Nacos入门使用

一，Windows下安装nacos

到 https://github.com/alibaba/nacos/tags寻找合适的版本（我这里选择的是2.0.4），然后下载 nacos-server-2.0.4.zip，，Linux或Mac环境下载 nacos-server-2.0.4.tar.gz

然后在本地选择目录进行解压

由于nacos默认是使用集群环境，因此我们在**\nacos\bin目录下，打开startup,cmd文件，修改第26行

set MODE="cluster"
改成
set MODE="standalone"

然后双击startup.cmd，运行项目

"nacos is starting with standalone"

在浏览器访问 http://localhost:8848/nacos，输入账号/密码：nacos/nacos进行登录。

二，自定义配置

2.1 使用自定义端口

修改**\nacos\conf\application.properties文件

server.port=9000

在浏览器访问 http://localhost:9000/nacos，输入账号/密码：nacos/nacos进行登录。

2.2 配置MySQL

修改**\nacos\conf\application.properties文件

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
spring.datasource.platform=mysql

### Count of DB:
db.num=1

### Connect URL of DB:
db.url.0=jdbc:mysql://127.0.0.1:3306/xxx?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=root

找到**\nacos\conf\nacos-mysql.sql文件，在MySQL的xxx数据库中导入该文件执行

配置成功，重启

在浏览器访问 http://localhost:9000/nacos，输入账号/密码：nacos/nacos进行登录。

2.3 自定义密码登录

2.3.1 修改数据库

在MySQL的xxx数据库中，找到表users

用户名username是明文，password是BCrypt加密的密文

修改密码可以通过http://www.ab126.com/goju/10822.html等网站生成Bcrypt密码，或者自己编写代码获取

public static void main(String[] args) {
    System.out.println(new BCryptPasswordEncoder().encode("123456"));
}

记得引进spring-security-crypto依赖

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-crypto</artifactId>
    <version>5.6.2</version>
</dependency>

在浏览器访问 http://localhost:9000/nacos，输入账号/密码：nacos/123456进行登录。

2.3.2 通过页面修改

在nacos页面的【权限控制】- 【用户列表】，直接对用户修改密码
