案例說明：
KingbaseES V8R6部署一般可采用圖形化方式快速部署，但在生產一線，有的服務器系統未啟用圖形化環境，所以對於KingbaseES V8R6的集群需采用手工字符界面方式部署，本次文檔記錄了在一線環境下的字符界面部署操作步驟。
1）本案例在通用機環境下完成。
2）需要首先安裝KingbaseES R6 cluster版本的軟件包。
3）本案例主要用於系統環境不能提供圖形化部署或者圖形化部署中出現故障時。
4）本案例在通用機環境完成，專用機環境可用於參考。
5）通用機環境的操作基本由kingbase用戶完成。
6）在通過腳本一鍵部署R6集群時，請先做好系統環境的准備工作：（如ssh信任關系、防火牆、selinux配置、進程資源管理配置、用戶創建、ip分配等）。
一、 系統環境

二、 配置系統環境（all nodes）
2.1 創建kingbase用戶
[root@ECOLABAPP37 ~]# id kingbase
uid=1002(kingbase) gid=1002(kingbase) groups=1002(kingbase)
2.2 關閉主機系統防火牆
[root@ECOLABAPP37 Scripts]# systemctl stop firewalld
[root@ECOLABAPP37 Scripts]# systemctl disable firewalld
[root@ECOLABAPP38 ~]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
……
2.3 配置selinux
[kingbase@node3 ~]$ cat /etc/sysconfig/selinux |grep -v ^#|grep -v ^$
SELINUXTYPE=targeted
SELINUX=disabled
三、 通過腳本構建集群
3.1 配置部署環境
Kingbase用戶在宿主目錄下創建文件夾：
[kingbase@ECOLABAPP37 ~] mkdir R6_install
將部署腳本、配置文件及數據庫license.dat文件放置到當前目錄下。
[kingbase@ECOLABAPP37 ~]$ cd R6_install/
[kingbase@ECOLABAPP37 R6_install]$ ls -lh
total 80K
-rw------- 1 kingbase kingbase 5.0K Apr 19 17:28 install.conf
-rw-r--r-- 1 kingbase kingbase 2.9K Apr 19 17:20 license.dat
-r-xr-xr-x 1 kingbase kingbase 2.1K Apr 19 16:57 trust_cluster.sh
-rw------- 1 kingbase kingbase 32K Apr 19 16:57 V8R6_cluster_install.sh
-rw------- 1 kingbase kingbase 31K Apr 19 16:57 V8R6一鍵部署集群腳本操作手冊.docx
1) 查看和編輯集群配置文件（根據系統環境進行修改）
[kingbase@node3 ~]$ cat install.conf |grep -v ^#|grep -v ^$
on_bmj=0
all_ip=(10.248.52.165 10.248.52.166)
install_dir="/home/kingbase/cluster"
zip_package="/opt/Kingbase/ES/V8/DeployTools/zip/Aarch64/db.zip"
license_file=(license.dat)
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="oracle" # database mode: pg, oracle
db_auth="scram-sha-256" # database authority: scram-sha-256, md5, default is scram-sha-256
trusted_servers="10.248.48.1"
virtual_ip="10.248.52.174/20"
net_device=(nm-bond nm-bond)
ipaddr_path="/sbin"
arping_path="/usr/sbin"
ping_path="/bin"
super_user="root"
execute_user="kingbase"
reconnect_attempts="6" # the number of retries in the event of an error
reconnect_interval="10" # retry interval
recovery="manual" # the way of cluster recovery: automatic/manual
ssh_port="22" # the port of ssh, default is 22
2) 配置主機間ssh互信（可以手工配置，也可以通過以下腳本配置，建議手工配置）
注意：
需要配置kingbase用戶之間、root用戶之間、kingbase和root用戶之間，配置完成后檢查用戶信任關系
查看腳本內容（部分內容）：
[kingbase@ECOLABAPP37 R6_install]$ cat trust_cluster.sh
#!/bin/bash
# you should change two parameters: general_user and all_ip
# general_user is the general user which you want to config SSH password free
# all_ip is the devices that you want to config SSH password free
shell_folder=$(dirname $(readlink -f "$0"))
install_conf="${shell_folder}/install.conf"
primary_host=""
curren_user=`whoami`
......
for ips in ${all_ip[@]}
do
ssh -p ${ssh_port} root@$ips "cp -r /root/.ssh /home/$general_user/"
ssh -p ${ssh_port} root@$ips "chmod 700 /home/$general_user/.ssh/"
ssh -p ${ssh_port} root@$ips "chown -R $general_user:$general_user /home/$general_user/.ssh/"
done
3）查看cluser部署腳本（部分內容）
[kingbase@ECOLABAPP37 R6_install]$ cat V8R6_cluster_install.sh
#!/bin/bash
shell_folder=$(dirname $(readlink -f "$0"))
install_conf=""
#all_ip=(192.168.28.10 192.168.28.11)
all_ip=()
#install_dir="/home/kingbase/tmp_kingbase"
install_dir=""
#zip_package="${shell_folder}/db.zip"
zip_package=""
#license_path="${shell_folder}"
license_path="${shell_folder}"
#BMJ Kingbase install path
soft_dir="/opt/Kingbase/ES/V8/Server"
......
# start up the cluster
echo "[INSTALL] start up the whole cluster ..."
execute_command ${execute_user} ${all_ip[-2]} "${sys_bindir}/sys_monitor.sh start"
[ $? -ne 0 ] && exit 1
echo "[INSTALL] start up the whole cluster ... OK"
}
main
exit 0
3.2 執行腳本部署
注意：
必須將license.dat文件也存放到當前目錄下，缺少license.dat將會出現錯誤。
當前集群手工部署文件存儲目錄：
[kingbase@ECOLABAPP37 ~]$ cd R6_install/
[kingbase@ECOLABAPP37 R6_install]$ ls -lh
total 80K
-rw------- 1 kingbase kingbase 5.0K Apr 19 17:28 install.conf
-rw-r--r-- 1 kingbase kingbase 2.9K Apr 19 17:20 license.dat
-r-xr-xr-x 1 kingbase kingbase 2.1K Apr 19 16:57 trust_cluster.sh
-rw------- 1 kingbase kingbase 32K Apr 19 16:57 V8R6_cluster_install.sh
-rw------- 1 kingbase kingbase 31K Apr 19 16:57 V8R6一鍵部署集群腳本操作手冊.docx
執行部署腳本：
根據輸出日志信息，判斷部署過程中的故障。完整閱讀輸出日志，結合圖形化部署工具，可以加深repmgr集群部署的工作機制。

4.4 測試主備流復制同步
主庫DML操作：
test=# create database prod;
CREATE DATABASE
test=# \c prod;
You are now connected to database "prod" as user "system".
prod=# create table t1 (id int);
CREATE TABLE
prod=# insert into t1 values (10),(20),(30);
INSERT 0 3
prod=# select * from t1;

五、部署故障案例
故障現象說明：
沒有將license.dat文件存放到集群部署腳本的當前目錄下，在執行部署腳本時，出現故障，無法訪問到license.dat文件，后將license.dat文件拷貝到此目錄后，部署成功。

Examine the log output.
=注意：必須將license.dat文件也存放到當前目錄下，以上錯誤就是缺少license.dat=
在排除故障時，可以手工執行一下命令，然后查看故障日志：
