我已经在/opt/kafka目录下下载了Kafka。我创建了一个名为的用户kafkaadmin并将其添加到wheel组中，以便他可以作为root用户运行。现在，我已将 Zookeeper 配置为 systemd 服务，并创建了一个名为zookeeper.serviceunder 的文件/etc/systemd/system/zookeeper.properties。下面是配置
[Unit]
Requires=network.target remote-fs.target
After=network.target remote-fs.target
[Service]
Type=simple
User=kafkaadmin
ExecStart=/opt/kafka/bin/zookeeper-server-start.sh -daemon /opt/kafka/config/zookeeper.properties
ExecStop=/opt/kafka/bin/zookeeper-server-stop.sh
Restart=on-abnormal
[Install]
WantedBy=multi-user.target
当我运行systemctl start zookeeper然后运行时，journalctl -u zookeeper我收到一条消息，说明服务已退出

现在，当我尝试运行时，systemctl start zookeeper出现上述错误。这kafkaadmin是 root 用户。我如何才能启动该用户的服务？我哪里错了？
