Step-by-Step Deployment of Open-Falcon Monitoring System with Redis, MySQL, and Go

This article provides a complete deployment tutorial for the Open-Falcon monitoring platform, covering prerequisite installations, backend setup, frontend preparation, and final access.

1. Install Redis

yum install redis -y

redis-server &

2. Prepare MySQL (MariaDB)

yum install mariadb mariadb-server -y

systemctl start mariadb

systemctl enable mariadb

Test login: mysql -uroot -p Initialize schema by cloning the Open-Falcon repository and importing SQL files:

cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git

cd /tmp/falcon-plus/scripts/mysql/db_schema/

mysql -h 192.168.236.181 -u root -p < 1_uic-db-schema.sql

mysql -h 192.168.236.181 -u root -p < 2_portal-db-schema.sql

mysql -h 192.168.236.181 -u root -p < 3_dashboard-db-schema.sql

mysql -h 192.168.236.181 -u root -p < 4_graph-db-schema.sql

mysql -h 192.168.236.181 -u root -p < 5_alarms-db-schema.sql

Set MySQL root password: mysqladmin -uroot password "12345" 3. Install Go language yum install golang -y 4. Backend setup (Open-Falcon)

Download and extract the binary package:

wget https://github.com/open-falcon/falcon-plus/releases/download/v0.3/open-falcon-v0.3.tar.gz

tar xf open-falcon-v0.3.tar.gz -C /home/work/open-falcon

Edit configuration files (replace MySQL username and password as needed):

vim /home/work/open-falcon/aggregator/config/cfg.json

vim /home/work/open-falcon/graph/config/cfg.json

vim /home/work/open-falcon/hbs/config/cfg.json

vim /home/work/open-falcon/nodata/config/cfg.json

vim /home/work/open-falcon/api/config/cfg.json

vim /home/work/open-falcon/alarm/config/cfg.json

Start the backend modules: ./open-falcon start Typical output shows the graph service PID, e.g., [falcon-graph] 10848.

5. Frontend setup (Open-Falcon Dashboard)

Clone the dashboard repository: git clone https://github.com/open-falcon/dashboard.git Download and install ez_setup.py and pip:

wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py

python ez_setup.py --insecure

wget https://pypi.python.org/packages/.../pip-9.0.1.tar.gz

tar xf pip-9.0.1.tar.gz

cd pip-9.0.1

python setup.py install

Create a virtual environment and activate it:

virtualenv ./env

source env/bin/activate

Install required Python packages:

./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple

Configure the dashboard (edit config.py as needed) and start it: ./control start Typical startup logs show Gunicorn listening on port 8081:

[2021-10-09 09:49:04 +0000] [8143] [INFO] Listening at: http://0.0.0.0:8081 (8143)

6. Access the UI

Open a web browser and navigate to the dashboard URL (e.g., http://<server-ip>:8081) to view Open-Falcon's monitoring interface.
