一键部署openGauss2.1.0

#!/bin/bash## Author：贾军锋## Date：2021-10-25## OS:       CentOS7.6 x86_64 [小硬件配置：2c/4G]## Database：openGauss 2.1.0## Description：一键式实现操作系统环境配置、openGauss软件下载、openGauss软件安装等步骤，帮助大家提升安装openGauss数据库效率## Tips:     请确保操作系统符合要求并且可以连接外网

## 0.关闭virbr0网卡 [本地虚拟机标准化安装openEuler系统会默认存在virbr0网卡，删除该网卡以避免干扰数据库的安装]## virsh net-destroy default## virsh net-list## echo "Net device virbr0 is disabled."

## 1.定义主机信息[请根据实际情况修改]export MY_HOSTNAME=node1           ## 主机名export MY_HOSTIP=192.168.0.99      ## IP地址export MY_SOFTWARE_DIRECTORY=/soft/openGauss      ## 软件包所在目录export MY_XML=/soft/openGauss/clusterconfig.xml   ## 集群配置文件XMLexport openGauss_Download_url=https://opengauss.obs.cn-south-1.myhuaweicloud.com/2.1.0/x86/openGauss-2.1.0-CentOS-64bit-all.tar.gz  ## openGauss软件包下载地址
