4查看集群状态
--清理全部容器实例
docker stop $(docker ps -q) & docker rm $(docker ps -aq)
--查看节点
docker exec -t node1 consul members
--查看主从信息
docker exec -t node1 consul operator raft list-peers
--集群参数get/set测试
docker exec -t node1 consul kv put eleven 11
docker exec -t node2 consul kv get eleven
docker exec -t node4 consul kv get eleven
docker exec -t node4 consul kv put seven 7
--关闭leader
docker stop id
查看状态
docker logs -f node2
kill还有2个时可以选举，只剩1个就集群失败，数据不丢失的，可以重新挨个儿启动
firewall-cmd --zone=public --add-port=8500/tcp --permanent
systemctl restart firewalld.service
firewall-cmd --reload
firewall-cmd --list-ports
#重启 Docker 服务：有时候，重启 Docker 服务可能能解决这个问题。你可以使用以下命令来重启 Docker 服务：
sudo systemctl restart docker
--查看节点
docker exec -t node1 consul members
--查看主从信息
docker exec -t node1 consul operator raft list-peers
--启停节点做测试查看
docker stop node1
docker start node1
docker exec -t node2 consul operator raft list-peers
#安装nginx
mkdir /mydata/consulnginx
cd /mydata/consulnginx
chmod 777 /mydata/consulnginx
docker run -d -p 15500:80 -v /mydata/consulnginx/:/var/log/nginx/ -v /mydata/consulnginx/nginx.conf:/etc/nginx/nginx.conf --name consulnginx nginx
