php opcache运行时配置参数详解+laravel opcache配置

谁践踏了优雅 2022-05-27 01:07 422阅读 0赞

这段是从别人那搬来的，下面是自己实践，主要还是记录坑，避免更多的人跳没必要的坑。

一、配置php.ini

PHP的opcode缓存又出了新成员（说新不新，也有一段日子了），那就是opcache。新浪微博等都在使用，惠新宸老师强力推荐。本人最近根据官网地址（http://www.php.net/manual/zh/book.opcache.php）整理了一下，其安装非常简单，5.5.0 后将自动在php内核中，不必单独安装，之前的版本的安装也同其它php扩展一样，源码地址http://pecl.php.net/package/ZendOpcache，就不赘述了。

那么在安装后如何使用并配置opcache，使之能更好地为我们服务呢？整理了一下其在php.ini中各参数的使用说明，供大家参考，有一些不太懂的，就留空了，还请高手赐教。

二、laravel opcache配置

1、用以下命令直接安装

composer require appstract/laravel-opcache

2、用php artisan查看是否有opcache命令

opcache

opcache:clear        Clear the opcode cache

opcache:config       Show your opcode cache configuration

opcache:optimize     Pre-compile your application code

opcache:status       Show state information, memory usage, etc..

3、注意在本地执行的时候会报错

$ php artisan opcache:clear

The requested URL returned error: 500 Internal Server Error

Url: http://localhost/opcache-api/clear?key=eyJpdiI6IkM1XC9HMFwvK2FheFYwWENaS010WHFVdz09IiwidmFsdWUiOiJRQ1AxNVRwa1JiVnJyeDVHejd5UTZnPT0iLCJtYWMiOiI3NDlkNzJlNjIwOWYyYmU1YWJiMDU0YjIzNGE3MjJjNGMwOTg3Nzc3YzM5YTc3NjAwMDBhMjQzYTBkNDQ1MWIzIn0%3D
