# 这是**模板**：deploy/install-linux.sh 会把 __NODE__ / __DIR__ / __USER__ 替换成真实值后
|
|||
|
|
# 安装到 /etc/systemd/system/classhelper.service。手动部署时直接改这三处即可：
|
|||
|
|
#
|
|||
|
|
# sudo sed -e 's#__NODE__#/usr/bin/node#' \
|
|||
|
|
# -e 's#__DIR__#/opt/classhelper#' \
|
|||
|
|
# -e 's#__USER__#classhelper#' \
|
|||
|
|
# deploy/classhelper.service | sudo tee /etc/systemd/system/classhelper.service
|
|||
|
|
# sudo systemctl daemon-reload && sudo systemctl enable --now classhelper
|
|||
|
|
#
|
|||
|
|
# 常用命令：
|
|||
|
|
# systemctl status classhelper
|
|||
|
|
# journalctl -u classhelper -f # 实时日志
|
|||
|
|
# systemctl restart classhelper # 重启（改完 .env 需要）
