How to start to debug with backend application about abp-next-admin

[NiceLisan]

yeah, it's real frustrated now.
can you share the whole sln project structure that can be compiled without any error.
currently each project is missing the correct appsettings.Development.json; although you supplied them in the seperated folder.
sincerely thanks

some backend services error looks like this. but i can promise i have set the correct parameters of rabbitmq in the appsetting file.

After clone the project, you will need to restore apigateway-init.sql to your gateway administration database. Then copy the configuration files to the root directory of the service and double-click the start-all-service.bat file to move all the background services. Currently, you need to change the connection string and RabbitMQ connection information according to your server configuration

maybe you are wrong. you've missed the database migration job. it's really miserable!!!
all the service database migration are totally miserable, you didnot write any help tip documets about that.

maybe lots of someone like me could not run the source projects successfully. so frustrated!

RabbitMQ.Client.Exceptions.OperationInterruptedException: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=530, text='NOT_ALLOWED - vhost multi.service.test not found'

This error has prompted you. In my RabbitMQ configuration, the VisualHost name is multi-service.test, and you need to change the configuration of your own RabbitMQ server

Launching the error stack will send out, and I'll show you where the configuration went wrong, like the one on the second floor

in my own practice, the cap rabbit mq WILL create the exchange,queue automaticallly.
in your meaning, i should create the exchange,channel,queue in the rabbitmq server by myself manually way?
it's hard to imagine that.

and will you provide the sln structure file to help new beginners compile your source projects effectively？

[colinin]

@NiceLisan
I'm ready to create a series of Dockerfile and build the entire service application with docker-componse, so stay with me

[NiceLisan]

@colinin
thanks, but i'm concerning on how to build the source project files and run successfully. it's really appreciated that you can provide one sln file that could be compiled by the vs2019.

[colinin]

@NiceLisan
Even if RabbitMQ is using the default VitualHost, it is essential that you change to the default VitualHost, such as /, and that the connection user and password are specified

[colinin]

If you do not want to restore the database structure of the gateway, then you can deactivate the management gateway service. I can export an ocelot.Json file, but this is not recommended, because you will need to implement the dynamic management of the gateway yourself

[gerryge]

@colinin
Can you write the detail steps for different scenarios, for example:

1. Locally debug
2. Docker
   For local debug, can you write how to change database connection, migration database and so on...
   I totally can not understand you say "you will need to restore apigateway-init.sql to your gateway administration database", do you mean I create a database first then execute your apigateway-init.sql?

[gerryge]

I think the purpose of your open source is to have more people participate in your project, learn from each other, and improve each other. Now the biggest problem, we can't successfully start your project.

2. 我完全无法理解您说“您将需要将apigateway-init.sql还原到网关管理数据库”，您的意思是我先创建一个数据库，然后执行您的apigateway-init.sql吗？

If you have read the documentation, there should be no doubt
https://docs.abp.io/en/abp/latest/Entity-Framework-Core-Migrations

actually , we had to create the apigateway database manually, then import the apigateway-init.sql , i tried add the apigateway migration failed. because you didnot share the appsettings.json file in the entityframeworkcore\host project, it's confusing which file can be used to migrate.
sincerely hope you can share the all-projects-in-one sln file that can help us to understand your open source projects.

Now that, I've written the gateway initialization script into the seed data, starting the Gateway management project automatically initializes the gateway data, but you need to combine the EntityFramework documentation to ensure that the project database is successfully migrated

now, i've tried with your latest commitment again.
i build the projects successfully;
i configured the database, rabbitmq successfully.
i seed the database successfully.

but i still encountered the following errors;

1: in the service authserver.host

MySql.Data.MySqlClient.MySqlException (0x80004005): Table 'platform.abpsettings' doesn't exist
 

2: in the service \LINGYUN.ApiGateway.HttpApi.Host
MySql.Data.MySqlClient.MySqlException (0x80004005): Table 'platform.abppermissiongrants' doesn't exist

3: in the service admin\LINGYUN.BackendAdminApp.Host

MySql.Data.MySqlClient.MySqlException (0x80004005): Table 'platform.abppermissiongrants' doesn't exist

4: in the service messages\LINGYUN.Abp.MessageService.HttpApi.Host

everything works well
 i can run without any errors.

5: in the service platform\LINGYUN.Platform.HttpApi.Host;
it's the only lucky one , i can run without any errors.

can you help me to figure out what the hell mistakes had blocked me. sincerely thanks.

[NiceLisan]

while i tried to add the two table Table 'platform.abpsettings','platform.abppermissiongrants' manually , now the service 1,3,4,5
can run successfully. but the service LINGYUN.ApiGateway.Host and 'LINGYUN.ApiGateway.HttpApi.Host' still has the following fatal errors:
