### 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:
|
||
|
|
