Nexus Final Testnet Preparations and Setup Guide

Many people frequently ask in the chat: how, why, what, how to solve a certain problem, why the node crashes — there are indeed many such questions. There's simply not enough hands to answer everyone, so I decided to compile everything into one post. 🖤 Reminder! Nexus launched the final phase of its testnet a few days ago, which will last until the main network launch — which is at least a few weeks away. 🖤 System requirements for the node: 🟣 Recommended — 4 cores, 16 GB RAM 🟣 Minimum — 2 cores, 6 GB RAM + mandatory 10 GB swap 🟣 The node crashes without a swap file. 🖤 Setting up a swap file (mandatory with 6 GB RAM): sudo dd if=/dev/zero of=/swapfile bs=1M count=10240 && \ sudo chmod 600 /swapfile && \ sudo mkswap /swapfile && \ sudo swapon /swapfile && \ echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab 🖤 Running multiple proofers (if you have a powerful server): 🟣 Add the --max-threads flag (maximum — 8): docker run -it --init --name nexus nexusxyz/nexus-cli:latest start \ --node-id YOUR_ID --max-threads NUMBER_OF_THREADS 🟣 Example for 6 proofers: --max-threads 6 🖤 Restarting the node: screen -r nexus3 docker stop nexus docker rm nexus docker start nexus 🖤 Errors and failures: 🟣 504, 422, and others — are Nexus bugs. 🟣 The only reason for crashes is insufficient RAM, which can be fixed with a swap file. 🖤 Updating to the latest version: docker stop nexus docker rm nexus docker pull nexusxyz/nexus-cli:latest screen -r nexus3 docker run -it --init --name nexus nexusxyz/nexus-cli:latest start \ --node-id YOUR_ID --max-threads NUMBER_OF_THREADS 🖤 Text guide with all instructions 🖤 Video guide with all instructions 🖤 Easier option: 🖤 If you want to get involved in the node sphere without spam and unnecessary information noise, welcome to Forto Club.
