# Update Node to 9.1.1 > UPDATED: 9/5/2024 | Binaries | Version | Mainnet | | -------- | ------- | ------- | | Node | 9.1.1 | ✅ | | CLI | 9.2.1.0 | ✅ | {% hint style="info" %} Credits to [Earn Coin Pool](https://earncoinpool.com/) for documenting the procedure. {% endhint %} {% hint style="danger" %} Please note after updating it will take up to 6 hours maybe more to sync block replay. {% endhint %} ## Step 1 - GHC and Cabal Check Make sure you are using ghc 8.10.7 and cabal 3.8.1.0. If already installed you can skip this step. ``` ghcup upgrade ghcup install ghc 8.10.7 ghcup set ghc 8.10.7 ghcup install cabal 3.8.1.0 ghcup set cabal 3.8.1.0 ghc --version cabal --version ``` ## Step 2 - Backup your Configuration file: ``` cd $NODE_HOME cp mainnet-config.json mainnet-config.bak mv mainnet-conway-genesis.json mainnet-conway-genesis.bak ``` ## Step 3 - Download the new mainnet conway genesis file: ``` cd $NODE_HOME wget https://book.play.dev.cardano.org/environments/mainnet/conway-genesis.json mv conway-genesis.json mainnet-conway-genesis.json ``` ## Step 4 - Update Config file: ``` cd $NODE_HOME nano mainnet-config.json ``` Edit or add THESE TWO LINES to the following: ``` "ConwayGenesisFile": "mainnet-conway-genesis.json", "ConwayGenesisHash": "15a199f895e461ec0ffc6dd4e4028af28a492ab4e806d39cb674c88f7643ef62", ``` ## Step 5 - Download latest cardano-node git and checkout latest branch ``` cd $HOME/git git clone https://github.com/IntersectMBO/cardano-node.git cardano-node2 cd cardano-node2/ cabal update git fetch --all --recurse-submodules --tags git checkout tags/9.1.1 ``` ## Step 6 - Build the node If you have tmux, it is recommended to open tmux by typing `tmux` this will allow to run these commands to build the node without terminal timing out. ``` cd $HOME/git/cardano-node2 cabal configure -O0 -w ghc-8.10.7 cabal build cardano-node ``` ## Step 7 - Check cardano-node that the build was successful ``` $(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-node") version ``` ✅if 9.1.1 - move to next step ## Step 8 - Download latest cardano-cli git and checkout latest branch ``` cd $HOME/git/cardano-node2/ git clone https://github.com/IntersectMBO/cardano-cli.git cardano-cli cd cardano-cli/ cabal update git fetch --all --recurse-submodules --tags git checkout tags/cardano-cli-9.2.1.0 ``` ## Step 9 - Build the CLI ``` cd $HOME/git/cardano-node2/cardano-cli cabal configure -O0 -w ghc-8.10.7 cabal build cardano-cli ``` ## Step 10 - Check cardano-cli build was successful ``` $(find $HOME/git/cardano-node2/cardano-cli -type f -name "cardano-cli") version ``` ✅if 9.2.1.0 - and you were using tmux, close tmux by typing `exit` ## Step 11 - Shut down the node and move the binaries to your bin If on 9.1.1 node and 9.2.1.0 cli, then shut down the node and move the binaries to your bin ``` sudo systemctl stop cardano-node ``` ``` sudo cp $(find $HOME/git/cardano-node2/cardano-cli/dist-newstyle/build -type f -name "cardano-cli") /usr/local/bin/cardano-cli sudo cp $(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-node") /usr/local/bin/cardano-node ``` ## Step 12 - Check that successful version upgrades then start back up Cardano node ``` cardano-node version cardano-cli version ``` ✅If on 9.1.1 node and 9.2.1.0 cli move to next step ## Step 13 - Update and restart your instance ``` sudo apt-get update && sudo apt-get upgrade -y && sudo reboot ``` {% hint style="success" %} Block replay will now start after reboot. This could take up to 6 hours. To check progress run:\ `journalctl -fu cardano-node`\ \ Use Ctrl+C command to exit the real time view. {% endhint %} ## Step 14 - Clean up ``` cd $HOME/git/ rm -rf cardano-node-old mv cardano-node cardano-node-old mv cardano-node2 cardano-node ``` ## Additional Steps Copy the cardano-cli binaries to your air gap machine. You can copy from your /usr/local/bin or from the new build to a USB drive Check to see if you need to update other programs like CNCLI\ ### Congratulations you did it! ### Additional Resources: {% embed url="" %} {% endembed %} {% embed url="" %} {% endembed %} {% embed url="" %} {% endembed %} ## Contributors Thanks to the following pools for helping to put together these guides.
