systemctl isenabled php-fpm

systemctl isenabled php-fpm命令用于检查php-fpm服务是否在系统启动时自动启用。如果该服务已经配置为在系统启动时自动启用，则该命令会返回"enabled"；如果未配置为自动启用，则返回"disabled"。

systemctl enable php-fpm

As an AI language model, I am not capable of executing commands on a machine. However, I can provide you with an explanation of what the "systemctl enable php-fpm" command does.

The "systemctl enable" command is used to enable a service or a daemon to start automatically at boot time. In this case, "php-fpm" is the FastCGI Process Manager for PHP, which is a process manager that manages PHP processes for web servers like Apache and Nginx.

By running "systemctl enable php-fpm", you are instructing the system to start the php-fpm service automatically at boot time. This ensures that the PHP processes are properly managed and available to handle incoming web requests.

[root@fanzhou etc]# systemctl start php-fpm.service Failed to start php-fpm.service: Unit not found.

当你尝试通过 `systemctl` 启动名为 `php-fpm.service` 的系统服务时，收到了 "Unit not found" 错误，这意味着你在系统中找不到对应的 `php-fpm.service` 单元。这可能是以下几个原因造成的：

1. **服务未安装**：确保已经安装了 PHP 7 的官方包，并且包含 `php-fpm` 服务。你可以检查一下是否已安装：

   sudo yum list | grep php7

或者如果是使用 apt-get：

   sudo apt-cache policy php7.4-fpm

2. **服务配置问题**：确认服务是否已在 systemd 中注册。查看系统的服务列表：

   sudo systemctl list-units --type=service | grep php

3. **服务名拼写错误**：确保你输入的 service 名称与实际系统的名称一致。比如，可能是 `php7.4-fpm.service`，而非 `php-fpm.service`。

4. **服务已经被停用**：先检查服务状态：

   sudo systemctl status php-fpm.service

解决这些问题后，再次尝试启动服务：

sudo systemctl start php7.4-fpm.service
