codis3.2安装报错dashboard.go:369: [PANIC] call rpc create-proxy to dashboard 127.0.0.1:18080 failed的处理
执行以下命令时报错：

知乎上的答案：https://www.zhihu.com/question/52519151，感觉没有说清楚问题和解决办法
实际上经过看前面的启动dashboard命令：
官方文档是这样启动dashboard的
nohup ./bin/codis-dashboard --ncpu=4 --config=dashboard.toml \ --log=dashboard.log --log-level=WARN &
问题出在--config=dashboard.toml上，没有显示指定config文件，就用默认的，而实际上我们需要启动自己的配置文件
加上config即可，如下：
[root@node1 codis]# nohup ./bin/codis-dashboard --ncpu=1 --config=config/dashboard.toml --log=dashboard.log --log-level=WARN >> /var/log/codis_dashboard.log &
