GBase 8a V95版本的domain方式安装,IP可以轻松更换了

GBase 8a在V95版本开始,支持用domain方式来安装集群,只要DNS解析配置好。更换IP时,修改DNS,然后重启数据库服务就可以了。

安装配置文件demo.options

注意如下几点:
1、管理节点的数量coordinateHost,必须和coordinateHostNodeID相同
2、coordinateHostNodeID 必须是数字,可以0开头。

[gbase@gbase_rh7_001 gcinstall]$ cat demo.options
installPrefix= /opt/gbase
coordinateHost = gbase_rh7_001,gbase_rh7_003
coordinateHostNodeID = 001,003
dataHost = gbase_rh7_001,gbase_rh7_003
#existCoordinateHost =10.0.2.101
#existDataHost =10.0.2.101
dbaUser = gbase
dbaGroup = gbase
dbaPwd = 'gbase1234'
rootPwd = ''
#rootPwdFile = rootPwd.json

DNS配置/etc/hosts

如下是hosts的配置样例,所有节点都要做。

[root@gbase_rh7_003 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.2.101  gbase_rh7_001
10.0.2.102  gbase_rh7_002
10.0.2.104  gbase_rh7_003

安装过程

注意其中现实的是domainName 而不是IP了。

初始化和校验

请注意,在gcware.conf里,其nodeid就是配置文件里的参数,这个是不允许修改的。

停掉服务[有可能不需要]

因为IP要换了,所以所有节点都要停下来。特别是gcware和gclusterd服务节点。
