- bootstrap.sh: 支持 --env-file/--restore 位置参数(经 sudo bash -s 透传, 避免 sudo 清空环境变量导致参数丢失) - install/upgrade/rollback: 切换版本后软链生产 .env 到 current/.env, 兜底 compose env_file 相对目录解析; 沿用 .env 时校验 DB_DATA_DIR/ENV_FILE

# rollback.sh — 服务器回滚脚本
|
|
# 回滚 = ① 恢复数据到指定备份点(可选) + ② 代码切回历史版本。
|
|
#
|
|
# 用法:
|
|
# sudo ./deploy/rollback.sh # 交互式: 选择代码版本 + 是否恢复备份
|
|
# sudo ./deploy/rollback.sh --version <版本目录名> # 指定代码版本
|
|
# sudo ./deploy/rollback.sh --restore <备份包> # 仅恢复数据(不切代码)
|
|
#
|
|
# 说明:
|
|
# - 升级失败时 upgrade.sh 已自动回滚代码; 若需要把数据也回退到升级前,
|
|
# 用 --restore 指定 upgrade.sh 在 /opt/csctalon/backups 生成的备份包。
|
|
# - 数据恢复是"恢复到备份时间点", 备份之后的增量数据会丢失, 执行前请确认。
