配置

illuminate/database 数据库及版本支持情况如下:

  • MySQL 5.6+
  • PostgreSQL 9.4+
  • SQLite 3.8.8+
  • SQL Server 2017+

    数据库配置文件位置为 config/database.php

    return [
     // 默认数据库
     'default' => 'mysql',
     // 各种数据库配置
     'connections' => [
    
         'mysql' => [
             'driver'      => 'mysql',
             'host'        => '127.0.0.1',
             'port'        => 3306,
             'database'    => 'webman',
             'username'    => 'webman',
             'password'    => '',
             'unix_socket' => '',
             'charset'     => 'utf8',
             'collation'   => 'utf8_unicode_ci',
             'prefix'      => '',
             'strict'      => true,
             'engine'      => null,
         ],
    
         'sqlite' => [
             'driver'   => 'sqlite',
             'database' => '',
             'prefix'   => '',
         ],
    
         'pgsql' => [
             'driver'   => 'pgsql',
             'host'     => '127.0.0.1',
             'port'     => 5432,
             'database' => 'webman',
             'username' => 'webman',
             'password' => '',
             'charset'  => 'utf8',
             'prefix'   => '',
             'schema'   => 'public',
             'sslmode'  => 'prefer',
         ],
    
         'sqlsrv' => [
             'driver'   => 'sqlsrv',
             'host'     => 'localhost',
             'port'     => 1433,
             'database' => 'webman',
             'username' => 'webman',
             'password' => '',
             'charset'  => 'utf8',
             'prefix'   => '',
         ],
     ],
    ];

    使用多个数据库

    通过Db::connection('配置名')来选择使用哪个数据库,其中配置名为配置文件config/database.php中的对应配置的key

    例如如下数据库配置:

 return [
     // 默认数据库
     'default' => 'mysql',
     // 各种数据库配置
     'connections' => [

         'mysql' => [
             'driver'      => 'mysql',
             'host'        =>   '127.0.0.1',
             'port'        => 3306,
             'database'    => 'webman',
             'username'    => 'webman',
             'password'    => '',
             'unix_socket' =>  '',
             'charset'     => 'utf8',
             'collation'   => 'utf8_unicode_ci',
             'prefix'      => '',
             'strict'      => true,
             'engine'      => null,
         ],

         'mysql2' => [
              'driver'      => 'mysql',
              'host'        => '127.0.0.1',
              'port'        => 3306,
              'database'    => 'webman2',
              'username'    => 'webman2',
              'password'    => '',
              'unix_socket' => '',
              'charset'     => 'utf8',
              'collation'   => 'utf8_unicode_ci',
              'prefix'      => '',
              'strict'      => true,
              'engine'      => null,
         ],
         'pgsql' => [
              'driver'   => 'pgsql',
              'host'     => '127.0.0.1',
              'port'     =>  5432,
              'database' => 'webman',
              'username' =>  'webman',
              'password' => '',
              'charset'  => 'utf8',
              'prefix'   => '',
              'schema'   => 'public',
              'sslmode'  => 'prefer',
          ],
 ];

像这样切换数据库。

// 使用默认数据库,等价于Db::connection('mysql')->select(...);
$users = Db::select(...); 
// 使用mysql2
$users = Db::connection('mysql2')->select(...);
// 使用pgsql
$users = Db::connection('pgsql')->select(...);
