zookeeper3.4.5集群部署及dubbo2.5.3入门例子

一、基础信息配置

1、1 虚拟机硬件配置

 

1、2虚拟机软件配置(准备三台机器)

1、2、1 公共配置

 

[root@zk11 ~]# cat /etc/redhat-release 
CentOS release 6.7 (Final)
[root@zk11 ~]# uname -r
2.6.32-573.el6.x86_64
[root@zk11 ~]# cat /etc/sysconfig/i18n
LANG="en_US.UTF-8"

 

1、2 、2三台机器各自配置

1、2、2、1 ZK11机器

 

 

[root@zk11 ~]# hostname
zk11
[root@zk11 ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=zk11
 
#对外提供IP，这里简称外网IP
[root@zk11 ~]# ifconfig eth0|awk -F '[ :]+' 'NR==2{print $4}'
10.0.0.11
 
#对内提供IP，这里简称内网IP
[root@zk11 ~]# ifconfig eth1|awk -F '[ :]+' 'NR==2{print$4}'
172.16.1.11

 

1、2、2、2 ZK12机器

 

 [root@zk12~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=zk12
[root@zk12 ~]# ifconfig eth0|awk -F '[ :]+' 'NR==2{print $4}'
10.0.0.12
[root@zk12 ~]# ifconfig eth1|awk -F '[ :]+' 'NR==2{print$4}' 
172.16.1.12

 

1、2、2、3 ZK13机器

 

[root@zk13 ~]# hostname
zk13
[root@zk13 ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=zk13
[root@zk13 ~]# ifconfig eth0|awk -F '[ :]+' 'NR==2{print$4}' 
10.0.0.13
[root@zk13 ~]# ifconfig eth1|awk -F '[ :]+' 'NR==2{print$4}' 
172.16.1.13

 

1、2、3建立安装部署文件目录

 

#各个安装包上传目录
[root@zk11 ~]# mkdir -p /home/llyweb/tools/
 
#各个安装包软链接目录
[root@zk11 ~]# mkdir /application/

 

二、Zookeeper3.4.5部署

2、1三台机器共同配置

2、1、1上传JDK以及zookeeper

 

[root@zk11 tools]# pwd
/home/llyweb/tools
[root@zk11 tools]# ll jdk-7u79-linux-x64.tar.gzzookeeper-3.4.5.tar.gz
-rw-r--r-- 1 root root 153512879 Apr 18 15:22jdk-7u79-linux-x64.tar.gz
-rw-r--r-- 1 root root 16402010 Apr 18 15:19 zookeeper-3.4.5.tar.gz

 

2、1、2安装JDK及配置环境变量

 

参考“java的maven工程部署到linux的前半部分，

http://ylcodes01.blog.51cto.com/5607366/1774050”

 

2、1、3三台机器共同操作配置

 

[root@zk11 tools]# pwd
/home/llyweb/tools
[root@zk11 tools]# tar -zxf zookeeper-3.4.5.tar.gz
[root@zk11 tools]# ls -ld zookeeper-3.4.5
drwxr-xr-x 11 root root 4096 Apr 18 15:33 zookeeper-3.4.5
[root@zk11 tools]# ln -s/home/llyweb/tools/zookeeper-3.4.5/ /application/zookeeper
[root@zk11 zookeeper]# mkdir data
[root@zk11 zookeeper]# ls -ld/application/zookeeper/data/
drwxr-xr-x 3 root root 4096 Apr 18 17:42/application/zookeeper/data/
[root@zk11 conf]# pwd
/application/zookeeper/conf
[root@zk11 conf]# cp zoo_sample.cfg zoo.cfg
#编辑zoo.cfg文件
#修改dataDir为
dataDir=/application/zookeeper/data
#最下面加入
server.1=10.0.0.11:2888:3888
server.2=10.0.0.12:2888:3888
server.3=10.0.0.13:2888:3888

 

2、2 各个机器配置

2、2、1 ZK11-10.0.0.11配置

 

[root@zk11 zookeeper]# echo "1" >/application/zookeeper/data/myid

 

2、2、2 ZK12-10.0.0.12配置

 

[root@zk12 tools]# echo "2" >/application/zookeeper/data/myid

 

2、2、3 ZK13-10.0.0.13配置

 

[root@zk13 ~]# echo "3" >/application/zookeeper/data/myid

 

2、2、4注意事项

 

上述三者机器的写入/application/zookeeper/data/myid中的数字1、2、3一定要对应
“2、1、3三台机器共同操作配置”中的
server.1=10.0.0.11:2888:3888
server.2=10.0.0.12:2888:3888
server.3=10.0.0.13:2888:3888

 

2、3测试部署

2、3、1分别启动三台机器

 

[root@zk11 zookeeper]# /bin/sh/application/zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /application/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
 
[root@zk12 tools]# /bin/sh /application/zookeeper/bin/zkServer.shstart
JMX enabled by default
Using config: /application/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
 
[root@zk13 ~]# /bin/sh/application/zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /application/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

 

 

2、3、2检查三台机器状态

 

#zookeeper推荐奇数型集群配置，下述三者机器的主节点不一定是哪台，在执行下述命令的时候可能会报错，猜测是还没检测好节点，稍等一会即可看到下述成功标识。

 

[root@zk11 zookeeper]# /bin/sh/application/zookeeper/bin/zkServer.sh status

2、3、3停止三台机器(仅测试)

三、DUBBO2.5.3部署

 

3、1上传Tomcat和dubbo-admin.war

3、2安装部署dubbo

3、2、1部署Tomcat

参考“java的maven工程部署到linux的前半部分，

http://ylcodes01.blog.51cto.com/5607366/1774050”

 

3、1、2只在ZK11机器部署dubbo

3、1、2、1dubbo-admin.war说明

 

dubbo-admin.war可在下载dubbo源码后，通过maven编译生成对应版本的dubbo-admin.war，也可搜索出已打包好的dubbo-admin.war。

 

3、1、2、2部署dubbo-admin.war

 

[root@zk11 tools]# rm -rf/application/tomcat/webapps/ROOT/*
[root@zk11 tools]# unzip dubbo-admin.war -d/application/tomcat/webapps/ROOT/
[root@zk11 WEB-INF]# pwd
/application/tomcat/webapps/ROOT/WEB-INF
[root@zk11 WEB-INF]# cp dubbo.propertiesdubbo.properties.ori
[root@zk11 WEB-INF]# cat dubbo.properties
dubbo.registry.address=zookeeper://10.0.0.11:2181?backup=10.0.0.12:2181,10.0.0.13:2181
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest

 

3、1、2、3启动Tomcat并访问dubbo

 

#在启动此Tomcat之前记得在/etc/hosts的最后加入127.0.0.1 zk11
[root@zk11 application]# /bin/sh/application/tomcat/bin/startup.sh >/dev/null 2>&1
[root@zk11 application]# ps -ef|grep java|grep -v grep

四、Java整合DUBBO

4、1服务端test1和客户端test2目录结构

 

 

4、2服务端test1代码配置

4、2、1Java代码部分

4、4运行服务

 

#记得一定先要clean install服务端Test1，再clean install客户端Test1

#先运行Test1服务端Provider，再运行Test2客户端Consumer

#结果为

Hello tom
