+# Local Debugging Setup (Advance)
+
+* IntelliJ IDEAS
+
+* To bypass Spring Security to troubleshoot resource module independently, use this annotation
+
+  * remove `@EnableResourceServer`
+  * add exclusion `exclude={SecurityAutoConfiguration.class}`
+
+  ```java
+  @SpringBootApplication(exclude={SecurityAutoConfiguration.class})
+  @RestController
+  //@EnableResourceServer
+  //@EnableScheduling
+  public class ResourceApplication {
+  ...
+  }
+  ```
+
+* Setup debugger environment 
+
+  * for remote db. 
+    * Note : For `authserver`, not able to launch if remote db is Read-Only replica as the code will execute `schema.sql` against `uaa` table, which required write access
+
+  ```text
+  DATABASE_SERVER_HOST=127.0.0.1;DATABASE=razerpay-malaysia-product;DATABASE_SERVER_USERNAME=tenghieyik;DATABASE_SERVER_PASSWORD=Razer*3ngF0RlIF32
+  ```
+
+  * for local db (according to your local db setup)
+
+  ```text
+  DATABASE_SERVER_HOST=127.0.0.1;DATABASE=razerpay-malaysia-product;DATABASE_SERVER_USERNAME=razerpay;DATABASE_SERVER_PASSWORD=razerpay-singapore
+  ```
+
+* Happy debugging !!!!
+

+
+## Remote DB connection via tunnel (Malaysia)
+
+* SSH tunnel setup at local computer
+
+  * Connect to Malaysia VPN
+
+  * Setup SSH Tunnel to an authorised EC2 for connecting to Malaysia sql sb.
+
+    ```shell
+    $ ssh -L 3306:rr-zf81fzm6ija52q623.mysql.kualalumpur.rds.aliyuncs.com:3306 tenghieyik@172.22.4.252
+    ```
+
+  * Test tunnel setup connection using `MySQL Workbench` to connect `localhost:3306`
+  * Setup IntelliJ setting to connect DB via `localhost:3306`
+
+### For docker container setup
+
+* Connect remote db from docker container via docker host SSH tunnel
+
+  * SSH tunnel
+
+    ```shell
+    $ ssh -L host.docker.internal:3306:rr-zf81fzm6ija52q623.mysql.kualalumpur.rds.aliyuncs.com:3306 tenghieyik@172.22.4.252
+    
+    // grab the host.docker.internal IP Address
+    $ ping host.docker.internal
