我在 Red Hat Enterprise Linux Server 7.9 (Maipo) 上有这个 systemd 服务
[Unit]
Description = EUM Server Service
PartOf=eum.service
# Start this unit after the app.service start
After=eum.service
After=eum-db.service
[Service]
Type=forking
User=root
WorkingDirectory=/prod/appdynamics/EUMServer/eum-processor/
ExecStart=/usr/bin/sleep 45 && /bin/bash bin/eum.sh start
RemainAfterExit=true
ExecStop=/bin/bash bin/eum.sh stop
[Install]
WantedBy=multi-user.target
失败是因为它试图选择之后的所有内容/usr/bin/sleep作为该命令的参数。我只想执行/usr/bin/sleep 45并成功执行bin/eum.sh start。我怎样才能让它发挥作用？

命令行没有提供给 shell，所以&&无效。例如，您需要
ExecStart=/bin/bash -c 'sleep 45 && /bin/bash bin/eum.sh start'
或者你可以将命令分成
ExecStartPre=/usr/bin/sleep 45
ExecStart=/bin/bash bin/eum.sh start
