安装java
方法一：手动解压JDK的压缩包，然后设置环境变量
1.在/usr/目录下创建java目录
[root@localhost ~]# mkdir/usr/java
[root@localhost ~]# cd /usr/java
2.下载jdk,然后解压
[root@localhost java]# curl -O http://download.Oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz
[root@localhost java]# tar -zxvf jdk-7u79-linux-x64.tar.gz
3.设置环境变量
[root@localhost java]# vi /etc/profile
在profile中添加如下内容:
#set java environment
JAVA_HOME=/usr/java/jdk1.7.0_79
JRE_HOME=/usr/java/jdk1.7.0_79/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
让修改生效:
[root@localhost java]# source /etc/profile
4.验证JDK有效性
[root@localhost java]# java -version
java version “1.7.0_79”
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
方法二：用yum安装JDK
1.查看yum库中都有哪些jdk版本(暂时只发现了openjdk)
[root@localhost ~]# yum search java|grep jdk
ldapjdk-javadoc.x86_64 : Javadoc for ldapjdk
java-1.6.0-openjdk.x86_64 : OpenJDK Runtime Environment
java-1.6.0-openjdk-demo.x86_64 : OpenJDK Demos

java-1.8.0-openjdk-javadoc.noarch : OpenJDK API Documentation
java-1.8.0-openjdk-src.x86_64 : OpenJDK Source Bundle
ldapjdk.x86_64 : The Mozilla LDAP Java SDK
2.选择版本,进行安装
//选择1.7版本进行安装
[root@localhost ~]# yum install java-1.7.0-openjdk
//安装完之后，默认的安装目录是在: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75.x86_64
3.设置环境变量
[root@localhost ~]# vi /etc/profile
在profile文件中添加如下内容
#set java environment
JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75.x86_64
JRE_HOME=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
让修改生效
[root@localhost java]# source /etc/profile
4.验证(同上一方法)
方法三：用rpm安装JDK
1.下载rpm安装文件
[root@localhost ~]$ curl -O http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.rpm
2.使用rpm命令安装
[root@localhost ~]# rpm -ivh jdk-7u79-linux-x64.rpm
3.设置环境变量
[root@localhost java]# vi /etc/profile
在打开的profile文件中添加如下内容
#set java environment
JAVA_HOME=/usr/java/jdk1.7.0_79
JRE_HOME=/usr/java/jdk1.7.0_79/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
让修改生效
[root@localhost java]# source /etc/profile
4.验证(同上一方法)
注:和yum安装类似，不用设置环境变量就可以运行java命令。rpm安装方式默认会把jdk安装到/usr/java/jdk1.7.0_79，然后通过三层链接，链接到/usr/bin,具体链接如下：
[root@localhost ~]# cd /bin
[root@localhost bin]# ll|grep java
lrwxrwxrwx. 1 root root 25 Mar 28 11:24 jar ->/usr/java/default/bin/jar
lrwxrwxrwx. 1 root root 26 Mar 28 11:24 java -> /usr/java/default/bin/java
lrwxrwxrwx. 1 root root 27 Mar 28 11:24 javac ->/usr/java/default/bin/javac
lrwxrwxrwx. 1 root root 29 Mar 28 11:24 javadoc ->/usr/java/default/bin/javadoc
lrwxrwxrwx. 1 root root 28 Mar 28 11:24 javaws ->/usr/java/default/bin/javaws
lrwxrwxrwx. 1 root root 30 Mar 28 11:24 jcontrol ->/usr/java/default/bin/jcontrol
[root@localhost bin]# cd /usr/java/
[root@localhost java]# ll
total 4
lrwxrwxrwx. 1 root root 16 Mar 28 11:24 default-> /usr/java/latest
drwxr-xr-x. 8 root root 4096 Mar 28 11:24 jdk1.7.0_79
lrwxrwxrwx. 1 root root 21 Mar 28 11:24 latest -> /usr/java/jdk1.7.0_79
方法四：Ubuntu 上使用apt-get安装JDK
1.查看apt库都有哪些jdk版本
root@linuxidc:~# apt-cache search java|grep jdk
default-jdk – Standard Java or Java compatible Development Kit
default-jdk-doc – Standard Java or Java compatible Development Kit (documentation)

2.选择版本进行安装
root@linuxidc:~# apt-get install openjdk-7-jdk
3.设置环境变量
root@linuxidc:~# vi /etc/profile
在打开的profile文件中添加如下内容
#set java environment
JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-amd64
JRE_HOME=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
让修改生效
root@linuxidc:~# source /etc/profile
安装zookeeper
1、创建 /usr/local/services/zookeeper 文件夹：
mkdir -p /usr/local/services/zookeeper
2、进入到 /usr/local/services/zookeeper 目录中：
cd /usr/local/services/zookeeper
3、下载 zookeeper-3.4.9.tar.gz：
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
4、解压缩 zookeeper-3.4.9.tar.gz：
tar -zxvf zookeeper-3.4.9.tar.gz
5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：
cd zookeeper-3.4.9/conf/
6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：
cp zoo_sample.cfg zoo.cfg
7、用 vim 打开 zoo.cfg 文件并修改其内容为如下：
# The number of milliseconds of each tick
# zookeeper 定义的基准时间间隔，单位：毫秒
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# dataDir=/tmp/zookeeper
# 数据文件夹
dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data
# 日志文件夹
dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs
# the port at which the clients will connect
# 客户端访问 zookeeper 的端口号
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to “0” to disable auto purge feature
#autopurge.purgeInterval=1
8、保存并关闭 zoo.cfg 文件:
9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中：
cd ../bin/
10、用 vim 打开 /etc/ 目录下的配置文件 profile：
vim /etc/profile
并在其尾部追加如下内容：
# idea – zookeeper-3.4.9 config start – 2016-09-08
export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH
# idea – zookeeper-3.4.9 config start – 2016-09-08
11、使 /etc/ 目录下的 profile 文件即可生效：
source /etc/profile
12、启动 zookeeper 服务：
zkServer.sh start
如打印如下信息则表明启动成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper … STARTED
13、查询 zookeeper 状态：
zkServer.sh status
14、关闭 zookeeper 服务：
zkServer.sh stop
如打印如下信息则表明成功关闭：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper … STOPPED
15、重启 zookeeper 服务：
zkServer.sh restart
如打印如下信息则表明重启成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper … STOPPED
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper … STARTED
zookeeper集群
#修改配置文件zoo.cfg，如下：
egrep -v “^#|^$” zoo.cfg
tickTime=2000 initLimit=10 syncLimit=5 dataLogDir=/opt/zookeeper/logs dataDir=/opt/zookeeper/data clientPort=2181 autopurge.snapRetainCount=500 autopurge.purgeInterval=24 server.1= 192.168.1.148:2888:3888 server.2= 192.168.1.149:2888:3888 server.3= 192.168.1.150:2888:3888
#创建相关目录，三台节点都需要
mkdir -p /tmp/zookeeper/{logs,data}
#其余zookeeper节点安装完成之后，同步配置文件zoo.cfg。
cd /tmp/zookeeper/
创建ServerID标识
除了修改zoo.cfg配置文件外,zookeeper集群模式下还要配置一个myid文件,这个文件需要放在dataDir目录下。
这个文件里面有一个数据就是A的值（该A就是zoo.cfg文件中server.A=B:C:D中的A）,在zoo.cfg文件中配置的dataDir路径中创建myid文件。
#在192.168.1.148服务器上面创建myid文件，并设置值为1，同时与zoo.cfg文件里面的server.1保持一致，如下
echo “1” > /tmp/zookeeper//myid
#在192.168.1.149服务器上面创建myid文件，并设置值为1，同时与zoo.cfg文件里面的server.2保持一致，如下
echo “2” > /tmp/zookeeper//myid
#在192.168.1.150服务器上面创建myid文件，并设置值为1，同时与zoo.cfg文件里面的server.3保持一致，如下
echo “3” > /tmp/zookeeper//myid
到此，相关配置已完成
启动zk,如果报错，检查zoo.cfg配置文件和iptbale防火墙
或者
mkdir -p /usr/local/services/zookeeper/zookeeper-3.4.9/data
cd /usr/local/services/zookeeper/zookeeper-3.4.9/data
echo “2” > /usr/local/services/zookeeper/zookeeper-3.4.9/data/myid
重启zk
注：官网上是maven项目，这里把它都变成了web项,官网上用maven只创建了一个maven的接口，然后生产者，消费者去依赖这个接口，这里是在消费者和生产者中都创建了一个相同的接口
motan 生产者配置
已mian方法启动 和 web 方式启动
创建接口
package com.business.user.service;
import java.util.List;
import com.business.user.domain.User;
/
* @ClassName: UserService
* @Description: User服务接口
*
*/
public interface UserServices {
/
* 批量删除
* @param ids 要删除的UserID集合
* @return 删除成功的记录生活
*/
public String hello(String name);
}
实现类UserServiceImpls实现接口，如下，其中，MotanService是motan的服务注册注解
package com.business.user.service.impl;
import com.business.user.service.UserServices;
import com.weibo.api.motan.config.springsupport.annotation.MotanService;
/
* @ClassName: UserServiceImpl
* @Description: User服务实现类
*
*/
@MotanService
public class UserServiceImpls implements UserServices {
@Override
public String hello(String name) {
return “hello,”+name;
}
}
如果没有controller，不需要启动tomcat服务，可以直接使用main函数启动，类如下：
public class Main { public static void main(String[] args) { @SuppressWarnings(“unused”) ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] {“classpath*:spring.xml”}); MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true); System.out.println(“server start…”); } }
配置web.xml文件 (已main方法启动不需要配置web)
xsi:schemaLocation=”http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd”
id=”WebApp_ID” version=”3.0″>
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encodingFilter
/*
spring_mvc_dispatcher
org.springframework.web.servlet.DispatcherServlet
1
spring_mvc_dispatcher
/
在src/main/resources中添加spring.xml
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xmlns:context=”http://www.springframework.org/schema/context”
xmlns:motan=”http://api.weibo.com/schema/motan”
xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://api.weibo.com/schema/motan http://api.weibo.com/schema/motan.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd”>
maxServerConnection=”80000″ maxContentLength=””
maxWorkerThread=”800″ minWorkerThread=”20″/>
group=”lyncc-motan-demo-rpc” accessLog=”true” shareChannel=”true” module=”motan-demo-rpc”
application=”myMotanDemo” registry=”registry” id=”serviceBasicConfig”/>
为了实现优雅的起启服务，需要定义一个ServletContextListener来启动或关闭服务MotanSwitcherUtil，经测试，如果不配置的话，通过servlet发布的服务将无法使用
package motan.demo.server.server.listener;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import com.weibo.api.motan.common.MotanConstants;
import com.weibo.api.motan.util.MotanSwitcherUtil;
public class MotanServletContextListener implements ServletContextListener {
public void contextDestroyed(ServletContextEvent arg0) {
}
@Override
public void contextInitialized(ServletContextEvent event) {
System.out.println(“”);
MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
}
}
在src/main/resources目录中添加spring-mvc.xml配置文件(如果项目是 spingmvc 需要访问controller 则配置，否则可以不配)
xmlns:context=”http://www.springframework.org/schema/context”
xmlns:mvc=”http://www.springframework.org/schema/mvc”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xmlns:util=”http://www.springframework.org/schema/util”
xsi:schemaLocation=”http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util.xsd “>
motan 消费者配置
已mian方法启动 和 web 方式启动
创建接口（要和生产者提供的接口相同，包名也需要相同）
package com.business.user.service;
import java.util.List;
import com.business.user.domain.User;
/
* @ClassName: UserService
* @Description: User服务接口
*
*/
public interface UserServices {
/
* 批量删除
* @param ids 要删除的UserID集合
* @return 删除成功的记录生活
*/
public String hello(String name);
}
定义一个Service，引用motan服务
package com.business.user.service.impl;
import org.springframework.stereotype.Service;
import com.business.user.service.UserServices;
import com.weibo.api.motan.config.springsupport.annotation.MotanReferer;
/
* @ClassName: UserServiceImpl
* @Description: User服务实现类
*
*/
@Service
public class UserServiceImpls {
@MotanReferer
private UserServices userServices;
public String say(String name){
System.out.println(“motan”+”9999″+”ooooooo”);
System.out.println(name);
String result=userServices.hello(“woaini”);
System.out.println(result);
return result;
}
}
定义controller，引用Service
@Autowired
private UserServiceImpls userServiceImpls;
/
* 批量删除记录
*/
public void delete() {
String msg = “”;
if (ids != null && ids.length > 0){
System.out.println(userServiceImpls.say(“binibin”));
int s = userService.deleteByIds(ids);
msg = “删除成功” + s + “条记录”;
} else {
msg = “请选择要删除的记录!”;
}
JSONOuter().writeSuccessMsg(getOut(), msg);
}
如果这个项目也没有controller，则也可以直接使用main函数启动， 进行调用测试，内容如下
package com;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.business.user.service.UserServices;
public class ClientStart {
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext(“classpath:spring/spring-server.xml”);
UserServices service = (UserServices) ctx.getBean(“remoteService”);
for(int i = 0;i< 50;i++){
System.out.println(service.hello(“motan”));
}
}
}
实现优雅的起启服务
public class MotanServletContextListener implements ServletContextListener {
public void contextDestroyed(ServletContextEvent arg0) {
}
@Override
public void contextInitialized(ServletContextEvent event) {
System.out.println(“”);
MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
}
web.xml配置文件与motan-server项目相同
集成马场 web.xml
