2. Docker-compose 部署达梦 DM8 数据库
3. 配置 dm.ini 文件
4.完整的 dm.ini 文件
最近，将 MySQL 数据库迁移到了达梦 DM8 数据库。本文将分享如何通过 Docker-compose 部署达梦 DM8 数据库的过程，包括 Docker 镜像的获取与上传、配置文件的设置以及参数的调整。
1. 获取达梦 DM8 Docker 镜像并上传到 Harbor 服务器
首先，需要从达梦官网下载达梦8的 Docker 镜像：达梦下载页面。下载完成后，将离线镜像加载并推送至自己的 Harbor 服务器，以便使用 Docker-compose 进行管理。
2. Docker-compose 部署达梦 DM8 数据库
下面是 Docker-compose 配置文件 docker-compose.yml 的内容，定义了达梦 DM8 数据库的基本运行环境和参数：
version: '3'
services:dm8:image: xxx(填写你自己的镜像地址)/dm8:20240715container_name: dm8restart: alwaysprivileged: trueenvironment:CASE_SENSITIVE: 0 # 是否区分大小写，0 表示不区分，1 表示区分LD_LIBRARY_PATH: /opt/dmdbms/binPAGE_SIZE: 16EXTENT_SIZE: 32LOG_SIZE: 1024UNICODE_FLAG: 1INSTANCE_NAME: dm8_testports:- "30236:5236"volumes:- ./conf/dm.ini:/opt/dmdbms/conf/dm.ini- ./data:/opt/dmdbms/data- CASE_SENSITIVE： 设置为
0表示不区分大小写，这样可以与现有项目代码兼容。由于原先 MySQL 的字段是小写的，而达梦 DM8 默认使用大写字段名称，所以禁用大小写区分有助于减少迁移过程中的额外工作量。 - volumes： 挂载
dm.ini配置文件和数据目录，确保在容器重启后数据不会丢失。
3. 配置 dm.ini 文件
为了保证与 MySQL 的兼容性，主要需要调整 dm.ini 配置文件中的以下参数：
COMPATIBLE_MODE=4 # 兼容 MySQL 模式此配置项将达梦 DM8 数据库设置为兼容 MySQL 的模式，从而避免代码修改，提升迁移效率。
