-server : 定义agent运行在server模式
-bootstrap-expect : 在一个datacenter中期望提供的server节点数目，当该值提供的时候，consul一直 等到达到指定sever数目的时候才会引导整个集群，该标记不能和bootstrap共用
-bind: 该地址用来在集群内部的通讯，集群内的所有节点到地址都必须是可达的，默认是0.0.0.0 -node:节点在集群中的名称，在一个集群中必须是唯一的，默认是该节点的主机名
-ui: 启动web界面
-rejoin: 使consul忽略先前的离开，在再次启动后仍旧尝试加入集群中。
-config-dir:: 配置文件目录，里面所有以.json结尾的文件都会被加载
-client: consul服务侦听地址，这个地址提供HTTP、DNS、RPC等服务，默认是127.0.0.1所以不对外提供服 务，如果你要对外提供服务改成0.0.0.0
-join : 启动时加入这个集群
-datacenter：数据中心名称，缺省值为dc1。
-enable-script-checks： 检查服务是否处于活动状态，类似开启心跳。
