php - mysqli connect() 使用 IP 地址时收到错误消息

Question

我直接从 php.net 上下载了这个

$mysqli = new mysqli("localhost", "user", "password", "database");
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
echo $mysqli->host_info . "\n";

$mysqli = new mysqli("127.0.0.1", "user", "password", "database", 3306);
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

echo $mysqli->host_info . "\n";

我的输出是这样的:

通过 UNIX 套接字的本地主机

我的问题是...为什么当我尝试使用第二种方法时会收到错误消息。

Failed to connect to MySQL: (1045) Access denied for user '*'@'127.0.0.1' (using password: YES)

Answer 1

确保配置文件中注释掉了跳过网络。另请查看您的用户表，看看是否允许“用户”从 127.0.0.1 连接
