Apache kafka 无法在CentOS 7上启动Kafka Connect作为服务

我有一个卡夫卡环境（Zookeeper+卡夫卡服务器+卡夫卡连接），当我在CentOS 7上使用命令行启动每个单独的组件时，它可以完美地运行

现在，我将这些Kafka组件设置为作为服务运行。为此，我创建了.service文件并将其放置在/etc/systemd/system文件夹中。以下是文件

Zookeeper和Kafka服务开始时没有任何问题。我可以创建主题，然后对主题执行操作。问题在于卡夫卡连接服务

当我尝试使用systemctl命令启动服务时，该服务不会启动。它被卡住了，没有以下日志：：

Oct 19 18:29:20 localhost.localdomain connect-distributed.sh[1071]: [2018-10-19 18:29:20,713] INFO Added plugin 'io.debezium.connector.mysql.MySqlConnector...er:136)

我在这一行之后的消息日志中找不到此进程的任何日志，并且在任何其他日志中都没有错误。进程卡在这一行上：：

信息注册加载程序：PluginClassLoader{pluginLocation=file…er:207）

无论我增加多少超时时间，这个过程都不会启动。但是当我从命令行运行相同的命令时，服务会正常启动

我尝试从插件路径中删除所有连接器，以查看服务是否启动，但它卡在同一条线上

以下是我的参考点：

**下面的配置在Ubuntu中对我有效**

[单位]
Requires=kafka.service
之后=卡夫卡服务

[服务]

用户=卡夫卡

重启=出现异常

我在Debain 9上遇到了同样的问题。我发现这是因为服务需要一个

工作目录

，否则kafka connect永远无法完全充电

因此，您的服务应该如下所示：

WorkingDirectory=“/opt/InteracticCRM/kafka_2.11-1.0.1”不清楚为什么不使用Confluent OSS提供的systemd文件（在安装了YUM之后）@cricket_007是的，这很管用。但是我仍然不知道为什么这个脚本不起作用！你能访问Connect服务器的
/connector插件吗？顺便说一下，你不应该在同一台机器上运行Connect、Zookeeper和Kafka
