openEuler安装openGauss数据库教程【简洁版-适用于5.0.0-5.0.3】

修改主机名

hostnamectl set-hostname ogserver

配置主机名至 host 文件

echo "IP 地址 ogserver" >>/etc/hosts

关闭防火墙和 Selinux

systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce 0

关闭 transparent_hugepage

echo "transparent_hugepage=never" >> /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg

#IPC 参数设置

echo "RemoveIPC=no" >> /etc/systemd/logind.conf
echo "RemoveIPC=no" >> /usr/lib/systemd/system/systemd-logind.service

systemctl daemon-reload
systemctl stop systemd-logind
systemctl start systemd-logind

创建用户和目录

groupadd -g 1000 dbgrp
useradd -u 1000 omm -g dbgrp

设置 omm 用户密码（可自定义，注意记住该密码）

echo "Omm@1000" | passwd omm --stdin

创建数据库安装所需目录，并授权

mkdir -p /data/{
   
   openGauss,backup,archive_wals,core_pattern}
chmod 700 /data/{
   
   openGauss,backup,archive_wals,core_pattern}
chown -R omm:dbgrp /data/{
   
   openGauss,backup,archive_wals,core_pattern}
mkdir -p /opt/openGauss
chown omm:dbgrp -R /opt/openGauss/
chmod 755 /opt/openGauss/

core_pattern 设置

echo "/data/core_pattern/core-%e-%p-%t" > /proc/sys/kernel/core_pattern

安装依赖包

yum install -y zlib-devel libaio libuuid readline-devel krb5-libs
yum install
