未启用APCu？不能创建固定装置

问题描述

我在使用命令时遇到问题：

PHP bin / console d：f：l

 [Symfony \ Component \ Cache \ Exception \ CacheException]
  APCu is not activated

Symfony 3很好地识别acpu扩展。 有关信息，我在docker上并且已经成功安装了Acpu扩展。

Symfony可以很好地检测缓存，但是我不知道为什么脚本不想启动。我试图从其他DockerFile中汲取灵感，但仍然是同样的问题。

我的PHP DockerFile：

解决方法

您必须为cli启用apc。 如果启动[{id: 1,messenger_id: 3},{id: 2,messenged_id: 5}] // messenger_id != messenged_id != u_id ，则应该具有以下内容：

php -i

您会看到apc.coredump_unmap => Off => Off apc.enable_cli => Off => Off apc.enabled => On => On apc.entries_hint => 4096 => 4096 apc.gc_ttl => 3600 => 3600 apc.mmap_file_mask => no value => no value apc.preload_path => no value => no value apc.serializer => php => php apc.shm_segments => 1 => 1 apc.shm_size => 32M => 32M apc.slam_defense => On => On apc.smart => 0 => 0 apc.ttl => 0 => 0 apc.use_request_time => On => On apc.writable => /tmp => /tmp 设置为apc.enable_cli。

因此，将此行添加到您的Dockerfile中：

Off
