安装前置操作
关闭防火墙
systemctl disable firewalld.servicesystemctl stop firewalld.service
关闭SELINUX
sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config
禁用swap
swapoff -avswapoff /dev/mapper/rhel-swap
设置主机互信
ssh-keygen -t rsassh-copy-id root@ip
操作系统参数设置

上传安装包和XML配置文件到/opt/software/openGauss目录
解压安装包
cd /opt/software/openGausstar -zxf openGauss-1.0.0-CentOS-64bit.tar.gz
设置lib库
export LD_LIBRARY_PATH=/opt/software/openGauss/script/gspylib/clib:$LD_LIBRARY_PATH
交互式HA环境检测及设置
确保两节点时间同步
cd /opt/software/openGauss/scriptpython3 gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig_ha.xml
初始化安装
su - ommgs_install -X /opt/software/openGauss/clusterconfig_ha.xml -l /tmp/gs_install.log
#安装过程中设置密码
