<!-- Answer --> You do not need to reinstall DevLake. You can resolve the error code 500 when connecting a MySQL RDS instance by following these steps: 1. Comment out the MySQL part in your `docker-compose.yml` file: ```yaml # mysql: # image: mysql:8 # volumes: # - mysql-storage:/var/lib/mysql # restart: always # ports: # - "127.0.0.1:3306:3306" # environment: # MYSQL_ROOT_PASSWORD: admin # MYSQL_DATABASE: lake # MYSQL_USER: merico # MYSQL_PASSWORD: merico # command: # --character-set-server=utf8mb4 # --collation-server=utf8mb4_bin ``` 2. Comment out the MySQL volume: ```yaml # volumes: # mysql-storage: ``` 3. Comment out the `depends_on mysql` part: ```yaml # depends_on: # - mysql ``` 4. Set `DB_URL` to your own DB_URL in the `.env` file: ```bash DB_URL="mysql://YOUR_USER:YOUR_PASSWORD@YOUR_IP:YOUR_PORT/lake?charset=utf8mb4&parseTime=True" # Don't forget to create db named `lake` in your own db, and set character-set-server=utf8mb4, collation-server=utf8mb4_bin as below # character-set-server=utf8mb4 # collation-server=utf8mb4_bin ``` 5. Run `docker compose up -d`. Additionally, if you encounter the error "The total number of locks exceeds the lock table size," you can solve it by increasing the `innodb_buffer_pool_size` to a higher value in your MySQL configuration. Here is an example of how to modify the `docker-compose` file for MySQL: ```yaml mysql: image: mysql:8 ... # add the following line to the mysql container command: --innodb-buffer-pool-size=200M ``` These steps should help you connect to your MySQL RDS instance without needing to reinstall DevLake <sup>[[1]](https://github.com/apache/incubator-devlake-website/blob/main/versioned_docs/version-v0.16/GettingStarted/DockerComposeSetup.md)</sup><sup>[[2]](https://github.com/apache/incubator-devlake-website/blob/main/versioned_docs/version-v0.19/Troubleshooting/Configuration.md)</sup><sup>[[3]](https://github.com/apache/incubator-devlake-website/blob/main/versioned_docs/version-v0.21/Troubleshooting/Configuration.md)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
