java - 在 ignite 中启用身份验证

问题描述

我正在运行此代码，我想在 apache ignite 2.7.6 中启用身份验证。它仍然显示authentication = off

如何启用身份验证？

public static void main(String[] args) throws ClientException, Exception {
    Class.forName("com.mysql.jdbc.Driver");
    Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/ignite_sample","root","99@Jj");
    // Apache Ignite node configuration.
    IgniteConfiguration cfg = new IgniteConfiguration();

    // Ignite persistence configuration.
    DataStorageConfiguration storageCfg = new DataStorageConfiguration();

    // Enabling the persistence.
    storageCfg.getDefaultDataRegionConfiguration().setPersistenceEnabled(true);

    // Applying settings.
    cfg.setDataStorageConfiguration(storageCfg);

    // Enable authentication
    cfg.setAuthenticationEnabled(true);

    Ignite ignite = Ignition.start(cfg);
}

解决方案

我猜这是因为您尝试在服务器节点启动之前创建连接。

接下来试试：

1）使用 authenticationEnabled=true 和 persistenceEnabled=true 启动服务器（默认区域）

2）然后运行下一个：

// Register JDBC driver.
Class.forName("org.apache.ignite.IgniteJdbcThinDriver");

// Open the JDBC connection.
try (Connection conn = DriverManager.getConnection("jdbc:ignite:thin://127.0.0.1:10800?" +
    "user=client&password=password"))
{
    conn.createStatement().executeQuery("select 1");
    System.out.println("Done");
}
catch (SQLException e) {
    e.printStackTrace();
    }
