金仓数据库KES物理备份操作

rman单机本地备份操作步骤

一、配置物理备份前提条件

1、创建备份目录

mkdir /home/kingbase/kbbr_repo

2、数据库开启归档

（1）修改配置文件kingbase.conf中参数：

archive_mode=on

archive_command=’’

（2）重启数据库

sys_ctl restart -D /home/kingbase/KingbaseES/V8/data

3、配置ssh免密登录

kingbase用户执行

ssh-keygen -t rsa

ssh-copy-id -i /home/kingbase/.ssh/id_rsa.pub kingbase@192.168.114.13

ssh-copy-id -i /home/kingbase/.ssh/id_rsa.pub root@192.168.114.13

二、配置物理备份

1、修改物理备份配置文件

vi /home/kingbase/KingbaseES/V8/Server/bin/sys_backup.conf

# target db style enum:  single/cluster

_target_db_style="single"

# one kingbase node IP

# just provide one IP, script will use 'repmgr cluster show' get other node IP

_one_db_ip="192.168.114.13" --本机物理IP

# local repo IP, inner-REPO, must be same as one_db_ip, means repo located in one db node

# outer repo IP, outer-REPO, means repo located in outer node

_repo_ip="192.168.114.13" --本机物理IP，与_one_db_ip配置相同

# label of this cluster

_stanza_name="kingbase"

# OS user name of database

_os_user_name="kingbase"

# !!!! dir to store the backup files

# should be accessable for the OS user

_repo_path="/home/kingbase/kbbr_repo" --备份路径

# count of keep, over the count FULL-backup will be remove

_repo_retention_full_count=5 --全量备份保留5份

# count of days, interval to do FULL-backup

_crond_full_days=7 --每周一次全量备份

# count of days, interval to do DIFF-backup

_crond_diff_days=0 --不进行差异备份

# count of days, interval to do INCR-backup

_crond_incr_days=1 --每天一次增量备份

# HOUR to do the FULL-backup

_crond_full_hour=2 --每天凌晨两点进行全量备份

# HOUR to do the DIFF-backup

_crond_diff_hour=3

# HOUR to do the INCR-backup

_crond_incr_hour=4 --每天凌晨四点进行增量备份

# OS cmd define

_os_ip_cmd="/usr/sbin/ip"

_os_rm_cmd="/bin/rm"

_os_sed_cmd="/bin/sed"

_os_grep_cmd="/bin/grep"

# !!! these follow 4 parameter ONLY for single style

# data dir of single

_single_data_dir="/home/kingbase/KingbaseES/V8/data"

# bin dir of single

_single_bin_dir="/home/kingbase/KingbaseES/V8/Server/bin"

#_single_bin_dir="/home/kingbase/KingbaseES/V8/Server/bin"

# database user of single

_single_db_user="system"

# database port of single

_single_db_port="54321"

2、执行sys_backup.sh init备份初始化

cd /home/kingbase/KingbaseES/V8/Server/bin/

./sys_backup.sh init

——执行后会在备份文件路径 /home/kingbase/kbbr_repo 创建文件夹、文件、配置文件等，并备份一次全量数据。

3、执行sys_backup.sh start添加定时任务

cd /home/kingbase/KingbaseES/V8/Server/bin/

./sys_backup.sh start

——执行后会在定时任务中添加备份任务

4、查看定时任务
