Debian10上安装PHP(支技术pdo扩展)

安装PHP

• 安装更新与PHP证书安装

apt update && apt upgrade
apt install ca-certificates apt-transport-https 
wget -q https://packages.sury.org/PHP/apt.gpg -O- | sudo apt-key add -
echo "deb https://packages.sury.org/PHP/ buster main" | tee /etc/apt/sources.list.d/PHP.list

• 安装PHP

apt update
apt install PHP7.3
apt install PHP7.3-cli PHP7.3-common PHP7.3-curl PHP7.3-gd PHP7.3-json PHP7.3-mbstring PHP7.3-MysqL PHP7.3-xml 

• 配置pdo(去掉注释)

nano /etc/PHP/7.3/apache2/PHP.ini
extension=pdo_MysqL

安装MariaDB

1. 安装MariaDB
   apt install mariadb-server -y
2. 设置开机启动MariaDB
   systemctl enable mariadb.service
systemctl restart mariadb.service
3. 设置MariaDB权限与密码等

• 登陆MariaDB:无密码MysqL -uroot有密码用MysqL -uroot -p123456
• 显示数据库show databases;
• 选择数据库use MysqL;
• 查询用户SELECT host,user,password from user;
• 设置密码set password for 'root'@'localhost' =password('123456');
• 远程连接设置grant all privileges on *.* to root@'%'identified by '123456';
• 如果是不是root则先新建用户
  create user '用户名'@'%' ip地址 by '密码'
  测试pdo代码(方便不懂的人使用修改,注意127.0.0.1与localhost有可能不一样!请修改MysqL密码)

重启apache服务

systemctl restart apache2.service
```
以上完成相关设置
