组件安装及管理

快速入门文章中我们介绍了 OpenTenBase 的架构、源码编译安装、集群运行状态、启动停止等内容。

应用接入中我们介绍了应用程序连接 OpenTenBase 数据库进行建库、建表、数据导入、查询等操作。

基本使用中我们介绍 OpenTenBase 中特有的shard表、冷热分区表、复制表的创建,和基本的DML操作。

高级使用中我们介绍 OpenTenBase 的高级使用操作内容,其中包含了各种窗口函数、Json/Jsonb、游标、事务、锁等的使用。

在本篇文章中我们将深入到 OpenTenBase 各种组件内部,对各种组件的初始化、参数配置、启停、运行状态查看、路由生效配置等进行单独的详细介绍。

机器准备

  • 服务器数量

创建OS用户

  • 创建操作系统运行用户
[root@VM_0_29_centos ~]# adduser -d /data/opentenbase opentenbase
  • 配置操作系统用户密码
[root@VM_0_29_centos pgxztmp]# passwd opentenbase
  • 创建opentenbase应用程序运行目录
[root@VM_0_29_centos pgxz]# su opentenbase  
[opentenbase@VM_0_29_centos install]$ mkdir -p /data/opentenbase/install/pgxz
  • 创建opentenbase数据目录
[root@VM_0_29_centos pgxz]# su opentenbase  
[opentenbase@VM_0_29_centos install]$ mkdir -p /data/opentenbase/data/pgxz
  • 上传pgxz应用程序到目录/data/opentenbase/install/pgxz下面,目录的结构为
[opentenbase@VM_0_29_centos pgxz]$ ll /data/opentenbase/install/pgxz
total 4
drwxrwxr-x 2 pgxz pgxz 4096 Nov 10 04:33 bin

drwxrwxr-x 4 pgxz pgxz  172 Nov 10 04:33 lib
drwxrwxr-x 3 pgxz pgxz   24 Oct  1 14:54 share
[opentenbase@VM_0_29_centos pgxz]$ 
  • 配置pgxz用户的环境变量
[opentenbase@VM_0_29_centos ~]$ vim /data/opentenbase/.bashrc 
# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

export OPENTENBASE_HOME=/data/opentenbase/install/pgxz
export PATH=$OPENTENBASE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$OPENTENBASE_HOME/lib:${LD_LIBRARY_PATH}

GROUP(存储组)配置

创建默认GROUP

创建默认GROUP

[opentenbase@VM_0_29_centos ~]# psql -h 172.16.0.29 -p 15432 -d postgres -U opentenbase
psql (PostgreSQL 10.0 opentenbase V2)
Type "help" for help.

postgres=#
create default node group default_group with(dn01, dn02);
create sharding group to group default_group;
clean sharding;

至此,OpenTenBase 就可以像单机数据库一样使用了。

查询已经创建的GROUP

[opentenbase@VM_0_29_centos ~]# psql -h 172.16.0.29 -p 15432 -d postgres -U opentenbase
