02-mysql光速入门

mysql基础命令:
1.设置密码
mysqladmin password

2.使用账号密码连接
mysql -uroot -p123

3.查看数据库

> show databases;

4.切换到数据库里

> use mysql;

5.查看库里面有哪些表

> show tables;

6.查询当前数据库有哪些用户

> select user,host from mysql.user;
  查询   字段      从   库.表;

MariaDB [(none)]> select user,host from mysql.user;

        include fastcgi_params;
    }
}
EOF
nginx -t
systemctl restart nginx

2.创建php测试文件

<?php
    $servername = "localhost";
    $username = "root";
    $password = "123";

    // 创建连接
    $conn = mysqli_connect($servername, $username, $password);
    
    // // 检测连接
    if (!$conn) {
        die("Connection failed: " . mysqli_connect_error());
