2.1、软硬件环境要求 介绍openGauss的软硬件环境要求。建议部署openGauss的各服务器具有等价的软硬件配置。 表 1 硬件环境要求 介绍openGauss的软硬件环境要求。建议部署openGauss的各服务器具有等价的软硬件配置。 -表1 列出了openGauss服务器应具备的最低硬件要求。在实际产品中硬件配置的规划需考虑数据规模及所期望的数据库响应速度。请根据实际情况进行规划。
题目配置描述内存功能调试建议32GB以上。性能测试和商业部署时单实例部署建议128GB以上。复杂的查询对内存的需求量比较高在高并发场景下可能出现内存不足。此时建议使用大内存的机器或使用负载管理限制系统的并发。CPU功能调试最小1×8核2.0GHz。性能测试和商业部署时建议1×16核2.0GHz。CPU超线程和非超线程两种模式都支持。说明个人开发者最低配置2核4G推荐配置4核8G。目前openGauss仅支持ARM服务器和基于x86_64通用PC服务器的CPU。硬盘用于安装openGauss的硬盘需最少满足如下要求至少1GB用于安装openGauss的应用程序。每个主机需大约300MB用于元数据存储。预留70%以上的磁盘剩余空间用于数据存储。建议系统盘配置为RAID1数据盘配置为RAID5且规划4组RAID5数据盘用于安装openGauss。有关RAID的配置方法在本手册中不做介绍。请参考硬件厂家的手册或互联网上的方法进行配置其中Disk Cache Policy一项需要设置为Disabled否则机器异常掉电后有数据丢失的风险。openGauss支持使用SSD盘作为数据库的主存储设备支持SAS接口和NVME协议的SSD盘以RAID的方式部署使用。网络要求300兆以上以太网。建议网卡设置为双网卡冗余bond。有关网卡冗余bond的配置方法在本手册中不做介绍。请参考硬件厂商的手册或互联网上的方法进行配置。 表 2 软件环境要求 软件类型配置描述Linux操作系统ARMopenEuler 20.03LTS推荐采用此操作系统openEuler 22.03LTS 麒麟V10 Asianux 7.5 x86openEuler 20.03LTS openEuler 22.03LTS entOS 7.6 Asianux 7.6 。说明1、当前安装包只能在英文操作系统上安装使用2、OM工具已经支持对基于openEuler/Centos等商业操作系统的安装使用具体配置信息可以查看OM中的osid.conf文件。Linux文件系统剩余inode个数 15亿推荐工具bzip2Python支持Python3.6 表 3 软件依赖要求 所需软件建议版本libaio-devel建议版本0.3.109-13readline-devel建议版本7.0-13libnslopenEulerx86环境中建议版本2.28-36 openGauss的软件依赖要求如表3 所示。 建议使用上述操作系统安装光盘或者源中下列依赖软件的默认安装包若不存在下列软件可参看软件对应的建议版本。 2.2、环境规划
类型名称主机名称Node1主机IP192.168.1.101操作系统版本CentOS 7.9openGauss版本openGauss_6.0.0-RC1 极简版部署方式单机模式
2.3、检查环境 操作系统版本
[rootNode1 ~]#[rootNode1 ~]# cat /etc/redhat-releaseCentOS Linux release 7.9.2009 (Core)[rootNode1 ~]# CPU核数 [rootNode1 ~]# cat /proc/cpuinfo | grep physical id | uniq | wc -l [rootNode1 ~]# 内存大小 [rootNode1 ~]# free -h total used free shared buff/cache availableMem: 7.6G 1.8G 3.6G 304M 2.3G 5.3GSwap: 4.0G 0B 4.0G[rootNode1 ~]#
2.4、安装依赖
yum install bzip2 libaio-devel readline-devel wget
2.5、检查Python版本
[rootNode1 ~]# python --versionPython 2.7.5[rootNode1 ~]#[rootNode1 ~]# python3 --version-bash: python3: command not found[rootNode1 ~]# 说明本例未安装Python3需安装Python3. 代码如下 yum install python3
2.6、关闭SELINUX
[rootNode1 ~]# sed -i s/SELINUXenforcing/SELINUXdisabled/ /etc/selinux/config[rootNode1 ~]#
2.7、关闭RemoveIPC 说明在各数据库节点上关闭RemoveIPC。CentOS操作系统默认为关闭可以跳过该步骤。 [rootNode1 ~]# [rootNode1 ~]# cat/etc/systemd/logind.confEOF RemoveIPCno EOF [rootNode1 ~]# [rootNode1 ~]# [rootNode1 ~]# cat/usr/lib/systemd/system/systemd-logind.serviceEOF RemoveIPCno EOF [rootNode1 ~]#
2.8、修改内核 sysctl -w kernel.sem250 85000 250 330
2.9、关闭防火墙
[rootNode1 ~]#[rootNode1 ~]# systemctl disable firewalld.serviceviceRemoved symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.[rootNode1 ~]# systemctl stop firewalld.service[rootNode1 ~]#systemctl disable firewalld
2. 10、检查服务器主机时间 [rootNode1 ~]# date Tue Aug 20 14:57:50 CST 2024 [rootNode1 ~]# 说明如果当前时间与本地时间不一致需修改。 2.11、关闭HISTORY记录 [rootNode1 ~]# sed -i “s/HISTSIZE1000/HISTSIZE0/” /etc/profile [rootNode1 ~]#
2.12、修改字符集
查看本地字符集
[rootNode1 ~]# localeLANGen_US.UTF-8LC_CTYPEen_US.UTF-8LC_NUMERICen_US.UTF-8LC_TIMEen_US.UTF-8LC_COLLATEen_US.UTF-8LC_MONETARYen_US.UTF-8LC_MESSAGESen_US.UTF-8LC_PAPERen_US.UTF-8LC_NAMEen_US.UTF-8LC_ADDRESSen_US.UTF-8LC_TELEPHONEen_US.UTF-8LC_MEASUREMENTen_US.UTF-8LC_IDENTIFICATIONen_US.UTF-8LC_ALL 修改字符集
[rootNode1 ~]#[rootNode1 ~]# cat /etc/profileEOF export LANGen_US.UTF08 EOF[rootNode1 ~]# 查看字符集
[rootNode1 ~]#[rootNode1 ~]# cat /etc/profile# /etc/profileunset iunset -f pathmungeexport LANGen_US.UTF-8[rootNode1 ~]#
2.13、以上设置完毕重启主机。
三、openGauss部署流程
3.1、新建管理用户
groupadd gauss -g 4000useradd gauss -g 4000 -u 4000echo gauss|passwd --stdin gauss
3.2、创建安装目录 目录规划
名称用途openGauss数据库安装的主目录install安装包上传目录 代码如下 mkdir /openGauss /installchmod 755 -R /openGauss /installchown -R gauss:gauss /openGauss /install
3.3、配置sudo使用root账户
sed -i.bak 100agauss ALL(ALL) NOPASSWD:ALL /etc/sudoers
3.4、安装包下载 官网地址https://opengauss.org/zh/download/ 说明 1、根据操作系统下载对应安装包 2、下载方式在线下载离线下载 3、切换gauss用户 4、本案例下载极简版部署。 代码如下

vi $GAUSSHOME/data/single_node/postgresql.conflisten_addresses *password_encryption_type 1vi $GAUSSHOME/data/single_node/pg_hba.confhost all all 0.0.0.0/0 sha256 4、以上配置信息修改完成后即可使用Navicat工具登录openGauss数据库。 四、部署问题
4.1、缺少依赖 报错截图如下 原因未安装bzip2依赖包。 安装bzip2依赖包方案如下图 4.2、修改内核参数 报错截图如下 原因未修改内核参数。 未修改内核参数方案如下图 4.3、bash: gs_ctl: command not found 说明在安装openGauss的时候脚本会在.bashrc文件中自动添加 ulimit -n 1000000 在注释掉该配置后切换用户就正常了。 错误代码如下
[gaussNode1 simpleInstall]$[gaussNode1 simpleInstall]$ gs_ctl restart -D $GAUSSHOME/data/single_node -Z single_nodebash: gs_ctl: command not found[gaussNode1 simpleInstall]$[gaussNode1 simpleInstall]$ 修改如下
vi /home/gauss/.bashrc 使修改生效 source /home/gauss/.bashrc
