# Running a main network node **1/ Initialize your node** Replace `` by the node name of your choice ``` $ lumd init --chain-id lum-network-1 ``` **2/ Edit the config files** ``` $ nano ~/.lumd/config/config.toml ``` Search for "seed\_peers" and replace the value as following: ``` seeds = "19ad16527c98b782ee35df56b65a3a251bd99971@peer-1.mainnet.lum.network:26656" ``` Once opened, search for "persistent\_peers" and replace the value as following: ``` persistent_peers = "b47626b9d78ed7ed3c413304387026f907c70cbe@peer-0.mainnet.lum.network:26656,5ea36d78ae774c9086c2d3fc8b91f12aa4bf3029@46.101.251.76:26656,a7f8832cb8842f9fb118122354fff22d3051fb83@3.36.179.104:26656,9afac13ba62fbfaf8d06867c30007162511093c0@54.214.134.223:26656,433c60a5bc0a693484b7af26208922b84773117e@34.209.132.0:26656,8fafab32895a31a0d7f17de58eddb492c6ced6d1@185.194.219.83:36656,c06eae3d9ea779710bca44e03f57e961b59d63f1@82.65.223.126:46656,4166de0e7721b6eec9c776abf2c38c40e7f820c5@202.61.239.130:26656,5a29947212a2615e43dac54deb55356a162e173a@35.181.76.160:26656,2cda4d97de0449878da10e456b176dd0720fbcec@62.171.129.174:26656" ``` Get the genesis file and put it in \~/.lumd/config/genesis.json (you can replace it if one was generated automatically) and double check the sha256sum. ``` $ curl -s https://raw.githubusercontent.com/lum-network/mainnet/master/genesis.json > ~/.lumd/config/genesis.json $ sha256sum ~/.lumd/config/genesis.json 3bbbd7aff6c545126d869fc683f6344e65ae71b048b25540826cd2f3be91a24c ``` **2-bis/ Synchronize from latest up-to-date state machine** You are offered a possibility to avoid syncing every single code / state machine upgrade by using ChainLayer's QuickSync service. You can find relevant URLs and hashes here: Different versions are available: * Pruned: lightweight version of the state machine, only contains recent blocks / transactions in full * Default: standard version of the state machine When using the commands provided by QuickSync, please make sure that you edit the relevant paths and other configuration according to your setup. **3/ Start your node** ``` $ lumd start ``` You will now notice that the node starts to sync the blockchain history. **But,** as soon as you quit the SSH screen or close the window, you will kill it. To avoid doing this launch it in a daemon process: ``` $ sudo nano /etc/systemd/system/lumd.service ``` Copy and paste the following and update ``: ``` [Unit] Description=Lum Network daemon After=network-online.target [Service] User=lum ExecStart=//go/bin/lumd start --p2p.laddr tcp://0.0.0.0:26656 --home //.lumd Restart=on-failure RestartSec=3 LimitNOFILE=4096 [Install] WantedBy=multi-user.target ``` Enable and start the new service: ``` $ sudo systemctl enable lumd $ sudo systemctl start lumd ``` Check your node status: ``` $ lumd status ``` Check your node logs: ``` $ journalctl -u lumd -f ```
