Linux环境:Ubuntu 18.04 x64

安装方式:sudo apt-get install php7.3 (默认安装的7.3.6版本)

【查看php-fpm状态】

systemctl status php-fpm

技术图片

systemctl status php7.3-fpm

【查找php-fpm服务】

sudo find / -name *fpm.service

技术图片

查看php-fpm服务配置如下:

cat /lib/systemd/system/php7.3-fpm.service

内容如下:

[Unit]
Description=The PHP 7.3 FastCGI Process Manager
Documentation=man:php-fpm7.3(8)
After=network.target

[Service] 
Type=notify
PIDFile=/run/php/php7.3-fpm.pid
ExecStart=/usr/sbin/php-fpm7.3 --nodaemonize --fpm-config /etc/php/7.3/fpm/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

【安装php-fpm】

使用apt-get,安装前先使用apt-cache search php-fpm搜索一下目前可供选择安装的包

sudo apt-cache search php-fpm

技术图片

如图,因为我们的PHP版本是7.3.6,对应的,我们这里应该选择php7.3-fpm

sudo apt-get install php7.3-fpm

【再次查看php-fpm】

sudo find / -name php7.3-fpm

技术图片

【查看php-fpm启动脚步】

cat /etc/init.d/php7.3-fpm

内容如下:

#!/bin/sh
