### 服务器nacos-docker集群部署（阿里云服务器） ###

首先写贴上配置文件，与具体的操作，后面再叙述遇到的坑

部署环境

*  两台阿里云服务器
 *  一个mysql数据库（此处未配置mysql数据库高可用，只是配置了nacos的高可用）

部署的流程

*  clone项目

git clone https://github.com/nacos-group/nacos-docker.git
    cd nacos-docker

*  进入example，新建自己的docker-compose运行镜像的配置

cd example/
    vi nacos-config.yaml

version: "2"
    services:
      nacos:
        hostname: hbj-nacos
        image: nacos/nacos-server:latest
        container_name: nacos
        environment:
          - MODE=cluster # 集群模式
          - NACOS_SERVERS=IP1:PORT1,IP2:PORT2 # IP1,IP2是对应的服务器外网,PORT1,PORT2是对应的nacos服务端口
          - PREFER_HOST_MODE=hostname
          - NACOS_SERVER_IP=IP1 # 服务器外网
          - SPRING_DATASOURCE_PLATFORM=mysql
          - MYSQL_MASTER_SERVICE_HOST=MYSQLIP # mysql数据库对应的ip
          - MYSQL_MASTER_SERVICE_PORT=3306    # mysql数据库对应的端口
          - MYSQL_MASTER_SERVICE_DB_NAME=nacos 
          - MYSQL_MASTER_SERVICE_USER=root
          - MYSQL_MASTER_SERVICE_PASSWORD=password
          - MYSQL_DATABASE_NUM=1 # 数据源为1个
        volumes:
          - /home/nacos-docker/logs:/home/nacos/logs # 日志的挂在
        ports:
          - "8848:8848"
          - "9555:9555"
        restart: on-failure

*  执行命令：

cd ..
    docker-compose -f example/nacos-config.yaml up -d

*  nacos便启动起来了（另一台服务器只需要修改对应的NACOS\_SERVER\_IP即可）

额外的补充

nacos项目对应的github地址 [https://github.com/alibaba/nacos][https_github.com_alibaba_nacos]

期间遇到的坑

*  未配置NACOS\_SERVER\_IP导致找不到集群的节点列表

原因：因为nacos是部署在docker容器中的，它是用的是内网的地址，然而nacos的集群配置是在多台服务器上的，导致服务器之间不能互相访问通，只需要配置上对应的NACOS\_SERVER\_IP即可

报错样例：

nacos管理页面上访问对应接口：

[http://IP:8848/nacos/v1/ns/operator/cluster/states?withInstances=false&pageNo=1&pageSize=10&keyword=&namespaceId=][http_IP_8848_nacos_v1_ns_operator_cluster_states_withInstances_false_pageNo_1_pageSize_10_keyword_namespaceId]

接口返回的内容：

code:503 msg: server is STARTING now, please try again later!

查看对应的日志:

可以发现出现的原因是找不到对应的节点
