MogDB/openGauss 手动部署(非OM工具)单机,主备,主备级联架构

使用场景

在某些安装程序尚未支持的操作系统上,安装程序(比如OM)会报操作系统不支持的错误,此时可以通过手动方式安装MogDB。

获取安装包

访问MogDB下载页面下载对应平台的安装包。解压标准安装包后得到的MogDB-x.x.x-openEuler-64bit.tar.gz即为手动安装所需的内核包。

前期准备

  1. 关闭防火墙,selinux

    systemctl disable firewalld.service
    systemctl stop firewalld.service
    setenforce=0
    sed -i '/^SELINUX=/c'SELINUX=disabled /etc/selinux/config
  2. 安装依赖包

    yum install libaio-devel -y
  3. 创建相关目录,用户,组

    groupadd dbgrp -g 2000
    useradd omm -g 2000 -u 2000
    echo "Enmo@123" | passwd --stdin omm
    mkdir -p /opt/mogdb/software
    mkdir -p /opt/mogdb/data
    chown -R omm:dbgrp /opt/mogdb
  4. 上传并解压二进制文件

    [root@mogdb-kernel-0001 software]# pwd
    /opt/mogdb/software
    [root@mogdb-kernel-0001 software]# ls -lrt
    total 90236
    -r-------- 1 root root 92401412 Jun 13 06:14 MogDB-3.0.1-openEuler-64bit.tar.gz
    chown omm:dbgrp MogDB-3.0.1-openEuler-64bit.tar.gz
    su - omm
    cd /opt/mogdb/software/
    tar -xf MogDB-3.0.1-openEuler-64bit.tar.gz

初始化数据库(单机)

  1. 配置环境变量

    echo "export GAUSSHOME=/opt/mogdb/software"  >> /home/omm/.bashrc && \
    echo "export PATH=\$GAUSSHOME/bin:\$PATH " >> /home/omm/.bashrc && \
    echo "export LD_LIBRARY_PATH=\$GAUSSHOME/lib:\$LD_LIBRARY_PATH" >> /home/omm/.bashrc
    source /home/omm/.bashrc
  2. init数据库

    bin/gs_initdb --pgdata=/opt/mogdb/data --nodename=primary --pwpasswd=Enmo@123 --encoding=UTF-8 --locale=en_US.UTF-8
  3. 修改初始化参数

    echo "port=26000" >> /opt/mogdb/data/postgresql.conf
    echo "listen_addresses = '0.0.0.0'" >> /opt/mogdb/data/postgresql.conf
    echo "password_encryption_type = 0" >> /opt/mogdb/data/postgresql.conf
    echo "log_directory = 'pg_log'" >> /opt/mogdb/data/postgresql.conf
    echo "remote_read_mode=non_authentication" >> /opt/mogdb/data/postgresql.conf
    echo "host all all 0.0.0.0/0 md5" >> /opt/mogdb/data/pg_hba.conf
  4. 启动数据库

    gs_ctl start -D /opt/mogdb/data

至此单机安装完成

主备安装

  1. 主库操作

    • 配置连接通道
    echo "replconninfo1='localhost=172.16.0.106 localport=26001 localheartbeatport=26005 localservice=26004 remotehost=172.16.0.245 remoteport=26001 remoteheartbeatport=26005 remoteservice=26004'
    " >> /opt/mogdb/data/postgresql.conf

    localhost为主库IP,remotehost为备库IP

    • 将主库以primary方式启动
    gs_ctl restart -D /opt/mogdb/data/ -M primary
  2. 备库操作

  • 前期准备工作如上(一)

  • 配置环境变量

    echo "export GAUSSHOME=/opt/mogdb/software"  >> /home/omm/.bashrc && \
    echo "export PATH=\$GAUSSHOME/bin:\$PATH " >> /home/omm/.bashrc && \
    echo "export LD_LIBRARY_PATH=\$GAUSSHOME/lib:\$LD_LIBRARY_PATH" >> /home/omm/.bashrc
    source /home/omm/.bashrc
    - 将主库的配置文件传到备库
    scp /opt/mogdb/data/pg_hba.conf /opt/mogdb/data/postgresql.conf 172.16.0.245:/opt/mogdb/data/
  • 配置连接通道,将localhost和remotehost对调.

    sed -i “/^replconninfo1/creplconninfo1=‘localhost=172.16.0.245 localport=26001 localheartbeatport=26005 localservice=26004 remotehost=172.16.0.106 remoteport=26001 remoteheartbeatport=26005 remoteservice=26004’” /opt/mogdb/data/postgresql.conf

    localhost为备库IP,remotehost为主库IP

  • 构建主备关系

    gs_ctl build -D /opt/mogdb/data/ -b full -M standby
  • 查询主备状态

    • 主库

      gs_ctl query -D /opt/mogdb/data/

至此主备已安装完成

主备级联安装

  1. 主备安装如上(一,二,三)

  2. 添加复制通道

    • 主库操作
    gsql -d postgres -p26000 -c “alter system set replconninfo2 to ‘localhost=172.16.0.106 localport=26001 localheartbeatport=26005 localservice=26004 remotehost=172.16.0.127 remoteport=26001 remoteheartbeatport=26005 remoteservice=26004 iscascade=true’;
    • 备库操作
    gsql -d postgres -p26000 -c “alter system set replconninfo2 to ‘localhost=172.16.0.245 localport=26001 localheartbeatport=26005 localservice=26004 remotehost=172.16.0.127 remoteport=26001 remoteheartbeatport=26005 remoteservice=26004 iscascade=true’;
  3. 级联库操作

  • 前期准备工作如上(一)

  • 配置环境变量

    echo "export GAUSSHOME=/opt/mogdb/software"  >> /home/omm/.bashrc && \
    echo "export PATH=\$GAUSSHOME/bin:\$PATH " >> /home/omm/.bashrc && \
    echo "export LD_LIBRARY_PATH=\$GAUSSHOME/lib:\$LD_LIBRARY_PATH" >> /home/omm/.bashrc
    source /home/omm/.bashrc
  • 将备库的配置文件传到级联库

    scp /opt/mogdb/data/pg_hba.conf /opt/mogdb/data/postgresql.conf 172.16.0.127:/opt/mogdb/data/
  • 配置连接通道

    sed -i "/^replconninfo1/creplconninfo1='localhost=172.16.0.127 localport=26001 localheartbeatport=26005 localservice=26004 remotehost=172.16.0.106 remoteport=26001 remoteheartbeatport=26005 remoteservice=26004'" /opt/mogdb/data/postgresql.conf
    sed -i "/replconninfo2/creplconninfo2='localhost=172.16.0.127 localport=26001 localheartbeatport=26005 localservice=26004 remotehost=172.16.0.245 remoteport=26001 remoteheartbeatport=26005 remoteservice=26004'" /opt/mogdb/data/postgresql.conf

    localhost为级联IP,remotehost为主库IP和备库IP。

  • 构建主备关系

    gs_ctl build -D /opt/mogdb/data/ -b full -M cascade_standby
