title: Use PostgreSQL Replace H2 Database to Store Metadata(Recommended)
|
|
sidebar_label: Meta Store PostgreSQL (Recommended)
|
|
---
|
|
|
|
PostgreSQL is an RDBMS emphasizing extensibility and SQL compliance. In addition to default built-in H2 database, Apache HertzBeat™ allows you to use PostgreSQL to store structured relational data such as monitoring information, alarm information and configuration information.
|
|
|
|
> If you have a PostgreSQL environment, you can skip directly to the 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.
|
|
|
|
```shell
|
|
$ docker -v
|
|
Docker version 20.10.12, build e91ed57
|
|
```
|
|
|
|
2. Install PostgreSQL with Docker
|
|
|
|
```shell
|
|
docker run -d --name postgresql -p 5432:5432 -e POSTGRES_USER=root -e POSTGRES_PASSWORD=123456 -e TZ=Asia/Shanghai postgres:15
|
|
```
|
|
|
|
use```$ docker ps```to check if the database started successfully
|
|
|
|
### Database creation
|
|
|
|
1. Enter postgreSQL or use the client to connect postgreSQL service
|
|
|
|
```shell
|
|
su - postgres
|
|
psql
|
|
```
|
|
|
|
2. Create database named hertzbeat
|
|
|
|
```sql
|
|
CREATE DATABASE hertzbeat;
|
|
```
|
|
|
|
3. Check if hertzbeat database has been successfully created
|
|
|
|
```sql
|
|
SELECT * FROM pg_database where datname='hertzbeat';
|
|
```
|
|
|
|
### 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
|
|
hikari:
|
|
max-lifetime: 120000
|
|
|
|
jpa:
|
|
show-sql: false
|
|
database-platform: org.eclipse.persistence.platform.database.MySQLPlatform
|
|
database: h2
|
|
properties:
|
|
eclipselink:
|
|
logging:
|
|
level: SEVERE
|
|
```
|
|
|
|
Specific replacement parameters are as follows and you need to configure account, ip, port according to the postgresql environment:
|
|
|
|
```yaml
|
|
spring:
|
|
datasource:
|
|
driver-class-name: org.postgresql.Driver
|
|
username: root
|
|
password: 123456
|
|
url: jdbc:postgresql://postgresql:5432/hertzbeat
|
|
hikari:
|
|
max-lifetime: 120000
|
|
jpa:
|
|
show-sql: false
|
|
database-platform: org.eclipse.persistence.platform.database.PostgreSQLPlatform
|
|
database: postgresql
|
|
properties:
|
|
eclipselink:
|
|
logging:
|
|
level: SEVERE
|
|
```
|
|
|
|
> Note: The above applies to the method of downloading and installing the package. For local data source switching, simply complete the [Database creation](./postgresql-change#database-creation) and modify the configuration in `hertzbeat-startup/src/main/resources/application.yml`.
