统信UOS系统安装OpenGauss5.0.0步骤

统信1060e安装OpenGauss5.0.0步骤

##使用yum来安装依赖包或者使用uos-server-20-1060e.iso镜像挂载安装（小编采用镜像挂载安装有关依赖）
yum -y install libaio-devel flex bison ncurses-devel glibc-devel patch redhat-lsb-core readline-devel python3

ifconfig enp18s0 mtu 8192
systemctl disable firewalld
systemctl stop firewalld

###关闭RemoveIPC
[root@klgdj ~]# sed -i ‘/^RemoveIPC/d’ /etc/systemd/logind.conf
[root@klgdj ~]# sed -i ‘/^RemoveIPC/d’ /usr/lib/systemd/system/systemd-logind.service
[root@klgdj ~]# echo “RemoveIPC=no” >> /etc/systemd/logind.conf
[root@klgdj ~]# echo “RemoveIPC=no” >> /usr/lib/systemd/system/systemd-logind.service

#vi /etc/sysctl.conf

###配置资源限制
echo “* soft stack 3072” >> /etc/security/limits.conf
echo “* hard stack 3072” >> /etc/security/limits.conf
echo “* soft nofile 1000000” >> /etc/security/limits.conf
echo “* hard nofile 1000000” >> /etc/security/limits.conf
echo “* soft nproc unlimited” >> /etc/security/limits.d/90-nproc.conf

###查看配置
tail -n 4 /etc/security/limits.conf
tail -n 1 /etc/security/limits.d/90-nproc.conf

关闭透明大页
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo ‘echo never > /sys/kernel/mm/transparent_hugepage/defrag’ >> /etc/rc.d/rc.local
echo ‘echo never > /sys/kernel/mm/transparent_hugepage/enabled’ >> /etc/rc.d/rc.local

[root@klgdj ~]# chmod +x /etc/rc.d/rc.local
[root@klgdj ~]# /usr/bin/sh /etc/rc.d/rc.local

设置字符集参数
###将数据库节点的字符集设置为en_US.UTF-8
echo “LANG=en_US.UTF-8” >> /etc/profile
source /etc/profile
echo $LANG

设置时区和时间
###查询时区
[root@klgdj ~]# timedatectl
timedatectl list-timezones |grep Shanghai
timedatectl set-timezone Asia/Shanghai

###使用swapoff -a命令将交换内存关闭—集群模式则需要各节点执行
###关闭命令
[root@klgdj ~]# swapoff -a
###开启命令
[root@klgdj ~]# swapon -a

###创建安装目录
mkdir -p /opt/software/openGauss
chmod 755 -R /opt/software

tar -zxvf openGauss-5.0.0-openEuler-64bit-all.tar.gz -C /opt/software/openGauss/
cd /opt/software/openGauss/
tar -zxvf openGauss-5.0.0-openEuler-64bit-om.tar.gz

###在/opt/software/openGauss 路径下，创建一个名为 cluster_config.xml的文件
cd /opt/software/openGauss
vim cluster_config.xml
###单节点配置文件

cd /opt/software/openGauss/script
./gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/cluster_config.xml --unused-third-party
报错一如下：
Exception: [GAUSS-51900] : The current OS is not supported.Supported platforms are: [‘suse’, ‘redhat’, ‘centos’, ‘euleros’, ‘openeuler’, ‘kylin’, ‘fusionos’, ‘asianux’, ‘debian’, ‘ubuntu’].
解决：

rm /etc/UnionTech-release
还原的话就是
rm -rf /etc/system-release
ln -s /etc/system-release /etc/UnionTech-release
rm /etc/openEuler-release
重启服务器
reboot
