1、資料庫軟體安裝路徑

=此版本的軟體安裝路徑和前面的版本相比有了較大變化，通過軟連結可以在一個父目錄下建立多個版本的軟體=

[kingbase@node1 V8R6C5_41]$ ls -lh
total 0
lrwxrwxrwx 1 kingbase kingbase 68 Mar 21 15:04 ClientTools -> /opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/ClientTools/
lrwxrwxrwx 1 kingbase kingbase 60 Mar 21 15:04 doc -> /opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/doc/
lrwxrwxrwx 1 kingbase kingbase 64 Mar 21 15:04 install -> /opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/install/

2、配置歸檔

[root@node1 data]# cat kingbase.conf |grep -i archive_
archive_mode = on               # enables archiving; off, on, or always
archive_command='export TZ=Asia/Shanghai;/opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/Server/bin/sys_rman --config /home/kingbase/kbbr6_repo/sys_rman.conf --stanza=kingbase archive-push %p'
 

3、配置備份配置檔案

[kingbase@node1 bin]$ cat sys_backup.conf
#file: sys_backup.conf
#dest dir: <cluster_dir>/kingbase/bin/sys_backup.conf
#dest dir: <cluster_dir>/kingbase/share/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="127.0.0.1" 
# local repo IP, inner-REPO, means repo located in one db node
# outer repo IP, outer-REPO, means repo located in outer node
_repo_ip="127.0.0.1"
# 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/kbbr6_repo"
# count of keep, over the count FULL-backup will be remove
_repo_retention_full_count=5 
# count of days, interval to do FULL-backup
_crond_full_days=7  
# count of days, interval to do DIFF-backup
_crond_diff_days=0 
# count of days, interval to do INCR-backup
_crond_incr_days=1
# HOUR to do the FULL-backup
_crond_full_hour=2 
# HOUR to do the DIFF-backup
_crond_diff_hour=3 
# HOUR to do the INCR-backup
_crond_incr_hour=4 
# band witdh limit, fixed in Mb/s, default 0 means no limit
_band_width=0
# OS cmd define
_os_ip_cmd="/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="/data/kingbase/v8r6c5_041/data"
# bin dir of single
_single_bin_dir="/opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/Server/bin"
# database user of single
_single_db_user="system"
# database port of single
_single_db_port="54321"

# on means sys_securecmd, off means normal ssh
_use_scmd=on

4、執行備份的初始化

[kingbase@node1 bin]$ ./sys_backup.sh init
Please input password ...
# generate single sys_rman.conf...DONE
# update single archive_command with sys_rman.archive-push...DONE
# create stanza and check...(maybe 60+ seconds)
# create stanza and check...DONE
# initial first full backup...(maybe several minutes)
# initial first full backup...DONE
# Initial sys_rman OK.

5、檢視初始化後備份目錄及配置檔案

[kingbase@node1 bin]$ ls -lh /home/kingbase/kbbr6_repo/
total 4.0K
drwxr-x--- 3 kingbase kingbase  21 Mar 21 15:46 archive
drwxr-x--- 3 kingbase kingbase  21 Mar 21 15:46 backup
-rw-rw-r-- 1 kingbase kingbase 539 Mar 21 15:46 sys_rman.conf

#配置檔案
[kingbase@node1 bin]$ cat /home/kingbase/kbbr6_repo/sys_rman.conf 
# Genarate by script at 20220321154646, should not change manually
[kingbase]
kb1-path=/data/kingbase/v8r6c5_041/data
kb1-port=54321
kb1-user=system

[global]
repo1-path=/home/kingbase/kbbr6_repo
repo1-retention-full=5
log-path=/opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/Server/log
log-level-file=info
log-level-console=info
log-subprocess=y
process-max=4
#### default gz, support: gz none
compress-type=gz
compress-level=3
band-width=0
cmd-ssh=/opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/Server/bin/sys_securecmd

6、檢視備份日誌

[kingbase@node1 log]$ cat sys_rman_stanza-create.log

2022-03-21 15:46:47.031 P00   INFO: stanza-create command begin 2.27: --cmd-ssh=/opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/Server/bin/sys_securecmd --config=/home/kingbase/kbbr6_repo/sys_rman.conf --exec-id=28484-a4317ee9 --kb1-path=/data/kingbase/v8r6c5_041/data --kb1-port=54321 --kb1-user=system --log-level-console=info --log-level-file=info --log-path=/opt/Kingbase/ES/V8R6C5_41/KESRealPro/V008R006C005B0041/Server/log --log-subprocess --repo1-path=/home/kingbase/kbbr6_repo --stanza=kingbase
2022-03-21 15:46:48.196 P00   INFO: stanza-create for stanza 'kingbase' on repo1
2022-03-21 15:46:49.295 P00   INFO: stanza-create command end: completed successfully (2267ms)

7、備份故障案例分析

故障現象：

故障分析：
1）檢視sys_backup.conf配置

2）檢查資料庫歸檔配置

故障原因：

8、總結

1）最新版本的軟體安裝目錄儲存方式有較大的變化
2）執行ssh跨節點訪問，專門的命令：sys_securecmd 
3）在備份前，需要檢查下kingbase.conf中歸檔的配置
