Opengauss 在 Centos 7.8 下一主两备的安装测试
一、环境准备
原来有两台 vbox 虚拟机，装有 centos 7.8,不想重装操作系统，就克隆一台，这样有三台虚拟机用来测
试 opengauss 一主两备环境。
cat/etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.11 node1 #Gauss OM IP Hosts Mapping
192.168.56.12 node2 #Gauss OM IP Hosts Mapping
192.168.56.13 node3 #Gauss OM IP Hosts Mapping
cat /etc/centos-release
CentOS Linux release 7.8.2003 (Core)
uanme -a
Linux node2 3.10.0-1127.13.1.el7.x86_64 #1 SMP Tue Jun 23 15:46:38 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
修改版本号骗过 opengauss 检查
cat /etc/centos-release
CentOS Linux release 7.6.2003 (Core)
