Question

我试图在符号链接式部署后重置PHP opcache。我的项目中有opcache_reset.php文件，在文档根的符号链接替换之后由wget执行：

<?php
clearstatcache(true);
opcache_reset();

尽管如此，仍然使用旧文件。根据{{1}}输出，opcache_get_status()增加的数量manual_restarts保持最新，但文件路径仍然过时。我需要在部署后一分钟左右手动调用last_restart_time以使事情正确。

PHP版本是5.5.6，ZendOpcache是7.0.3-dev。 Opcache配置：

opcache_reset.php

Answer 1

ZendOptimizerPlus issue中描述的原因和两种可能的解决方案。我们在nginx配置中使用$realpath_root来解决它：

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;

Answer 2

如果由于某种原因，您无法在$realpath_root中使用fastcgi_param并无法使用符号链接样式部署，请尝试在您的php ini配置中设置opcache.revalidate_path = On。我找不到任何好的文档来解释这个ini目录的工作原理，但是在更改符号链接后它确实起作用了。希望这对任何人都有帮助。

Answer 3

我也遇到了这个问题，最后我做出了解决方案。

$ curl -sO http://gordalina.github.io/cachetool/downloads/cachetool.phar
$ chmod +x cachetool.phar

您可以连接到自动猜测的fastcgi服务器（如果/var/run/php5-fpm.sock是文件或127.0.0.1:9000）

apc
  apc:bin:dump             Get a binary dump of files and user variables
  apc:bin:load             Load a binary dump into the APC file and user variables
  apc:cache:clear          Clears APC cache (user, system or all)
  apc:cache:info           Shows APC user & system cache information
  apc:cache:info:file      Shows APC file cache information
  apc:key:delete           Deletes an APC key
  apc:key:exists           Checks if an APC key exists
  apc:key:fetch            Shows the content of an APC key
  apc:key:store            Store an APC key with given value
  apc:sma:info             Show APC shared memory allocation information
opcache
  opcache:configuration    Get configuration information about the cache
  opcache:reset            Resets the contents of the opcode cache
  opcache:status           Show summary information about the opcode cache
  opcache:status:scripts   Show scripts in the opcode cache

您可以注意到内存，缓存键，每次点击都变为0 :-)。它非常有用。我也很容易将它与Ansible一起感兴趣。
