一、前言
openGauss 6.0.0-RC1是openGauss 2024年3月发布的创新版本，该版本生命周期为0.5年。根据openGauss官网介绍，6.0.0-RC1与之前的版本特性功能保持兼容,另外，在和之前版本兼容的基础上增加了很多新功能，比如分区表性能优化、支持多语言日志、支持SPQ多机并行查询框架、MySQL迁移及兼容性增强、特别是为DataKit增加了很多新特性，并且修复了很多CVE漏洞。
https://docs-opengauss.osinfra.cn/zh/docs/6.0.0-RC1/docs/ReleaseNotes/版本介绍.html，官网这个页面对于openGauss 6.0.0-RC1对于版本继承和新增功能有详细的介绍。
在安装部署方面，openGauss 6.0.0提供了一站式交互式安装功能，极大简化了安装流程，降低了用户学习成本。
根据openGauss官网介绍，openGauss版本号采用点分位命名规则（XX.Y.0）模式，创新版在版本号后增加“-RCx”表示。其中XX.0.0表示LTS版本，Y表示补丁版本，XX.0.0-RCx表示创新版本。正常每两年发布一个LTS版本，创新版本供用户联创测试使用；LTS版本作为长期支持版本，可规模上线使用。涉及重大问题修复时，会按需发布补丁版本。
openGauss生命周期初步规划为：
- LTS版本发布间隔周期2年，社区提供3年维护支持。
- 创新版本发布间隔周期0.5年，社区提供0.5年维护支持。
之前我曾体验过openGauss 5.0的集群安装部署，这次我希望再尝试下6.0的安装部署，另外也希望通过一款名叫zcbus的迁移工具，迁移Oracle 数据到OpenGauss 6.0.0。

2.6.2 安装软件依赖包
openGauss 6.0.0的安装需要一些软件依赖包。
如果服务器可以联网，可通过配置yum源进行安装，若无法连接外网，可通过挂在iso文件，配置内部yum源进行安装。
# root用户执行【所有节点】
[root@xsky-nodexxx ~]# yum install -y libaio-devel flex bison ncurses-devel glibc-devel patch redhat-lsb-core readline-devel zlib readline
-- 检查是否已安装
[root@xsky-nodexxx ~]# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep -E "libaio-devel|flex|bison|ncurses-devel|glibc-devel|patch|redhat-lsb-core|readline-devel|zlib|readline|expect"
2.7 修改操作系统配置
2.7.1 关闭操作系统防火墙
建议对各安装节点关闭操作系统防火墙，若有特殊需求需要开启操作系统防火墙，可根据openGauss相关服务及协议，将相应IP和端口号添加至openGauss节点主机防火墙白名单中。
# root用户执行【所有节点】
-- 停止 firewalld 服务
[root@xsky-nodexxx ~]# systemctl stop firewalld.service
-- 禁用 firewalld 服务
[root@xsky-nodexxx ~]# systemctl disable firewalld.service
-- 查看 firewalld 服务状态
[root@xsky-nodexxx ~]# systemctl status firewalld
-- 显示如下表示已关闭禁用防火墙
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
2.7.2 关闭SELinux
通常会选择关闭操作系统selinux服务，可通过如下方式关闭各节点selinux服务。
# root用户执行【所有节点】
-- 临时关闭SELinux
[root@xsky-nodexxx ~]# setenforce 0
-- 永久关闭SELinux
[root@xsky-nodexxx ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
-- 检查SELinux状态
[root@xsky-nodexxx ~]# getenforce
-- 状态为Disabled表明SELinux已关闭
Disabled
2.7.3 修改字符集
建议将各数据库节点设置为相同字符集，比如，采用如下方式，设置字符集为UTF8。
# root用户执行【所有节点】
[root@xsky-nodexxx ~]# cat>> /etc/profile<<EOF
export LANG=en_US.UTF-8
EOF
[root@xsky-nodexxx ~]# source /etc/profile
-- 检查字符集
[root@xsky-nodexxx ~]# env |grep -i lang
2.7.4 设置时区和时间
各数据库节点应确保时区和时间一致，下面通过ntp方式设置时区，也可以通过chrony方式配置各节点时钟同步。
# root用户执行【所有节点】
# 使用ntp设置时钟同步
-- 安装ntp服务
[root@xsky-nodexxx ~]# yum install -y ntp
-- 开机启动ntp服务
[root@xsky-nodexxx ~]# systemctl enable ntpd
-- 启动ntp服务
[root@xsky-nodexxx ~]# systemctl start ntpd
-- 设置时区Asia/Shanghai
[root@xsky-nodexxx ~]# timedatectl set-timezone Asia/Shanghai
-- 检查时区
[root@xsky-nodexxx ~]# timedatectl |grep -i zone
-- 启用ntp服务
[root@xsky-nodexxx ~]# timedatectl set-ntp yes
-- 编辑定时任务列表
[root@xsky-nodexxx ~]# crontab -e
-- 使用vi/vim对定时任务列表进行编辑，添加如下内容变保存退出
0 12 * * * ntpdate cn.pool.ntp.org
-- 查看时间及时区
[root@xsky-nodexxx ~]# timedatectl status
2.7.5 修改硬件时钟
硬件时钟，也称为实时时钟，是独立的硬件设备(如电池、电容原件等)，一般服务器在开机时，操作系统向硬件时钟同步时间。
# root用户执行【所有节点】
-- 将当前系统时间写入硬件时钟
[root@xsky-nodexxx ~]# hwclock --systohc
-- 查看硬件时钟
[root@xsky-nodexxx ~]# hwclock
2.7.6 关闭SWAP分区
关闭swap交换内存是为了保障数据库的访问性能，避免把数据库的缓冲区内存淘汰到磁盘上。
# root用户执行【所有节点】
-- 禁用当前的 swap 分区
[root@xsky-nodexxx ~]# swapoff -a
# 永久关闭swap 分区
-- 使用vi/vim编辑 /etc/fstab 文件,注释如下内容
UUID=<swap_partition_uuid> swap swap defaults 0 0
-- 保存退出，下次重启会生效
2.7.7 设置root用户远程登陆
# root用户执行【所有节点】
[root@xsky-nodexxx ~]# cat >>/etc/ssh/sshd_config<<EOF
PermitRootLogin yes
EOF
-- 检查设置结果
[root@xsky-nodexxx ~]# cat /etc/ssh/sshd_config |grep PermitRootLogin
2.7.8 配置SSH
# root用户执行【所有节点】
-- 禁用 SSH 登录时的横幅（Banner）
[root@xsky-nodexxx ~]# sed -i '/Banner/s/^/#/' /etc/ssh/sshd_config
-- 目的是禁用允许以 root 用户登录的配置选项
[root@xsky-nodexxx ~]# sed -i '/PermitRootLogin/s/^/#/' /etc/ssh/sshd_config
[root@xsky-nodexxx ~]# echo -e "\n" >> /etc/ssh/sshd_config
[root@xsky-nodexxx ~]# echo "Banner none " >> /etc/ssh/sshd_config
# 修改Banner配置，去掉连接到系统时，系统提示的欢迎信息。欢迎信息会干扰安装时远程操作的返回结果，影响安装正常执行
[root@xsky-nodexxx ~]# echo "PermitRootLogin yes" >> /etc/ssh/sshd_config
[root@xsky-nodexxx ~]# cat /etc/ssh/sshd_config |grep -v ^#|grep -E 'PermitRootLogin|Banner'
-- 重启生效
[root@xsky-nodexxx ~]# systemctl restart sshd.service
-- 查看SSH状态
[root@xsky-nodexxx ~]# systemctl status sshd.service
2.7.9 添加hosts解析
# root用户执行【所有节点】
[root@xsky-nodexxx ~]# cat >> /etc/hosts<<EOF
10.110.7.39 xsky-node1
10.110.7.40 xsky-node2
10.110.7.41 xsky-node3
10.110.7.42 xsky-node4

| net.ipv4.tcp_sack | 启用有选择的应答，通过有选择地应答乱序接受到的报文来提高性能，让发送者只发送丢失的报文段（对于广域网来说）这个选项应该启用，但是会增加对CPU的占用。0表示关闭。1表示开启。 | 否 | 1 |
| net.ipv4.tcp_timestamps | TCP时间戳（会在TCP包头增加12节），以一种比重发超时更精确的方式（参考RFC 1323）来启用对RTT的计算，启用可以实现更好的性能。0表示关闭。1表示开启。 | 否 | 1 |
| vm.extfrag_threshold | 系统内存不够用时，linux会为当前系统内存碎片情况打分，如果超过vm.extfrag_threshold的值，kswapd就会触发memory compaction。所以这个值设置的接近1000，说明系统在内存碎片的处理倾向于把旧的页换出，以符合申请的需要，而设置接近0，表示系统在内存碎片的处理倾向做memory compaction。 | 否 | 500 |
| vm.overcommit_ratio | 系统使用绝不过量分配内存的算法时，系统整个内存地址空间不得超过swap+RAM值的此参数百分比，当vm.overcommit_memory=2时此参数生效。 | 否 | 90 |
| MTU | 节点网卡最大传输单元。OS默认值为1500，调整为8192可以提升数据收发的性能。 | 否 | 8192 |
重点是文件系统参数、transparent_hugepage设置、文件句柄设置、系统支持的最大进程数设置、网卡参数配置，可参照官网进行配置。

在规划的openGauss主节点/opt/software/openGauss目录下创建cluster_config.xml配置文件。
cluster_config.xml文件包含部署openGauss的服务器信息、安装路径、IP地址以及端口号等。用于告知openGauss如何部署。可根据不同场景配置对应的XML文件，如一主一备、一主一备一级联、一主二备等，本次安装部署为一主二备集群环境。

六、安装ZCBUS
6.1 zcbus介绍
zcbus是由首科软创(北京)软件有限公司[公司网址：http://www.zcbus.net/index.html]开发的一款基于实时增量数据捕获实现异构数据库数据交换同步的数据交换平台，可实现集中数据同步管理，为企业数据集中、分发、交换、清洗、加工等提供更为合理的解决方案。
目前zcbus支持多种数据库产品，包括oracle、MySQL、和一些开源数据库产品、目前也支持一些主流的国产数据库,如下所示，是当前zcbus所支持的一些软件信息。
6.2 zcbus下载
当前zcbus最新版本为2.0.1，可通过如下方式来下载最新安装包,zcbus提供了x86和arm两种版本，可根据实际操作系统选择下载对应的安装版本包。
另外zcbus也提供了单机版本和集群版本，本次选择单机版本进行安装。
单机运行环境的最低配置建议：
| 主机\交换服务器 | 1 台，ARM 或 X86、CPU 4 核、16GB 内存、存储不少于 50GB |
|---|---|
| 操作系统 | RedHat/CentOS 7（或麒麟） |
| 网络 | 数据交换服务器需要与共享的数据库或大数据平台保持网络畅通；如两者网络不畅通，可通过前置机跳转方式实现数据交换 |
| seLinux | 关闭 |
| 数据缓存周期 | 默认 30 天，可调整 |
| 数据交换规模 | 单机支持 1000 以内的数据表，1-5 条数据复制链路 |
可通过如下方式下载zcbus最新安装包。

八、附录
相较于openGauss 6.0.0之前版本，6.0.0的安装更简单便捷，节省了数据库学习成本。
另外通过zcbus数据同步软件，可实现oracle到openGauss的数据全量和增量同步，另外还可以实现MySQL等数据库产品到openGuass的同步。
在同步过程中，确实感触到openGauss 6.0.0对于Oracle数据库的支持的增强，兼容性很好。
zcbus也是一款优秀的数据同步工具，另外zcbus也有很多其它功能，比如可实现多点数据同步，数据的清洗，是一款非常优秀的数据交换平台。后期也会对zcbus有更多详细的介绍
