+title: Use PostgreSQL Replace H2 Database to Store Metadata(Optional)     
+sidebar_label: Use PostgreSQL Instead of H2
+---
+PostgreSQL is a RDBMS emphasiing extensibility and SQL compliance.. In addition to default built-in H2 database, HertzBeat allow you to use PostgreSQL to store structured relational data such as monitoring information, alarm information and configuration information.
+
+> If you have the PostgreSQL environment, can be directly to database creation step.
+
+### Install PostgreSQL via Docker
+1. Download and install the Docker environment   
+   Docker tools download refer to [Docker official document](https://docs.docker.com/get-docker/)。
+   After the installation you can check if the Docker version normally output at the terminal.
+   ```
+   $ docker -v
+   Docker version 20.10.12, build e91ed57
+   ```
+2. Install PostgreSQL with Docker
+   ```
+   $ docker run -d --name postgresql -p 5432:5432 -e POSTGRES_USER=root -e POSTGRES_PASSWORD=123456 -e TZ=Asia/Shanghai postgresql:15       
+   ```
+   use```$ docker ps```to check if the database started successfully
+3. Create database in container manually or with [script](https://github.com/dromara/hertzbeat/tree/master/script/docker-compose/hertzbeat-postgresql-iotdb/conf/sql/schema.sql).
+
+### Database creation
+1. Enter postgreSQL or use the client to connect postgreSQL service   
+   ```
+   su - postgres
+   psql
+   ```
+2. Create database named hertzbeat    
+   `CREATE DATABASE hertzbeat;`
+3. Check if hertzbeat database has been successfully created  
+   `\l`
+
+### Modify hertzbeat's configuration file application.yml and switch data source
+
+1. Configure HertzBeat's configuration file
+   Modify `hertzbeat/config/application.yml` configuration file
+   Note⚠️The docker container way need to mount application.yml file locally,while you can use installation package way to unzip and modify `hertzbeat/config/application.yml`  
+   Replace `spring.database` data source parameters, URL account and password.
+```yaml
+spring:
+  datasource:
+    driver-class-name: org.h2.Driver
+    username: sa
+    password: 123456
+    url: jdbc:h2:./data/hertzbeat;MODE=MYSQL
+```
+Specific replacement parameters is as follows and you need to configure account, ip, port according to the postgresql environment:
+```yaml
+spring:
+   config:
+      activate:
+         on-profile: prod
+   datasource:
+      driver-class-name: org.postgresql.Driver
+      username: root
+      password: 123456
+      url: jdbc:postgresql://127.0.0.1:5432/hertzbeat
+      hikari:
+         max-lifetime: 120000
+
+   jpa:
+      database: postgresql
+      hibernate:
+         ddl-auto: update
+      properties:
+         hibernate:
+            dialect: org.hibernate.dialect.PostgreSQLDialect
+```
+
+**Start HertzBeat  visit http://ip:1157/ on the browser  You can use HertzBeat monitoring alarm, default account and password are admin/hertzbeat**

+
+##### docker compose deploys hertzbeat and its dependent services
+
+1. Download the hertzbeat-docker-compose installation deployment script file
+   The script file is located in `script/docker-compose/hertzbeat-postgresql-iotdb` link [script/docker-compose](https://gitee.com/dromara/hertzbeat/tree/master/script/docker-compose/hertzbeat-postgresql-iotdb)
+
+
+2. Enter the deployment script docker-compose directory, execute
+
+   `docker compose up -d`
+
