php fpm 网站上的文档说，从 5.3.3 开始，php fpm 是 coe php 的一部分
我运行的是 5.3.10，如何检查它是否正常工作？我以为这是一个在端口上运行的服务？
假设您使用的是 Linux，通过搜索进程列表来检查 php-fpm 是否正在运行：
ps aux | grep php-fpm
如果通过 IP 运行（而不是通过 Unix 套接字），那么您还可以检查端口：
netstat -an | grep :9000
或使用 nmap：
nmap localhost -p 9000
最后，我读到您可以请求状态，但根据我的经验，这被证明是不可靠的：
/etc/init.d/php5-fpm status
对于 php7.0-fpm 我调用：
service php7.0-fpm status
php7.0-fpm启动/运行，进程25993
现在看好的部分。进程名称实际上是php-fpm7.0
echo `/bin/pidof php-fpm7.0`
26334 26297 26286 26285 26282
以下是如何使用 php-fpm 7 上的套接字来完成此操作
install socat
apt-get install socat
#!/bin/sh
if echo /dev/null | socat UNIX:/var/run/php/php7.0-fpm.sock - ; then
echo "$home/run/php-fpm.sock connect OK"
else
echo "$home/run/php-fpm.sock connect ERROR"
fi
您还可以这样检查服务是否正在运行。
service php7.0-fpm status | grep running
它会回来的
Active：自周日 2017-04-09 12:48:09 PDT 起处于活动状态（运行）； 48 秒前
如果它对在 amilinux 上安装了 php5.6 和 php-fpm 的人有帮助，它是：
sudo /etc/init.d/php-fpm-5.6 statusPHP-FPM 是一种在需要时生成新 PHP 进程的服务，通常通过 nginx 等 fast-cgi 模块。您可以通过检查 init.d 脚本来判断（有一定的误差），例如“sudo /etc/init.d/php-fpm 状态”
使用什么端口或unix文件套接字取决于配置，但通常只是TCP端口9000。即127.0.0.1:9000
判断其是否正确运行的最佳方法是运行 nginx，并设置一个将 fast-cgi 传递给 PHP-FPM 的虚拟主机，然后使用 wget 或浏览器检查它。
自动重启php-fpm的bash脚本：
#!/bin/bash
is_running=`service php7.4-fpm status | grep running`
if [[ ! $is_running ]]
then
echo 'php7.4-fpm is running'
else
echo 'php7.4-fpm is not running';
fi
每 5 分钟检查一次的 Cron 配置（
/root/check_php7.4_status.sh*/5 * * * * /root/check_php7.4_status.sh 2>&1 >> '/root/check_php7.4_status.log'
我在运行 cPanel 和 WHM 的 Centos 7 服务器上苦苦挣扎了一段时间，PHP-FPM 有时变得无响应。 PHP-FPM服务显示正在运行，但不响应请求。
我的数据中心的团队也在尝试帮助我找到永久解决方案，但到目前为止我们还没有任何运气。
在此期间，我开发了一个 Node.js 监控系统，该系统通过打开在 PHP FPM 上运行的测试文件来运行。系统使用 HTTP:// 和 HTTPS:// 调用，同时引用服务器的 IP 地址和站点主机名，以防止因网络、DNS 或其他相关错误而导致的任何不必要的重新启动。如果系统没有收到有效响应，它会重新启动 PHP FPM 并向我发送一封电子邮件。
代码和方法如下，如果有人觉得有用的话。
在您的服务器上创建一个文件夹，例如/home/itdint/monitor/ 并在该文件夹中创建一个名为 monitor.js 和 init.php 的文件。在可以在服务器上测试的域上创建 testFPM.php 文件。
---节点进程（monitor.js），您需要安装的唯一模块是 axios（例如 npm install axios）
const axios = require('axios');
const { execSync } = require('child_process');
const failureEmail = "[your email address]";
const serverIP = "[server ip]"; //e.g. 8.8.8.8
const testDomain = "[your domain name]"; //e.g. example.com
const testFile = "testFPM.php";
const restartFPMCommand = "/scripts/restartsrv_apache_php_fpm";
const failedEmailCommand = 'mail -s \"FPM Restarted\" '+failureEmail+' < /dev/null';

这是我编写的一个简单但我认为很漂亮的脚本，它可以从 CRON 运行，并将检查服务器上安装的所有版本的 php-fpm 是否正在运行。这是为 Ubuntu 22.04 编写的，所以 YMMV。 （此信息部分来自此页面上的信息，但奇怪的是没有人采取额外的步骤来使用运行“php-fpm status”时返回的状态
这个想法是对 /etc/init.d 中找到的每个 php-fpm 版本进行状态检查，然后检查返回代码。如果返回代码不为空，则表示出现问题，我们会发出通知并尝试重新启动。

then
