如何通过systemd管理kafka经纪人？
[英]how to manage kafka broker by systemd?
问题描述
I am trying to manager kafka broker by systemd. 
我正在尝试通过systemd来管理kafka经纪人。 here is a unit-file: 这是一个单位文件：
[Unit]
Description=Kafka with broker id (%i)
After=network.target
After=zk.service
[Service]
Type=simple
SyslogIdentifier=kafka (%i)
WorkingDirectory=/opt/service/kafka_2.11-0.9.0.1
LimitNOFILE=16384:163840
ExecStart=/usr/bin/bash -c 'bin/kafka-server-start.sh /opt/service/units/kafka/%i.properties'
ExecStop=/usr/bin/bash -c 'bin/kafka-server-stop.sh /opt/service/units/kafka/%i.properties'
[Install]
WantedBy=multi-user.target
with that file, I can start kafka by command systemctl --user start kafka@0.service and systemctl --user start kafka@1.service . 有了该文件，我可以通过命令systemctl --user start kafka@0.service和systemctl --user start kafka@1.service 。
But when I try to kill those daemons by systemctl --user stop kafka@0.service , all two daemons are stoped! 但是，当我尝试通过systemctl --user stop kafka@0.service杀死那些守护程序时，所有两个守护程序都systemctl --user stop kafka@0.service ！ so, why could not I kill just only one broker? 因此，为什么我不能只杀死一位经纪人？

Something like this: 像这样：
[Unit]
Description=Kafka with broker id (%i)
After=network.target
After=zk.service
[Service]
Type=forking
SyslogIdentifier=kafka (%i)
Restart=on-failure
LimitNOFILE=16384:163840
ExecStart=/opt/service/kafka_2.11-0.9.0.1/bin/kafka-server-start.sh -daemon /opt/service/units/kafka/%i.properties
[Install]
WantedBy=multi-user.target
