三、升级步骤
cexec命令的安装步骤看之前的写的文章里有，文章连接：南大通用数据库-Gbase-8a-学习-12-Gbase8a常用运维命令（持续更新哈）
1、确定业务是否停止
确保没有运行的Sql。
[gbase@localhost gcinstall]$ cexecs data: 'gncli -uroot -e "show processlist"|grep -v Sleep'
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
Id User Host db Command Time State Info
36 root localhost NULL Query 0 NULL show processlist
2、定时任务检查
（1）查看定时任务
[root@localhost opt]# cexecs data: 'cat /var/spool/cron/gbase'
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
0 */2 * * * /opt/gnode/server/bin/gc_syncpacklog.sh /opt
（2）注释定时任务
如果升级时间段内有定时任务需注释。
[root@localhost opt]# cexecs data: 'sed -i "s/^[^#]/#&/" /var/spool/cron/gbase'
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
[root@localhost opt]# cexecs data: 'cat /var/spool/cron/gbase'
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
#0 */2 * * * /opt/gnode/server/bin/gc_syncpacklog.sh /opt
（3）解除定时任务注释（升级结束后执行）
[root@localhost opt]# cexecs data: 'sed -i "s/^[#]//" /var/spool/cron/gbase'
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
[root@localhost opt]# cexecs data: 'cat /var/spool/cron/gbase'
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
0 */2 * * * /opt/gnode/server/bin/gc_syncpacklog.sh /opt
3、检查集群状态
如果有节点异常，先处理再升级。
[root@localhost opt]# gcadmin
CLUSTER STATE: ACTIVE
CLUSTER MODE: NORMAL
=====================================================================
| GBASE COORDINATOR CLUSTER INFORMATION |
=====================================================================
| NodeName | IpAddress |gcware |gcluster |DataState |
---------------------------------------------------------------------
| coordinator1 | 192.168.142.12 | OPEN | OPEN | 0 |
---------------------------------------------------------------------
=================================================================
| GBASE DATA CLUSTER INFORMATION |
=================================================================
|NodeName | IpAddress |gnode |syncserver |DataState |
-----------------------------------------------------------------
| node1 | 192.168.142.12 | OPEN | OPEN | 0 |
-----------------------------------------------------------------
4、检查EVENT
（1）查看命令
[root@localhost opt]# gcadmin showdmlevent
Event count:0
[root@localhost opt]# gcadmin showddlevent
Event count:0
[root@localhost opt]# gcadmin showdmlstorageevent
Event count:0
（2）日志排查
如果上述结果有不为0的，需查看日志中是否有报错日志，根据报错解决相应问题。
[gbase@localhost gcinstall]$ tail -f /opt/gcluster/log/gcluster/gc_recover.log
2022-08-23 09:39:09.242 [INFO ] <RECOVER-INFO>: Recover Thread(0x7fccba42c700) is been built success

2022-08-23 09:39:09.243 [INFO ] <GCWare>: master node is: 210675904 192.168.142.12
5、集群版本检查（升级前后都需要做）
升级前后都需要记录，分别升级后做版本对比。
（1）集群服务版本
[gbase@localhost gcinstall]$ cexecs coor: "/opt/gcluster/server/bin/gclusterd -V"
************************ coor ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
/opt/gcluster/server/bin/gclusterd ver 8.6.2.43-R33.132743 for unknown-linux-gnu on x86_64
（2）数据节点服务版本
[gbase@localhost gcinstall]$ cexecs data: "/opt/gnode/server/bin/gbased -V"
************************ data ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
/opt/gnode/server/bin/gbased ver 8.6.2.43-R33.132743 for unknown-linux-gnu on x86_64
（3）gcadmin版本
[gbase@localhost gcinstall]$ cexecs "gcadmin -V"
************************ coor ************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.
gcadmin 1.2.9 build 129123
（4）其他组件版本
gbase> SHOW VARIABLES LIKE '%VERSION';
+----------------------------+---------------------+

| version | 8.6.2.43-R33.132743 |
+----------------------------+---------------------+
5 rows in set (Elapsed: 00:00:00.01)
6、停止集群服务
[root@localhost opt]# cexec all: "service gcware stop"
************************* all *************************
--------- 192.168.142.12---------
Warning: Permanently added '192.168.142.12' (ECDSA) to the list of known hosts.

7、获取现有SCN和TABLEID
记录现有的SCN号和TABLEID号，用于升级意外失败的手工恢复。
[gbase@localhost gcinstall]$ python
Python 2.7.5 (default, Jun 28 2022, 15:30:04)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gcware
>>> gcware.getscn()
16
>>> gcware.gettableid()
8
8、集群配置文件备份
（1）集群层配置文件备份
[root@czg2 ~]# cexec coor: 'cp -a /opt/gcluster/ /home/gbase/bak/'
（2）数据层配置文件备份
[root@czg2 ~]# cexec coor: 'cp -a /opt/gnode/ /home/gbase/bak/'
（3）其他配置文件备份
[root@czg2 ~]# cexec coor: "cp -a /var/lib/gcware/ /home/gbase/bak/ "
[root@czg2 ~]# cexec coor: "cp -a /etc/corosync /home/gbase/bak/ "
9、解压新版本
[root@localhost opt]# cd /opt/pkg/Gbase8a-34/
[root@localhost Gbase8a-34]# ll
总用量 88300
-rw-rw-rw- 1 root root 90416620 8月 23 09:20 GBase8a_MPP_Cluster-NoLicense-8.6.2_build43-R34-2-redhat7-x86_64.tar.bz2
[root@localhost Gbase8a-34]# tar -xvf GBase8a_MPP_Cluster-NoLicense-8.6.2_build43-R34-2-redhat7-x86_64.tar.bz2
10、修改配置文件
[root@localhost gcinstall]# cat demo.options
installPrefix= /opt
coordinateHost = 192.168.142.12
coordinateHostNodeID = 234,235,237
dataHost = 192.168.142.12
#existCoordinateHost =
#existDataHost =
loginUser= root
loginUserPwd = 'qwer1234'
#loginUserPwdFile = loginUserPwd.json
dbaUser = gbase
dbaGroup = gbase
dbaPwd = 'gbase'
rootPwd = 'qwer1234'
#rootPwdFile = rootPwd.json
dbRootPwd = ''
#mcastAddr = 226.94.1.39
mcastPort = 5493
11、集群升级
（1）升级命令
[gbase@czg2 gcinstall]$ python gcinstall.py --silent=demo.options -U
192.168.142.12 Install gcluster on host 192.168.142.12 successfully.

12、修改参数
V8.6.2build43R31及之后的版本推荐添加或修改如下参数。
所有管理节点都需要添加这两个参数，后续需重启数据库。
（1）corosync.conf参数
| 参数名 | 描述 |
|---|---|
| inner_connect_read_write_timeout | gbase_inner_connect 连接、写、读的超时时间。 |
| 参数值：整数型 1~5，单位：秒，默认值：1，最大值 5。 |
添加到gcware标签里。

}
}
（2）gcluster_shrink_to_rebalance
| 参数名 | 描述 |
|---|---|
| gcluster_shrink_to_rebalance | rebalance 实现 shrink space 功能和原 shrink space 功能共存，用参数控制：gcluster_shrink_to_rebalance |
| 默认值 0； 取值 1： 打开 shrink to rebalance 功能； 取值 0：关闭shrink to rebalance 功能。 |
在gbase_8a_gcluster.cnf中的模块[gbased]中添加gcluster_shrink_to_rebalance参数。

14、验证升级情况
重复：5、集群版本检查（升级前后都需要做）
[gbase@czg2 gcinstall]$ gccli
GBase client 8.6.2-R43.34.27468a27. Copyright (c) 2004-2022, GBase. All Rights Reserved.

15、升级失败回退
（1）方法一
先杀掉gbase用户下的残留进程。
[root@czg2 gcinstall]# ./Restore.py --help
Usage: Restore.py [options]
Options:
-h, --help show this help message and exit
-a do not prompt the user for confirmation
--backupFile=BACKUPFILE
backup file.
--silent=SILENTCONFIG
use the supplied properties file for a 'silent'
restore
--passwordInputMode=PASSWORDINPUTMODE
This process get password method, default:file. mode
["file","pwdsame","pwddiff"]
file: get from config file[password without
encrypted]. pwdsame: get
password from user input when all node password same.
pwddiff: get password from user input for nodes one by
one.
[gbase@localhost gcinstall]$ ./Restore.py --backupFile=/home/gbase/gcluster_backup_xxxx.tar.bz2 --silent=demo.options
gcluster_backup_xxxx.tar.bz2是执行升级脚本后，自动生成的backup 文件。最后出现Success to RestoreLocal的字样，表示回退成果。
（2）方法二
先停服务用新版本unInstall.py卸掉新版本，再用老版本gcinstall.py安装，需要和原来路径一致。再停服务，把 6、集群配置文件备份中的文件移动回原位置之前，最好把原位置的文件先删除，最后再启动服务即可。
