How to set up OpenClaw cloud deployment with database replication for high availability?

Tencent Cloud Community 2026-04-2668

To set up OpenClaw cloud deployment with database replication for high availability, follow these steps:

1. Deploy OpenClaw on Cloud Infrastructure

  • Use Tencent Cloud's Virtual Machines (CVM) or Container Service (TKE) to host the OpenClaw application.
  • Provision multiple instances of OpenClaw across different availability zones (AZs) to ensure redundancy.
  • Configure a load balancer (e.g., Tencent Cloud CLB) to distribute traffic evenly among the OpenClaw instances.

2. Set Up Database Replication for High Availability

  • Choose a Database Service: Use Tencent Cloud’s managed database services like TencentDB for MySQL or TencentDB for PostgreSQL, which support built-in replication and high availability.
  • Enable Master-Slave Replication:
    • Deploy a primary (master) database instance in one AZ and one or more secondary (slave) replicas in different AZs.
    • Configure asynchronous or semi-synchronous replication based on your latency and consistency requirements.
  • Automate Failover:
    • Use Tencent Cloud’s database HA features to automatically promote a slave to master if the primary instance fails.
    • Alternatively, use a database proxy like Tencent Cloud’s Database Gateway or open-source tools like HAProxy or ProxySQL to manage read/write routing and failover.

3. Configure OpenClaw to Use the Replicated Database

  • Update the OpenClaw application configuration to connect to the database proxy or load balancer endpoint (e.g., TencentDB’s read/write endpoint) instead of a single database instance.
  • Ensure the application handles connection retries and failover gracefully.

4. Monitor and Scale

  • Use Tencent Cloud’s Cloud Monitor to track the health and performance of both OpenClaw instances and the database replicas.
  • Set up auto-scaling for OpenClaw instances based on traffic patterns.
  • Regularly back up the database and test recovery procedures to ensure data integrity.

Example: TencentDB for MySQL Replication Setup

# Step 1: Create a TencentDB for MySQL primary instance
# Use the Tencent Cloud Console or API to create a MySQL instance in AZ1.

# Step 2: Create a read-only replica in AZ2
# In the TencentDB console, select the primary instance and create a read-only replica in a different AZ.

# Step 3: Configure OpenClaw to use the read/write endpoint
# Update the OpenClaw configuration file (e.g., config.yaml or .env) with the TencentDB read/write endpoint:
database:
  host: cdb-xxxxxx.proxy.tencentcdb.com
  port: 3306
  username: your_db_user
  password: your_db_password
  database: openclaw_db

5. Disaster Recovery and Backup

  • Enable automated backups for the database and store them in Tencent Cloud’s COS (Cloud Object Storage).
  • Test disaster recovery scenarios by simulating AZ or region failures.
