# vps-manager 自动更新脚本（由 systemd timer 定时触发）
|
||
# 1. 自动同步 deploy/ 下的 systemd 单元文件（有变更才拷贝 + daemon-reload）
|
||
# 2. 从 Gitea 拉取最新代码，如有更新则装依赖并重启服务
|
||
#
|
||
# 可配置项（环境变量）：
|
||
# VPS_MANAGER_DIR 项目根目录（默认 /opt/vps-manager）
|
||
# VPS_MANAGER_SVC systemd 服务名（默认 vps-manager）
|
||
# GIT_BRANCH 跟踪的远端分支（默认 main）
|
||
#
|
||
# 使用示例：
|
||
# VPS_MANAGER_DIR=/srv/vps ./update.sh
|
||
# 或在 systemd unit 中设置 Environment=VPS_MANAGER_DIR=/srv/vps
