GaussDB安装

环境准备

1、关闭防火墙

systemctl stop firewalld

2、关闭selinux

临时禁用：setenforce 0

永久关闭：

vi /etc/selinux/config
SELINUX=disabled

reboot

3、修改系统环境字符集

echo $LANG

export LANG=en_US.UTF-8

永久修改

vi /etc/profile

添加 export LANG=en_US.UTF-8

source /etc/profile

4、设置时区和时间

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

5、关闭交换区

swapoff -a

6、修改hosts

ip   hostname

安装过程

1、解压安装脚本

tar -xvf GaussDBInstaller_Vx.x.x.x.tar.gz

2、解压安装包到 安装脚本的pkgDir目录下

tar -xvf GaussDB_X86_Kylinv10_Centralized_2.23.01.220_20230609012225.tar.gz -C /root/GaussDBInstaller/GaussDBInstaller/pkgDir/

3、配置install_cluster.conf

vi /root/GaussDBInstaller/GaussDBInstaller/

4、复制安装模式json文件到 GaussDBInstaller 根目录下（本次为集中部署）,修改配置文件

cp jsonFileSample/3_nodes_centralized.json ./install_cluster.json

vi install_cluster.json
