Windows 平台安装 Nacos 2.x

环境准备

64 位操作系统，Windows 10 / Linux Centos 7
JDK 1.8

安装包下载

安装包下载官方地址：https://github.com/alibaba/nacos/releases

启动

将安装包解压到安装的目录下，改名为 nacos-2.0.4。然后进行到 bin 目录下，打开 CMD 窗口，使用如下命令以非集群模式启动服务。

startup.cmd -m standalone

如果要关闭 Nacos 服务，直接双击关闭脚本文件 shutdown.cmd 即可。

修改配置

为什么要修改配置？

遇到的问题：创建命名空间时，页面无反应，后端报错。默认数据库可能存在问题，故切换为mysql.

spring.sql.init.platform=mysql
db.num=1
db.url.0=jdbc:mysql://loclhos:3306/nacos?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai&useSSL=false&autoReconnect=true&rewriteBatchedStatements=true&useAffectedRows=true&allowMultiQueries=true
db.user.0=账户
db.password.0=密码
