export MY_HOSTIP=192.168.116.147             ## IP地址

export MY_SOFTWARE_DIRECTORY=/opt/software/openGauss  ## 软件包所在目录

export MY_XML=/opt/software/openGauss/clusterconfig.xml   ##集群配置XML文件

export OPENGAUSS_DOWNLOAD_URL= https://opengauss.obs.cn-south-1.myhuaweicloud.com/5.0.1/x86_openEuler_2203/openGauss-5.0.0-openEuler-64bit.tar.bz2 ##openGauss安装压缩包下载地址

[root@openEuler2203 ~]# source /etc/profile.d/custom.sh

[root@openEuler2203 ~]# hostnamectl set-hostname $MY_HOSTNAME

[root@openEuler2203 ~]# vim /etc/hosts

在文末添加

192.168.116.147  openEuler2203   #openGauss OM IP Hosts Mapping

后保存退出

[root@openEuler2203 ~]# cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 locahost4.localdomain4

::1         localhost localhost.localdomain localhost6 locahost6.localdomain6

192.168.116.147  openEuler2203   #openGauss OM IP Hosts Mapping

2.Disable firewalld service

[root@openEuler2203 ~]# systemctl disable firewalld.service #使防火墙服务失效

Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.

Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@openEuler2203 ~]# systemctl stop firewalld.service #停止防火墙服务

[root@openEuler2203 ~]# systemctl status firewalld.service #查看防火墙状态

○ firewalld.service - firewalld - dynamic firewall daemon

     Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor prese>

     Active: inactive (dead)

       Docs: man:firewalld(1)

lines 1-10/10 (END)

[1]+  Stopped                 systemctl status firewalld.service

3.Disable SELINUX

[root@openEuler2203 ~]# echo "SELINUX=disabled" >> /etc/selinux/config

[root@openEuler2203 ~]# cat /etc/selinux/config | grep "SELINUX=disabled"

SELINUX=disabled

[root@openEuler2203 ~]# reboot #重启系统

4.Configure encoding

[root@openEuler2203 ~]# echo "LANG=en_US.UTF-8" >> /etc/profile

或者

[root@openEuler2203 ~]# vim /etc/profile

在文档末尾输入

LANG=en_US.UTF-8

[root@openEuler2203 ~]# source /etc/profile

5.Configure Timezone

2024-03-27 19:52:30.992513+08:00

6.Close swap partition

[root@openEuler2203 ~]# swapoff -a

7.在各数据库节点上，关闭RemoveIPC

（1）修改/etc/systemd/logind.conf文件中的“RemoveIPC”值为“no”。

[root@openEuler2203 ~]# vim  /etc/systemd/logind.conf

RemoveIPC=no

#RuntimeDirectorySize=10%

#RuntimeDirectoryInodesMax=

RemoveIPC=no

#InhibitorsMax=8192

#SessionsMax=8192

（2）修改/usr/lib/systemd/system/systemd-logind.service文件中的“RemoveIPC”值为“no”

[root@openEuler2203 ~]# echo "RemoveIPC=no" >>

 /usr/lib/systemd/system/systemd-logind.service

（3）重新加载配置参数

[root@openEuler2203 ~]# systemctl daemon-reload

[root@openEuler2203 ~]# systemctl restart systemd-logind

（4）检查修改是否生效

[root@openEuler2203 ~]# loginctl show-session | grep RemoveIPC

RemoveIPC=no

[root@openEuler2203 ~]# systemctl show systemd-logind | grep RemoveIPC

RemoveIPC=no

8.Configure SSH Service

[root@openEuler2203 ~]# echo "Banner none " >> /etc/ssh/sshd_config

[root@openEuler2203 ~]# echo "PermitRootLogin yes" >> /etc/ssh/sshd_config

或者

[root@openEuler2203 ~]# vim /etc/ssh/sshd_config

设置或输入

Banner none

PermitRootLogin yes

[root@openEuler2203 ~]# cat /etc/ssh/sshd_config

Banner none

PermitRootLogin yes

1. 关闭HISTORY记录

[root@openEuler2203 ~]# echo "HISTSIZE=0 " >> /etc/profile

1. 检查Python version

[root@openEuler2203 ~]# python3 --version

或者

[root@openEuler2203 ~]# python3 -V

Python 3.9.9

11.Configure sysctl.conf and performanc.sh

[root@openEuler2203 ~]# sysctl -w kernel.sem="250 85000 250 330"

kernel.sem = 250 85000 250 330

12.openGauss software download

[root@openEuler2203 ~]# cd $MY_SOFTWARE_DIRECTORY

[root@openEuler2203 openGauss]# wget $OPENGAUSS_DOWNLOAD_URL
