Terraform-Validator-03: Create Full Node

2021-04-09

SPECIAL NOTICE: TERRA HAS FALLEN

Whether this machine is a Validator or just a sentry, the setup is mostly common.

Create terrauser

sudo useradd terrauser

Update OS and add a few packages

sudo yum update -y
sudo yum install jq git wget make gcc -y

Adjust nofiles kernel param

sudo bash -c "cat > /etc/security/limits.d/terrad.conf << EOF
# /etc/security/limits.conf

*                soft    nofile          65535
*                hard    nofile          65535
EOF"

Install go

wget https://golang.org/dl/go1.16.3.linux-amd64.tar.gz -O - | tar xz 
sudo mv go /usr/local
export PATH=/usr/local/go/bin:$PATH
echo "export PATH=/usr/local/go/bin:$PATH" >> /home/terrauser/.bashrc

Install terrad

git clone https://github.com/terra-project/core.git
pushd core
PATH=$PATH:/usr/local/go/bin GOBIN=$(pwd)/bin make install
sudo mv bin/terra* /usr/local/bin
popd

Install terrad’s systemd unit file

sudo bash -c "cat > /etc/systemd/system/terrad.service << EOF
[Unit]
Description=Terra Daemon
After=network.target

[Service]
Type=simple
User=terrauser
ExecStart=/usr/local/bin/terrad start
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

[Service]
LimitNOFILE=65535
EOF"

Install a systemd unit file for LCD as well

sudo bash -c "cat > /etc/systemd/system/lcd.service << EOF
[Unit]
Description=Terra CLI LCD Service
After=network.target

[Service]
Type=simple
User=terrauser
ExecStart=/usr/local/bin/terracli rest-server --chain-id=$NETWORK --laddr=tcp://0.0.0.0:1317 --node tcp://localhost:26657 --trust-node=true
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

[Service]
LimitNOFILE=65535
EOF"
  • NETWORK: tequila-0004, columbus-4, etc

Prepare daemons for launch

sudo systemctl daemon-reload
sudo systemctl enable terrad
sudo systemctl enable lcd

Mount attached disk

It is no fun to catch up to the chain from scratch. You should have already downloaded latest chain and attached a disk with it to this instance.

sudo mkdir /terradata
sudo mount -t ext4 /dev/sdb /terradata
sudo chown -R terrauser:terrauser /terradata
