nacos连接了本地得redis怎么修改 nacos连接oracle

一、下载nacos服务端：

访问：https://nacos.io/  

进入下载源码和服务端程序的地方：

往下翻： 

点击：

往下看翻，找到服务 下载的地方，这是最新的  版本，后面还有其他版本：

下载后解压配置，连接mysql 执行初始化脚本：nacos\conf\nacos-mysql.sql  数据库脚本文件。

客户端执行：

生成表：

配置数据库信息  \nacos\conf\application.properties  目录 文件下添加：

spring.datasource.platform=mysql
db.num=1 
db.url.0=jdbc:mysql://10.130.16.246:3019/ZIPKIN?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true 
db.user.0=mysql
db.password.0=mysql

如图： 

 

也可，亲测OK：

启动nacos服务：

nacos\bin\startup.cmd    双击“startup.cmd”启动nocas服务

这种启动方式同样有弊端，在关闭命令窗口后nacos进程会直接shutdown，导致服务停止。
解决方法：
新建一个记事本，输入如下代码：

Set ws = CreateObject("Wscript.Shell")
 ws.run "cmd /c startup.cmd",vhhide

把记录本文件命名：***.vbs 如 runbat.vbs，然后双击运行runbat.vbs文件

启动成功：

如果是1.4版本 还需要设置单机启动，配置文件 nacos\bin\startup.cmd 配置内容

set MODE="cluster" 改成如下图这样 set MODE="standalone"：

如果不改，启动报错如下：

ERROR Startup errors :

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat
        at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.onRefresh(ServletWebServerApplicationContext.java:156)
        at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:544)

        at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:391)
        at org.springframework.boot.SpringApplication.run(SpringApplication.java:312)

或者 用命令窗口，进入到安装路径的bin目录下，执行：

sh startup.sh -m standalone

访问如下地址：

http://172.21.12.11:8848/nacos/index.html

用户名和密码 均为：nacos ,s首次登陆页面：

 创建命名空间：

 成功生成：

配置列表里出现：

创建配置列表：这是配置中心  配置内容具体写：！！！！ 

点击发布按钮后，返回后显示列表：

此时可以在对应的客户端项目中 配置：bootstrap.yml

spring:
  profiles:
    #Data Id 的后缀 即此处  nandao-demo-dev.yml的 dev（最后一个横杆和点之前的字符串）
    active: dev
  application:
    #微服务名称
    name: nandao-oms
  cloud:
    nacos:
      config:
        #自定义配置
        #nacos服务器的地址
        server-addr: 172.21.12.11:8848
        #nacos服务器的命名空间
        namespace: cee09d5e-e6ad-4c68-847c-733ed2246bbb
        #组别
        group: nandao
        #配置文件类型
        file-extension: yml
        #Data Id 的前缀 即此处  nandao-demo-dev.yml的前缀
        prefix: nandao-demo
      #注册中心配置
      discovery:
        server-addr: 172.21.12.11:8848
        namespace: cee09d5e-e6ad-4c68-847c-733ed2246bbb

或者在这里配置

服务列表看是否注册成功：

 并且可以创建多个命名空间：同时可以从一个 克隆的另一个：举例

 克隆成功：

导出功能： 

 这就是web端简单的使用

二、客户端流程：

1、jar引入：

<dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

2、启动类加注解：@EnableDiscoveryClient

3、 配置文件创建（上面也有详细的介绍）：bootstrap.yml

spring:
  profiles:
#    active: dev
    active: local
  application:
    name: admin-oms
  cloud:
    nacos:
      config:
        #自定义配置
#        server-addr: 10.130.64.189:8848
        server-addr: 10.130.64.189:8848
        namespace: bab5e416-0b7d-4cef-b421-d06b6d0f4c67
        group: nmp-oms
        file-extension: yml
        prefix: nmp-oms

      discovery:
        server-addr: 10.130.64.189:8848
        namespace: bab5e416-0b7d-4cef-b421-d06b6d0f4c67
#        server-addr: 10.130.64.189:8848
#        namespace: a1ed9d55-3917-46e4-93fd-30232ff50545

启动后：
