Symfony 错误：[PDOException] SQLSTATE[HY000] [2002] 没有这样的文件或目录

Question

I just received some open project files form a customer, where I have to make some adjustments. The project is based ons Symfony Framework and in order to get the project running on my machine, I have to set up the symfony workflow.

I already installed all necessary dev dependencies I guess and when I start my app via:

php bin/console server:run

I get following errors: [PDOException] SQLSTATE[HY000] [2002] No such file or directory

I read couple of threads about this error and most people recommend changing the host from "127.0.0.1" to "localhost" and vice versa.

If i enter "localhost" to be my host, I end up with the error from above.

If I put "127.0.0.1" as my host, I get "connection refused" instead of "No such file or directory"

Answer 1

1. Make sure your local mysql service is running as well.
2. Check database configuration in yaml. Make sure the connection to your local mysql is correct.

3. Run

   app/console doctrine:schema:update --force

to create the database and all the tables for the project.

Let us know if anything of this works or does not.

Answer 2

I had the same problem and fixed it by adding

parameters:
    #...
    database_driver: pdo_mysql

in the app/parameters.yml file.

You should also check if your database_(name|user|password) values are correct.
