我的Wordpress安装因为查询速度慢而需要很长时间才能完成。因此产生了很多php-fpm进程并最终占用了所有CPU。
查询
SELECT post_id, meta_key, meta_value
FROM wp_postmeta
WHERE post_id IN (95,150,155,160,165,181,183,186, ...goes on to total post count)
ORDER BY meta_id ASC;
如果你发现它试图为所有发布的帖子发布元数据。这是一个巨大的问题。我无法知道它在哪里运行。
这导致php-fpm进程等待它并产生大量消耗100％CPU的孩子
