PHP opcache重置+符号链接式部署
PHP opcache重置+符号链接式部署
提问于 2014-05-19 20:21:29
我正在尝试在符号链接风格的部署之后重置PHP opcache。在我的项目中有一个opcache_reset.php文件，它是在文档根目录的符号链接替换后由wget执行的：
<?php
clearstatcache(true);
opcache_reset();尽管如此，旧文件仍然被使用。根据opcache_get_status()的输出，manual_restarts的数量增加了，last_restart_time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opcache_reset.php来纠正错误。
PHP版本为5.5.6，ZendOpcache为7.0.3-dev。Opcache配置：
opcache.blacklist_filename => no value
opcache.consistency_checks => 0
opcache.dups_fix => Off
opcache.enable => On
opcache.enable_cli => On
opcache.enable_file_override => Off
opcache.error_log => no value
opcache.fast_shutdown => 1
opcache.force_restart_timeout => 180
opcache.inherited_hack => On
opcache.interned_strings_buffer => 8
opcache.load_comments => 1
opcache.log_verbosity_level => 1
opcache.max_accelerated_files => 4000
opcache.max_file_size => 0
opcache.max_wasted_percentage => 5
opcache.memory_consumption => 128
opcache.optimization_level => 0xFFFFFFFF
opcache.preferred_memory_model => no value
opcache.protect_memory => 0
opcache.restrict_api => no value
opcache.revalidate_freq => 60
opcache.revalidate_path => Off
opcache.save_comments => 1
opcache.use_cwd => On
opcache.validate_timestamps => On回答 3

原因和ZendOptimizerPlus issue中描述的两种可能的解决方案。我们通过在nginx配置中使用$realpath_root解决了这个问题：
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;Stack Overflow用户

如果你因为某些原因不能在$realpath_root中使用fastcgi_param和使用符号链接风格的部署，那么试着在你的php配置中设置opcache.revalidate_path = On。我找不到任何很好的文档来解释这个ini目录是如何在幕后工作的，但是在我更改了符号链接之后它确实工作了。希望这对任何人都有帮助。

我也面临着这个问题，然后最终我提出了一个解决方案。
$ 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是一个文件或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示例：
