1、2虚拟机软件配置(准备三台机器)
1、2、1 公共配置
# cat /etc/redhat-release
CentOS release 6.7 (Final)
# uname -r
2.6.32-573.el6.x86_64
# 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
# hostname
zk11
# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=zk11
#对外提供IP，这里简称外网IP
# ifconfig eth0|awk -F '[ :]+' 'NR==2{print $4}'
10.0.0.11
#对内提供IP，这里简称内网IP
# ifconfig eth1|awk -F '[ :]+' 'NR==2{print$4}'
172.16.1.11
1、2、2、2 ZK12机器
# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=zk12
# ifconfig eth0|awk -F '[ :]+' 'NR==2{print $4}'
10.0.0.12
# ifconfig eth1|awk -F '[ :]+' 'NR==2{print$4}'
172.16.1.12
1、2、2、3 ZK13机器
# hostname
zk13
# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=zk13
# ifconfig eth0|awk -F '[ :]+' 'NR==2{print$4}'
10.0.0.13
# 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
# mkdir -p /home/llyweb/tools/
#各个安装包软链接目录
# 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
# pwd
/home/llyweb/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.运维网.com/5607366/1774050”
2、1、3三台机器共同操作配置
# pwd
/home/llyweb/tools
# tar -zxf zookeeper-3.4.5.tar.gz
# ls -ld zookeeper-3.4.5
drwxr-xr-x 11 root root 4096 Apr 18 15:33 zookeeper-3.4.5
# ln -s/home/llyweb/tools/zookeeper-3.4.5/ /application/zookeeper
# mkdir data
# ls -ld/application/zookeeper/data/
drwxr-xr-x 3 root root 4096 Apr 18 17:42/application/zookeeper/data/
# pwd
/application/zookeeper/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
# echo "1" >/application/zookeeper/data/myid
2、2、2 ZK12-10.0.0.12配置
# echo "2" >/application/zookeeper/data/myid
2、2、3 ZK13-10.0.0.13配置
# 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
# /bin/sh/application/zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /application/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
# /bin/sh /application/zookeeper/bin/zkServer.shstart
JMX enabled by default
Using config: /application/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
# /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。

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.运维网.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
# rm -rf/application/tomcat/webapps/ROOT/*
# unzip dubbo-admin.war -d/application/tomcat/webapps/ROOT/
# pwd
/application/tomcat/webapps/ROOT/WEB-INF
# cp dubbo.propertiesdubbo.properties.ori
# 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
# /bin/sh/application/tomcat/bin/startup.sh >/dev/null 2>&1
# ps -ef|grep java|grep -v grep
