consul 部署

• consul集群需要至少两个consul server节点

参数说明：
     -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
     -data-dir:提供一个目录用来存放agent的状态,所有的agent允许都需要该目录,该目录必须是稳定的,系统重启后都继续存在
     -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
     -bind:：指明节点的IP地址，一般是0.0.0.0或者云服务器内网地址，不能写阿里云外网地址。这是Consul侦听的地址，它必须可以被集群中的所有其他节点访问。虽然绑定地址不是绝对必要的，但最好提供一个。
     -ui: 启动web界面
     -config-dir::配置文件目录,里面所有以.json结尾的文件都会被加载
     -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。
     -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

docker exec consul_server_1 consul operator raft list-peers

docker exec consul_server_11 consul operator raft list-peers

server 有三个，client有一个

安装nginx

apt-get install nginx

nginx -v

nginx config

 server {
  listen 8500;
  location / {
  proxy_pass http://xdpconsul;
  proxy_redirect default;
  }
  }

  upstream xdpconsul {
  server 127.0.0.1:8510 weight=2;
  server 127.0.0.1:8520 weight=1;
  server 127.0.0.1:8530 weight=1;
  }
