linux服务器安装zookeeper本地项目远程连接

zookeeper linux 服务器安装，本地idea连接

先决条件：一台linux服务器，服务器里面已经安装好java环境（自行百度）

 

mkdir zookeeper #创建文件夹
​
cd zookeeper    #进入文件夹
​
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.5.8/apache-zookeeper-3.5.8-bin.tar.gz    #下载zookeeper，这个是编译后的二进制包
​
tar -zxvf apache-zookeeper-3.5.8-bin.tar.gz     #解压安装包
​
cd apache-zookeper-3.5.8-bin        #进入解压后的文件夹
cd conf     #进入配置文件夹
cp zoo_sample.cfg zoo.cfg       #复制配置文件zoo_sample.cfg并命名为zoo.cfg
​
vi zoo.cfg      #编辑配置文件 s编辑，esc + :wq保存退出
​
vi /etc/profile     #配置系统环境变量
#加上下面内容 路径根据实际情况修改
export ZOOKEEPER_HOME=/usr/zookeeper/apache-zookeeper-3.5.7-bin/
PATH=$ZOOKEEPER_HOME/bin:$PATH
​
source /etc/profile     #让刚刚添加的配置生效
​
#切换到bin目录
cd ..
cd bin
​
./zkServer.sh start     #启动服务
./zkServer.sh status    #查看状态
./zkServer.sh stop      #关闭服务
tail 日志文件名称         #查看日志(存放在logs目录)
./zkCli.sh              #打开客户端

zookeeper服务就搭建好了

 

在阿里云控制台把2181端口放开，配置安全组规则

 

准备就绪，实现代码

新建maven项目，引入依赖

<dependencies>
    <!-- SpringBoot整合Web组件 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- SpringBoot整合zookeeper客户端 -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
        <!--先排除自带的zookeeper3.5.3-->
        <exclusions>
            <exclusion>
                <groupId>org.apache.zookeeper</groupId>
                <artifactId>zookeeper</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <!--添加zookeeper3.4.9版本-->
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.5.8</version>
    </dependency>

        <optional>true</optional>
    </dependency>
    <dependency>

        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

 

建application.yml文件

#8004表示注册到zookeeper服务器的服务提供者端口号
server:
  port: 8004
​
​
#服务别名----注册zookeeper到注册中心名称
spring:
  application:
    name: cloud-zookeeper-demo
  cloud:
    zookeeper:
      connect-string: 阿里云公网IP:2181

 

controller层

@RestController
public class PaymentController {
​
    @Value("${server.port}")
    private String serverPort;
​
    @RequestMapping(value = "/payment/zk")
    public String paymentZk(){
        return "springcloud with zookeeper: "+serverPort+"	"+ UUID.randomUUID().toString();
    }
}

 

启动类

@SpringBootApplication
@EnableDiscoveryClient //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
public class PaymentMain8004 {
​
    public static void main(String[] args) {
        SpringApplication.run(PaymentMain8004.class,args);
    }
}

 

启动不报错，访问后的结果
