## Overview
|
|
|
|
Configure database replication for disaster recovery, load distribution, and high availability. Covers master-slave, multi-master replication, and monitoring strategies.
|
|
|
|
## When to Use
|
|
|
|
- High availability setup
|
|
- Disaster recovery planning
|
|
- Read replica configuration
|
|
- Multi-region replication
|
|
- Replication monitoring and maintenance
|
|
- Failover automation
|
|
- Cross-region backup strategies
|
|
|
|
## Quick Start
|
|
|
|
**PostgreSQL - Configure Primary Server:**
|
|
|
|
```sql
|
|
-- On primary server: postgresql.conf
|
|
-- wal_level = replica
|
|
-- max_wal_senders = 10
|
|
-- wal_keep_size = 1GB
|
|
|
|
-- Create replication user
|
|
CREATE ROLE replication_user WITH REPLICATION ENCRYPTED PASSWORD 'secure_password';
|
|
|
|
-- Allow replication connections: pg_hba.conf
|
|
-- host replication replication_user standby_ip/32 md5
|
|
|
|
-- Enable WAL archiving for continuous backup
|
|
-- archive_mode = on
|
|
-- archive_command = 'test ! -f /archive/%f && cp %p /archive/%f'
|
|
```
