Nacos高可用集群搭建排坑版

Myth丶恋晨 2023-10-01 09:28 21阅读 0赞

## 一、环境准备 ##

### 1、项目下载/服务配置 ###

官方下载地址：[https://github.com/alibaba/nacos/releases/download/2.0.3/nacos-server-2.0.3.zip][https_github.com_alibaba_nacos_releases_download_2.0.3_nacos-server-2.0.3.zip]

1）解压上述压缩包，进入到conf目录，修改配置（外部MySQL连接），如下：

### 端口号
    server.port=8848
    
    ### Specify local server's IP，本机启动nacos服务IP
    nacos.inetutils.ip-address=127.0.0.1
    
    ### 数据存储方式使用MySQL
    spring.datasource.platform=mysql
    
    ### Count of DB:
    db.num=1
    
    ### Connect URL of DB，数据库连接信息
    db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
    db.user.0=root
    db.password.0=123456

注意：数据连接信息中的db.url中最后一定要加上`&serverTimezone=UTC`，否则在一些老版本中启动nacos server会报异常。

2）在 Nacos 的解压目录 nacos/conf 目录下，复制配置文件 cluster.conf.example 并重命名为 cluster.conf，每行配置为每个nacos服务所在机器的 ip:port；例如：

### 将示例文件改为集群配置文件
    cp cluster.conf.example cluster.conf
    
    vim cluster.conf
    
    ### 将3个机器的IP和端口写到集群配置文件中
    127.0.0.1:8848
    127.0.0.1:8849
    127.0.0.1:8850

### 2、MySQL数据库创建 ###

Nacos项目源码官方下载地址：  
[https://github.com/alibaba/nacos/archive/refs/tags/2.0.3.zip][https_github.com_alibaba_nacos_archive_refs_tags_2.0.3.zip]

SQL源文件地址在 nacos-2.0.3 解压目录./distribution/conf 的目录下；

首先要自己创建nacos\_config数据库，然后在运行nacos-mysql.sql文件内容：

### 3、服务启动 ###

#### 1）单机方式启动一个实例 ####

### 进入解压目录
    nohup sh ./bin/startup.sh -m standalone &

注意：如果`数据库连接信息错误`或者 老版本Nacos的db.url信息中没有加`&serverTimezone=UTC`，会报如下错误：
