# How to run this blog example server
1. You should ensure that your mysql server is running.
2. Ensure that the database named `testdb` has been created,
otherwise you should execute the following database script:
```mysql
create database testdb;
```
3. Modify the `configs/config.yaml` file and add your mysql information in the data source:
```yaml
data:
database:
driver: mysql
source: root:password@tcp(127.0.0.1:3306)/testdb?parseTime=True
```
4. Run your blog server:
```bash
$ go generate ./...
$ kratos run
```
