一.nacos下载安装

1.下载

nacos官网：https://nacos.io

nacos下载地址：https://github.com/alibaba/nacos/releases

下载tar.gz包或者zip包

2.安装

1. 将安装包上传到linux系统
   解压：tar -zxvf nacos-server-1.1.4.tar.gz
   或者：gzip -d nacos-server-1.1.4.zip
   
   目录结构如上图 安装完成

3.更改配置

2. 更改配置（集群模式）
   cd conf
   cp cluster.conf.example cluster.conf
   文件中加入配置（集群的IP地址）
   10.10.94.201
   10.10.94.202
   10.10.94.203
   保存
   3.更改application.properties
   vim application.properties
   新增配置（数据库）用于保存nacos的用户信息等：
   db.num=1
   db.url.0=jdbc:mysql://10.10.94.202:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
   db.user=root
   db.password=root
3. 建表
   在mysql执行如下建表语句：

SET FOREIGN_KEY_CHECKS=0;

至此，nacos基本配置就完成了
打开浏览器，访问：http://10.10.94.202:8848/nacos

4.用户名密码配置

1. 数据库插入如下语句：
   INSERT INTO nacos_config.users (username, password, enabled) VALUES (‘nacos’, ‘$2a$10$NJMHBO/0vlGPjiYEYE5H3OTvb946LCCYsHvU5aBLBztukJqE04Sba’, ‘1’);
   用户名:nacos
   密码：123456
   登入成功后如图：
   
2. 更改密码
   引入maven依赖

    <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    
    写一个main方法，用下面方法生成密码，update到数据库users表
    
    
    
    public class PasswordEncoderUtil {
 
    public static void main(String[] args) {
        System.out.println(new BCryptPasswordEncoder().encode("nacos"));
    }
}
