etcd installation and deployment steps

I was through direct yum install ( yum install etcd -y), which generated configuration file /etc/etcd/etcd.conf.

Here sub-clusters and stand-alone version to introduce configuration items

ETCD_WAL_DIR: The default is empty, set the path, you can write WAL alternative data file is written, the operating loss with less risk;
ETCD_LISTEN_CLIENT_URLS: URL inform the client, because of its exposure to the RESTFUL API, for interacting, cloud server attention to the internal network ip + 2379 (default listen port), do not set it, other hosts can not access the large column  etcd installed deployment steps ; :
