## 一、【linux】-安装zookeeper ##

**1、安装jdk**

1、下载jdk  
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzMjI5NTQz_size_16_color_FFFFFF_t_70]  
**注意：**  
不要使用wget命令获取jdk链接，这是默认不同意，导致下载来的jdk压缩内容错误

2、上传到服务器并解压![在这里插入图片描述][20200113160007162.png]

3、设置环境变量  
/usr/local/java/jdk1.8.0\_171  
![在这里插入图片描述][20200113160026740.png]  
文件末尾加入下面配置

export JAVA_HOME=/usr/local/java/jdk1.8.0_171
    export JRE_HOME=${ JAVA_HOME}/jre
    export CLASSPATH=.:${ JAVA_HOME}/lib:${ JRE_HOME}/lib
    export PATH=${ JAVA_HOME}/bin:$PATH

4、使环境变量生效&测试JDK

**2、安装zookeeper**

1、下载zookeeper  
网址 https://archive.apache.org/dist/zookeeper/zookeeper-3.4.11/  
wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz  
2、解压

3、移动到指定位置并改名为zookeeper

**3、开机启动zookeeper**

1）-复制如下脚本
    #!/bin/bash
    #chkconfig:2345 20 90
    #description:zookeeper
    #processname:zookeeper
    ZK_PATH=/usr/local/zookeeper
    export JAVA_HOME=/usr/local/java/jdk1.8.0_171
    case $1 in
             start) sh  $ZK_PATH/bin/zkServer.sh start;;
             stop)  sh  $ZK_PATH/bin/zkServer.sh stop;;
             status) sh  $ZK_PATH/bin/zkServer.sh status;;
             restart) sh $ZK_PATH/bin/zkServer.sh restart;;
             *)  echo "require start|stop|status|restart"  ;;
    esac

2）-把脚本注册为Service

3）-增加权限  
![在这里插入图片描述][20200113160355910.png]

**4、配置zookeeper**

1、初始化zookeeper配置文件  
拷贝/usr/local/zookeeper/conf/zoo\_sample.cfg  
到同一个目录下改个名字叫zoo.cfg

2、启动zookeeper

## 二、【linux】-安装dubbo-admin管理控制台 ##

**安装Tomcat8（旧版dubbo-admin是war，新版是jar不需要安装Tomcat**）

**1、下载Tomcat8并解压**  
https://tomcat.apache.org/download-80.cgi  
wget http://mirrors.shu.edu.cn/apache/tomcat/tomcat-8/v8.5.32/bin/apache-tomcat-8.5.32.tar.gz  
**2、解压移动到指定位置**  
![在这里插入图片描述][20200113160721866.png]  
**3、开机启动tomcat8**  
![在这里插入图片描述][20200113160724767.png]  
复制如下脚本

#!/bin/bash
    #chkconfig:2345 21 90
    #description:apache-tomcat-8
    #processname:apache-tomcat-8
    CATALANA_HOME=/opt/apache-tomcat-8.5.32
    export JAVA_HOME=/opt/java/jdk1.8.0_171
    case $1 in
    start)
        echo "Starting Tomcat..."  
        $CATALANA_HOME/bin/startup.sh
        ;;
    
    stop)
        echo "Stopping Tomcat..."  
        $CATALANA_HOME/bin/shutdown.sh
        ;;
    
    restart)
        echo "Stopping Tomcat..."  
        $CATALANA_HOME/bin/shutdown.sh
        sleep 2
        echo  
        echo "Starting Tomcat..."  
        $CATALANA_HOME/bin/startup.sh
        ;;
    *)
        echo "Usage: tomcat {start|stop|restart}"  
        ;; esac

4、注册服务&添加权限

5、启动服务&访问tomcat测试  
![在这里插入图片描述][20200113160738547.png]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzMjI5NTQz_size_16_color_FFFFFF_t_70 4]

**安装dubbo-admin**

dubbo本身并不是一个服务软件。它其实就是一个jar包能够帮你的java程序连接到zookeeper，并利用zookeeper消费、提供服务。所以你不用在Linux上启动什么dubbo服务。  
但是为了让用户更好的管理监控众多的dubbo服务，官方提供了一个可视化的监控程序，不过这个监控即使不装也不影响使用。

**1、下载dubbo-admin**

https://github.com/apache/incubator-dubbo-ops  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzMjI5NTQz_size_16_color_FFFFFF_t_70 5]

**2、进入目录，修改dubbo-admin配置**  
修改 src\\main\\resources\\application.properties 指定zookeeper地址  
![在这里插入图片描述][20200113160922776.png]  
**3、打包dubbo-admin**  
mvn clean package -Dmaven.test.skip=true

**4、运行dubbo-admin**  
java -jar dubbo-admin-0.0.1-SNAPSHOT.jar  
默认使用root/root 登陆
