笔记：

先安装一下这个命令 add-apt-repository
apt-get install software-properties-common

添加第三方源：
add-apt-repository ppa:ondrej/php
apt-get update

安装php:

apt-get install php-fpm
service php7.3-fpm start

nginx配置文件中注意的点,一旦遇到"Primary script unknown"，检查下面三个地方：

root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

server {
    listen       ;
    server_name  127.0.0.1;
    access_log  /var/log/nginx/default.access.log  main;
    error_log /var/log/nginx/default.error.log;
    root   /usr/share/nginx/html;
    location / {
        index  index.html index.htm;
    }
    location ~ \.php$ {
        fastcgi_pass   127.0.0.1:;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

php-fpm配置文件中注意的点：
listen = 127.0.0.1:9000
