Nacos学习与实践(一):Docker 集群部署 Nacos3.0

Nacos学习与实践(一):Docker 部署 Nacos3.0 集群

引言

  • Nacos最近新出了3.0版本,较2.0版本做出较大改动,架构升级了,推出了MCP Registry API,从传统的动态服务发现、配置管理和服务管理平台正在逐步向AI方向发展。
  • 我所在公司正在搭建技术架构而且有AI方面的开发需求,Nacos3.x完全契合我现在的需求,打算部署一套Nacos3.0进行学习。
  • 单机部署比较简单,目前容器化部署还是比较主流的,所以我直接选择docker集群部署,至于k8s集群部署后面有时间了再说。
  • Nacos社区提供了一系列的docker compose文件,可以参考这些文件适配更多场景的Nacos部署。

准备工作

  • 环境要求
    • 准备了三台虚拟机作为集群节点,三台机器都需要安装Docker以及docker-compose,docker以及docker-compose安装教程这里不做赘述。
    • 准备一台mysql服务器,mysql版本大于5.7,我这里用的是8.0。
    • 网络互通配置,需要开通端口:8080,8848,7848,9848,9849。
  • 镜像选择
    • 官方 Nacos 镜像版本,我这里用的是3.0.1(nacos/nacos-server:v3.0.1)。

部署方式

Nacos官方提供了三种集成部署方式:

  • 直连IP模式:<http://ip:port/openAPI>
  • 挂载SLB模式:<http://SLB:port/openAPI>
  • 域名+SLB模式:<http://xxx.com:port/openAPI>(官方推荐)

Nacos 集群节点一览

节点ip主机名称部署服务
10.116.66.71nacos1nacos
10.116.66.104nacos2nacos
10.116.66.115nacos3nacos
10.116.66.70mysqlmysql

开始部署(此流程为单节点流程,其余两个节点重复此流程即可)

  1. 创建挂载目录
mkdir -p /usr/local/nacos/logs
mkdir -p /usr/local/nacos/data
touch /usr/local/nacos/application.properties
touch /usr/local/nacos/cluster.conf
  1. 编写application.properties文件(源自Github,可自行下载)

  1. 数据库初始化(去上面文件指定数据库执行mysql-schema.sql即可)
  2. 执行naocs-compose.yaml文件
docker-compose -f nacos-compose.yaml up
  1. 服务启动成功,其余节点按上述流程再走一遍即可

存在问题

虽然Nacos启动成功了,但我这里还有两个问题没有解决,这两个问题不影响Nacos的使用,如果有遇到相同问题并解决的大佬麻烦评论区留言告知一下,万分感谢。

  • 第一点:用docker启动后,如上图所示,控制台的ip是172.19.0.2,这个IP如何更改?
  • 第二点:在部署方式上,我本来计划选用的是官方推荐的第三种方式,即域名+SLB模式,拜托运维同事帮忙开通了域名以及SLB配置,用SLB的IP访问配置中心没有问题,切成域名访问就报错,就很奇怪,所以目前还是用的SLB的IP进行的部署。

### 使用 Docker Swarm 部署 Nacos 单节点集群 #### 准备工作 Nacos 集群部署依赖于 Docker Swarm 集群,在此之前需确保已将运行 Nacos 实例的 Docker 节点加入到 Swarm 中[^1]。 #### 创建可对接网络 由于 `docker stack deploy` 命令无法创建新的可对接 (attachable) 网络,因此必须提前使用 `docker network create` 定义该类型的网络,并将其设置为外部可用。具体操作如下: ```bash docker network create --driver=overlay --attachable nacos-network ``` 这条命令会创建个名为 `nacos-network` 的 overlay 类型网络并允许容器连接至该网络[^2]。 #### 编写 Compose 文件 准备份用于描述服务配置的 YAML 文件 (`docker-compose.yml`) ,其内容应至少包含以下部分: ```yaml version: &#39;3.8&#39; services: nacos-server: image: nacos/nacos-server:v2.0.3 environment: MODE: standalone networks: - nacos-network ports: - "8848:8848" networks: nacos-network: external: true ``` 上述文件指定了单机模式下启动 Nacos 所必需的各项参数以及端口映射关系;同时声明了所使用的自定义网络名称外部属性相匹配。 #### 启动服务栈 完成以上准备工作之后,可以通过执行下面的指令来启动整个应用堆栈: ```bash docker stack deploy -c docker-compose.yml nacos-cluster ``` 这步骤将会依据所提供的 compose 文件中的定义向 Swarm 发送请求以构建和管理组关联的服务集合——即所谓的“服务栈”,此处命名为 `nacos-cluster`。 旦所有组件都成功启动并正常运作,则意味着已经完成了基于 Docker Swarm 平台之上针对单主机环境下的 Nacos 微服务体系注册中心实例的成功部署
