命令行工具部署达梦数据库 DMDPC(BP 多副本架构)

解达梦数据库DPC集群的主要使用场景:

DMDPC 关注和解决的是大数据、计算与存储分离、高可用、支持全部的 SQL 标准、拥有完整的事务处理能力和集群规模能够动态伸缩的业务场景:

  1. 大量的复杂查询操作要求优化器能够生成优良的执行计划,并且执行引擎能够充分利用多机器、多核的硬件资源
  2. 某些行业对数据一致性和多副本备份容灾有较高要求,同时希望维护成本足够低和故障恢复时间足够短;
  3. 用户的业务规模有峰值,要求所需的机器资源能够灵活地添加和删除。

DPC架构:

一个完整的 DMDPC 架构由计划生成节点 SP、数据存储节点 BP 和元数据服务器节点 MP 三部分组成。

  • SP 对外提供分布式数据库服务,用户可以登录到任意一个 SP 节点,获得完整的数据库服务,SP 节点不存储数据,配置成单机即可。
  • BP 负责存储数据,执行 SP 的调度指令并将执行结果返回给 SP。
  • MP 负责存储元数据并向 SP、BP 提供元数据服务。
    MP 和 BP 节点既可以配置成单机,也可以配置成多副本系统。其中每一个多副本系统中只有一个作为主节点,其余节点均作为备份节点。

1 集群规划

DMDPC 集群规划部署 1 个 SP,2 个 BP 和 1 个 MP。
MP 采用单机模式,BP 采用多副本模式,每个 BP 配置 2 个副本。

2 初始化数据库实例

根据集群规划,初始化 8 个实例,分别为 SP、MP 和 6 个 BP 角色。

将 MP.INI 文件内容分别写入 SP(SP1)、两个 RAFT 组内的所有 BP(BP11、BP12、BP13、BP21、BP22、BP23)和 MP 中。

4 启动 MP

注意相关端口是否被占用,涉及相关的服务器,防火墙是否关闭或者是否将相关端口加入到白名单。
如果端口没被占用,持续报端口的错误,
ps -ef|grep dmdba
kill掉相关的进程,再重新启动

7 配置 BP11

1: 配置 BP11 的 dm.ini

ARCH_INI = 1   #打开归档配置

2: 配置 BP11 的本地归档 dmarch.ini。此处先只配本地归档,避免提前发起 RAFT 选举

[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL #本地归档类型
ARCH_DEST =/dmdata/dpc_data/bp11/DAMENG/arch  #本地归档文件路径
ARCH_FILE_SIZE = 128   #本地单个归档文件最大值,单位MB
ARCH_SPACE_LIMIT = 0   #本地归档文件总大小,0表示无限制

3:正常启动 BP11 到 Open 状态

11 配置 BP dm.ini

RAFT_1 组各实例(BP11、BP12、BP13)和 RAFT_2 组各实例(BP21、BP22、BP23)中 dm.ini 文件的配置方法完全相同。

下面以 BP11 的 dm.ini 为例进行介绍。dm.ini 文件配置如下:

ARCH_INI = 1   #打开归档配置
ALTER_MODE_STATUS = 0   #不允许用户直接通过SQL语句修改服务器模式

12 配置 BP RAFT _1归档文件

修改 DMARCH.INI,配置 RAFT 归档与本地归档。RAFT_1 组配置如下:
1: 配置 BP11 归档文件 DMARCH.INI

XMAL_HB_INTERVAL = 5   #节点通信检测间隔
RAFT_HB_INTERVAL = 150   #选举心跳间隔
RAFT_VOTE_INTERVAL = 1500  #选举超时时间,三个库设置不同以尽快选出主库
RAFT_SELF_ID = 1   #多副本自身节点ID

[ARCHIVE_RAFT1]
ARCH_TYPE = RAFT   #RAFT归档
ARCH_DEST = BP12  #归档目标实例名
ARCH_DEST_ID = 2   #归档目标多副本节点ID

[ARCHIVE_RAFT2]
ARCH_TYPE = RAFT   #RAFT归档
ARCH_DEST = BP13   #归档目标 实例名
ARCH_DEST_ID = 3   #归档目标多副本节点ID

[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL #本地归档类型
ARCH_DEST =/dmdata/dpc_data/bp11/DAMENG/arch  #本地归档文件路径
ARCH_FILE_SIZE = 128   #本地单个归档文件最大值,单位MB
ARCH_SPACE_LIMIT = 0   #本地归档文件总大小,0表示无限制

2.配置 BP12 归档配置文件 DMARCH.INI

14 启动 SP 和 RAFT 组内所有 BP

启动 SP 和 BP 没有先后之分。

./dmserver path=/dmdata/dpc_data/sp1/DAMENG/dm.ini dpc_mode=sp
./dmserver /dmdata/dpc_data/bp11/DAMENG/dm.ini  dpc_mode=bp mount
./dmserver /dmdata/dpc_data/bp12/DAMENG/dm.ini  dpc_mode=bp mount
./dmserver /dmdata/dpc_data/bp13/DAMENG/dm.ini  dpc_mode=bp mount
./dmserver /dmdata/dpc_data/bp21/DAMENG/dm.ini  dpc_mode=bp mount
./dmserver /dmdata/dpc_data/bp22/DAMENG/dm.ini  dpc_mode=bp mount
./dmserver /dmdata/dpc_data/bp23/DAMENG/dm.ini  dpc_mode=bp mount
