# ============================================================
|

# dump_mysql_schema.sh
|
||||
# ------------------------------------------------------------
|
||||
# 导出 MySQL 整库（或指定库）的纯 DDL 到 stdout。
|
||||
# 目的：把线上生产数据库的"表结构"抓回来，与 docs/sql/init_database.sql 做 diff。
|
||||
#
|
||||
# 适用场景（任选其一）：
|
||||
# 1) 宿主机直接执行（远程 MySQL 同样可用，只要本机能连过去）
|
||||
# 2) 容器内执行：
|
||||
# docker exec -i txw-mysql bash -s < devops/dump_mysql_schema.sh \
|
||||
# > prod_schema_$(date +%Y%m%d).sql
|
||||
#
|
||||
# 用法示例（远程库）：
|
||||
# MYSQL_HOST=192.168.110.55 MYSQL_PORT=3306 \
|
||||
# MYSQL_USER=root MYSQL_PWD='your_password' \
|
||||
# INCLUDE_DBS=qyd_txw \
|
||||
# bash devops/dump_mysql_schema.sh > qyd_txw_schema_$(date +%Y%m%d).sql
|
||||
#
|
||||
# 可调环境变量（全部可选）：
|
||||
# MYSQL_HOST 远端/本机地址（默认 localhost）
|
||||
# MYSQL_PORT 端口（默认 3306）
|
||||
# MYSQL_USER 用户名（默认 root）
|
||||
# MYSQL_PWD 密码（推荐用单引号包裹，避免 $、! 等被 bash 解释）
|
||||
# INCLUDE_DBS 只导指定库，多个用逗号分隔；留空=全部业务库
|
||||
# EXCLUDE_DBS 排除的库（默认：information_schema,performance_schema,mysql,sys）
|
||||
# ============================================================
