项目为了提升性能
需要select查询的时候,读取从库mysql数据
插入修改的时候,操作主库mysql数据
在laravel中只需要配置一下就可以实现
read就是从库的连接信息,write就是主库的连接信息,在.env里可以进行配置
'mysql' => [ 'driver' => 'mysql', 'url' => env('DATABASE_OA_URL'), //配置数据库读写分离 'read' => [ 'host' => env('DB_OA_READ_HOST', '127.0.0.1'), 'port' => env('DB_OA_READ_PORT', '3306'), 'database' => env('DB_OA_READ_DATABASE', 'forge'), 'username' => env('DB_OA_READ_USERNAME', 'forge'), 'password' => env('DB_OA_READ_PASSWORD', ''), ], 'write' => [ 'host' => env('DB_OA_HOST', '127.0.0.1'), 'port' => env('DB_OA_PORT', '3306'), 'database' => env('DB_OA_DATABASE', 'forge'), 'username' => env('DB_OA_USERNAME', 'forge'), 'password' => env('DB_OA_PASSWORD', ''), ], 'unix_socket' => env('DB_OA_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'), ]) : [], ],
