如何通过 PHP-FPM 配置 Nginx 与 PHP 协同工作

1.安装 Nginx

Ubuntu / Debian

1
sudo apt install nginx

CentOS / AlmaLinux / Rocky Linux

Extra Packages for Enterprise Linux (EPEL)

1
sudo yum install epel-release
1
sudo yum install nginx

Fedora

1
sudo dnf install nginx

2.安装 PHP-FPM

Ubuntu / Debian

1
sudo apt install php-fpm

CentOS

CentOS 7

3
sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum-config-manager --enable remi-php74
sudo yum install php php-fpm

CentOS 8

sudo vim /etc/nginx/sites-available/example.com
````

编辑内容：

```shell
server {
        listen 80;
        root /var/www/html;
        index index.php index.html index.htm;
        server_name example.com;
 
        location / {
            try_files $uri $uri/ =404;
        }
 
        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        }
}

保存后，创建软连接到 /etc/nginx/sites-enabled:

1
sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/example.com

确保 fastcgi_pass 定义的 PHP socket 文件名是正确的，例子中是 php7.4-fpm.sock,

1
ls -l /var/run/php/

类似如下的内容：

-rw-r--r-- 1 root     root      5 Dec  1 17:43 php7.4-fpm.pid
srw-rw---- 1 www-data www-data  0 Dec  1 17:43 php7.4-fpm.sock
lrwxrwxrwx 1 root     root     30 Dec  1 17:43 php-fpm.sock -> /etc/alternatives/php-fpm.sock

如果不一致，按自己实际修改即可。

重启 Nginx 服务：

1
sudo systemctl restart nginx.service

4. 测试配置

上述设置中，站点文件根目录 /var/www/html, 创建测试文件：

1
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php

测试访问 http://ip/info.php.
