一、注意

nacos搭建集群比较麻烦，需要有个数据库做为数据同步。nacos给出了具体的数据库mysql。

以下是我上传的nacos脚本

也可以自己下载里面可能没有新建数据库的语句需要自己加上。

DROP DATABASE IF EXISTS `nacos`;
CREATE DATABASE `nacos` DEFAULT CHARACTER SET utf8;
USE `nacos`;

二、nacos配置文件

1、application.properties文件（加上的部分）

# 配置nacos集群nacos注册中心数据联系的数据库
spring.datasource.platform=mysql
db.num=1
# 使用的是主机名不是ip地址访问，请保证nacos和mysql数据库在同一网段
db.url.0=jdbc:mysql://mysql-nacos:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=123456

2、application.properties文件完整版配置文件

pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;
    
    upstream nacos {   
      server nacos1:8848;
      server nacos2:8848;
    }

    # 导入其他配置文件的内容
    #include /etc/nginx/conf.d/*.conf;

server {
    listen       8848;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        #root   /usr/share/nginx/html;
        #index  index.html index.htm;
        proxy_pass http://nacos;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}
}

四、docker-compones文件

version: '2'
services:
  mysql:
    # 根据mysql:5.7镜像生成容器格式：名字:版本
    image: mysql:5.7
    # 网络中主机名
    hostname: mysql-nacos
    # 容器镜像名
    container_name: mysql-nacos
    # 最大内存大小
    mem_limit: 512M
    # 对外暴露的端口格式：宿主机端口:容器端口
    ports:
     - 13306:3306
     
  nginx:
    image: nginx
    hostname: nginx-nacos
    container_name: nginx-nacos
    mem_limit: 512M
    ports:
     - 8848:8848
    # 将容器文件挂载宿主机格式：宿主机文件位置:容器文件位置
    volumes:
     - ./nginx/log:/var/log/nginx
     - ./nginx/conf/nginx.conf:/etc/nginx/nginx.conf
     - ./nginx/conf.d:/etc/nginx/conf.d
     
  nacos1:
    image: nacos/nacos-server
    hostname: nacos1
    container_name: nacos1
    mem_limit: 512M
    # 给予容器：真正的root的权限
    privileged: true
    ports:
     - 18848:8848
    volumes: #挂载
     - ./nacos1:/home/nacos/logs
     - ./nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties
     - ./nacos/conf/application.properties:/home/nacos/conf/application.properties
    # 环境参数
    environment:
     # 什么模式：集群模式
     MODE: cluster
     # 电脑的识别方式：主机名识别
     PREFER_HOST_MODE: hostname
     # 集群包含的服务器：用逗号隔开
     NACOS_SERVERS: nacos1:8848,nacos2:8848
     
  nacos2:
    image: nacos/nacos-server
    hostname: nacos2
    container_name: nacos2
    mem_limit: 512M
    privileged: true
    ports:
     - 18849:8848
    volumes:
    # 日志文件挂载到宿主机
     - ./nacos2:/home/nacos/logs
    # 客户端管理配置文件挂载到宿主机
     - ./nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties
    # nacos集群配置文件挂载到宿主机
     - ./nacos/conf/application.properties:/home/nacos/conf/application.properties
    environment:
     MODE: cluster
     PREFER_HOST_MODE: hostname
     NACOS_SERVERS: nacos1:8848,nacos2:8848

# 设置网络
networks:
  default:
   external:
      # 创建好的网络的名字：之所以设置是要把mysql和nacos的网络在同一频道，保证其可以正常访问。
      name: jt47

五、运行docker-componse文件创建

命令：docker-compose up（创建文件中所有的容器）

docker-compose up nacos1（创建文件中容器标签为：nacos1容器）

六、注意：

1. 要保证mysql和nacos在同一网段下，不然数据无法进行共享
networks: default: external: name: jt47（网络名称）2. 要给予nacos真正的nacos权限（不设置的时候是普通的root权限）：
privileged：true3. 环境参数：
1. 要保证是集群模式
environment: MODE: cluster2. 要保证能够访问nacos设置使用主机名识别连接（因为ip地址是可变的）
environment:
PREFER_HOST_MODE: hostname3. 配置nacos集群nacos服务ip
environment:
NACOS_SERVERS: nacos1:8848,nacos2:88484. 要为客户端管理配置文件加上一句内容（custom.properties文件）
management.endpoints.web.exposure.include=*
