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,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。

  • 修改根目录下/etc/profile文件
  
  
  
[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

安装验证

查看数据库启动状态

通过openGauss提供的gs_om工具可以完成数据库状态检查
以omm用户身份登录服务器
检查数据库状态是否正常

  
  
  
[omm@node0 ~]$ gs_om -t status --detail

登录数据库

数据库安装完成后,默认生成名称为postgres的数据库。第一次连接数据库时可以连接到此数据库。

  
  
  
[omm@node0 ~]$ gsql -d postgres -p 15400
