Last updated at Posted at 2020-01-10

CircleCIの設定でLaravelのマイグレーションが上手くいかずにハマりました、、、

環境

エラー

マイグレーションStep時にエラーになります

#!/bin/bash -eo pipefail
php artisan migrate

In Connection.php line 669:

Exited with code exit status 1

原因

MySQL8.0.4 デフォルトの認証方式変更

MySQL8.0.4以降のログイン認証方式はcaching_sha2_passwordがデフォルトであり、
接続ライブラリがcaching_sha2_passwordに未対応のため接続不可

参考: MySQL8.0 認証方式を変更する(Laravel5)

解決策

.circleci/config.ymlcommand: [--default-authentication-plugin=mysql_native_password]追記

.circleci/config.yml
docker:
  - image: circleci/mysql:8.0
    command: [--default-authentication-plugin=mysql_native_password]
