Laravel 8 多数据库连接

Question

我想在我的项目中连接postgresql和mysql。

.env 文件在下面

DB_CONNECTION=pgsql
DB_HOST=175.145.23.01
DB_PORT=5432
DB_DATABASE=test_local
DB_USERNAME=birgul_ayaz
DB_PASSWORD=h4CzT*tiCzr21


DB_CONNECTION_SECOND=test
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=test_deneme
DB_USERNAME=root
DB_PASSWORD=''

config/database.php 在下面

第一个mysql连接：

'mysql' => [
        'driver' => 'mysql',
        'url' => env('DATABASE_URL'),
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'test_deneme'),
        'username' => env('DB_USERNAME', 'root'),
        'password' => env('DB_PASSWORD', ''),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'prefix_indexes' => true,
        'strict' => true,
        'engine' => null,
        'options' => extension_loaded('pdo_mysql') ? array_filter([
            PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
        ]) : [],
    ],

second=postgresql 连接

'pgsql' => [
    'driver' => 'pgsql',
    'url' => env('DATABASE_URL'),
    'host' => env('DB_HOST', '127.0.0.1'),
    'port' => env('DB_PORT', '5432'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'charset' => 'utf8',
    'prefix' => '',
    'prefix_indexes' => true,
    'schema' => 'public',
    'sslmode' => 'prefer',
],

**当我在 Contoller 中使用 connection('test') 时。

$dd= DB::connection('test')->table('test_deneme')->user_name;` 

页面出现此错误 "SQLSTATE[08006] [7] 收到 SSL 协商的无效响应：Y (SQL: select * from "bo_session" where "id" = BVx6RU7dtpnIJjfPHRJrVf1RVMO7SR4c81Fkxp9n limit 1)"

如何解决这个问题？？

Answer 1

在 .env 文件中，您正在定义 HOST、PORT、USERNAME 等的值。在您的 .env 文件中，您将使用 pgsql 值覆盖 mysql 值。

.env

...
DB_HOST=175.145.23.01
DB_PORT=5432
...
DB_HOST_SECOND=127.0.0.1
DB_PORT_SECOND=3306
...

config/database.php

'mysql' => [
        ...
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        ...
],

'pgsql' => [
    ...
    'host' => env('DB_HOST_SECOND', '127.0.0.1'),
    'port' => env('DB_PORT_SECOND', '5432'),
    ...
],
