nacos集群部署

1、mysql数据库部署

version: '3.2'
services:
  mysql:
    image: "library/mysql:5.7.8"
    container_name: mysql
    hostname: docker-mysql
    environment:
      MYSQL_ROOT_PASSWORD: "root"
      TZ: Asia/Shanghai
    restart: always
    volumes:
      - "./data:/var/lib/mysql"
      - "./conf/my.cnf:/etc/my.cnf"
    ports:
      - "3306:3306"

networks:
  default:
    external:
      name: app_net

./conf/my.cnf配置文件

[mysqld]
user=mysql
default-storage-engine=INNODB
character-set-server=utf8mb4
[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb4

2、部署mysql成功后，连接mysql数据库，执行脚本nacos.sql，初始化数据库：

DROP DATABASE IF EXISTS `nacos_dev`;

CREATE DATABASE  `nacos_dev` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

create user 'nacos' identified by 'nacos';
grant all on nacos_dev.* to 'nacos'@'%';

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

USE nacos_dev;

version: "3.2"
services:

    container_name: nacos01
    hostname: nacos01
    env_file:
      - ./env/nacos-mysql.env
    environment:
      TZ: Asia/Shanghai
    volumes:
      - ./logs/nacos01/:/home/nacos/logs
      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8849:8848"
      - "9555:9555"
    restart: always

  nacos02:
    image: nacos/nacos-server:1.4.0
    container_name: nacos02
    hostname: nacos02

      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8850:8848"
    restart: always

  nacos03:
    image: nacos/nacos-server:1.4.0
    container_name: nacos03
    hostname: nacos03
    env_file:
      - ./env/nacos-mysql.env

      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8851:8848"
    restart: always

networks:
  default:
    external:
      name: app_net

./env/nacos-mysql.env配置文件

启动nacos

docker-compose -f docker-compose.yml up -d

4、配置nginx负载均衡，以方便在代码中的配置

nacos.conf文件内容如下，注意将超时时间设置大一些：

server{
    listen 8848;
    server_name localhost;
    charset utf-8;
    client_max_body_size 50M;

    location /nacos{
        proxy_pass http://backend;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_intercept_errors on;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 300;
        proxy_send_timeout 150;
        proxy_read_timeout 150;
    }
    
}
upstream backend {
    ip_hash;
    server 192.168.1.8:8849    ;
    server 192.168.1.8:8850 weight=5;
    server 192.168.1.8:8851;
}

5、访问nacos

通过http://192.168.1.8:8848/nacos访问nacos界面，用户名和密码都是nacos
