1、安装前准备
官网下载软件包
安装python3
yum install -y python3
安装相关依赖包
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
2、安装openGauss
创建安装目录
mkdir -p /home/software/openGauss
chmod -R 755 /home/software/
上传安装包到目录下并解压
[root@hades openGauss]# ll
