# 4.linux环境启停 #

3.1 解压  
把我们的Nacos包解压 tar -zxvf nacos-server-1.1.4.tar.gz

cd nacos  
cd bin  
sh startup.sh -m standalone \# 单独启动要加上 -m standalone 集群启动直接就是 startup.sh  
cat /usr/local/springcloud-alibaba/nacos/logs/start.out 查看日志 默认端口8848

# 5.Nacos client服务端的搭建 #

1.  加入依赖

<dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring‐cloud‐alibaba‐nacos‐discovery</artifactId>
    </dependency>

1.  加注解@EnableDiscoveryClient ，高版本也可以不加

![在这里插入图片描述][20200306174224668.png]

1.  appication.yml文件

spring:
      cloud:
        nacos:
          discovery:
            server-addr: 192.168.73.132:8848 # #配置nacos的配置中心         132虚拟机
      application:
        name: nacos-test

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjQzNzYzMw_size_16_color_FFFFFF_t_70 5]

1.  验证我们的order-center注册到我们的nacos上

@RequestMapping
    @RestController
    public class TestController { 
        @Autowired
        private DiscoveryClient discoveryClient;
    
        @GetMapping("/getServiceList")
        public List<ServiceInstance> getServiceList() { 
    
            List<ServiceInstance> serviceInstanceList = discoveryClient.getInstances("nacos-test");
            return serviceInstanceList;
        }
    
    }

访问 http://localhost:8080/getServiceList

## 6.1 启动nginx ##

nginx配置

user root;
    worker_processes  1;
    
    pid        /usr/local/nginx/logs/nginx.pid;
    
    events { 
        worker_connections  1024;
    }
    
    
    http { 
        include       mime.types;
        default_type  application/octet-stream;
        # 负载均衡配置  配置在http模块
        upstream nacoscluster{ 
         server 192.168.73.132:8849;
         server 192.168.73.132:8850;
         server 192.168.73.132:8851;
       }
    
        server { 
              listen                   8847;
              server_name              localhost;
              location /mynacos/ { 
                    proxy_pass         http://nacoscluster/nacos/;
              }
            }
    }

访问地址 http://192.168.73.132:8847/mynacos/

## 6.2 安装 我们的nacosserver ##

(搭建三个集群端口分别为8849 ,8850,8851)

我们以配置一台为例（8849）为例

1.  修改nacos8849/conf文件 application.properties

server.port=8849   #要改的端口号
    
    spring.datasource.platform=mysql
    # 数据库实例数量
    db.num=1
    #自己数据库的连接信息
    db.num=1
    #自己数据库的连接信息
    db.url.0=jdbc:mysql://192.168.174.1:3306/nacos_test?characterEncoding=utf8&connectTimeout=
    1000&socketTimeout=3000&autoReconnect=true
    db.user=root
    db.password=root

1.  将cluster.conf.example改成cluster.conf  
    将集群ip记录下来

192.168.73.132:8849
    192.168.73.132:8850
    192.168.73.132:8851

1.  需要修改nacos-server的 启动脚本jvm参数 (原谅我的笔记本内存太小)  
    vim startup.sh

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjQzNzYzMw_size_16_color_FFFFFF_t_70 8]  
虚拟机较小，修改为  
\-Xms512m -Xmx512m -Xmn256m

1.  最后一步：创建一个数据库（需要自己创建一个数据库） 脚本的位置在 nacos/conf/nacos-mysql.sql
2.  启动

sh startup.sh 
    cat /usr/local/springcloud-alibaba/nacos-cluster/nacos8849/logs/start.out  查看日志 默认端口8848

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjQzNzYzMw_size_16_color_FFFFFF_t_70 9]

分别访问  
http://192.168.73.132:8849/nacos/index.html  
http://192.168.73.132:8850/nacos/index.html  
http://192.168.73.132:8851/nacos/index.html

ng访问  
http://192.168.73.132:8847/mynacos/

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjQzNzYzMw_size_16_color_FFFFFF_t_70 10]  
配置完了集群，以后java’代码就可以直接写 8847的ng地址呢

spring:
      cloud:
        nacos:
          discovery:
            server-addr: 192.168.73.132:8847 # ngix配置的集群地址
      application:
        name: nacos-test
