vi /usr/lib/systemd/system/rocketmq_exporter.service

② 复制下面内容至rocketmq_exporter.service，保存退出（ansible脚本templates需要这个模板文件）

将namesrvAddr 配置成变量替换

[Unit]
Description=rocketmq-exporter
After=network.target
[Service]
Type=forking
User=root
ExecStart=/root/java/jdk1.8.0_181/bin/java -jar /root/rocketmq-exporter/rocketmq-exporter-0.0.2-SNAPSHOT-exec.jar --rocketmq.config.namesrvAddr=192.168.244.133:9876
ExecStop=kill -9 pid
Restart=on-failure
[Install]
WantedBy=multi-user.target

java -jar /root/rocketmq-exporter/rocketmq-exporter-0.0.2-SNAPSHOT-exec.jar --rocketmq.config.namesrvAddr=192.168.244.133:9876

sleep 3s
echo 'start rocketmq exporter ok'
