## Installation
You need to SSH into your server as root and run the following command:
mkdir /app ;
cd /app/ || exit ;
git clone https://github.com/Polygant/OpenCEX.git ./deploy ;
cd deploy ;
chmod +x opencex.sh ;
./opencex.sh 2>&1 | tee /tmp/install.txt
Installation time ~ 5 minutes.
If something goes wrong you can clean the installation and try again
cd /app/opencex && docker compose down ;
rm -rf /app ;
docker system prune -a
🥳 Congratulations, the exchange has been successfully installed!
You can open it by your domain name.
**After installation, you need to download the file /app/openex/backend/save_to_self_and_delete.txt and delete it from the server.**
