dubbo 2.5.3 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 <<eof export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk.x86_64 export PATH=$JAVA_HOME/bin:$PATH export M2_HOME=/usr/local/apache-maven/ export PATH=$PATH:$M2_HOME/bin eof

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

    <modules>     <module>hessian-lite</module>   <!-- 添加hessian-lite -->     <module>dubbo-common</module>     <module>dubbo-container</module>     <module>dubbo-remoting</module>     ......... </modules> <properties>     .........     <fastjson_version>1.1.39</fastjson_version>   <!-- 修改版本为 1.1.39 -->     ......... </properties>

1. 修改 hessian-lite/pom.xml

    <parent>     <groupId>com.alibaba</groupId>     <artifactId>dubbo-parent</artifactId>     <version>2.5.3</version>   <!-- 修改版本为2.5.3 --> </parent>

2. 修改 dubbo-admin/pom.xml

   webx的依赖改为3.1.6版；

    <dependency>     <groupId>com.alibaba.citrus</groupId>     <artifactId>citrus-webx-all</artifactId>     <version>3.1.6</version> </dependency>

   添加velocity的依赖

    <dependency>     <groupId>org.apache.velocity</groupId>     <artifactId>velocity</artifactId>     <version>1.7</version> </dependency>

   对依赖项dubbo添加exclusion，避免引入旧spring

    <dependency>     <groupId>com.alibaba</groupId>     <artifactId>dubbo</artifactId>     <version>${project.parent.version}</version>     <exclusions>         <exclusion>             <groupId>org.springframework</groupId>             <artifactId>spring</artifactId>         </exclusion>     </exclusions> </dependency>

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

    <!--<dependency>-->     <!--<groupId>org.springframework</groupId>-->     <!--<artifactId>spring</artifactId>--> <!--</dependency>-->

3. 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 <<eof tickTime=2000 initLimit=10 syncLimit=5 dataDir=/var/lib/zookeeper  # 修改ZooKeeper快照存储路径 clientPort=2181 eof

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.gzcd dubbo-demo-provider-2.5.3

修改 conf/dubbo.properties

#dubbo.registry.address=multicast://224.5.6.7:1234dubbo.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.gzcd dubbo-demo-consumer-2.5.3

修改 conf/dubbo.properties

#dubbo.registry.address=multicast://224.5.6.7:1234dubbo.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。
