dubbo学习笔记(十五) dubbox笔记

需要2核4G的机器，内存稍大才可以编译成功

git clone https://github.com/alibaba/dubbo.git
mvn clean install -Dmaven.test.skip
export MAVEN_OPTS="-Xms512m -Xmx1024m"

1、启动zk
cd /opt/zk/conf
cp zoo_sample.cfg zoo.cfg
cd ../bin
./zkServer.sh start

2、启动admin
cd ~/dubbo/dubbo-admin
target里面的war包丢到tomcat的webapps目录下面去
然后bin/statup.sh
启动之后8080端口即可以向外服务
http://xxxx:8080/dubbo-admin/
会提示你输入用户名和密码，root,root......


3、启动monitor
cd ~/dubbo/dubbo-simple/dubbo-monitor-simple/target
./start.sh
vi dubbo.properties
   - edit: dubbo.registry.adddress=dubbo://127.0.0.1:9090
cd ../bin
./restart.sh

=============================================================
dubbox

1、项目地址
https://github.com/dangdangdotcom/dubbox.git

-------------------------------------------

2、编译
git clone https://github.com/dangdangdotcom/dubbox.git

cd dubbox/
export MAVEN_OPTS="-Xms512m -Xmx1024m"
mvn clean install -Dmaven.test.skip


-------------------------------------------

3、安装java环境

安装JAVA----CENTOS 6.6，64位系统，JDK 7

包是使用scp上传到目标机器的

tar zxvf jdk.tar.gz
mv jdk/ /opt/

sudo update-alternatives --install /usr/bin/java java /opt/jdk/bin/java 300
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk/bin/javac 300
sudo update-alternatives --install /usr/bin/jar jar /opt/jdk/bin/jar 300
sudo update-alternatives --config java

vim /etc/profile
export JAVA_HOME=/opt/jdk
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

验证
java -version

java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

-------------------------------------------

4、安装zookeeper

【参考资料1：http://www.iyunv.com/thread-18609-1-1.html】
【参考资料2：http://my.oschina.net/u/1866130/blog/287363】

http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/
zk有依赖于jdk

wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
tar zxvf zookeeper-3.4.6.tar.gz
mv zookeeper-3.4.6 /opt/zk
mkdir tools
mv jdk.tar.gz zookeeper-3.4.6.tar.gz tools/

如果想把一个文件1的内容清空， 文件大小变成0， 又不删除这个文件，可以用：
cat /dev/null > 文件1

单机启用：
cd /opt/zk/conf
cp zoo_sample.cfg zoo.cfg
cd ../bin
./zkServer.sh start

配置集群模式：三台机器上分别运行（一定要确保ping三个ip之间是正确的，FQDN的问题）

echo '192.168.60.10 zk1' >>/etc/hosts
echo '192.168.60.11 zk2' >>/etc/hosts
echo '192.168.60.12 zk3' >>/etc/hosts

cp /opt/zk/conf/zoo_sample.cfg /opt/zk/conf/zoo.cfg
echo 'server.1=zk1:2888:3888' >> /opt/zk/conf/zoo.cfg
echo 'server.2=zk2:2888:3888' >> /opt/zk/conf/zoo.cfg
echo 'server.3=zk3:2888:3888' >> /opt/zk/conf/zoo.cfg

mkdir /opt/zk/storage
sed -i "s/\/tmp\/zookeeper/\/opt\/zk\/storage/g" /opt/zk/conf/zoo.cfg

三台机器上分别执行：
echo "1" > /opt/zk/storage/myid
echo "2" > /opt/zk/storage/myid
echo "3" > /opt/zk/storage/myid

三台机器上分别运行：
/opt/zk/bin/zkServer.sh start

然后检查各个主机的状态是：
/opt/zk/bin/zkServer.sh status

=======================================================================

5、安装maven
wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.2.5/binaries/apache-maven-3.2.5-bin.tar.gz

tar zxvf apache-maven-3.2.5-bin.tar.gz
mv apache-maven-3.2.5 /opt/maven

vim /etc/profile
export M2_HOME=/opt/maven
export M2=$M2_HOME/bin
export PATH=$M2:$PATH


=======================================================================

6、运行dubbox

6.1、启动zk
cd /opt/zk/conf
cp zoo_sample.cfg zoo.cfg
cd ../bin
./zkServer.sh start

6.2、启动admin
cd ~/dubbo/dubbo-admin
target里面的war包丢到tomcat的webapps目录下面去
然后bin/statup.sh
启动之后8080端口即可以向外服务
http://xxxx:8080/dubbo-admin/
会提示你输入用户名和密码，root,root......


6.3、启动monitor
cd ~/dubbo/dubbo-simple/dubbo-monitor-simple/target
./start.sh
vi dubbo.properties
   - edit: dubbo.registry.adddress=dubbo://127.0.0.1:9090
cd ../bin
./restart.sh


-------------------------------------
-------------------------------------

6.4 运行demo
首先保证zk启动成功了，得注意/tmp下有没有脏数据
然后进入dubbo-demo文件夹

-------------------------------------
6.4.1 运行消费方

#pwd 消费者方
/root/dubbox/dubbo-demo/dubbo-demo-consumer/target

#解压消费方：
tar zxvf dubbo-demo-consumer-2.8.4-SNAPSHOT-assembly.tar.gz

[root@200248 target]# cd dubbo-demo-consumer-2.8.4-SNAPSHOT
[root@200248 dubbo-demo-consumer-2.8.4-SNAPSHOT]# ls
bin conf lib
[root@200248 dubbo-demo-consumer-2.8.4-SNAPSHOT]# ll
总用量 12
drwxrwxrwx. 2 root root 4096 3月 17 13:45 bin
drwxrwxrwx. 2 root root 4096 3月 17 13:26 conf
drwxr-xr-x. 2 root root 4096 3月 17 13:52 lib

#修改配置使用zk注册
/root/dubbox/dubbo-demo/dubbo-demo-consumer/target/dubbo-demo-consumer-2.8.4-SNAPSHOT/conf

vim dubbo.properties

#################
dubbo.container=log4j,spring
dubbo.application.name=demo-consumer
dubbo.application.owner=
dubbo.registry.address=multicast://224.5.6.7:1234
#dubbo.registry.address=zookeeper://127.0.0.1:2181
#dubbo.registry.address=redis://127.0.0.1:6379
#dubbo.registry.address=dubbo://127.0.0.1:9090
dubbo.monitor.protocol=registry
dubbo.log4j.file=logs/dubbo-demo-consumer.log
dubbo.log4j.level=WARN
#################
注销掉2181那行

#启动消费方
/root/dubbox/dubbo-demo/dubbo-demo-consumer/target/dubbo-demo-consumer-2.8.4-SNAPSHOT/bin
./start.sh
就启动了消费方



-------------------------------------

6.4.2 运行服务方

【安装tomcat】
wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.59/bin/apache-tomcat-7.0.59.tar.gz
tar zxvf apache-tomcat-7.0.59.tar.gz

【拷贝war包】
cp dubbo-demo-provider-2.8.4-SNAPSHOT.war apache-tomcat-7.0.59/webapps/

【启动tomcat】
/root/dubbox/dubbo-demo/dubbo-demo-provider/target/apache-tomcat-7.0.59/bin
./startup.sh

【看logs是否有报错】

-------------------------------------

6.4.3 运行顺序---

反了，应该先服务方后消费方的

-------------------------------------

6.4.4 zk目录结构

ls /dubbo
[com.alibaba.dubbo.demo.user.facade.AnotherUserRestService, com.alibaba.dubbo.demo.user.facade.UserRestService, com.alibaba.dubbo.demo.bid.BidService, com.alibaba.dubbo.monitor.MonitorService, com.alibaba.dubbo.demo.user.UserService]

ls /dubbo/com.alibaba.dubbo.demo.user.facade.AnotherUserRestService/configurators
[]


-------------------------------------
6.4.5 运行一个简单监控

/root/dubbox/dubbo-simple/dubbo-monitor-simple/target

#解压
tar zxvf dubbo-monitor-simple-2.8.4-SNAPSHOT-assembly.tar.gz

cd /root/dubbox/dubbo-simple/dubbo-monitor-simple/target/dubbo-monitor-simple-2.8.4-SNAPSHOT

#进入conf目录
dubbo.container=log4j,spring,registry,jetty
dubbo.application.name=simple-monitor
dubbo.application.owner=
#dubbo.registry.address=multicast://224.5.6.7:1234
dubbo.registry.address=zookeeper://127.0.0.1:2181
#dubbo.registry.address=redis://127.0.0.1:6379
#dubbo.registry.address=dubbo://127.0.0.1:9090
dubbo.protocol.port=7070
dubbo.jetty.port=8080
dubbo.jetty.directory=${user.home}/monitor
dubbo.charts.directory=${dubbo.jetty.directory}/charts
dubbo.statistics.directory=${user.home}/monitor/statistics
dubbo.log4j.file=logs/dubbo-monitor-simple.log
dubbo.log4j.level=WARN

￥￥￥￥￥￥￥￥￥￥￥￥￥

打开zk开关，最后监听的端口是？8080


cd ~/dubbo/dubbo-simple/dubbo-monitor-simple/target
./start.sh
vi dubbo.properties
   - edit: dubbo.registry.adddress=dubbo://127.0.0.1:9019
cd ../bin
./restart.sh

----------------------------------------------------
之后
zk下/dubbo/目录下会多一个目录
com.alibaba.dubbo.monitor.MonitorService

ls /dubbo/com.alibaba.dubbo.monitor.MonitorService
[consumers, routers, providers, configurators]
[zk: localhost:2181(CONNECTED) 18]
