在第一講的分享中，我們揭開了華為GuassDB數(shù)據(jù)庫的神秘面紗，那么本期我們繼續(xù)分享第二講——GaussDB 100 OLTP 單機在RHEL7.6上的安裝。
你需要知道的
GaussDB 100 OLTP x86 版本請自行向官方申請，目前暫未對外公開（申請）
GaussDB 100 OLTP x86_64 基于 RedHat 7.6 安裝（Host IP：192.168.43.175）
DataStudio 基于 Windows 7 安裝（Host IP：192.168.43.147）
RHEL7.6 操作系統(tǒng)安裝
參考?RHEL 7.6 安裝
GaussDB 100安裝
01
環(huán)境設(shè)置
關(guān)閉Selinux
vim /etc/selinux/config
修改 SELINUX=enforcing 為 SELINUX=disabled
關(guān)閉防火墻
systemctl?stop?firewalld.service
systemctl?disable?firewalld.service
編輯環(huán)境變量
[root@henry ~]# vim /etc/profile
添加 ulimit -c unlimited
刷新環(huán)境變量
[root@henry ~]# source /etc/profile
編輯內(nèi)核參數(shù)
[root@henry ~]# vim /etc/sysctl.conf?
添加 kernel.core_pattern = /corefile/core-%e-%p-%t
刷新內(nèi)核參數(shù)
[root@henry ~]# sysctl -p
02

創(chuàng)建用戶組用戶
[root@henry ~]# groupadd dbgrp?
[root@henry ~]# useradd -g dbgrp -d /home/omm -m -s /bin/bash omm
修改用戶密碼
[root@henry ~]# passwd omm
Changing password for user omm.?
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:?
passwd: all authentication tokens updated successfully.
創(chuàng)建文件夾
[root@henry ~]# mkdir -p /opt/software/gaussdb

DataStudio 連接
01
服務(wù)器環(huán)境設(shè)置
添加白名單
[root@henry ~]# cd /opt/gaussdb/data/cfg/?
[root@henry cfg]# vim zhba.conf?
