php-fpm：非常高的服务器负载

由于今天我的networking服务器（VPS上的nginx + php-fpm + mysql）非常慢。

htop说：

CPU：（cat / proc / cpuinfo | grep模式）

 model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz 

我认为一个10和100％的CPU使用率的负载是不正常的…我怎样才能解决这个问题？

• 我怎样才能定期logging最密集的CPU进程？
• 为什么挂起的进程在ps中显示CPU占用率过高？
• 为什么DU会导致高CPU使用率？
• virsh vcpu_period和vcpu_quota
• Robocopy备份后，explorer.exe正在使用关键文件服务器上100％的CPU

编辑：我认为这可能是因为MySQL。 这是PhpMyAdmin进程列表：

 Show Full Queries ID User Host Database Command Time Status SQL query Kill 3567 bs localhost bs Sleep 2 --- --- Kill 3575 bs localhost bs Sleep 1 --- --- Kill 3576 bs localhost bs Sleep 1 --- --- Kill 3578 bs localhost bs Sleep 0 --- --- Kill 3579 bs localhost bs Sleep 0 --- --- Kill 3580 bs localhost bs Query 0 Writing to net SELECT count( id ) FROM messages WHERE uid_to =345 AND unread =1 Kill 3581 bs localhost bs Sleep 0 --- --- Kill 3582 unauthenticated user connecting host None Connect login --- Kill 3583 phpmyadmin localhost None Sleep 0 --- --- Kill 3584 root localhost mysql Query 0 --- SHOW PROCESSLIST 

如您所见，只有一个线程可以使用，但Google Analytics（分析）说：

 Right now 429 active visitors on site 

我连接到每个PDO的Mysql。 我怎样才能获得更多的线程？
