1 错误现象

在部署 GBase 8c 分布式集群的时候报如下错误：

[dave@www.cndba.cn script]$ 
[dave@www.cndba.cn script]$ ./gha_ctl install -c gbase -p /home/gbase
{
    "ret":-1,
    "msg":"'NoneType' object has no attribute 'group'"
}
[dave@www.cndba.cn script]$

gbase 安装日志默认在/tmp/gha_ctl/gha_ctl.log,查看安装日志：http://www.cndba.cn/dave/article/131449

2 解决方法

这种错误的原因有 3 种：http://www.cndba.cn/dave/article/131449

1. etcd 的端口被占用了，这个可以通过netstat -an 确认。
2. 集群节点之间时间不同步。
3. yml 配置文件格式不正确。

我们这里的的原因就是yml 格式的问题。 开始我是手工修改的 IP地址，没有解决问题，后来重新配置，在 vim 中使用%s 命令替换 IP 地址后，问题解决。 http://www.cndba.cn/dave/article/131449http://www.cndba.cn/dave/article/131449
