### 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（安装Java看这里：[https://blog.csdn.net/qq\_43842093/article/details/116380855][https_blog.csdn.net_qq_43842093_article_details_116380855]）

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>
        
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            
            <exclusions>
                <exclusion>
                    <groupId>org.apache.zookeeper</groupId>
                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.5.8</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <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+"\t"+ 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
