我正在 CentOS 7 上运行 minecraft 服务器，并使用此 systemd 服务在崩溃时重新启动它。
服务配置位于/etc/systemd/system/my_minecraft_server.service：
[Unit]
Description=my_minecraft_server
[Service]
Type=simple
WorkingDirectory=/home/my_user/my_server/
ExecStart=/home/my_user/my_server/start.sh
User=my_user
Restart=always
Sockets=my_minecraft_server.socket
StandardInput=socket
StandardOutput=journal
StandardError=journal
[Install]
WantedBy=multi-user.target
套接字配置位于/etc/systemd/system/my_minecraft_server.socket：
[Unit]
PartOf=my_minecraft_server.service
[Socket]
ListenFIFO=%t/my_minecraft_server.stdin
但在 CentOS 9 上，这不起作用：
$ sudo systemctl start my_minecraft_server.service
Job for my_minecraft_server.service failed because of unavailable resources or another system error.
See "systemctl status my_minecraft_server.service" and "journalctl -xeu my_minecraft_server.service" for details.
的输出systemctl status my_minecraft_server.service是：
$ systemctl status my_minecraft_server.service
× my_minecraft_server.service - my_minecraft_server

我不知道为什么会失败。start.sh如果我手动运行脚本，它会正确运行。为什么我的服务不再工作了？
