CentOS 8 Systemctl找不到服务

Question

systemctl start adstichr Failed to start adstichr.service: Unit adstichr.service not found.

所以我在里面做了以下代码

/etc/systemd/system

adstichr.service

[Unit]
Description=AdStichr Player
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=always
RestartSec=1
User=root
WorkingDirectory=/home/adstichrplayer
ExecStart=/usr/bin/node app.js
ExecStop=/bin/kill -INT $MAINPID


[Install]
WantedBy=multi-user.target

但是，当我运行它时，找不到它。想知道如何使其在我的ubuntu服务器上正常工作。
