springcloud consul 搭建docker 集羣（1）

springcloud consul 搭建docker 集羣（1）

1、 建3個server節點 和1個client節點

• 配置docker 網絡

  sudo docker network create --subnet=172.18.0.0/24 consulnet
  

• 創建配置文件

  • 創建文件夾 consul_client_config ， consul_server_config）
  • 創建文件 consul_client_config/basic_config_1.json

    	{
    "datacenter": "dc1",
    "log_level": "INFO",
    "node_name": "c1",
    "server": false,
    "bind_addr": "0.0.0.0",
    "client_addr": "0.0.0.0",
    "ui": false,
    "ports": {
        "dns": 8600,
        "http": 8500,
        "https": -1,
        "server": 8300,
        "serf_lan": 8301,
        "serf_wan": 8302
    },
    "rejoin_after_leave": true,
    "retry_join": [
       "172.18.0.2",
        "172.18.0.3",
        "172.18.0.4"
    ],
    "retry_interval": "30s",
    "reconnect_timeout": "72h"
    }
    

  • 創建文件 consul_server_config/basic_config_1.json

  	{
      "datacenter": "dc1",
      "log_level": "INFO",
      "node_name": "s_1",
      "server": true,
      "bootstrap_expect": 2,
      "bind_addr": "0.0.0.0",
      "client_addr": "0.0.0.0",
      "ui": true,
      "ports": {
          "dns": 8600,
          "http": 8500,
          "https": -1,
          "server": 8300,
          "serf_lan": 8301,
          "serf_wan": 8302
      },
      "rejoin_after_leave": true,
      "retry_join": [
          "172.18.0.2",
          "172.18.0.3",
          "172.18.0.4"
      ],
      "retry_interval": "30s",
      "reconnect_timeout": "72h"
  }
  
  

  • 創建文件 consul_server_config/basic_config_2.json

  	{
      "datacenter": "dc1",
      "log_level": "INFO",
      "node_name": "s_2",
      "server": true,
      "bootstrap_expect": 2,
      "bind_addr": "0.0.0.0",
      "client_addr": "0.0.0.0",
      "ui": true,
      "ports": {
          "dns": 8600,
          "http": 8500,
          "https": -1,
          "server": 8300,
          "serf_lan": 8301,
          "serf_wan": 8302
      },
      "rejoin_after_leave": true,
      "retry_join": [
          "172.18.0.2",
          "172.18.0.3",
          "172.18.0.4"
      ],
      "retry_interval": "30s",
      "reconnect_timeout": "72h"
  }
  
  

  • 創建文件 consul_server_config/basic_config_3.json

  	{
      "datacenter": "dc1",
      "log_level": "INFO",
      "node_name": "s_3",
      "server": true,
      "bootstrap_expect": 2,
      "bind_addr": "0.0.0.0",
      "client_addr": "0.0.0.0",
      "ui": true,
      "ports": {
          "dns": 8600,
          "http": 8500,
          "https": -1,
          "server": 8300,
          "serf_lan": 8301,
          "serf_wan": 8302
      },
      "rejoin_after_leave": true,
      "retry_join": [
          "172.18.0.2",
          "172.18.0.3",
          "172.18.0.4"
      ],
      "retry_interval": "30s",
      "reconnect_timeout": "72h"
  }
  
  

  • 文件如下
    
  • 複製文件到 /opt/config/consul/

    cp -rf ./consul_server_config  /opt/config/consul/
    cp -rf ./consul_client_config  /opt/config/consul/
    

• docker 命令

  -- server
  
  sudo docker run -d  --name consul_s1 --net consulnet  --ip 172.18.0.2 --restart always -v /etc/localtime:/etc/timezone:rw -v /etc/localtime:/etc/localtime:rw  -v /opt/config/consul/consul_server_config/basic_config_1.json:/consul/config/basic_config_1.json  consul agent -config-dir /consul/config
  
  sudo docker run -d  --name consul_s2 --net consulnet  --ip 172.18.0.3 --restart always -v /etc/localtime:/etc/timezone:rw -v /etc/localtime:/etc/localtime:rw  -v /opt/config/consul/consul_server_config/basic_config_2.json:/consul/config/basic_config_1.json  consul agent -config-dir /consul/config
  
  sudo docker run -d  --name consul_s3 --net consulnet  --ip 172.18.0.4 --restart always -v /etc/localtime:/etc/timezone:rw -v /etc/localtime:/etc/localtime:rw -v /opt/config/consul/consul_server_config/basic_config_3.json:/consul/config/basic_config_1.json  consul agent -config-dir /consul/config
  
  -- client agent
  
  sudo docker run -d -p 8500:8500 -p 8600:8600 -p 8300:8300 -p 8301:8301 -p 8302:8303 --name consul_c1 --net consulnet  --ip 172.18.0.5 --restart always -v /etc/localtime:/etc/timezone:rw -v /etc/localtime:/etc/localtime:rw -v /opt/config/consul/consul_client_config/basic_config_1.json:/consul/config/basic_config.json  consul agent -config-dir /consul/config
  

• 打開 http://172.18.0.2:8500
  
  沒有 api-gateway 和 testwebapp 項目
