无法在 CakePHP 中使用 Apc 缓存 shell

Unable to use Apc cache within CakePHP shell

所以我在尝试 运行 shell 脚本时遇到了这个著名的错误(通过浏览器运行没有问题)

Fatal error: Uncaught CacheException: Cache engine "default" is not properly configured.

默认指向 Apc 缓存。

Cache::config('default', array(
    'engine' => 'Apc',
    'prefix' => 'some_default',
    'duration' => '+1 hour'
));

堆栈跟踪:

#0 /.../lib/Cake/Cache/Cache.php(151): Cache::_buildEngine('default')
#1 /.../app/Config/core.php(381): Cache::config('default', Array)
#2 /.../lib/Cake/Core/Configure.php(72): include('/home/...')
#3 /.../lib/Cake/bootstrap.php(432): Configure::bootstrap(true)
#4 /.../lib/Cake/Console/ShellDispatcher.php(145): require('/home/...')

#6 /.../lib/Cake/Console/ShellDispatcher.php(54): ShellDispatcher->_initEnvironment()
#7 /home/ in /.../lib/Cake/Cache/Cache.php on line 186

环境:

Apache/2.4.18 (Ubuntu)
PHP 7.0.13-0ubuntu0.16.04.1 (cli)
CakePHP v2.8.0

php -i | grep apc:

apc.coredump_unmap => Off => Off
apc.enable_cli => On => On
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

Cake tmp 文件夹 - 权限 777www-data 用户拥有(运行 apache 也拥有) tmp 包含 /cachetmp/cache/modelstmp/cache/persistenttmp/logs,其权限与 tmp.

相同

例如,如果我将默认引擎从 Apc 更改为 Redis,则一切正常。

Apc for php7.0 已弃用,因此您需要安装 apcu 而不是 apcu-bc - 为了与 apc.

兼容

也许只是我的情况,但是当我输入 .../cli/php.ini 那些行时

extension=apcu.so
extension=apc.so

apcu.enabled=1
apc.enable_cli=1

Apc 仍然无法工作,我收到警告:

default cache was unable to write 'key' to Apc cache

当我创建两个文件时它开始工作

.../cli/config.d/apcu.ini 其中包含:

extension=apcu.so

.../cli/config.d/z_apc.ini 其中包含:

extension=apc.so
apc.enable_cli=1

(z前缀为顺序,apc要在apcu之后加载)
