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）

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
在这里插入图片描述
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><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-democloud: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);}
}
