一、RHAC集群的安装部署

(一)RHAC集群的介绍和环境检查

1.RHAC和HAC集群的比较

        RHAC集群是gbase8s数据库双机同步的一种方式,其和HAC集群在安装部署上的步骤大部分是相同的(环境准备、软件安装、实例初始化、数据同步),而且其和HAC集群的同步方式也是一样的,只有在主机和备机加入集群的步骤存在着细微的差异,主要体现在参数上。

       除此之外,RHAC和HAC的差异主要表现为应用场景、数据同步的时效性和其节点数量:

  • 应用场景:
    • HAC:主要针对的同城灾备,距离相对较近,对网络的要求相对较高
    • RHAC:主要针对的异地灾备,距离相对较远,对网络要求较低
  • 同步时效性
    • HAC:其同步可以分为三个级别,完全同步、半同步(指日志发送到备机但是没有应用而向主机发送收到指令)、异步
    • RHAC:其同步级别只能为异步,可以指定间隔时间(间隔多长时间进行同步)
  • 节点数量:
    • HAC:节点数量为2
    • RHAC:节点数量可以高于2

2.操作系统的版本

  • 节点1
--节点1
[root@node01 ~]# uname -a
Linux node01 3.10.0-1160.71.1.el7.x86_64 #1 SMP Tue Jun 28 15:37:28 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
--节点2
[root@node02 ~]# uname -a
Linux node02 3.10.0-1160.71.1.el7.x86_64 #1 SMP Tue Jun 28 15:37:28 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

3.数据库的相关信息

RHAC集群安装之前,需要主机和备机已经安装了数据库软件,其中主机还要已经初始化成功实例,数据库的信息(包括准备安装的备机)如下:

服务器名称IP数据库版本实例名称端口数据库安装路径数据存放路径
node01192.168.6.63.5.1node39099/opt/GBASE/gbase/home/gbasedbt/node_dbs
node02192.168.6.73.5.1node49099/opt/GBASE/gbase/home/gbasedbt/node_dbs

4.数据库状态和信息查看

二、SSC共享内存集群的安装部署

(一)SSC集群

1.SSC集群本次部署说明

        SSC集群是共享存储集群,多个数据库实例公用一个存储,由于没有相应的环境,故本次部署测试是在一台虚拟机上部署用两个实例公用一个数据文件进行模拟进行。

2.SSC集群本次部署信息说明

本次共享集群部署是在一台服务器上进行,所以只有一个IP地址,也只需安装一个软件但是是有两个实例,具体部署信息如下:

ip实例名称端口安装路径数据文件路径
192.168.6.6ssc19088/home/gbasedbt/gbase/home/gbasedbt/gbase/ssc1_dbs
192.168.6.6ssc29099/home/gbasedbt/gbase/home/gbasedbt/gbase/ssc1_dbs

3.SSC集群安装部署步骤

  • 192.168.6.6安装软件
  • 192.168.6.6进行实例初始化
  • 192.168.6.6调整环境变量文件,并复制重命名
  • 192.168.6.6调整连接控制文件,并复制重命名
  • 192.168.6.6调整参数控制文件,并复制重命名
  • 192.168.6.6重启节点1的数据库,使更改的参数生效
  • 192.168.6.6指定ssc1为主节点
  • 192.168.6.6启动节点2

(二)集群的部署

1.说明

本次默认192.168.6.6上已经安装了数据库软件(测试版本为3.5.1),且已经初始化实例,状态如下:

--192.168.6.6上查看节点状态,实例ssc1已经启动

--进行复制重命名为实例ssc2的环境变量文件
[gbasedbt@node01 ~]$ cp /home/gbasedbt/profile.ssc1 /home/gbasedbt/profile.ssc2

--将实例ssc2的环境变量文件进行改动,改动三处,实例名称、连接控制文件名称和参数控制文件
[gbasedbt@node01 ~]$ cat profile.ssc2
export GBASEDBTSERVER=ssc2
export GBASEDBTDIR=/home/gbasedbt/gbase
export GBASEDBTSQLHOSTS=/home/gbasedbt/gbase/etc/sqlhosts.ssc2
export ONCONFIG=onconfig.ssc2
export PATH=/home/gbasedbt/gbase/bin:$PATH
export DB_LOCALE=zh_CN.utf8
export CLIENT_LOCALE=zh_CN.utf8
export GL_USEGLU=1
export GL_DATE="%Y-%m-%d"
export GL_DATETIME="%Y-%m-%d %H:%M:%S"

3.调整连接控制文件并复制给ssc2

--调整后的连接参数文件如下,主要为增加实例ssc2的连接信息,主要差异为实例名称和端口
[gbasedbt@node01 ~]$ cat /home/gbasedbt/gbase/etc/sqlhosts.ssc1
ssc1 onsoctcp 192.168.6.6 9088
ssc2 onsoctcp 192.168.6.6 9099

--复制连接控制文件并重命名
[gbasedbt@node01 ~]$ cp /home/gbasedbt/gbase/etc/sqlhosts.ssc1 /home/gbasedbt/gbase/etc/sqlhosts.ssc2

--实例ssc2的连接控制文件不用调整,内容如下
[gbasedbt@node01 ~]$ cat /home/gbasedbt/gbase/etc/sqlhosts.ssc2
ssc1 onsoctcp 192.168.6.6 9088
ssc2 onsoctcp 192.168.6.6 9099

4.调整参数控制文件并复制给实例ssc2

  • 实例ssc1的参数文件主要调整有三个
    • SDS_ENABLE:用于启动和禁止SD的辅助功能,当设置为1时,主机down机后会自动接管数据库服务,所以主机设置为0,第二个节点设置为1
    • SDS_TEMPDBS:用于指定SD服务器在启动时动态创建的临时数据库空间的信息,需要配置临时数据库空间的相关信息,如数据库空间名称、路径、页面大小、偏移量和大小等。需要注意的是,对于每个SDS_TEMPDBS配置参数值,页面大小(pagesize)值必须是相同的。
    • SDS_PAGING:用来配置共享存储每个节点的独有缓冲区路径,需要配置两个文件路径
--实例ssc1关于三个参数的相关设置如下
[gbasedbt@node01 ~]$ cat /home/gbasedbt/gbase/etc/onconfig.ssc1|grep ^SDS|grep -v SDS_TIMEOUT|grep -v SDS_LOGCHECK|grep -v SDS_ALTERNATE|grep -v SDS_FLOW_CONTROL
SDS_ENABLE      0
SDS_TEMPDBS             sdstmpdbs1,/home/gbasedbt/gbase/ssc1/sdstmpdbs01,2,0,102400
SDS_PAGING              /home/gbasedbt/gbase/ssc1/pagefile01,/home/gbasedbt/gbase/ssc1/pagefile02
  • 将实例ssc1的实力复制并改名
[gbasedbt@node01 ~]$ cp /home/gbasedbt/gbase/etc/onconfig.ssc1 /home/gbasedbt/gbase/etc/onconfig.ssc2
  • 将实例ssc2的onconfig文件进行改动,改动参数如下:
--改动内容为:实例名称、实例编号、日志文件名称和共享存储的几个参数
--内容太长,将改动的参数进行罗列出来,需要改动内容如下(确保SERVERNUM和实例ssc1不一致)
MSGPATH /home/gbasedbt/gbase/tmp/online_ssc2.log
DBSERVERNAME ssc2
SERVERNUM 155
SDS_ENABLE            1
SDS_TEMPDBS           sdstmpdbs1,/home/gbasedbt/gbase/ssc2/sdstmpdbs01,2,0,102400
SDS_PAGING        /home/gbasedbt/gbase/ssc2/pagefile01,/home/gbasedbt/gbase/ssc2/pagefile02

  • 将实例ssc1和ssc2的onconfig文件进行对比
[gbasedbt@node01 ~]$ diff /home/gbasedbt/gbase/etc/onconfig.ssc2 /home/gbasedbt/gbase/etc/onconfig.ssc1
126c126
< MSGPATH /home/gbasedbt/gbase/tmp/online_ssc2.log
---
> MSGPATH /home/gbasedbt/gbase/tmp/online_ssc1.log
205,206c205,206
< SERVERNUM 155
< DBSERVERNAME ssc2
---
> SERVERNUM 154
> DBSERVERNAME ssc1
1300c1300
< SDS_ENABLE            1
---
> SDS_ENABLE      0
1302,1303c1302,1303
< SDS_TEMPDBS           sdstmpdbs1,/home/gbasedbt/gbase/ssc2/sdstmpdbs01,2,0,102400
< SDS_PAGING            /home/gbasedbt/gbase/ssc2/pagefile01,/home/gbasedbt/gbase/ssc2/pagefile02
---
> SDS_TEMPDBS           sdstmpdbs1,/home/gbasedbt/gbase/ssc1/sdstmpdbs01,2,0,102400
> SDS_PAGING            /home/gbasedbt/gbase/ssc1/pagefile01,/home/gbasedbt/gbase/ssc1/pagefile02

5.针对上述的参数文件创建相关的文件夹和相关文件

--实例ssc1,SDS的上述三个参数需要一个文件夹和三个文件
[root@node01 gbase]# mkdir /home/gbasedbt/gbase/ssc1
[root@node01 gbase]# touch /home/gbasedbt/gbase/ssc1/sdstmpdbs01
[root@node01 gbase]# touch /home/gbasedbt/gbase/ssc1/pagefile01
[root@node01 gbase]# touch /home/gbasedbt/gbase/ssc1/pagefile02
[root@node01 gbase]# chown -R gbasedbt:gbasedbt /home/gbasedbt/gbase/ssc1
[root@node01 gbase]# chmod 755 /home/gbasedbt/gbase/ssc1
[root@node01 gbase]# chmod 660 /home/gbasedbt/gbase/ssc1/*
--实例ssc2
cp /home/gbasedbt/gbase/ssc1 /home/gbasedbt/gbase/ssc2

6.搭建SSC共享集群

  • 重启ssc1实例
source /home/gbasedbt/profile.ssc1
onmode -ky
oninit -vy
  • 将ssc1设为共享存储的所有者数据库
--生效实例ssc1环境变量,指定ssc1
source /home/gbasedbt/profile.ssc1
onmode -d set SDS primary ssc1
--生效实例ssc2环境变量,启动ssc2
source /home/gbasedbt/profile.ssc2
oninit -vy

7.查看集群状态

--生效ssc1环境变量,查看
[gbasedbt@node01 ~]$ source /home/gbasedbt/profile.ssc1
