There are two main ways to get started with mCaptcha:
### Tutorial

## Requirements
Doks uses npm to install dependencies and run commands. Installing npm is pretty simple. Download and install [Node.js](https://nodejs.org/) (it includes npm) for your platform.
## Start a new Doks project
Create a new site, change directories, install dependencies, and start development server.
### Create a new site
{{< btn-copy text="git clone https://github.com/h-enk/doks.git my-doks-site" >}}
```bash
git clone https://github.com/h-enk/doks.git my-doks-site
```
### Change directories
{{< btn-copy text="cd my-doks-site" >}}
```bash
cd my-doks-site
```
### Install dependencies
{{< btn-copy text="npm install" >}}
```bash
npm install
```
### Start development server
{{< btn-copy text="npm run start" >}}
```bash
npm run start
```
Doks will start the Hugo development webserver accessible by default at `http://localhost:1313`. Saved changes will live reload in the browser.
## Other commands
Doks comes with commands for common tasks. [Commands →]({{< ref "commands" >}})

### 2. Configure
mcaptcha is highly configurable.
Configuration is applied/merged in the following order:
1. path to configuration file passed in via `MCAPTCHA_CONFIG`
2. `./config/default.toml`
3. `/etc/mcaptcha/config.toml`
4. environment variables.
### 1. Install postgres if you don't have it already.
For Debian based distributions:
```bash
sudo apt install postgres
```
### 2. Create new user for running `mcaptcha`
```bash
$ sudo useradd -b /srv -m -s /usr/bin/zsh mcaptcha
```
### 3. Create new user in Postgres
```bash
$ sudo -iu postgres # switch to `postgres` user
$ psql
postgres=# CREATE USER mcaptcha WITH PASSWORD 'my super long password and yes you need single quote`;
$ createdb -O mcaptcha mcaptcha # create db 'mcaptcha' with 'mcaptcha' as owner
```
### 4. Install and load [`mCaptcha/cache`](https://github.com/mCaptcha/cache) module:
See [`mCaptcha/cache`](https://github.com/mCaptcha/cache) for more
details.
### 4. Build `mcaptcha`
To build `mcaptcha`, you need the following dependencies:
1. rust
2. node(`v14.16.0`)
3. yarn(JavaScript package manager)
4. make
## How to build
1. Install Cargo using [rustup](https://rustup.rs/) with:
```bash
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
2. Install node(`v14.16.0`)
3. Install yarn(JavaScript package manager)
4. Build with make:
```bash
$ make dev-env && \
make release
```
### 5. Install package:
```bash
$ sudo cp ./target/release/mcaptcha /usr/bin/ && \
mkdir sudo /etc/mcaptcha && \
sudo cp config/default.toml /etc/mcaptcha/config.toml
```
### 6. Systemd service configuration:
1. Copy the following to `/etc/systemd/system/mcaptcha.service`:
```systemd
[Unit]
Description=mCaptcha: a CAPTCHA system that gives attackers a run for their money
[Service]
Type=simple
User=mcaptcha
ExecStart=/usr/bin/mcaptcha
Restart=on-failure
RestartSec=1
SuccessExitStatus=3 4
RestartForceExitStatus=3 4
SystemCallArchitectures=native
MemoryDenyWriteExecute=true
NoNewPrivileges=true
Environment="RUST_LOG=info"
[Unit]
After=sound.target
Wants=network-online.target
Wants=network-online.target
Requires=postgresql.service
After=syslog.target
[Install]
WantedBy=multi-user.target
```
2. Enable service:
```bash
$ sudo systemctl daemon-reload && \
sudo systemctl enable mcaptcha && \ # Auto startup during boot
sudo systemctl start mcaptcha
``
```

## Notes
### Database
- Database migrations are baked into the server binary so don't worry
about them.
- When compiling from source, unset database configuration(comment out
database configuration/ `unset` relevant environment variables).
`mCaptcha` uses [`sqlx`](https://crates.io/crates/sqlx) database client
library which checks SQL queries at compile time. So if you are starting
with a fresh database without migrations applied, compilation will fail.
### Redis
- Redis is an optional dependency. Currently, the non-Redis configuration
doesn't persist CAPTCHA heat. So if there's a systems failure, CAPTCHA
heat will be reset and visitor count will start from 0. For small
installations, this should post a problem as heat is short lived and is
reset anyways at cool down period.
- mCaptcha uses a custom Redis module called
[cache](https://github.com/mCaptcha/cache) to overcome some of Redis'
limitations.
## Instructions
Once again, there are two ways to go about this:
1. Docker
2. Bare metal
### Docker
### Database
Download and run Postgres
```bash
docker create --name mcaptcha-postgres \
-e POSTGRES_PASSWORD=<databse-password> \
-p 5432:5432 \
postgres && docker start mcaptcha-postgres
```
### Redis
```bash
docker create --name mcaptcha-cache \
-p 6379:6379 \
mcaptcha/cache && docker start mcaptcha-cache
```
See [mCaptcha/cache](https://github.com/mCaptcha/cache) for more
details.
### 1. Install Postgres if you don't have it already.
For Debian based distributions:
```bash
sudo apt install postgres
```
### 2. Create new user for running `mCaptcha`
```bash
$ sudo useradd -b /srv -m -s /usr/bin/bash mcaptcha
```
### 3. Create new user in Postgres
```bash
$ sudo -iu postgres # switch to `postgres` user
$ psql
postgres=# CREATE USER mcaptcha WITH PASSWORD 'my super long password and yes you need single quote';
$ createdb -O mcaptcha mcaptcha # create db 'mcaptcha' with 'mcaptcha' as owner
```
### 4. Install [`mCaptcha/cache`](https://github.com/mCaptcha/cache)
See [`mCaptcha/cache`](https://github.com/mCaptcha/cache) for more
details.

## Docker
### 1. Configure
mcaptcha is highly configurable.
Configuration is applied/merged in the following order:
1. path to configuration file passed in via `MCAPTCHA_CONFIG`
2. `./config/default.toml`
3. `/etc/mcaptcha/config.toml`
4. environment variables.
See
[CONFIGURATION.md](https://github.com/mCaptcha/mCaptcha/tree/master/docs/CONFIGURATION.md)
for configurable options.
### 2. Run image
If you have already have a Postgres instance running, then:
```bash
docker run -p <host-machine-port>:<port-in-configuration-file> \
--add-host=database:<database-ip-addrss> \
-e RUST_LOG=debug \
-e DATABASE_URL="postgres://<db-user>:<db-password>@database:<db-port>/<db-name>" \
mcaptcha/mcaptcha:latest
```
If you don't have a Postgres instance running, you can either install
one using a package manager or launch one with docker. A [docker-compose
configuration]('../docker-compose.yml) is available that will launch both
a database instance mcaptcha instance.
## With docker-compose
1. Follow steps above to build docker image.
2. Set database password [docker-compose configuration]('../docker-compose.yml).
3. Launch network
```bash
docker-compose up -d
```
