@"wenchao"#p8828 提供一下 halo.service

@"wenchao"#p8839 用你 halo.service 里 ExecStart= 后面那段启动测试，不要用java -jar

systemctl start halo启动的时候报错。

跪求大佬帮忙，第一次加入大家的伙伴圈。

先停掉，然后用 java -jar 的方式启动会这样吗？

用java-jar 启动就是正常的。网页也能访问。

wenchao 提供一下 halo.service

wenchao User=halo

你这里用的 halo 账户，但是你用 java -jar 运行的时候是 root 账户，两者用到的工作目录是不一样的，你得确认一下。

wenchao

Ryan Wang 👍
我切换到halo用户运行java -jar也是可以得

用ExecStart= 后面的也能成功。
