# Osmosis Archive Node Setup

## Osmosisd

Installing the Osmosis Binary:

cd $HOME
git clone https://github.com/osmosis-labs/osmosis
cd osmosis
git checkout v11.0.1
make install

## Initialize Osmosis Node

#node name used : Validatus
osmosisd init Validatus

#Downloading and placing genesis in osmosis config:
wget -O ~/.osmosisd/config/genesis.json https://github.com/osmosis-labs/networks/raw/main/osmosis-1/genesis.json

## Install and setup Cosmovisor

cd $HOME
git clone https://github.com/cosmos/cosmos-sdk
cd cosmos-sdk
git checkout v0.42.5
make cosmovisor
cp cosmovisor/cosmovisor $GOPATH/bin/cosmovisor
cd $HOME

Now make the necessary directories:

mkdir -p ~/.osmosisd
mkdir -p ~/.osmosisd/cosmovisor
mkdir -p ~/.osmosisd/cosmovisor/genesis
mkdir -p ~/.osmosisd/cosmovisor/genesis/bin
mkdir -p ~/.osmosisd/cosmovisor/upgrades

Next, set the following Environment Variables for Cosmovisor:

sudo tee -a /etc/profile << END
#cosmovisor
export DAEMON_NAME=osmosisd
export DAEMON_HOME=\$HOME/.osmosisd
export PATH=\$PATH:\$DAEMON_HOME/cosmovisor/current/bin
END
source /etc/profile

Copy osmosisd binary into the cosmovisor/genesis folder:

cp $GOPATH/bin/osmosisd ~/.osmosisd/cosmovisor/genesis/bin

Check versions of Cosmovisor and Osmosisd:

cosmovisor version
osmosisd version

Next, add a clean address book:

wget -O - https://quicksync.io/addrbook.osmosis.json > $HOME/.osmosisd/config/addrbook.json

## Download Chain Data

Download lz4:

sudo dnf install lz4

Now download the archive node chain data:

URL=`curl -L https://quicksync.io/osmosis.json|jq -r '.[] |select(.file=="osmosis-1-archive")|select (.mirror=="Netherlands")|.url'`
wget -O - $URL | lz4 -d | tar -xvf -

## Changes in config.toml/app.toml
### app.toml
As the node will be archive node, change the necessary options in app.toml, as shown:

Set API address/port, as follows:

Set port for grpc, as shown:

### config.toml
Set proxy_app address and port, as shown:

Change the database data location to the OpenZFS drive:

Set RPC laddr to the following:

Set pprof_laddr:

Next, set P2P laddr:

Now set the max. inbound/outbound connections:

## Setup systemd service

Now move the cosmovisor.service file to:

sudo mv cosmovisor.service /lib/systemd/system/cosmovisor.service

Reload and start the service:

sudo systemctl daemon-reload
sudo systemctl restart systemd-journald
sudo systemctl start cosmovisor

#To check  status
sudo systemctl status cosmovisor
sudo journalctl -xe
