• OS Ubuntu 20.04
• Hosts
  • ethereum_nodes (8CPU, 32RAM, 1,5Tb)
  • validators_ejector (1CPU, 8RAM, 50Gb)
  • monitoring_server (2CPU, 8RAM, 50Gb)

Also, we recommend having a data of nodes and system on different volumes. In other words /srv should be a separate volume

1. First of all, you need - to get three servers.

   • Host for geth and lighthouse nodes
   • Host for validator-ejector and keys-api services
   • Host for monitoring system alert-box

2. Prepare conf file

   • Login to monitoring_server
   • Download conf file to monitoring server - Run command curl https://raw.githubusercontent.com/lidofinance/node-operators-setup/master/variables --output variables
   • Fill out conf variables in file variables
     • ETHEREUM_NODES_IP - IP address of your ethereum_nodes host
     • VALIDATORS_EJECTOR_IP - IP address of your validators_ejector host
     • MONITORING_SERVER_IP - IP address of your monitoring_server host
     • ENVIRONMENT - Environment of setup (testnet or mainnet)
     • TELEGRAM_BOT_TOKEN - Token of your telegram bot
     • TELEGRAM_CHAT_ID - chat_id of your channel for alerts
     • VALIDATOR_EJECTOR_MESSAGES_PASSWORD - your messages password

3. Run installation

   • Login to monitoring_server
   • Run command curl -L https://raw.githubusercontent.com/lidofinance/node-operators-setup/master/base.sh | bash -s

4. After successful installation, you can find your grafana credentials in file secret_variables, the same directory you had ran your script base.sh Enter the IP address of your monitoring server to a browser and enter the login and password for grafana.

5. To upgrade your installation, just run the command again curl -L https://raw.githubusercontent.com/lidofinance/node-operators-setup/master/base.sh | bash -s

In case you want use your self login and password for grafana and internal database you should create file with next values

secret_variables file contents

    ALERTS_BOX_GRAFANA_USER=<your_grafana_username>
    ALERTS_BOX_GRAFANA_PASSWORD=<your_grafana_password>
    LIDO_KEYS_API_DB_PASSWORD=<your_database_password>

The file secret_variables must be created before running base.sh

• Add additional dashboards
• Tests
• Mount extra disks
• Remove extra variables from logs block
