VMware安装openEuler虚拟机

通过yum 安装openGauss数据库

前提: 确保OpenEuler网络连接正确(能ping通)
验证过程:

1. ping www.baidu.com
   • 失败情况: ping www.baidu.com:Name or service not known
   • 成功情况:64 bytes from ...........(下下图)

失败情况下的联网方法:

nmcli connection reload
nmcli connection up ens33

显示:Connection successfully ....如图

再次尝试ping:ping www.baidu.com

成功:

网络连接成功

更换openEular-20.03-LTS的yum源

1. 备份原有yum源

cd /etc/yum.repos.d/
mv openEuler.repo openEuler.repo.bak

2. 将openEular-20.03-LTS的yum源文件通过MobaXterm上传至 etc/yum.repos.d/文件夹下
   这里需要使用MobaXterm.
   具体配置操作见:MobaXterm连接虚拟机
   连接成功后,
   
   将文件直接拖拽到指定文件夹:/etc/yum.repos.d/

添加成功

注:一下命令使用MobaXterm或虚拟机里执行都可以
3. 更新yum源:

yum clean all
yum makecache 

4. 升级系统中所有有可用的升级的软件包:dnf update --allowerasing.--allowerasing参数用来替换冲突的软件包
   时间很长,耐心等待:(建议用MobaXterm,多次对比感觉会快些)

结束截图:

5. 使用reboot命令来重启系统

重启系统后还是ping不同的,需要重新连接(见文章开头),如果使用MobaXterm需要重新连接

安装openGauss

1. 使用yum install -y opengauss安装
   开始安装
   
   

2. 安装成功后使用su - opengauss命令切换到openGauss用户
   

3. 执行gs_ctl query指令查询数据库实例状态:

4. 执行gs_ctl stop指令停止数据库实例进程
   
   至此,安装和检验完成
