debain9想要安装php7.3，需要先添加软件源：

apt install ca-certificates apt-transport-https -y
wget -q https://packages.sury.org/php/apt.gpg -O- | apt-key add 
echo "deb https://packages.sury.org/php/ stretch main" | tee /etc/apt/sources.list.d/php.lis
apt update
apt install php7.3-fpm -y
apt install php7.3 php7.3-mysql php7.3-gd php7.3-xml php7.3-cgi php7.3-cli php7.3-curl php7.3-zip php7.3-mbstring unzip -y

5.配置Nginx+PHP7+MariaDB
(1)配置Nginx解析php
编辑vi /etc/nginx/sites-enabled/default

location ~ [^/]\.php(/|$)
        {
        fastcgi_pass   unix:/run/php/php7.3-fpm.sock;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include        fastcgi_params;
		set $path_info "";
		set $real_script_name $fastcgi_script_name;
        if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
           set $real_script_name $1;
           set $path_info $2;
         }
         fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
         fastcgi_param SCRIPT_NAME $real_script_name;
         fastcgi_param PATH_INFO $path_info;
        }

(2）MariaDB配置
shell登录mysql：mysql -u root -p默认无密码，直接回

select Host,User,plugin from mysql.user where User='root';
1

这个时候会发现plugin(加密方式)是unix_socket
#重置加密方法

update mysql.user set plugin='mysql_native_password';  
1

#设置新密码

update mysql.user set password=PASSWORD("newpassword") where User='root'; 
1

#允许远程访问

use mysql;
update user set host='%' where user='root' and host='localhost';
flush privileges;

退出数据库后

vi /etc/mysql/mariadb.conf.d/50-server.cnf
1

将bind-address = 127.0.0.1 改为： bind-address = 0.0.0.0

至此，LNMP就搭建完了，这是我们之后再添加各种服务（自建网盘/博客/论坛/等等等等）的基础。
