# Instructions to Run Full Node
Hardware
---
#### Supported
- **Operating System (OS):** Ubuntu 20.04
- **CPU:** 1 core
- **RAM:** 2GB
- **Storage:** 25GB SSD
#### Recommended
- **Operating System (OS):** Ubuntu 20.04
- **CPU:** 2 core
- **RAM:** 4GB
- **Storage:** 50GB SSD
# A) Setup
## 1) Install Golang (go)
1.1) Remove any existing installation of `go`
```
sudo rm -rf /usr/local/go
```
1.2) Install latest/required Go version (installing `go1.17.2`)
```
curl https://golang.org/dl/go1.17.2.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz
```
1.3) Update env variables to include `go`
```
cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source $HOME/.profile
```
1.4) Check the version of go installed
```
go version
```
### 2) Install required software packages
```
sudo apt-get install git curl build-essential make jq -y
```
### 3) Install `chibaclonkd`
```
git clone https://github.com/vulcanize/chiba-clonk.git
cd chiba-clonk
git fetch --all
git checkout main
make install
```
### 4) Verify your installation
```
chibaclonkd version --long
```
On running the above command, you should see a similar response like this. Make sure that the *version* and *commit
hash* are accurate
```
name: chibaclonkd
server_name: chibaclonkd
```
### 5) Initialize Node
**Not required if you have already initialized before**
```
chibaclonkd init <your-node-moniker> --chain-id chibaclonk_81337-1
```
On running the above command, node will be initialized with default configuration. (config files will be saved in node's
default home directory (~/.chibaclonkd/config)
NOTE: Backup node and validator keys . You will need to use these keys at a later point in time.

# B) Starting Node
## 1) Download Final Genesis
Use `curl` to download the genesis file
**Replace your **genesis** file with published genesis file**
```shell
2022-04-06 01:56:51 +00:00
# Will be updated
curl {GENESIS_LINK} | jq .result.genesis > ~/.chibaclonkd/config/genesis.json
2022-04-06 01:28:21 +00:00
```
Verify sha256 hash of genesis file with the below command
```
jq -S -c -M '' ~/.chibaclonkd/config/genesis.json | shasum -a 256
```
genesis sha256 hash should be
```
2022-04-06 01:56:51 +00:00
{WILL BE UPDATED}
2022-04-06 01:28:21 +00:00
```
## 2) Update Peers & Seeds in config.toml
```
2022-04-06 01:56:51 +00:00
<!-- Note: don't use peers
peers="5ad2e6c35f2c84ff3ee31d89a95b34d92cb6afb1@157.230.101.237:26656,defc95b08547b6ef254723ad9621967a7e819020@161.35.223.44:26656" -->
{peers={WILL BE UPDATED}}
2022-04-06 01:28:21 +00:00
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.chibaclonkd/config/config.toml
```
## 3) Start the Full Node
#### 3.1) Start node as `systemctl` service
3.1.1) Create the service file
```
sudo tee /etc/systemd/system/chibaclonkd.service > /dev/null <<EOF
[Unit]
Description=chibaclonkd Daemon
After=network-online.target
[Service]
User=$USER
ExecStart=$(which chibaclonkd) start --gql-playground --gql-server
Restart=always
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF
```
3.1.2) Load service and start
```
sudo systemctl daemon-reload
sudo systemctl enable chibaclonkd
sudo systemctl start chibaclonkd
```
3.1.3) Check status of service
```
sudo systemctl status chibaclonkd
```
`NOTE:`
A helpful command here is `journalctl` that can be used to:
a) check logs
```
journalctl -u chibaclonkd
```
b) most recent logs
```
journalctl -xeu chibaclonkd
```
c) logs from previous day
```
journalctl --since "1 day ago" -u chibaclonkd
```
d) Check logs with follow flag
```
journalctl -f -u chibaclonkd
```
