GBase 8a多实例9.5.3版本扩容实例操作手顺

本文测试,在GBase 8a 9.5.3多实例版本,增加IP后扩容实例操作受训,不是扩容节点。

环境

单节点,3 IP,安装过程请参考 GBase 8a多实例版本9.5.3安装实例和运维常用命令

扩容方案

增加一个实例,IP为10.0.2.106

增加IP

在网卡配置文件里增加新的IP即可。

修改配置文件

在新增dataHost里,添加新的IP. 后面exists的各个参数,按照现有情况填写。

[gbase@gbase_rh7_003 gcinstall]$ cp demo.options  demo_2.options
[gbase@gbase_rh7_003 gcinstall]$ vi demo_2.options

existDataHost =10.0.2.103,10.0.2.104,10.0.2.105
existGcwareHost=10.0.2.103
gcwareHost =

#rootPwdFile = rootPwd.json
#characterSet = utf8
#dbPort = 5258
#sshPort = 22

扩容安装

这部分的操作,和安装是一样的。

[gbase@gbase_rh7_003 gcinstall]$ ./gcinstall.py --silent=demo_2.options
