如何通过systemd管理kafka经纪人？

Question

我试图通过systemd管理kafka经纪人.这是一个单元文件:

[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

与该文件,我可以通过命令启动卡夫卡systemctl --user start kafka@0.service和systemctl --user start kafka@1.service.

但是当我试图杀死那些守护进程时systemctl --user stop kafka@0.service,所有两个守护进程都停止了!所以,为什么我不能只杀死一个经纪人呢？

像这样的东西:

[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
