我用sasl+acl和kafka设置了kafka和zookeeper身份验证，并通过ssl双向身份验证（包括加密）将其发送给生产者和消费者。
通过在kafka和zookeeper之间启用sasl和acl，它不允许未经授权的kafka代理登录zookeeper集群。但是，主题的创建和删除可以不受任何限制地完成。

zookeeper\ u jaas.conf文件

Server {
        org.apache.zookeeper.server.auth.DigestLoginModule required
        username="admin"
        password="abc123"
        user_admin="abc123";
};

QuorumServer {

};

QuorumLearner {
        org.apache.zookeeper.server.auth.DigestLoginModule required
        username="admin"
        password="abc123";

按以下代码设置acl

final CountDownLatch connectedSignal = new CountDownLatch(1);
        String connect = "localhost:15300";
        ZooKeeper zooKeeper = null;

        try
        {
            String userName = "admin";
            String password = "mit123";

            zooKeeper = new ZooKeeper(connect, 5000, we ->
            {
                if (we.getState() == Watcher.Event.KeeperState.SyncConnected)
                {
                    connectedSignal.countDown();
                }
            });

            connectedSignal.await();

            zooKeeper.addAuthInfo("digest", (userName + ":" + password).getBytes());

            final String aclString = "auth:" + userName + ":" + password + ":" + "cdrwa" + 
            ",sasl:" + userName + ":" + "cdrwa";

            zooKeeper.setACL("/", parseACLs(aclString), -1);

        } finally
        {
            if (zooKeeper != null)
            {
                zooKeeper.close();
            }
        }

上面的代码正在工作，下面是执行代码后的结果。

在启动时，我替代了server.properties文件覆盖了kafka属性*

Kafka到生产者/消费者的认证工作正常，zookeeper到Kafka的认证工作正常。但是，主题的创建和删除也可以由未经授权的用户完成。
主题创建

kafka/bin/kafka-topics.sh --create --zookeeper localhost:15300 --replication-factor 3 --partitions 8 --topic test

主题删除

kafka/bin/kafka-topics.sh --zookeeper localhost:15300 --delete --topic test

注意：在创建或删除主题时，我没有设置-djava.security.auth.login.config=kafka\u server\u jaas.conf。所以这个操作应该受到限制。但事实上，事实并非如此。
帮助我仅为授权用户创建和删除主题。
