openGauss描述

openGauss-5.0.2 迁移说明:
openGauss-5.0.2-loongarch64-all.tar.gz包含了官网 https://opengauss.org/zh/download/
openGauss Server 部分的 openGauss_5.0.2 企业版的全部内容
openGauss-5.0.2-loongarch64-connectors.tar.gz包含了官网 https://opengauss.org/zh/download/
openGauss Connectors部分的全部 4 个驱动程序的内容。
其中 bbox (程序崩溃时生成 coredump 的功能), llvm ( jit 功能) 2 个功能模块没有迁移，应该不影响正常使用。
缺少 128 原子指令，使用自旋锁软实现。

部署

单机版安装

参考文档：https://docs-opengauss.osinfra.cn/zh/docs/5.0.0/docs/InstallationGuide/%E5%8D%95%E8%8A%82%E7%82%B9%E5%AE%89%E8%A3%85.html

安装步骤

tar -zxvf openGauss-5.0.2-loongarch64-all.tar.gz
cd openGauss-5.0.2-loongarch64-all

tar -jxf openGauss-5.0.2-loongnix-64bit.tar.bz2 -C /mnt/openGauss
cd /mnt/openGauss/simpleInstall
sh install.sh -w "数据库密码" &&source ~/.bashrc

数据库操作

-- 连接数据库
gsql -d postgres -p 5432
-- 停止数据库
gs_ctl stop -D $GAUSSHOME/data/single_node -Z single_node
-- 启动数据库
gs_ctl start -D $GAUSSHOME/data/single_node -Z single_node

远程访问设置

停止数据库
修改 postgresql.conf 里面的 listen_addresses

vim $GAUSSHOME/data/single_node postgresql.conf
listen_addresses = '*'

启动数据库

集群方式安装

参考文档：https://docs-opengauss.osinfra.cn/zh/docs/5.0.0/docs/InstallationGuide/%E4%BC%81%E4%B8%9A%E7%89%88%E5%AE%89%E8%A3%85.html

安装步骤

mkdir -p /mnt/openGauss
chmod 755 -R /mnt/openGauss

tar -zxvf openGauss-5.0.2-loongarch64-all.tar.gz -C /mnt/openGauss
cd /mnt/openGauss/script/openGauss-5.0.2-loongarch64-all

tar -zxvf openGauss-5.0.2-loongnix-64bit-om.tar.gz

cd script
cp gspylib/etc/conf/cluster_config_template.xml ./cluster_config.xml

根据实际情况修改 cluster_config.xml 中机器的 ip 和 数据库安装目录
集群需要 ssh 互信，提前安装 expect

yum install expect

./gs_preinstall -U omm -G dbgrp -X /mnt/openGauss/openGauss-5.0.2-loongarch64-all/script/cluster_config.xml

su - omm
gs_install -X /mnt/openGauss/openGauss-5.0.2-loongarch64-all/script/cluster_config.xml


# 查看集群信息
gs_om -t status --detail

# 连接数据库
gsql -d postgres -p 15400

注意:
openGauss 安装的时候在 /etc/profile 里面修改了系统的 LD_LIBRARY_PATH，或者是 ~/.bashrc 里面修改了LD_LIBRARY_PATH ，由于 openGauss 自带了 openssl.so , libcrypto.so 等动态库，可能会导致系统执行 sudo， su ， yum 等命令的时候报错。
重置 LD_LIBRARY_PATH 后再次执行。
export LD_LIBRARY_PATH=

远程访问设置

与单机版安装中设置一样。

设置开机服务

设置gs_ctl工具的软连接

ln -s /mnt/openGauss/bin/gs_ctl /usr/local/bin

创建/etc/systemd/system/openGauss.service文件并添加服务配置

[Unit]
Description=華為openGauss數據庫服務...
After=network.target

[Service]
Type=forking
User=omm
Group=dbgrp

Environment="GAUSSHOME=/mnt/openGauss"
# 直接設置成LD_LIBRARY_PATH變量的值
Environment="LD_LIBRARY_PATH=/mnt/openGauss/lib"

ExecStart=/usr/local/bin/gs_ctl start -D /mnt/openGauss/data/single_node 
ExecReload=/usr/local/bin/gs_ctl restart -D /mnt/openGauss/data/single_node
ExecStop=/usr/local/bin/gs_ctl stop -D /mnt/openGauss/data/single_node
SuccessExitStatus=143
Restart=always

[Install]
WantedBy=multi-user.target

重新加载服务

sudo systemctl daemon-reload

重启服务

sudo systemctl start openGauss.service

查看服务状态
