基础准备

1.下载nacos-server-2.0.4.zip

地址：https://github.com/alibaba/nacos/releases/tag/2.0.4

2.执行sql文件nacos-mysql.sql，文件位于解压缩目录下nacos-server-2.0.4\nacos\conf

3.nacos-server-2.0.4\nacos\conf路径下配置文件application.properties里关于数据库的配置

上面db.num=1是配置的单数据源，如果配置多数据源的话，需要把所有的数据库链接配置都加到文件里面

4.进入到nacos-server-2.0.4\nacos\bin路径下，通过startup.cmd启动nacos服务

原因：直接启动cmd为集群启动nacos is starting with cluster，并且集群服务的ip列表是空的The server IP list of Nacos is []，所以我们首先以单机模式启动。

解决方法：两种方案，一种是修改配置启动文件startup.cmd，另一种是启动时通过命令，不是双击，并加上参数 -m standalone，如下：

方式一：修改文件startup.cmd：

方式二：命令行启动并添加参数， .\startup.cmd -m standalone

这样我们就可以通过单节点的方式启动nacos服务了 http://localhost:8848/nacos/index.html

默认用户名和密码：nacos

集群部署

上面我们直接启动的时候就是集群方案，但是由于节点为空，所以应该是没有配置节点的原因。我们找到解压路径下nacos-server-2.0.4\nacos\conf下的cluster.conf.example复制一份，并修改名称为cluster.conf.

然后修改里面的节点配置，格式为ip:端口（如果配置成回环地址，在节点中会看到两个，所以我们不用回环地址，不能写公网IP和127.0.0.1），另外注意需部署奇数个节点避免脑裂行为。

首先我们启动第一个节点。

然后再解压一份，按照上面的重复操作一波，但是需要把application.properties端口分别改成和我们的cluster.conf一致的端口：server.port=8850和server.port=8849。这样就完成了nacos的集群部署
