[解决了]
我的问题很简单
我创建了一个 mcboot.service 来自动启动我的所有 Mod 8 MC 服务器，我 sysctl 启用了它，并做了 daemon-reload，我现在的问题是，我可以使用名为“agent”的用户手动执行 run.sh，但在自动启动时我在 sysctl 状态上得到了这个：
agent@ubntsrv1: /var/ATM8$ systemctl daemon-reload
==== AUTHENTICATING FOR org.freedesktop.systemd1.reload-daemon === Authentication is required to reload the systemd state.
Authenticating as: user (agent)
Password:
==== AUTHENTICATION COMPLETE ===
agent@ubntsrv1: /var/ATM8$ systemctl status mcboot.service
mcboot.service Minecraft boot script

Feb 02 11:14:20 ubntsrv1 systemd[1]: mcboot.service: Deactivated successfully.
agent@ubntsry1:/var/ATM8$
这是我的 run.sh 的内容：
#!/bin/env sh
# Forge requires a configured set of both JVM and program arguments.
# Add custom JVM arguments to the user_jvm_args.txt
# Add custom program arguments (such as noguil to this file in the next line before the "$@" or
# pass them to this script directly
BASEDIR=$(dirname "$0")
echo "$BASEDIR"
java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.19.2-43.2.3/unix_args.txt BASEDIR=$(dirname "$0")
echo "$BASEDIR"
这是我的 mcboot.service ：
[Unit]
Description=Minecraft boot script
[Service]
ExecStart=/var/ATM8/run.sh start
[Install]
WantedBy=multi-user.target
我想做正确的事情，我不想使用 crontab。
谢谢

当您从不同的目录手动运行脚本时，您的脚本是否有效，例如 cd /tmp; /var/ATM8/run.sh 启动吗？ （我想不是。）在 java 之前尝试 cd "$BASEDIR" ...
这实际上解决了我的问题！我可以从任何地方手动运行我的脚本，但实际上添加了cd $BASEDIR使该服务成功运行，现在每次我的 R820 重新启动时它都会运行！谢谢
