关闭swap交换内存

关闭swap交换内存是为了保障数据库的访问性能，避免把数据库的缓冲区内存淘汰到磁盘上。如果服务器内存比较小，内存过载时，可打开swap交换内存保障正常运行。

[root@node0 ~]# swapoff -a

设置网卡MTU值

# 设置网卡MTU，MTU值推荐8192
[root@node0 ~]# ifconfig ens33 mtu 8192

# 查看网卡MTU
[root@node0 ~]# ifconfig -a |grep -i mtu
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 8192
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536

关闭RemoveIPC

修改logind.conf文件

# 使用vi打开logind.conf文件
[root@node0 ~]# vi  /etc/systemd/logind.conf

# 修改“RemoveIPC”值为“no”

修改systemd-logind.service文件

# 使用vi打开systemd-logind.service文件
[root@node0 ~]# vi /usr/lib/systemd/system/systemd-logind.service

# 修改“RemoveIPC”值为“no”
# 文件中没有配置参数，追加到文件的末尾即可

重新加载配置参数

[root@node0 ~]# systemctl daemon-reload
[root@node0 ~]# systemctl restart systemd-logind

检查修改是否生效

[root@node0 ~]# loginctl show-session | grep RemoveIPC
RemoveIPC=no
[root@node0 ~]# systemctl show systemd-logind | grep RemoveIPC
RemoveIPC=no

关闭HISTORY记录

为避免指令历史记录安全隐患，需关闭各主机的history指令。

[root@node0 ~]# vi /etc/profile

设置HISTSIZE值为0

系统中HISTSIZE默认值为1000，将其修改为0。
保存/etc/profile。 :wq

设置/etc/profile生效

[root@node0 ~]# source /etc/profile

设置root用户远程登录

在openGauss安装时需要root帐户远程登录访问权限
数据库需要root互信时才开启远程连接。在各主机操作完成并且验证完毕后请及时注销root用户，避免误操作。

修改PermitRootLogin配置，允许用户远程登录

打开sshd_config文件

[root@node0 ~]# vi /etc/ssh/sshd_config

修改权限配置

# 方式1：注释掉“PermitRootLogin no”
#PermitRootLogin no

# 方式2：将“PermitRootLogin”改为“yes”
PermitRootLogin=yes

执行 :wq 保存并退出编辑页面

修改Banner配置，去掉连接到系统时，系统提示的欢迎信息。欢迎信息会干扰安装时远程操作的返回结果，影响安装正常执行。

编辑sshd_config文件

vi /etc/ssh/sshd_config

修改Banner配置，注释掉“Banner”所在的行

执行 :wq 保存并退出编辑页面

使设置生效

[root@node0 ~]# systemctl restart sshd.service

以root用户身份重新登录

[root@node0 ~]# ssh 192.168.192.129

创建用户和用户组

为了实现安装过程中安装帐户权限最小化，及安装后openGauss的系统运行安全性，安装脚本在安装过程中会自动按照用户指定内容创建安装用户，并将此用户作为后续运行和维护openGauss的管理员帐户。

用户组：dbgrp

[root@node0 ~]# groupadd dbgrp

用户：omm

[root@node0 ~]# useradd -g dbgrp omm
[root@node0 ~]#
[root@node0 ~]# echo 'omm!666' | passwd --stdin omm
Changing password for user omm.
passwd: all authentication tokens updated successfully.
[root@node0 ~]#
[root@node0 ~]# id omm
uid=1001(omm) gid=1001(dbgrp) groups=1001(dbgrp)

创建目录

以root用户登录待安装openGauss的主机，并按规划创建存放安装包的目录。
不建议把安装包的存放目录规划到openGauss用户的根目录或其子目录下，可能导致权限问题。
openGauss用户须具有/opt/software/openGauss目录的读写权限。

[root@node0 ~]# mkdir -p /opt/software/openGauss
[root@node0 ~]# chmod 755 -R /opt/software

上传安装包

将安装包openGauss-5.0.0-openEuler-64bit-all.tar.gz上传至所创建的/opt/software/openGauss目录中

[root@node0 openGauss]# pwd

[root@node0 openGauss]# ll
