dubbox 2.8.4 环境搭建

安装Git, JDK 和 Maven

1. 安装jdk, git

    yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel git
   

2. 安装maven

    cd /usr/local/src/
    wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
    tar -zxf apache-maven-3.3.9-bin.tar.gz
    mv apache-maven-3.3.9 /usr/local/
    ln -s /usr/local/apache-maven-3.3.9 /usr/local/apache-maven
   

3. 添加环境变量

    echo >> /root/.bash_profile <

4. 生效环境变量

    . /root/.bash_profile
   

5. 测试java

    [root@openstack_test ~]# java -version
    openjdk version "1.8.0_101"
    OpenJDK Runtime Environment (build 1.8.0_101-b13)
    OpenJDK 64-Bit Server VM (build 25.101-b13, mixed mode)
   

6. 测试maven

    [root@openstack_test ~]# mvn -version
    Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
    Maven home: /usr/local/apache-maven
    Java version: 1.8.0_101, vendor: Oracle Corporation
    Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.101-3.b13.el6_8.x86_64/jre
    Default locale: en_US, platform encoding: UTF-8
    OS name: "linux", version: "2.6.32-573.18.1.el6.x86_64", arch: "amd64", family: "unix"
   

编译dubbo

1. 安装opensesame

    cd /usr/local/src/
    git clone https://github.com/alibaba/opensesame.git
    cd opensesame/
    mvn clean install -Dmaven.test.skip
   

2. 获取dubbo源码

    cd /usr/local/src/
    git clone https://github.com/alibaba/dubbo.git dubbo
    cd /usr/local/src/dubbo
    cp -r hessian-lite/ ../
    git checkout dubbo-2.5.3
    cp -r ../hessian-lite/ ./
   

3. 修改pom.xml

    
        hessian-lite   
        dubbo-common
        dubbo-container
        dubbo-remoting
        .........
    
   
    
        .........
        1.1.39   
        .........
    
   

4. 修改 hessian-lite/pom.xml

    
        com.alibaba
        dubbo-parent
        2.5.3   
    
   

5. 修改 dubbo-admin/pom.xml

   webx的依赖改为3.1.6版；

    
        com.alibaba.citrus
        citrus-webx-all
        3.1.6
    
   

   添加velocity的依赖

    
        org.apache.velocity
        velocity
        1.7
    
   

   对依赖项dubbo添加exclusion，避免引入旧spring

    
        com.alibaba
        dubbo
        ${project.parent.version}
        
            
                org.springframework
                spring
            
        
    
   

   webx已有spring 3以上的依赖，因此注释掉dubbo-admin里面的spring依赖

6. 编译

    mvn clean install -Dmaven.test.skip
   

安装ZooKeeper

1. 安装zookeeper

    cd /usr/local/src
    wget http://apache.fayea.com/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz
    tar -zxf zookeeper-3.4.8.tar.gz
    cp -r zookeeper-3.4.8 /usr/local/
    ln -s /usr/local/zookeeper-3.4.8/ /usr/local/zookeeper
   

2. 修改配置

    cd /usr/local/zookeeper/
    cp conf/zoo_sample.cfg conf/zoo.cfg
   
    echo > conf/zoo.cfg <

3. 启动&测试

   启动 server 端

        bin/zkServer.sh start
   

   启动客户端，尝试创建、查询节点

        bin/zkCli.sh -server localhost:2181
   
   
        [zk: localhost:2181(CONNECTED) 3] create /test 1111
        Created /test
        [zk: localhost:2181(CONNECTED) 4] get /test
        1111
        cZxid = 0x2
        ctime = Thu Sep 01 08:59:24 CST 2016
        mZxid = 0x2
        mtime = Thu Sep 01 08:59:24 CST 2016
        pZxid = 0x2
        cversion = 0
        dataVersion = 0
        aclVersion = 0
        ephemeralOwner = 0x0
        dataLength = 4
        numChildren = 0
   

安装dubbo-admin

1. 安装tomcat

   yum install tomcat6

2. 部署 dubbo-admin 代码

    mkdir /var/lib/tomcat6/webapps/ROOT/
    unzip dubbo-admin/target/dubbo-admin-2.5.3.war -d /var/lib/tomcat6/webapps/ROOT/
   

   确认/var/lib/tomcat6/webapps/ROOT/WEB-INF/dubbo.properties 中ZooKeeper的地址是否正确。本例中，该配置无需修改。 然后就可以启动tomcat了。

    /etc/init.d/tomcat6 restart
   

   可以通过浏览器访问 dubbo-admin。

启动demon

provider

cd /usr/local/src/dubbo/dubbo-demo/dubbo-demo-provider/target/
tar -zxf dubbo-demo-provider-2.5.3-assembly.tar.gz
cd dubbo-demo-provider-2.5.3

修改 conf/dubbo.properties

#dubbo.registry.address=multicast://224.5.6.7:1234
dubbo.registry.address=zookeeper://127.0.0.1:2181

启动provider

bin/start.sh

consumer

cd /usr/local/src/dubbo/dubbo-demo/dubbo-demo-consumer/target/
tar -zxf dubbo-demo-consumer-2.5.3-assembly.tar.gz
cd dubbo-demo-consumer-2.5.3

修改 conf/dubbo.properties

#dubbo.registry.address=multicast://224.5.6.7:1234
dubbo.registry.address=zookeeper://127.0.0.1:2181

启动consumer

bin/start.sh

确认

consumer log

在consumer的日志中可以看到provider的正常回应。

dubbo-admin

在dubbo-admin的 服务治理>>服务 页面也可以看到consumer和provider注册的服务，说明服务正常启动。
