docker swarm 各节点无法正常连接

[weixin_35772245]

如题，在配置好swarm后，启动swarm服务。
但是在查看信息时发现，所有节点都无法正常连接，但是swarm服务确实已经启动。
而且已经在配置文件中添加：OPTIONS='-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock'
输入sudo docker -H 192.168.101.66:2376 info
内容如下
Containers: 0
Images: 0
Role: primary
Strategy: spread
Filters: health, port, containerslots, dependency, affinity, constraint
