数据库介绍

1.1 版本说明

本次安装使用opengauss数据库的LTS版本 5.0.0，版本分为X86_64和AARCH64两个架构，安装建议使用当前最新LTS版本。

OpenGauss 5.0.0 双机安装及ora2pg的使用-1

1.2 架构介绍

1.2.1 数据库openGauss支持单机部署和一主多备部署两种部署形态

单机指的是只有一个数据库实例。
双机指的是系统中存在主备数据库实例，主实例支持读写，备实例支持只读。
一主多备指的是在系统存在一个主机，多个备机，openGauss最多支持8个备机。

冷备份：是指备份就是一个简单的备份集，不可以提供服务。

热备份：是指备份实例可以对外提供服务。

1.2.2 部署形态汇总

部署形态

技术方案

高可用

基础设置要求

业务场景

场景特点

技术规格

单机

无高可用能力

单机房

物理机

对系统的可靠性和可用性无任何要求

主要用于体验试用以及调测场景

系统RTO和RPO不可控

无实例级容灾能力，一旦出现实例故障，系统不可用

一旦实例级数据丢失，则数据永久丢失，无法恢复

主备

主机+备机

抵御实例级故障

单机房

物理机

节点间无网络延迟

要求承受实例级故障

适用于对系统可靠性要求不高的场景

2.8 创建XML配置文件

需要提前创建安装时使用的配置文件，配置文件里有对应命名和目录结构参数配置。

omm@host-02[~]cat cluster_config.xml 

2.9 节点配置互信

配置两个节点omm用户的互信。

2.10 安装前检查

预检查通过后，可以进行下一步安装动作。

2.11 执行安装

指定参数启动数据库，内存、进程和字符集等参数，主节点执行即可。

gs_install -X /home/omm/cluster_config.xml --gsinit-parameter="--encoding=UTF8" --dn-guc="max_process_memory=4GB" --dn-guc="shared_buffers=256MB" --dn-guc="bulk_write_ring_size=256MB" --dn-guc="cstore_buffers=16MB"

Successfully installed application. end deploy.. omm@host-01[~]

2.12 状态检查

安装完成后执行gs_om命令检查状态。

omm@host-01[/opt/opengauss/install/app/bin]gs_om -t status --detail [ Cluster State ] cluster_state : Normal redistributing : No current_az : AZ_ALL [ Datanode State ] node node_ip port instance state ---------------------------------------------------------------------------------------------------------- 1 host-01 11.11.xx.183 15400 6001 /opt/opengauss/install/data/dn P Primary Normal 2 host-02 11.11.xx.184 15400 6002 /opt/opengauss/install/data/dn S Standby Normal

2.13 备库只读

设置备库只读。

1）如果主备机上的openGauss数据库实例正在运行，请先分别停止主备机上的数据库实例。

2）分别打开主机与备机的postgresql.conf配置文件，找到并将对应参数修改为：

wal_level=hot_standby hot_standby = on hot_standby_feedback = on

3）参数max_standby_streaming_delay、 max_prepared_transactions、 max_standby_archive_delay、 hot_standby_feedback可以参考《数据库参考》按需进行设置。

4）修改完成后，分别启动主备机即可。

2.14 取消public 权限

创建用户后，取消public权限，同时创建一个与用户名相同的schema，创建对象默认放到该schema下。

revoke all on schema public from public; create user user1 login identified by "passwd1"; grant all privileges on database db1 to user1;

2.15 高可用切换测试

进行主备切换测试，以及主备故障恢复测试。

数据迁移（ora2pg）

3.1 安装ora2pg

yum install perl-ExtUtils-CBuilder yum install perl-ExtUtils-MakeMaker yum install perl-CPAN rpm -ivh oracle-instantclient19.11-basic-19.11.0.0.0-1.x86_64.rpm rpm -ivh oracle-instantclient19.11-devel-19.11.0.0.0-1.x86_64.rpm rpm -ivh oracle-instantclient19.11-jdbc-19.11.0.0.0-1.x86_64.rpm rpm -ivh oracle-instantclient19.11-sqlplus-19.11.0.0.0-1.x86_64.rpm export ORACLE_HOME=/usr/lib/oracle/19.11/client64/

#安装DBI，DBD::Oracle，DBD::Pg ，在 www.cpan.org/modules/by-module 进行下载，版本选择最近版本。

DBD-Oracle-1.83.tar.gz
DBI-1.643.tar.gz
DBD-Pg-3.18.0.tar.gz

#在安装前需要设置环境变量：

export ORACLE_HOME=/usr/lib/oracle/19.11/client64/ export GAUSSHOME=/opt/opengauss/install/app/ export C_INCLUDE_PATH=/opt/opengauss/install/app_a07d57c3/include/p ostgresql/server/libpq/:/opt/opengauss/install/app_a07d57c3/include/postgresql/server/

#分别解压后，执行：

perl Makefile.PL make && make install

# 安装JSON：

JSON-4.10.tar.gz perl Makefile.PL make && make install

## 源码安装：

perl Makefile.PL make && make install export PERL5LIB=/home/omm/software/ora2og/openGauss-tools-ora2og-master/ export PATH=$PATH:/usr/local/bin/ ora2pg --help root@host-01[/home/omm/software]ora2pg -v Ora2Pg v21.1

3.2 软件环境检查

使用下面提供的脚本检查当前安装组件是否正确。

vi check.pl #!/usr/bin/perl use strict; use ExtUtils::Installed; my $inst=ExtUtils::Installed->new(); my @modules=$inst->modules(); foreach(@modules) { my $ver = $inst->version($_)||"????"; printf("%-12s -- %s\n", $_, $ver); } exit; root@host-01[/usr/local/bin]perl check.pl DBD::Oracle -- 1.83 DBD::Pg -- 3.18.0 DBI -- 1.643 JSON -- 4.10 Ora2Pg -- 21.1 Perl -- 5.28.3 RRDs -- 1.6999

3.3 项目初始化

Ora2pg可以针对每次迁移任务创建一个逻辑项目，项目下有对应目录存放迁移过程中的数据和文件。

root@host-01[/home/omm/ora2pg]ora2pg --init_project dir1

Creating project dir1. ./dir1/ schema/ dblinks/ directories/ functions/ grants/ mviews/ packages/ partitions/ procedures/ sequences/ synonyms/ tables/ tablespaces/ triggers/ types/ views/ sources/ functions/ mviews/ packages/ partitions/ procedures/ triggers/ types/ views/ data/ config/ reports/ Generating generic configuration file Creating script export_schema.sh to automate all exports. Creating script import_all.sh to automate all imports.

3.4 编辑配置文件
