2.3 DEM快速部署主备集群
2.3.1 引言
平时凭借传统部署手段（准备dmmal,dmarch,dmwatcher,dmmonitor参数文件，并且里面的参数众多，记忆有限，对自己来说顾名思义即可），操作步骤繁琐。
倘若让我们批量部署主备集群，因节点数据量多，参数多，也因枯燥重复的步骤，往往令人恼火，犯一些小错误，导致不可轻易发现的小问题，耗时巨久。
故此处引入DEM工具快速便捷部署主备集群的案例。
2.3.2 集群前期规划
2.3.2.1 IP规划
2.3.2.2 端口规划
2.3.2.3 存储规划
2.3.2.4 数据库初始化参数规划
2.3.3 部署DEM企业管理器
(略)
参考文档 ：搭建DEM企业管理器
2.3.4 安装dmagent代理
在即将被部署的主机上安装dmagent代理程序，并启动dmagent服务，托管于DEM。
PS:
- 被部署集群的主机，强烈建议以root用户启动代理服务。
- 保证dem和dmagent版本一致，两端系统时间同样也要一致，否则会出现无法显示主机信息等情况。
### 1. 从DEM服务器端获取dmagent代理程序，并调整center.url指向到DEM.
[root@dca01 dmagent]# vim config.properties
##[General]
##run_mode values:
##0 - assist process
##1 - assist process & monitor
##2 - assist process & monitor & deployer
run_mode=2
##id_gen_policy values:
##0: mac&ip, mac preferred
##1: ip
id_gen_policy=0
ap_port=6363
rmi_port=6364
##[DEM]
center.url=http://192.168.0.120:8080/dem
center.agent_servlet=dem/dma_agent
### 2. 客户端：192.168.0.10/11/12 远程拷贝dmagent目录

If zipfile and list are omitted, zip compresses stdin to stdout.

2.3.6 测试主备集群故障自动切换
正常情况下，DEM截图主备库状态
2.3.6 总结
达梦DEM平台可操作有限，但对于我们做普通操作足够。它主要整合manager管理工具、 SQL调试器、数据迁移工具。
对我本人而言，最关注的集群部署、数据库监控，非常方便快速地部署成百上千的集群，还能利用数据库监控做数据库巡检，结合AWR报告做性能分析。
最后一点是很多人不想在自己电脑上安装过多的客户端软件，可以通过DEM远程调用迁移工具、manager工具。
令惋惜的是：如果一个节点主机上部署两套主备，它会拷贝两次数据库软件，重复的软件还是有点占用磁盘空间（释放完后1.2GB），所以这点需注意。后期有空，我再出数据文件迁移文章，弥补这问题的缺陷。
