环境：
OS版本：CentOS 7.2
jdk "1.7.0_79"
Zookeeper version: 3.3.6-1366786
Dubbo版本：2.5.3
Apache Tomcat 7.0.69
测试环境为防止干扰，可检查并关闭linux安全设置：
# getenforce
Enforcing
# setenforce 0
编辑selinux，修改如下内容：
SELINUX=enforcing
vi /etc/sysconfig/selinux
SELINUX=disabled
#systemctl stop firewalld.service
#systemctl disable firewalld.service
1.设置主机名：
[root@localhost ~]# hostnamectl set-hostname test-dubbosvr
2.编辑hosts文件，添加记录：
ip hostname
# vi /etc/hosts
3.安装JDK:
下载jdk-7u79-linux-x64.tar.gz至/usr/local/src目录
建立安装目录：
# mkdir -pv /usr/local/java
mkdir: created directory ‘/usr/local/java’
解压jdk-7u79-linux-x64.tar.gz
[root@test-dubbosvr src]# tar zxf jdk-7u79-linux-x64.tar.gz
[root@test-dubbosvr src]# mv jdk1.7.0_79 /usr/local/java
检测当前java版本：
# java -version
-bash: java: command not found
安装jdk:
# alternatives --install /usr/bin/java java /usr/local/java/jdk1.7.0_79/bin/java 2
# alternatives --config java
There is 1 program that provides 'java'.
Selection Command
-----------------------------------------------
*+ 1 /usr/local/java/jdk1.7.0_79/bin/java
Enter to keep the current selection[+], or type selection number:Please Enter
# alternatives --install /usr/bin/jar jar /usr/local/java/jdk1.7.0_79/bin/jar 2
# alternatives --install /usr/bin/javac javac /usr/local/java/jdk1.7.0_79/bin/javac 2
检测java版本：
# 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)
配置环境变量：
# vi /etc/profile
添加内容：
export JAVA_HOME=/usr/local/java/jdk1.7.0_79
export JRE_HOME=/usr/local/java/jdk1.7.0_79/jre
export PATH=$PATH:/usr/local/java/jdk1.7.0_79/bin:/usr/local/java/jdk1.7.0_79/jre/bin
使环境变量生效：source /etc/profile
4.安装zookeeper（三节点伪分布式集群）：
下载zookeeper-3.3.6.tar.gz至/usr/local/src目录
解压zookeeper-3.3.6.tar.gz
# tar zxf zookeeper-3.3.6.tar.gz
建立安装目录：
# mkdir -pv /usr/local/zookeeper/{server01,server02,server03}
mkdir: created directory ‘/usr/local/zookeeper’
mkdir: created directory ‘/usr/local/zookeeper/server01’
mkdir: created directory ‘/usr/local/zookeeper/server02’
mkdir: created directory ‘/usr/local/zookeeper/server03’
建立logs，data目录：
# mkdir -pv /usr/local/zookeeper/server01/{logs,data}
mkdir: created directory ‘/usr/local/zookeeper/server01/logs’
mkdir: created directory ‘/usr/local/zookeeper/server01/data’
# mkdir -pv /usr/local/zookeeper/server02/{logs,data}
mkdir: created directory ‘/usr/local/zookeeper/server02/logs’
mkdir: created directory ‘/usr/local/zookeeper/server02/data’
# mkdir -pv /usr/local/zookeeper/server03/{logs,data}
mkdir: created directory ‘/usr/local/zookeeper/server03/logs’
mkdir: created directory ‘/usr/local/zookeeper/server03/data’
# cd /usr/local/src/zookeeper-3.3.6/conf
# cp zoo_sample.cfg zoo.cfg
编辑zoo.cfg，内容如下：
# The number of milliseconds of each tick
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.

server.2=192.168.195.136:2889:3889
server.3=192.168.195.136:2890:3890
复制/usr/local/src/zookeeper-3.3.6至/usr/local/zookeeper/server01目录下：
# cp -ar /usr/local/src/zookeeper-3.3.6 /usr/local/zookeeper/server01
# echo 1 > /usr/local/zookeeper/server01/data/myid
编辑/usr/local/src/zookeeper-3.3.6/conf/zoo.cfg，内容如下：

server.2=192.168.195.136:2889:3889
server.3=192.168.195.136:2890:3890
复制/usr/local/src/zookeeper-3.3.6至/usr/local/zookeeper/server02目录下：
# cp -ar /usr/local/src/zookeeper-3.3.6 /usr/local/zookeeper/server02
# echo 2 > /usr/local/zookeeper/server02/data/myid
编辑/usr/local/src/zookeeper-3.3.6/conf/zoo.cfg，内容如下：

复制/usr/local/src/zookeeper-3.3.6至/usr/local/zookeeper/server03目录下：
# cp -ar /usr/local/src/zookeeper-3.3.6 /usr/local/zookeeper/server03
# echo 3 > /usr/local/zookeeper/server03/data/myid
启动zookeeper（zkServer.sh start）:
# /usr/local/zookeeper/server01/zookeeper-3.3.6/bin/zkServer.sh start

5.安装dubbo-monitor
下载dubbo-monitor-simple-2.5.3-assembly.tar.gz至/usr/local/src目录
建立安装目录：
# mkdir -pv /usr/local/dubbo
mkdir: created directory ‘/usr/local/dubbo’
解压dubbo-monitor-simple-2.5.3-assembly.tar.gz
# tar zxf dubbo-monitor-simple-2.5.3-assembly.tar.gz
复制/usr/local/src/dubbo-monitor-simple-2.5.3至/usr/local/dubbo目录下：
# cp -ar /usr/local/src/dubbo-monitor-simple-2.5.3 /usr/local/dubbo
编辑dubbo.properties：
注释如下内容：
dubbo.registry.address=multicast://224.5.6.7:1234
修改如下内容：
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.jetty.port=8080
dubbo.jetty.directory=${user.home}/monitor
dubbo.statistics.directory=${user.home}/monitor/statistics
dubbo.log4j.file=logs/dubbo-monitor-simple.log
#cd /usr/local/dubbo/dubbo-monitor-simple-2.5.3/conf

dubbo.jetty.directory=/usr/local/dubbo/dubbo-monitor-simple-2.5.3/monitor
dubbo.charts.directory=${dubbo.jetty.directory}/charts
dubbo.statistics.directory=${dubbo.jetty.directory}/statistics
dubbo.log4j.file=/usr/local/dubbo/dubbo-monitor-simple-2.5.3/logs/dubbo-monitor-simple.log
dubbo.log4j.level=WARN
创建目录monitor,logs：
# mkdir -pv /usr/local/dubbo/dubbo-monitor-simple-2.5.3/{monitor,logs}
mkdir: created directory ‘/usr/local/dubbo/dubbo-monitor-simple-2.5.3/monitor’
mkdir: created directory ‘/usr/local/dubbo/dubbo-monitor-simple-2.5.3/logs’
创建目录charts,statistics：
# mkdir -pv /usr/local/dubbo/dubbo-monitor-simple-2.5.3/monitor/{charts,statistics}
mkdir: created directory ‘/usr/local/dubbo/dubbo-monitor-simple-2.5.3/monitor/charts’
mkdir: created directory ‘/usr/local/dubbo/dubbo-monitor-simple-2.5.3/monitor/statistics’
启动dubbo:
# /usr/local/dubbo/dubbo-monitor-simple-2.5.3/bin/start.sh
Starting the simple-monitor .......OK!
PID: 16835
STDOUT: /usr/local/dubbo/dubbo-monitor-simple-2.5.3/logs/stdout.log
检查端口状态：
# netstat -ano | grep 7070
tcp 0 0 0.0.0.0:7070 0.0.0.0:* LISTEN off (0.00/0/0)
# netstat -ano | grep 8088

6.安装tomcat，并安装配置dubbo-admin
下载apache-tomcat-7.0.69.tar.gz至/usr/local/src目录
解压apache-tomcat-7.0.69.tar.gz
# tar zxf apache-tomcat-7.0.69.tar.gz
建立安装目录/usr/local/dubbo/dubbo-admin-tomcat：
# mkdir -pv /usr/local/dubbo/dubbo-admin-tomcat
mkdir: created directory ‘/usr/local/dubbo/dubbo-admin-tomcat’
复制/usr/local/src/apache-tomcat-7.0.69目录下所有文件至/usr/local/dubbo/dubbo-admin-tomcat目录下：
（注：不包含/usr/local/src/apache-tomcat-7.0.69目录本身）
# cp -ar /usr/local/src/apache-tomcat-7.0.69/. /usr/local/dubbo/dubbo-admin-tomcat
删除tomcat自带的webapps/ROOT目录：
# rm -rf /usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT
下载dubbo-admin-2.5.3.war至/usr/local/src目录
解压dubbo-admin-2.5.3.war至/usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT目录:
# unzip /usr/local/src/dubbo-admin-2.5.3.war -d /usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT
编辑/usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT/WEB-INF/dubbo.properties文件：
修改如下内容：
dubbo.registry.address=zookeeper://127.0.0.1:2181?backup=127.0.0.1:2182,127.0.0.1:2183
vi /usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT/WEB-INF/dubbo.properties
dubbo.registry.address=zookeeper://192.168.195.136:2181?backup=192.168.195.136:2182,192.168.195.136:2183
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest
启动tomcat：
# /usr/local/dubbo/dubbo-admin-tomcat/bin/startup.sh
Using CATALINA_BASE: /usr/local/dubbo/dubbo-admin-tomcat
Using CATALINA_HOME: /usr/local/dubbo/dubbo-admin-tomcat
Using CATALINA_TMPDIR: /usr/local/dubbo/dubbo-admin-tomcat/temp
Using JRE_HOME: /usr/local/java/jdk1.7.0_79/jre
Using CLASSPATH: /usr/local/dubbo/dubbo-admin-tomcat/bin/bootstrap.jar:/usr/local/dubbo/dubbo-admin-tomcat/bin/tomcat-juli.jar

7.访问dubbo
用户名：root
密码：root
8.重启机器后，需要先启动zookeeper，然后启动dubbo-monitor，最后启动dubbo-admin（即tomcat）。
