解决方案
编辑配置文件，注释掉existCoordinateHost和existDataHost即可。
[gbase@rh6-1 gcinstall]$ cat demo.options
installPrefix= /opt
coordinateHost =10.0.2.201
coordinateHostNodeID = 234,235,237
dataHost = 10.0.2.201,10.0.2.202
#existCoordinateHost =10.0.2.201
#existDataHost =10.0.2.201,10.0.2.202
loginUser= root
loginUserPwd = '111111'
#loginUserPwdFile = loginUserPwd.json
dbaUser = gbase
dbaGroup = gbase
dbaPwd = 'gbase1234'
rootPwd = '111111'
#rootPwdFile = rootPwd.json
dbRootPwd = ''
#mcastAddr = 226.94.1.39
mcastPort = 5493
