DM7主备升级方案

背景：

测试一下V7.6.0.186-Build(2021.08.31-144731)主备滚动升级到DB Version: 0x7000a。

一搭建主备

搭建守护集群，过程省略。

SQL1为主，SQL2为备。

查看数据库版本

二滚动升级

2.1 备库升级

2.1.1 备份bin目录

|---------------------------------------|
| cd dmdbms tar -zcvf /tmp/bin_bak1 bin |

2.1.2 关闭进程

关闭实例、守护、APservice

|-------------------------------------------------|
| ./dmwatcherd stop ./dmserverd stop ./dmapd stop |

2.1.3 目录替换

由于本次测试使用的key存在问题，不支持主备，因此选择将当前的dm.key移除

|----------------|
| mv dm.key /tmp |

将新版本的bin目录拷贝替换原来的bin目录

|-------------------------------------------------------|
| cd dm7new/bin \cp -a -r * /home/dmdba/dm/dmdbms/bin |

2.1.4 重启进程

使用新的bin启动进程

|----------------------------------------------------|
| ./dmwatcherd start ./dmserverd start ./dmapd start |

上述为正常现象。

2.1.5 主备切换
