## Quick Start
|
|
|
|
### Prerequisites
|
|
|
|
- Docker or Docker Compose installed on your system
|
|
- Minimum 512MB RAM and 1GB available disk space
|
|
|
|
### Docker Deployment
|
|
|
|
Deploy Memos in production mode using Docker:
|
|
|
|
```bash
|
|
# Create data directory
|
|
mkdir -p ~/.memos
|
|
|
|
# Run Memos container
|
|
docker run -d \
|
|
--name memos \
|
|
--restart unless-stopped \
|
|
-p 5230:5230 \
|
|
-v ~/.memos:/var/opt/memos \
|
|
neosmemo/memos:stable
|
|
```
|
|
|
|
Access the application at `http://localhost:5230` and complete the initial setup process.
|
|
|
|
### Docker Compose Deployment
|
|
|
|
For advanced configurations, use Docker Compose:
|
|
|
|
```yaml
|
|
# docker-compose.yml
|
|
version: "3.8"
|
|
services:
|
|
memos:
|
|
image: neosmemo/memos:stable
|
|
container_name: memos
|
|
restart: unless-stopped
|
|
ports:
|
|
- "5230:5230"
|
|
volumes:
|
|
- ./data:/var/opt/memos
|
|
environment:
|
|
- MEMOS_MODE=prod
|
|
- MEMOS_PORT=5230
|
|
```
|
|
|
|
Deploy with:
|
|
|
|
```bash
|
|
docker-compose up -d
|
|
```
|
|
|
|
> **Note**: The data directory (`~/.memos/` or `./data/`) stores all application data including the database, uploaded files, and configuration. Ensure this directory is included in your backup strategy.
|
|
