| 参数名 | 描述 |
|---|---|
| installPrefix | 指定安装目录. |
| coordinateHost | 所有 coordinator 节点 IP 列表,IP 地址之间用“,”分隔. |
| coordinateHostNodeID | 支持对 IPV6 地址的输入,When the cluster node is IPV4 地址,则该参数无效,可不用设置;When the cluster node is IPV6 地址,Then the user must set this parameter manually,This parameter is several positive integers,需要与 coordinateHost 中的 IP 一一对应,用逗号隔开.例如：coordinateHostNodeID = 1,2,3. |
| existCoordinateHost | 所有已存在的 coordinator 节点 IP 列表,IP 地址之间用“,”分隔. |
| existDataHost | 所有已存在的 data 节点 IP 列表,IP 地址之间用“,”分隔. |
| loginUser | by this user ssh to each node of the cluster,再 su 切换到 root 用户执行命令,该参数必须使用.默认用户为 root.The user group to which the user belongs must also be loginUser. |
| loginUserPwd | 表示用户 loginUser The same way as passwords on cluster nodes; |
| loginUserPwdFile | Indicates support for the user loginUser The way of different passwords on cluster nodes.Both cannot be used together,否则报错,You can select parameters to use according to the similarities and differences of passwords,必须使用其一.The default passwords are both 111111. |
| dbaUser | The database administrator user in the operating system,默认gbase. |
| dbaGroup | User group for the database administrator user in the operating system,默认gbase. |
| dbaPwd | The password of the database administrator user in the operating system. |
| rootPwd | 操作系统中的root用户密码. |
| rootPwdFile | 该参数支持 root Users have different passwords on multiple nodes,与参数rootPwd 不能同时使用,否则报错.默认密码 111111. |
| dbRootPwd | 数据库 root 用户密码.No setup is required when installing a cluster,Only on cluster upgrades、扩容、It takes effect when the node is replaced. |
| mcastAddr | 组播地址,缺省值为 226.94.1.39,Multicast mode will cause network storm,Therefore it is not recommended to use this method,如果将 mcastAddr 参数删除,则会按照 UDPU 方式进行安装,We recommend users to install in this way. |
| mcastPort | 组播端口,缺省值为 5493,如果按照 UDPU 方式安装,则此参数无效. |
3、安装软件
[[email protected] gcinstall]# ./gcinstall.py --silent=demo.options
显示如下表示成功
192.168.142.11 Installing gcluster.
192.168.142.10 Install gcluster on host 192.168.142.10 successfully.
192.168.142.11 Install gcluster on host 192.168.142.11 successfully.
192.168.142.10 Install gcluster on host 192.168.142.10 successfully.
Starting all gcluster nodes...
Adding new datanodes to gcware...
InstallCluster Successfully
4、查看集群状态
[[email protected] gcinstall]# gcadmin
CLUSTER STATE: ACTIVE
CLUSTER MODE: NORMAL
=====================================================================
| GBASE COORDINATOR CLUSTER INFORMATION |
=====================================================================

-----------------------------------------------------------------
5、Set up a distributed strategy
[[email protected] gcinstall]# su - gbase
上一次登录：日 8月 7 20:29:00 CST 2022pts/3 上
[[email protected] ~]$ cd /opt/pkg/gcinstall/
[[email protected] gcinstall]$ vim gcChangeInfo.xml
[[email protected] gcinstall]$ cat gcChangeInfo.xml
<?xml version="1.0" encoding="utf-8"?>
<servers>
<rack>
<node ip="192.168.142.10"/>
<node ip="192.168.142.11"/>
</rack>
</servers>
[[email protected] gcinstall]$ gcadmin distribution gcChangeInfo.xml p 1 d 0
gcadmin generate distribution ...
[warning]: parameter [d num] is 0, the new distribution will has no segment backup
please ensure this is ok, input y or n: y
NOTE: node [192.168.142.10] is coordinator node, it shall be data node too
NOTE: node [192.168.142.11] is coordinator node, it shall be data node too
gcadmin generate distribution successful
| 参数 | 描述 |
|---|---|
| p | The number of shards per node. |
| d | 副本数量. |
| pattern number | Data distribution pattern,pattern 1 为负载均衡模式,pattern 2 为高可用模式.默认模式1. |
注意：
gcChangeInfo.xml 文件中 rack 内 node The quantity needs to be greater than the parameter p 的值（每个
The node stores the number of primary shards）,否则会出现如下错误：
[[email protected] gcinstall]$ gcadmin distribution gcChangeInfo.xml p 2 d 0
gcadmin generate distribution ...
[warning]: parameter [d num] is 0, the new distribution will has no segment backup
please ensure this is ok, input y or n: y
rack[1] node number:[2] shall be greater than segment number each node:[2]
please modify file [gcChangeInfo.xml] and try again
gcadmin generate distribution failed
6、Check the cluster distribution strategy
[[email protected] gcinstall]$ gcadmin showdistribution
Distribution ID: 1 | State: new | Total segment num: 2
Primary Segment Node IP Segment ID Duplicate Segment node IP
========================================================================================================================
| 192.168.142.10 | 1 | |
------------------------------------------------------------------------------------------------------------------------
| 192.168.142.11 | 2 | |
========================================================================================================================
7、Initialize node data distribution
[[email protected] gcinstall]$ gccli
GBase client 8.6.2.43-R33.132743. Copyright (c) 2004-2022, GBase. All Rights Reserved.
gbase> initnodedatamap;
Query OK, 0 rows affected, 1 warning (Elapsed: 00:00:01.87)
gbase>
这里就安装完成了,After that, you can operate the database normally,命令类似于MySql.
8、错误记录
Error records of previous deployments,暂时未找到原因,Find out why later,Tell everyone about the solution,Guess it might be a lack of resources.

执行卸载脚本
[[email protected] gcinstall]# ./unInstall.py --silent=demo.options
Can not get gcluster node info:'NoneType' object has no attribute '__getitem__'
我们看一下源码unInstall.py,是在341和448Error thrown by one of the two,It looks like there is an error in judging whether the scheduling node and the data node have functions,这里先不做探讨,We'll look at it later when we have time.
try:
existCoordinateHost = GetExistCoordinateHost()
existDataHost = GetExistDataHost(prefix,dbaUser)
except Exception, err:
raise Exception("Can not get gcluster node info:%s" % str(err))
InstallFuns.py中包含GetExistCoordinateHost和GetExistDataHost的定义.
def GetExistCoordinateHost():
coordinateHost = []
coroConf = '/etc/corosync/corosync.conf'
if(not path.exists('/var/lib/gcware/SCN')):
return coordinateHost
[rv, out, err] = ExecCMD("cat %s | grep memberaddr" % coroConf)
if(not rv):
lines = out.split('\n')
for l in lines:
if(len(l.strip()) > 0):
ip = l.split("memberaddr:")[1].strip()
if(len(ip) > 0):
coordinateHost.append(ip)
else:
raise Exception(err)
coordinateHost = Distinct(coordinateHost)
return coordinateHost
def GetExistDataHost(prefix,dbaUser):
dataNodes = []
if IsFederalCluster(dbaUser, prefix) != "GBase8a_85":
dataServerFile = '/var/lib/gcware/DATASERVER'
dataServerFileBak = '/var/lib/gcware/DATASERVER.bak'
JA=None
JB=None
if os.path.exists(dataServerFile):
FA = file(dataServerFile)
JA = json.load(FA)
FA.close()
if os.path.exists(dataServerFileBak):
FB = file(dataServerFileBak)
JB = json.load(FB)
FB.close()
JSON = JA
if int(JB['epoch']) > int(JA['epoch']):
JSON = JB
nodes = JSON['nodes']
for node in nodes:
dataNodes.append(node['ipaddr'])
else:
dataServerFile = '/var/lib/gcware/CIB.xml'
logger.debug("Get exist data hosts from %s." % dataServerFile)
if not os.path.exists(dataServerFile):
return dataNodes
f = file(dataServerFile)
s = f.read()
f.close()
root = ElementTree.fromstring(s)
for el in root.find('nodes').findall('node'):
ip = el.get('ipaddr')
dataNodes.append(ip)
return IPConvToComp(dataNodes)
Because the above uninstall script reported an error,Let's clean it up manually,Every node has to do it.
rm -fr /opt/gcluster
rm -fr /opt/gnode
rm -fr /opt/gcware
userdel -r gbase
rm -fr /opt/gcluster
rm -fr /opt/gnode
rm -fr /etc/corosync/corosync.conf
rm -fr /var/lib/gcware
rm -fr /etc/init.d/gbased
rm -fr /etc/init.d/gcrecover
rm -fr /etc/init.d/gclusterd
