Whenever you see gaia or gaiad used make sure to replace with whatever node you are installing. Both app.toml and config.toml have been heavily commented with useful information. Please read through both of these files carefully.
Direct yourself to your node's configuation folder.
cd ~/.gaiad/config/
Set your preferred pruning settings. Here is an example set of commands to run while located inside your config directory. Update values to your preference and space needs (the numbers below are for tight pruning). If you ever find your chain data is taking up too much space, consider using tools such as cosmprund. If you are running an archive node then you can ignore this, otherwise edit values as you need and copy/paste the following into your terminal:
pruning="custom" && \
pruning_keep_recent=107 && \
pruning_keep_every=0 && \
pruning_interval=73 && \
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" app.toml && \
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" app.toml && \
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" app.toml && \
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" app.toml
It's time to edit app.toml if you need to enable, disable, or edit ports for API and gRPC. Also be mindful of minimum gas fees, especially if you are a valiadtor. Refer to official docs for more information. To get started open the app.toml file.
nano ~/.gaia/config/app.toml
CTRL+X and save any changes you made.
Direct yourself to your node's configuation folder.
cd ~/.gaiad/config/
nano config.toml
This is the main configuration file for your node. If you are using default ports there is not much that needs changed here. If you are using custom ports, be sure to edit them here and verify UFW settings before launching your node.
If you wish to access your node remotely from a local machine, you'll also need to expose the node's RPC by changing the IP address to 0.0.0.0 in the RPC section
# TCP or UNIX socket address for the RPC server to listen on
laddr = "tcp://0.0.0.0:26657"
You'll also need to add peers before you start syncing. Most blockchains will have a network repository featuring peer lists, genesis files, etc., Another great option is to use Polkachu if they have the chain resources available on their website. You can find resources for state sync, snapshot sync, peers, etc.,
When adding seeds or peers, make they are placed inbetween quotes, divided by commas with no spaces. For example:
seeds = ade4d8bc8cbe014af6ebdf3cb7b1e9ad36f412c0@seeds.polkachu.com:14956"
persistent_peers = "cf10a45ead9e76d45b06dee97ef779e65103c78e@3.128.185.235:26656,91d50a7faf28fe301085f340a7d98a518e1243bd@44.236.220.165:26656"
The best practice for peering is to avoid adding persistent peers you do not know personally. Having a few solid seed nodes instead should be enough to build up a solid address book. This means you could technically run a stable node without any persistent peers. Trust the system.
After you are done editing config.toml be sure to press CTRL+X and save any changes you made.
You are now ready to sync your node
