Posted 2021-04-06 字如其名

1查看系统版本
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core) 

2关闭防火墙，sellinux
systemctl disable firewalld.service && systemctl stop firewalld.service
[root@localhost ~]# vi /etc/selinux/config

[root@localhost ~]# setenforce 0
3修改hostname
[root@localhost ~]# hostnamectl set-hostname carl
[root@localhost ~]# cat /etc/hostname
carl
4关闭交换分区
[root@localhost ~]#swapoff -a

5添加163源
cat > /etc/yum.repos.d/163.repo <<EOF
[163]
name=163
baseurl=http://mirrors.163.com/centos/7/os/x86_64/
gpgcheck=0
enabled=1
EOF

6配置DNS
cat > /etc/resolv.conf <<EOF
nameserver 114.114.114.114
nameserver 1.2.4.8
EOF

7安装依赖包
yum -y  install wget  python3* bzip2 libaio-devel flex bison ncurses-devel

8创建文件夹，下载软件并解压
mkdir -p /opt/software/openGauss && chmod 755 -R /opt/software && cd /opt/software/openGauss
wget https://opengauss.obs.cn-south-1.myhuaweicloud.com/1.0.0/x86/openGauss-1.0.0-CentOS-64bit.tar.gz
tar -zxvf openGauss-1.0.0-CentOS-64bit.tar.gz

9添加临时环境变量
export LD_LIBRARY_PATH=/opt/software/openGauss/script/gspylib/clib:$LD_LIBRARY_PATH

10创建配置文件
cat > clusterconfig.xml <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<ROOT>
    <!-- openGauss整体信息 -->
    <CLUSTER>
        <PARAM name="clusterName" value="dbCluster" />
        <PARAM name="nodeNames" value="carl" />
        <PARAM name="backIp1s" value="192.168.5.223"/>
        <PARAM name="gaussdbAppPath" value="/opt/huawei/install/app" />
        <PARAM name="gaussdbLogPath" value="/var/log/omm" />
        <PARAM name="tmpMppdbPath" value="/opt/huawei/tmp" />
        <PARAM name="gaussdbToolPath" value="/opt/huawei/install/om" />
        <PARAM name="corePath" value="/opt/huawei/corefile" />
        <PARAM name="clusterType" value="single-inst"/>
    </CLUSTER>
    <!-- 每台服务器上的节点部署信息 -->
    <DEVICELIST>
        <!-- node1上的节点部署信息 -->
        <DEVICE sn="1000001">
            <PARAM name="name" value="carl"/>
            <PARAM name="azName" value="AZ1"/>
            <PARAM name="azPriority" value="1"/>
            <!-- 如果服务器只有一个网卡可用，将backIP1和sshIP1配置成同一个IP -->
            <PARAM name="backIp1" value="192.168.5.223"/>
            <PARAM name="sshIp1" value="192.168.5.223"/>
            
        <!--dbnode-->
        <PARAM name="dataNum" value="1"/>
        <PARAM name="dataPortBase" value="26000"/>
        <PARAM name="dataNode1" value="/opt/huawei/install/data/db1"/>
        </DEVICE>
    </DEVICELIST>
</ROOT>

11preinstall
cd /opt/software/openGauss/script
./gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/clusterconfig.xml

12切换用户安装openGauss
su - omm
gs_install -X /opt/software/openGauss/clusterconfig.xml

13登录数据库

[omm@carl ~]$ gsql -d postgres -p 26000
gsql ((openGauss 1.0.0 build 0bd0ce80) compiled at 2020-06-30 18:19:27 commit 0 last mr  )
Non-SSL connection (SSL connection is recommended when requiring high-security)
Type "help" for help.

14首次登录需要更改用户密码

15创建用户表空间数据库

postgres=# create user carl identified by 'A@123456';       
CREATE ROLE

postgres=# create tablespace carl owner carl relative location 'tbs' maxsize '100m';
CREATE TABLESPACE
postgres=# create database carl with owner=carl tablespace=carl;
CREATE DATABASE
postgres=# grant all on database carl to carl;
GRANT
postgres-# 

16使用carl登录数据库

备注：虚拟机安装内存是个神坑。
