南大通用数据库-Gbase-8a-学习-30-多VC安装（95版本）
一、环境
| 名称 | 值 |
|---|---|
| cpu | Intel® Core™ i5-1035G1 CPU @ 1.00GHz |
| 操作系统 | CentOS Linux release 7.9.2009 (Core) |
| 内存 | 3G |
| 逻辑核数 | 2 |
| 节点1-IP | 192.168.142.10 |
| 节点2-IP | 192.168.142.11 |
二、环境准备
1、关闭防火墙
所有部署节点执行此命令。
[root@czg0 pkg]# systemctl stop firewalld
[root@czg0 pkg]# systemctl disable firewalld
2、禁用selinux
所有部署节点进行修改。
将/etc/sysconfig/selinux中的SELINUX设置为disabled。
[root@czg0 pkg]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@czg0 pkg]# sestatus
SELinux status: disabled
3、创建gbase操作系统用户
所有部署节点执行此命令。
[root@czg0 pkg]# useradd gbase
[root@czg0 pkg]# passwd gbase
4、创建安装目录
所有部署节点执行此命令。
[root@czg0 pkg]# mkdir -p /opt/Gbase
[root@czg0 pkg]# chown -R gbase:gbase /opt/Gbase
三、集群部署
0、解压安装包
[root@localhost pkg]# tar -xvf GBase8a_MPP_Cluster-License-9.5.3.27-redhat7-x86_64.tar.bz2
1、SetSysEnv.py配置安装环境
每个节点都需要拷贝。
[root@czg0 gcinstall]# scp SetSysEnv.py 192.168.142.11:/opt/
Warning: Permanently added '192.168.142.11' (ECDSA) to the list of known hosts.
SetSysEnv.py 100% 29KB 1.3MB/s 00:00
每个节点都需要执行此脚本。
[root@czg1 opt]# python SetSysEnv.py --dbaUser=gbase --installPrefix=/opt/Gbase --cgroup
执行完最好看一下日志文件：/tmp/SetSysEnv.log
2、配置demo.options
[root@localhost pkg]# cd gcinstall/
[gbase@czg0 gcinstall]$ cat demo.options
installPrefix= /opt/Gbase
coordinateHost = 192.168.142.10,192.168.142.11
coordinateHostNodeID = 234,235,237
dataHost = 192.168.142.10,192.168.142.11
#existCoordinateHost =
#existDataHost =
#existGcwareHost=
gcwareHost = 192.168.142.10,192.168.142.11
#gcwareHostNodeID = 234,235,237
dbaUser = gbase
dbaGroup = gbase
dbaPwd = 'gbase'
rootPwd = 'qwer1234'
#dbRootPwd = ''
#rootPwdFile = rootPwd.json
#characterSet = utf8
#sshPort = 22
| 参数名 | 描述 |
|---|---|
| installPrefix | 指定安装目录。 |
| coordinateHost | 所有 coordinator 节点 IP 列表，IP 地址之间用“,”分隔。 |
| coordinateHostNodeID | 支持对 IPV6 地址的输入，当集群节点为 IPV4 地址，则该参数无效，可不用设置；当集群节点为 IPV6 地址，则用户必须手动设置该参数，该参数为若干个正整数，需要与 coordinateHost 中的 IP 一一对应，用逗号隔开。例如：coordinateHostNodeID = 1,2,3。 |
| dataHost | 所有数据节点 IP 列表，IP 地址之间用“,”分隔。 |
| existCoordinateHost | 所有已存在的 coordinator 节点 IP 列表，IP 地址之间用“,”分隔。 |
| existDataHost | 所有已存在的 data 节点 IP 列表，IP 地址之间用“,”分隔。 |
| gcwareHost | 所有gcware节点 IP 列表，IP 地址之间用“,”分隔。 |
| dbaUser | 操作系统中的数据库管理员用户，默认gbase。 |
| dbaGroup | 操作系统中的数据库管理员用户的用户组，默认gbase。 |
| dbaPwd | 操作系统中的数据库管理员用户的密码。 |
| rootPwd | 操作系统中的root用户密码。 |
| rootPwdFile | 该参数支持 root 用户在多节点不同密码方式，与参数rootPwd 不能同时使用，否则报错。默认密码 111111。 |
| dbRootPwd | 数据库 root 用户密码。安装集群时无需设置，仅在集群升级、扩容、节点替换时使用生效。 |
3、获取指纹信息
./getesn.py --silent=demo.options --passwordInputMod=pwdsame > License_2023_01_03.txt
写邮件加上附件License_2023_01_03.txt申请试用KEY。
9.5.3.27版本之后是getesn获取指纹信息，之前应该都是gethostsid。
4、安装软件
[root@localhost gcinstall]# ./gcinstall.py --silent=demo.options --license_file=你申请下来的试用KEY文件
显示如下表示成功
192.168.142.11 install gcware and cluster on host 192.168.142.11 successfully.
192.168.142.10 install gcware and cluster on host 192.168.142.10 successfully.

6、生成VC模板
[gbase@czg0 gcinstall]$ gcadmin createvc e vc.xml
[gbase@czg0 gcinstall]$ mv vc.xml vc1.xml
[gbase@czg0 gcinstall]$ cp vc1.xml vc2.xml
192.168.142.10设置为vc1。
192.168.142.11设置为vc2。
[gbase@czg0 gcinstall]$ cat vc1.xml
<?xml version='1.0' encoding="utf-8"?>
<servers>
<rack>

</servers>
7、创建VC
[gbase@czg0 gcinstall]$ gcadmin createvc vc1.xml
parse config file vc1.xml
generate vc id: vc00001
add vc information to cluster
add nodes to vc
gcadmin create vc [vc1] successful

9、设置分布式策略
（1）复制分片策略配置文件
[gbase@czg0 gcinstall]$ cp gcChangeInfo.xml gcChangeInfo_vc1.xml
[gbase@czg0 gcinstall]$ cp gcChangeInfo.xml gcChangeInfo_vc2.xml
（2）修改分片策略配置文件
[gbase@czg0 gcinstall]$ cat gcChangeInfo_vc1.xml
<?xml version="1.0" encoding="utf-8"?>
<servers>
<rack>
<node ip="192.168.142.10"/>
</rack>
</servers>
[gbase@czg0 gcinstall]$ cat gcChangeInfo_vc2.xml
<?xml version="1.0" encoding="utf-8"?>
<servers>
<rack>
<node ip="192.168.142.11"/>
</rack>
</servers>
（3）生成分布表
[gbase@czg0 gcinstall]$ gcadmin distribution gcChangeInfo_vc1.xml p 1 d 0 pattern 1 vc vc1 dba_os_password gbase
gcadmin generate distribution ...
[warning]: parameter [d num] is 0, the new distribution will has no segment backup
please ensure this is ok, input [Y,y] or [N,n]: y
NOTE: node [192.168.142.10] is coordinator node, it shall be data node too
gcadmin generate distribution successful
[gbase@czg0 gcinstall]$ gcadmin distribution gcChangeInfo_vc2.xml p 1 d 0 pattern 1 vc vc2 dba_os_password gbase
gcadmin generate distribution ...
[warning]: parameter [d num] is 0, the new distribution will has no segment backup
please ensure this is ok, input [Y,y] or [N,n]: y
NOTE: node [192.168.142.11] is coordinator node, it shall be data node too
check vc vc2 os password
copy system table to 192.168.142.11
gcadmin generate distribution successful
| 参数 | 描述 |
|---|---|
| p | 每一个节点的分片数。 |
| d | 副本数量。 |
| pattern number | 数据分布模式，pattern 1 为负载均衡模式，pattern 2 为高可用模式。默认模式1。 |
注意：
gcChangeInfo.xml 文件中 rack 内 node 数量需要大于参数 p 的值（每个节点存放主分片的数量）
10、检查集群分布策略
