问题

Laravel说明文档中的 Redis 发布与订阅案例,命令行运行php artisan redis:subscribe 到60s自动断开并报错

 [Predis\Connection\ConnectionException]
Error while reading line from the server. [tcp://127.0.0.1:6379]

解决

config/database.php配置文件中,找到redis配置项,添加一行如下

'redis' => [

        'cluster' => false,

        'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
'read_write_timeout' => 0,//new
], ]

原因

据Predis作者在配置文件中说明,因为在底层网络资源上执行读取或写入操作时使用了超时,默认设置了timeout 为60s。
