOPATH=$HOME/go' >> $HOME/.profile echo 'export GOBIN=$GOPATH/bin' >> $HOME/.profile echo 'export PATH=$PATH:/usr/local/go/bin:$GOBIN' >> $HOME/.profile source $HOME/.profile` Confirm installationgo version Clone the repocd $HOME git clone https://github.com/initia-labs/initia.git git checkout v0.2.21 # <-- remember to check for up to date version Intall Initia Node (initiad). Usually, you’d run make install to install the binary. Here though, we’ll make some modifications so that the reuslting binary uses pebbledb as its database backend:go mod edit -replace github.com/cometbft/cometbft-db=github.com/cometbft/cometbft-db@v0.12.0 go mod tidy make BUILD_TAGS=pebbledb LDFLAGS="-w -s -X github.com/cosmos/cosmos-sdk/types.DBBackend=pebbledb \ -X github.com/cosmos/cosmos-sdk/version.Version=v0.2.21 \ -X github.com/cosmos/cosmos-sdk/version.Commit=$(git log -1 --format='%H') \ -X github.com/cosmos/cosmos-sdk/version.ServerName=initiad \ -X github.com/cosmos/cosmos-sdk/version.ClientName=initiad \ -X github.com/cosmos/cosmos-sdk/version.Name=initia \ -X github.com/cosmos/cosmos-sdk/version.AppName=initia" build cp build/initiad $GOBIN/initiad Verify installationinitiad version --long Initilatise configurationsinitiad init pebblenode --chain-id initiation-1 cd $HOME/.initia/config rm genesis wget -O genesis.json https://snapshots.polkachu.com/testnet-genesis/initia/genesis.json Set seeds (h/t polkachu)seeds="ade4d8bc8cbe014af6ebdf3cb7b1e9ad36f412c0@testnet-seeds.polkachu.com:25756,86bd5cb6e762f673f1706e5889e039d5406b4b90@seed.initia.testnet.node75.org:20456" sed -i "s/^seeds *=.*/seeds = \"$seeds\"/" $HOME/.initia/config/config.toml Set minimum gas pricesmin_gas_price="0.002uinit,0.002move\/944f8dd8dc49f96c25fea9849f16436dcfa6d564eec802f3ef7f8b3ea85368ff" sed -i "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"$min_gas_price\"/" $HOME/.initia/config/app.toml Set pruning to custompruning="custom" pruning_keep_recent="100" pruning_interval="10" sed -i "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.initia/config/app.toml sed -i "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.initia/config/app.toml sed -i "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.initia/config/app.toml sed -i -e "s/^min-retain-blocks *=.*/min-retain-blocks = 3000/" ${HOME}/.initia/config/app.toml Set PebbleDB backenddb_backend="pebbledb" sed -i "s/^db_backend *=.*/db_backend = \"$db_backend\"/" $HOME/.initia/config/config.toml sed -i "s/^app-db-backend *=.*/app-db-backend = \"$db_backend\"/" $HOME/.initia/config/app.toml Install systemd servicesudo tee /etc/systemd/system/initiad.service > /dev/null <<EOF [Unit] Description=Initia node Service After=network.target [Service] Type=simple User=$USER ExecStart=$GOBIN/initiad start Restart=on-failure RestartSec=10 LimitNOFILE=65535 [Install] WantedBy=multi-user.target EOF Statesync: save this as a file statesync.sh and execute it#!/bin/bash SNAP_RPC="https://rpc.initiation-1.initia.xyz:443" curl -s $SNAP_RPC/status > /dev/null if [ $? -ne 0 ]; then echo "failed querying rpc, exiting" exit fi if [ ! -d $HOME/.initia ]; then echo "home .initia does not exist, exiting" exit fi if [ ! -f /etc/systemd/system/initiad.service ]; then echo "servvice initiad does not exist, exiting" exit fi LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \ BLOCK_HEIGHT=$((LATEST_HEIGHT - 7500)); \ TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash) sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \ s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \ s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \ s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.initia/config/config.toml sudo systemctl stop initiad if [ -d $HOME/.initia/data ]; then mv $HOME/.initia/data/priv_validator_state.json $HOME/.initia/priv_validator_state.json rm -rf $HOME/.initia/data* $HOME/.initia/wasm* mkdir $HOME/.initia/data cp $HOME/.initia/priv_validator_state.json $HOME/.initia/data/priv_validator_state.json fi sudo systemctl start initiad FinYour node should now be syncing via statesync, using pebbleDB! Make sure to open up your firewall to allow incoming traffic on port 26656 as well to increase your peering.
