# Deploying Conduit

## Getting help

If you run into any problems while setting up Conduit, write an email to `support@conduit.rs`, ask us in `#conduit:matrix.org` or [open an issue on GitLab](https://gitlab.com/famedly/conduit/-/issues/new).

## Installing Conduit

You have to download the binary that fits your machine. Run `uname -m` to see
what you need. Now copy the right url:
- x84_64: `https://conduit.rs/master/x86_64/conduit-bin`
- armv7: `https://conduit.rs/master/armv7/conduit-bin`
- armv8: `https://conduit.rs/master/armv8/conduit-bin`
- arm: `https://conduit.rs/master/arm/conduit-bin`

```bash
$ sudo wget -O /usr/local/bin/conduit <url>
$ sudo chmod +x /usr/local/bin/conduit
```


## Setting up a systemd service

Now we'll set up a systemd service for Conduit, so it's easy to start/stop
Conduit and set it to autostart when your server reboots. Simply paste the
default systemd service you can find below into
`/etc/systemd/system/conduit.service`.

```systemd
[Unit]
Description=Conduit Matrix Server
After=network.target

[Service]
Environment="CONDUIT_CONFIG=/etc/matrix-conduit/conduit.toml"
User=root
Group=root
Restart=always
ExecStart=/usr/local/bin/matrix-conduit

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

Finally, run
```bash
$ sudo systemctl daemon-reload
```


## Creating the Conduit configuration file

Now we need to create the Conduit's config file in `/etc/matrix-conduit/conduit.toml`. Paste this in **and take a moment to read it. You need to change at least the server name.**
```toml
[global]
# The server_name is the name of this server. It is used as a suffix for user
# and room ids. Examples: matrix.org, conduit.rs
# The Conduit server needs to be reachable at https://your.server.name/ on port
# 443 (client-server) and 8448 (federation) OR you can create /.well-known
# files to redirect requests. See
# https://matrix.org/docs/spec/client_server/latest#get-well-known-matrix-client
# and https://matrix.org/docs/spec/server_server/r0.1.4#get-well-known-matrix-server
# for more information

# YOU NEED TO EDIT THIS
#server_name = "your.server.name"

# This is the only directory where Conduit will save its data
database_path = "/var/lib/matrix-conduit/conduit_db"

# The port Conduit will be running on. You need to set up a reverse proxy in
# your web server (e.g. apache or nginx), so all requests to /_matrix on port
# 443 and 8448 will be forwarded to the Conduit instance running on this port
port = 6167

# Max size for uploads
max_request_size = 20_000_000 # in bytes

# Disabling registration means no new users will be able to register on this server
allow_registration = false

# Disable encryption, so no new encrypted rooms can be created
# Note: existing rooms will continue to work
allow_encryption = true
allow_federation = true

#cache_capacity = 1073741824 # in bytes, 1024 * 1024 * 1024
#max_concurrent_requests = 4 # How many requests Conduit sends to other servers at the same time
#workers = 4 # default: cpu core count * 2

address = "127.0.0.1" # This makes sure Conduit can only be reached using the reverse proxy
```


## Setting up the Reverse Proxy

This depends on whether you use Apache, Nginx or another web server.

### Apache

Create `/etc/apache2/sites-enabled/050-conduit.conf` and copy-and-paste this:
```
Listen 8448

<VirtualHost *:443 *:8448>

ServerName your.server.name # EDIT THIS

AllowEncodedSlashes NoDecode
ProxyPass /_matrix/ http://localhost:6167/
ProxyPassReverse /_matrix/ http://localhost:6167/

Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateFile /etc/letsencrypt/live/your.server.name/fullchain.pem # EDIT THIS
SSLCertificateKeyFile /etc/letsencrypt/live/your.server.name/privkey.pem # EDIT THIS
</VirtualHost>
```

**You need to make some edits again.** When you are done, run
```bash
$ sudo systemctl reload apache2
```


### Nginx

If you use Nginx and not Apache, add the following server section inside the
http section of `/etc/nginx/nginx.conf`
```
server {
    listen 443;
    listen 8448;
    server_name your.server.name; # EDIT THIS

    location /_matrix/ {
        proxy_pass http://localhost:6167/_matrix/;
    }
}
```
**You need to make some edits again.** When you are done, run
```bash
$ sudo systemctl reload nginx
```


## SSL Certificate

The easiest way to get an SSL certificate, if you don't have one already, is to install `certbot` and run this:
```bash
$ sudo certbot -d your.server.name
```


## You're done!

Now you can start Conduit with:
```bash
$ sudo systemctl start conduit
```

Set it to start automatically when your system boots with:
```bash
$ sudo systemctl enable conduit
```
