# How to Deploy Sorada

## System Requirements

### Operating System

* Ubuntu Server 22.04 LTS

### Hardware Requirements

* CPU: 2-core
* RAM: 8GB
* SSD: 16GB

### Server Port Policy

* Open port 80 to support RPC external services.

## System Tuning

Optimize `sysctl` knobs

```bash
sudo bash -c "cat >/etc/sysctl.d/21-haproxy.conf <<EOF
# Increase system level number of allowed open file descriptors
fs.nr_open=1100000
fs.file-max=1100000

# Set tcp config
net.ipv4.ip_local_port_range=5000 65000
net.ipv4.tcp_syncookies = 1
net.core.somaxconn = 4096
EOF"

sudo sysctl -p /etc/sysctl.d/21-haproxy.conf
```

Increase `systemd` file limits

```bash
sudo mkdir /etc/systemd/system/haproxy.service.d
sudo bash -c "cat >/etc/systemd/system/haproxy.service.d/21-override.conf <<EOF
[Service]
# Increase user level number of hard limit and soft limit of file descriptors
LimitNOFILE=1000000
EOF"
sudo systemctl daemon-reload
sudo systemctl enable haproxy
```

### Install `HAProxy`

```bash
sudo apt-get install --no-install-recommends software-properties-common
sudo add-apt-repository ppa:vbernat/haproxy-3.0
sudo apt-get install haproxy=3.0.\*
```

## Configure Routing

Edit `/etc/haproxy/haproxy.cfg`, routing archival requests to archival RPC endpoint and other requests to HyperGrid.

```
    acl methodGetBlock req.body -m reg \"getBlock\"
    acl methodGetBlocks req.body -m reg \"getBlocks\"
    acl methodGetBlocksWithLimit req.body -m reg \"getBlocksWithLimit\"
    acl methodGetBlockTime req.body -m reg \"getBlockTime\"
    acl methodGetSigsForAddr req.body -m reg \"getSignaturesForAddress\"
    acl methodGetTransaction req.body -m reg \"getTransaction\"
    use_backend archival if methodGetBlock
    use_backend archival if methodGetBlocks
    use_backend archival if methodGetBlocksWithLimit
    use_backend archival if methodGetBlockTime
    use_backend archival if methodGetSigsForAddr
    use_backend archival if methodGetTransaction
    default_backend HyperGrid
```

## Start Service

```bash
systemctl start haproxy
```

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://docs.sonicsvm.org/architecture/sorada/how-to-deploy-sorada.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.
