一、安装环境

服务器	安装目标
10.0.0.255	主
10.0.0.8	备

1.1 安装前准备

1. 创建部署用户（集群用户）kingbase
2. 创建安装目录

分别在各个节点执行如下命令

# 分别在各个节点执行如下命令
# 创建集群用户
useradd -U -m kingbase
# 创建安装目录
mkdir -p /data/kingbase/
cd /data/
# 归属
chown kingbase:kingbase kingbase

3. 创建安装文件存放目录,在主节点上执行（10.0.0.255）

mkdir -p /home/kingbase/r6_install/

4. 配置开放端口或者关闭防火墙

分别在各个集群节点上执行如下命令：

#数据库端口默认 54321，
firewall-cmd --zone=public --add-port=54321/tcp --permanent
# HA-LOG 分析工具默认端口 65432
firewall-cmd --zone=public --add-port=65432/tcp --permanent
# sys_securecmdd 工具默认端口 8890
firewall-cmd --zone=public --add-port=8890/tcp --permanent

二、开始安装

2.1 安装数据库

推荐在集群主机上安装数据库（10.0.0.255），具体安装过程请参考上一篇文章。

2.2 安装集群

2.2.1 获取集群安装文件

安装成功后，请在 ${install_dir}/ClientTools/guitools/DeployTools/zip/目录下获取如下文件：

• db.zip #数据库服务器压缩包
• cluster_install.sh # 部署脚本
• install.conf # 部署配置文件
• trust_cluster.sh # 配置 SSH 免密脚本

将如上文件复制到 /home/kingbase/r6_install/

cp db.zip cluster_install.sh install.conf trust_cluster.sh /home/kingbase/r6_install/

请单独准备 license.dat 授权文件并上传至/home/kingbase/r6_install/

2.2.2 配置 install.conf

编辑 install.conf 文件

cd /home/kingbase/r6_install/
vim install.conf

文件中配置项很多，大部分都有默认值，如无特殊需求不需要修改，下面是总结出来的必填项和主要的配置项

## 所有节点IP
all_ip=(10.0.0.225 10.0.0.8)
## 集群安装目录
install_dir="/data/kingbase/cluster"
## 安装文件目录
zip_package="/home/kingbase/r6_install/db.zip"

## 数据库用户名、密码
db_user="system"                 # the user name of database
db_password="123456"             # the password of database.
db_port="54321"                  # the port of database, defaults is 54321
db_mode="mysql"                 # database mode: pg, oracle, mysql
db_auth="scram-sha-256"          # database authority: scram-sha-256, md5, scram-sm3, sm4, default is scram-sha-256
# 大小写敏感
db_case_sensitive="no" 

# 网关
trusted_servers="10.0.0.1"
# 漂移IP
virtual_ip="10.0.0.220"
# 漂移IP 对应的物理IP网卡
net_device=(eth0 eth0)
#漂移IP 对应的物理IP
net_device_ip=(10.0.0.225 10.0.0.8)
use_scmd=0     

2.2.3 SSH 免密配置

使用 trust_cluster.sh 进行 SSH 免密配置，免密配置后，请验证即将要部署集群的所有设备的 root 用户和普通用户之间的免密是否配置正确。

# 使用root用户执行，脚本会根据install.conf 中配置的IP、和用户进行免密设置
./trust_cluster.sh

# 如看到  check ssh connection success! 	则代表配置成功

2.2.4 集群部署

集群部署用户执行 sh cluster_install.sh 命令进行集群部署，部署脚本将按照配置自动完成集群部署工作。

su - kingbase
# 执行脚本前请检查各个机器节点上的安装目录/data/kingbase/及归属是否为kingbase用户
sh cluster_install.sh  

看到类似如下的输出信息，则代表集群安装完成：
