openEuler搭建openGauss主从集群
一、系统环境
| 主机名 | IP | 系统 | 虚拟机内存 | 防火墙、selinux |
|---|---|---|---|---|
| Euler2（主） | 10.10.10.2 | openEuler release 20.03 (LTS) | 4G | off |
| Euler3（从） | 10.10.10.3 | openEuler release 20.03 (LTS) | 4G | off |
二、环境准备
官网地址：https://opengauss.org/zh/docs/1.0.1/docs/installation/%E8%8E%B7%E5%8F%96%E5%AE%89%E8%A3%85%E5%8C%85.html
1、下载依赖包（两个节点）
[root@Euler2 ~]# yum install -y libaio-devel flex bison ncurses-devel glibc-devel patch readline-devel
2、关闭swap（两个节点）
[root@Euler2 ~]# swapoff -a
3、关闭RemoveIPC（两个节点）
[root@Euler2 ~]# grep "RemoveIPC" /etc/systemd/logind.conf
RemoveIPC=no
[root@Euler2 ~]# systemctl restart systemd-logind
[root@Euler2 ~]# loginctl show-session | grep RemoveIPC
RemoveIPC=no
4、注释掉Banner（两个节点）
[root@Euler3 ~]# grep "#Banner" /etc/ssh/sshd_config
#Banner none
#Banner /etc/issue.net
[root@Euler2 ~]# systemctl restart sshd
5、创建用户（两个节点）
[root@Euler2 ~]# groupadd dbgrp
[root@Euler2 ~]# useradd omm -g dbgrp
[root@Euler2 ~]# id omm
uid=1000(omm) gid=1000(dbgrp) groups=1000(dbgrp)
[root@Euler2 ~]# echo 'omm'|passwd --stdin omm
6、解压包（Euler2）
[root@Euler2 ~]# mkdir -p /opt/software/openGauss
[root@Euler2 ~]# cd /opt/software/openGauss/
[root@Euler2 openGauss]# ls
openGauss-1.0.1-openEuler-64bit.tar.gz
[root@Euler2 openGauss]# chmod 755 -R /opt/software
[root@Euler2 openGauss]# tar xf openGauss-1.0.1-openEuler-64bit.tar.gz
7、修改performance.sh（两个节点）
[root@Euler2 openGauss]# vim /etc/profile.d/performance.sh ###注释掉
#sysctl -w vm.min_free_kbytes=112640 &> /dev/null
8、配置环境变量（Euler2 ）
[root@Euler2 openGauss]# vim /etc/profile
export LD_LIBRARY_PATH=/opt/software/openGauss/script/gspylib/clib:$LD_LIBRARY_PATH
[root@Euler2 openGauss]# . /etc/profile
二、安装openGauss
centos7中安装需要升级python3：./configure --with-ssl --enable-shared CFLAGS=-fPIC
1、创建XML文件（Euler2 ）
[root@Euler2 openGauss]# cat /opt/software/openGauss/cluster_config.xml
2、执行前置脚本（Euler2 ）
[root@Euler2 openGauss]# cd /opt/software/openGauss/script
[root@Euler2 script]# ./gs_preinstall -U omm -G dbgrp -X /opt/software/openGauss/cluster_config.xml

You can either reduce the request size or reconfigure the kernel with larger SHMALL. To reduce the request size (currently 4420542464 bytes), reduce PostgreSQL's shared memory usage, perhaps by reducing shared_buffers.
The PostgreSQL documentation contains more information about shared memory configuration.

7、修改postgresql.conf（两个节点）
[omm@Euler2 ~]$ vim /gauss/install/data/dn/postgresql.conf
max_process_memory = 3GB ###之前是2GB，运行不起来
shared_buffers = 256kB
8、启动集群
[omm@Euler2 ~]$ gs_om -t start
Starting cluster.
