# Installation

## Server preparation

```shell
apt update && apt upgrade -y
```

```shell
apt install curl iptables build-essential git wget jq make gcc nano tmux htop nvme-cli pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev -y
```

#### Install GO

```shell
ver="1.19.1"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version
```

## Node installation

```shell
git clone https://github.com/alpha-omega-labs/genesis-crypto && cd genesis-crypto
git checkout v1.0.0
make install

genesisd version --long
# 1.0.0
# commit: 7cb02ad35442e00b7eb24dc06868577223d48141
```

#### We initialize the node to create the necessary configuration files

<pre class="language-shell"><code class="lang-shell"><strong>genesisd init UTSA_guide --chain-id genesis_29-2
</strong></code></pre>

#### Download Genesis

```shell
wget -O $HOME/.genesisd/config/genesis.json "https://github.com/alpha-omega-labs/genesisd/raw/neolithic/genesis_29-1-state/genesis.json"

# Проверим генезис
sha256sum ~/.genesisd/config/genesis.json
# b8f6939f3bfaeec666c7efb94a683e9295e40705ef08af14d55014e4fa11757f
```

#### At this stage, we can download the address book

```shell
wget -O $HOME/.genesisd/config/addrbook.json "https://anode.team/GenesisL1/main/addrbook.json"
```

#### Set up node configuration

```shell
genesisd config chain-id genesis_29-2
genesisd config keyring-backend os
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.0025el1\"/;" ~/.genesisd/config/app.toml
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.genesisd/config/config.toml
peers=""
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.genesisd/config/config.toml
seeds=""
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.genesisd/config/config.toml
sed -i 's/max_num_inbound_peers =.*/max_num_inbound_peers = 50/g' $HOME/.genesisd/config/config.toml
sed -i 's/max_num_outbound_peers =.*/max_num_outbound_peers = 50/g' $HOME/.genesisd/config/config.toml
sed -i -e "s/^filter_peers *=.*/filter_peers = \"true\"/" $HOME/.genesisd/config/config.toml
# if necessary, disable JSON RPC Configuration in app.toml 
# nano /root/.genesisd/config/app.toml
# enable = false
# Proposal https://ping.pub/genesisl1/gov/55
sed -i -e "s/^timeout_commit *=.*/timeout_commit = \"10s\"/" $HOME/.genesisd/config/config.toml
```

#### (OPTIONAL) Set up pruning

```shell
pruning="custom"
pruning_keep_recent="1000"
pruning_keep_every="0"
pruning_interval="50"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.genesisd/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.genesisd/config/app.toml 
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.genesisd/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.genesisd/config/app.toml
```

#### (OPTIONAL) Set up indexer

```shell
indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.genesisd/config/config.toml
```

#### (OPTIONAL) Enable/Disable Snapshots

```shell
snapshot_interval=1000
sed -i.bak -e "s/^snapshot-interval *=.*/snapshot-interval = \"$snapshot_interval\"/" ~/.genesisd/config/app.toml
```

#### Create a service file

```shell
sudo tee /etc/systemd/system/genesisd.service > /dev/null <<EOF
[Unit]
Description=genesisd
After=network-online.target

[Service]
User=$USER
ExecStart=$(which genesisd) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF
```

```shell
systemctl daemon-reload
systemctl enable genesisd
systemctl restart genesisd && journalctl -u genesisd -f -o cat
```

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://utsa.gitbook.io/services/mainnet/genesis-l1/installation.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
