安装PHP-fpm

先确定php版本php -v

bash

PHP 8.1.2-1ubuntu2.11 (cli) (built: Feb 22 2023 22:56:18) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2-1ubuntu2.11, Copyright (c), by Zend Technologies

可以看到我这里php版本是8.1（目前默认安装的最新版） 2. 安装对应版本的PHP-fpmsudo apt-get install php-fpm 3. 查看php-fpm的状态sudo systemctl status php8.1-fpm

bash

配置Nginx和PHP-FPM

使用Nginx发布PHP网页，就需要这两个程序之间有沟通，这个时候就需要对其进行相应配置

配置Nginxsudo vim /etc/nginx/sites-available/default
在其中自带的server字段中找到# pass PHP scripts to FastCGI server下的关于php的被注释的子字段（大约第56行），将其改为（或者直接添加）： 注意PHP版本号！

vim

location ~ \.php$ {
               include snippets/fastcgi-php.conf;
               fastcgi_pass unix:/run/php/php8.1-fpm.sock;
        }

如果你找不到位置，我这里提供其他部分的内容：

vim

server_name _;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }
在这里👉location ~ \.php$ {
               include snippets/fastcgi-php.conf;
               fastcgi_pass unix:/run/php/php8.1-fpm.sock;
        }👈在这里
        # pass PHP scripts to FastCGI server
        #
        #location ~ \.php$ {
        #       include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
        #       fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        #}

配置php-fpmvim /etc/php/8.1/fpm/pool.d/www.conf

vim

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /run/php/php8.1-fpm.sock

一般来说自带的配置文件不用改，我没有做任何更改 4. 重启一下nginx和php-fpm：sudo systemctl restart nginx&sudo systemctl restart php8.1-fpm

测试PHP站点

进入默认站点目录cd /var/www/html
新建php文件sudo vim test.php
写入测试内容<?php phpinfo();?>
保存退出
访问http://$IP/test.php，可以显示PHP系统信息即表示PHP站点搭建完成！
