# 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 `laconicd`
|
|
|
|
```
|
|
git clone https://github.com/cerc-io/laconicd.git
|
|
cd laconicd
|
|
git fetch --all
|
|
git checkout main
|
|
make install
|
|
```
|
|
|
|
### 4) Verify your installation
|
|
|
|
```
|
|
laconicd 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: laconicd
|
|
server_name: laconicd
|
|
```
|
|
|
|
### 5) Initialize Node
|
|
|
|
**Not required if you have already initialized before**
|
|
|
|
```
|
|
laconicd init <your-node-moniker> --chain-id laconic_81337-2
|
|
```
|
|
|
|
On running the above command, node will be initialized with default configuration. (config files will be saved in node's
|
|
default home directory (~/.laconicd/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
|
|
# Will be updated
|
|
curl {GENESIS_LINK} | jq .result.genesis > ~/.laconicd/config/genesis.json
|
|
```
|
|
|
|
Verify sha256 hash of genesis file with the below command
|
|
|
|
```
|
|
jq -S -c -M '' ~/.laconicd/config/genesis.json | shasum -a 256
|
|
```
|
|
|
|
genesis sha256 hash should be
|
|
|
|
```
|
|
{WILL BE UPDATED}
|
|
```
|
|
|
|
## 2) Update Peers & Seeds in config.toml
|
|
|
|
```
|
|
<!-- Note: don't use peers
|
|
peers="5ad2e6c35f2c84ff3ee31d89a95b34d92cb6afb1@157.230.101.237:26656,defc95b08547b6ef254723ad9621967a7e819020@161.35.223.44:26656" -->
|
|
|
|
{peers={WILL BE UPDATED}}
|
|
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.laconicd/config/config.toml
|
|
```
|
|
|
|
## 3) Start the Full Node
|
|
|
|
#### 3.1) Start node as `systemctl` service
|
|
|
|
3.1.1) Create the service file
|
|
|
|
```
|
|
sudo tee /etc/systemd/system/laconicd.service > /dev/null <<EOF
|
|
[Unit]
|
|
Description=laconicd Daemon
|
|
After=network-online.target
|
|
|
|
[Service]
|
|
User=$USER
|
|
ExecStart=$(which laconicd) 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 laconicd
|
|
sudo systemctl start laconicd
|
|
|
|
```
|
|
|
|
3.1.3) Check status of service
|
|
|
|
```
|
|
|
|
sudo systemctl status laconicd
|
|
|
|
```
|
|
|
|
`NOTE:`
|
|
A helpful command here is `journalctl` that can be used to:
|
|
|
|
a) check logs
|
|
|
|
```
|
|
|
|
journalctl -u laconicd
|
|
|
|
```
|
|
|
|
b) most recent logs
|
|
|
|
```
|
|
|
|
journalctl -xeu laconicd
|
|
|
|
```
|
|
|
|
c) logs from previous day
|
|
|
|
```
|
|
|
|
journalctl --since "1 day ago" -u laconicd
|
|
|
|
```
|
|
|
|
d) Check logs with follow flag
|
|
|
|
```
|
|
|
|
journalctl -f -u laconicd
|
|
|
|
```
