virtualbox安装openGauss

一、安装环境

1）virtualbox
2）openEuler20.03 、openGauss5.0.0
3）关闭THP：

vim /etc/rc.d/rc.local

增加如下内容：

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi

4）修改权限

chmod +x /etc/rc.d/rc.local

5）关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

6）重启系统： reboot

7）上传clusterconfig.xml到虚拟机

8）修改clusterconfig.xml：将hostname和ip改成你自己虚拟机的主机名称和IP
9）执行install.sh：在执行过程中，需要输入4次密码

二、脚本附件

1. install_x86.sh

   #!/bin/bash
   
   # 设置字符集参数
   cat >>/etc/profile<<EOF
   export LANG=en_US.UTF-8
   EOF
   
   # 使修改生效
   source /etc/profile
   
   # 修改python版本并安装libaio包
   mv /usr/bin/python /usr/bin/python.bak
   ln -s /usr/bin/python3 /usr/bin/python
   python -V
   yum install libaio* -y
   
   # 创建目录，用于存放openGauss软件包
   mkdir -p /opt/software/openGauss
   mv clusterconfig.xml /opt/software/openGauss/
   cd /opt/software/openGauss
   
   # 下载openGauss安装包并解压
   wget https://opengauss.obs.cn-south-1.myhuaweicloud.com/5.0.0/x86_openEuler/openGauss-5.0.0-openEuler-64bit-all.tar.gz
   tar -zvxf openGauss-5.0.0-openEuler-64bit-all.tar.gz
   tar -zvxf openGauss-5.0.0-openEuler-64bit-om.tar.gz
   
   # 预安装数据库
   chmod -R 755 /opt/software/openGauss
   cd /opt/software/openGauss/script
   ./gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig.xml
   
   chown omm:dbgrp -R /opt/software/
   
   # 安装数据库，注意：以下操作是在suben用户下执行
   su - omm -c 'gs_install -X /opt/software/openGauss/clusterconfig.xml --gsinit-parameter="--encoding=UTF8"  --dn-guc="max_process_memory=4GB"  --dn-guc="shared_buffers=256MB" --dn-guc="bulk_write_ring_size=256MB" --dn-guc="cstore_buffers=16MB";gs_om -t status --detail'
   

2. clusterconfig.xml
