dubbo搭建

原創 betterit360 2019-02-23 00:02

環境：

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

 

測試環境爲防止干擾，可檢查並關閉linux安全設置：

# getenforce

Enforcing

# setenforce 0

編輯selinux，修改如下內容：

SELINUX=enforcing

vi /etc/sysconfig/selinux

SELINUX=disabled

 

#systemctl stop firewalld.service

#systemctl disable firewalld.service

 

1.設置主機名：

[root@localhost ~]# hostnamectl set-hostname test-dubbosvr

 

2.編輯hosts文件，添加記錄：

ip hostname

# vi /etc/hosts

 

3.安裝JDK:

下載jdk-7u79-linux-x64.tar.gz至/usr/local/src目錄

建立安裝目錄：

# mkdir -pv /usr/local/java

mkdir: created directory ‘/usr/local/java’

解壓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

檢測當前java版本：

# java -version

-bash: java: command not found

安裝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

檢測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)

配置環境變量：

# vi /etc/profile

添加內容：

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

 

使環境變量生效：source /etc/profile

 

4.安裝zookeeper（三節點僞分佈式集羣）：

下載zookeeper-3.3.6.tar.gz至/usr/local/src目錄

解壓zookeeper-3.3.6.tar.gz

# tar zxf zookeeper-3.3.6.tar.gz

建立安裝目錄：

# 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目錄：

# 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

編輯zoo.cfg，內容如下：

 

# 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.

dataDir=/usr/local/zookeeper/server01/data

dataLogDir=/usr/local/zookeeper/server01/logs

# the port at which the clients will connect

clientPort=2181

server.1=192.168.195.136:2888:3888

server.2=192.168.195.136:2889:3889

server.3=192.168.195.136:2890:3890

 

複製/usr/local/src/zookeeper-3.3.6至/usr/local/zookeeper/server01目錄下：

# cp -ar /usr/local/src/zookeeper-3.3.6 /usr/local/zookeeper/server01

# echo 1 > /usr/local/zookeeper/server01/data/myid

 

編輯/usr/local/src/zookeeper-3.3.6/conf/zoo.cfg，內容如下：

# 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.

dataDir=/usr/local/zookeeper/server02/data

dataLogDir=/usr/local/zookeeper/server02/logs

# the port at which the clients will connect

clientPort=2182

server.1=192.168.195.136:2888:3888

server.2=192.168.195.136:2889:3889

server.3=192.168.195.136:2890:3890

複製/usr/local/src/zookeeper-3.3.6至/usr/local/zookeeper/server02目錄下：

# cp -ar /usr/local/src/zookeeper-3.3.6 /usr/local/zookeeper/server02

# echo 2 > /usr/local/zookeeper/server02/data/myid

 

 

編輯/usr/local/src/zookeeper-3.3.6/conf/zoo.cfg，內容如下：

# 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.

dataDir=/usr/local/zookeeper/server03/data

dataLogDir=/usr/local/zookeeper/server03/logs

# the port at which the clients will connect

clientPort=2183

server.1=192.168.195.136:2888:3888

server.2=192.168.195.136:2889:3889

server.3=192.168.195.136:2890:3890

複製/usr/local/src/zookeeper-3.3.6至/usr/local/zookeeper/server03目錄下：

# cp -ar /usr/local/src/zookeeper-3.3.6 /usr/local/zookeeper/server03

# echo 3 > /usr/local/zookeeper/server03/data/myid

 

啓動zookeeper（zkServer.sh start）:

# /usr/local/zookeeper/server01/zookeeper-3.3.6/bin/zkServer.sh start

JMX enabled by default

Using config: /usr/local/zookeeper/server01/zookeeper-3.3.6/bin/../conf/zoo.cfg

JMX enabled by default

Using config: /usr/local/zookeeper/server01/zookeeper-3.3.6/bin/../conf/zoo.cfg

Mode: follower

 

5.安裝dubbo-monitor

 

下載dubbo-monitor-simple-2.5.3-assembly.tar.gz至/usr/local/src目錄

建立安裝目錄：

# mkdir -pv /usr/local/dubbo

mkdir: created directory ‘/usr/local/dubbo’

解壓dubbo-monitor-simple-2.5.3-assembly.tar.gz

# tar zxf dubbo-monitor-simple-2.5.3-assembly.tar.gz

複製/usr/local/src/dubbo-monitor-simple-2.5.3至/usr/local/dubbo目錄下：

# cp -ar /usr/local/src/dubbo-monitor-simple-2.5.3 /usr/local/dubbo

編輯dubbo.properties：

註釋如下內容：

dubbo.registry.address=multicast://224.5.6.7:1234

修改如下內容：

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

# vi dubbo.properties

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://192.168.195.136:2181?backup=192.168.195.136:2182,192.168.195.136:2183

#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=8088

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

 

 創建目錄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’

創建目錄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’

啓動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

檢查端口狀態：

# 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

tcp        0      0 0.0.0.0:8088            0.0.0.0:*               LISTEN      off (0.00/0/0)

 

6.安裝tomcat，並安裝配置dubbo-admin

下載apache-tomcat-7.0.69.tar.gz至/usr/local/src目錄

解壓apache-tomcat-7.0.69.tar.gz

# tar zxf apache-tomcat-7.0.69.tar.gz

建立安裝目錄/usr/local/dubbo/dubbo-admin-tomcat：

# mkdir -pv /usr/local/dubbo/dubbo-admin-tomcat

mkdir: created directory ‘/usr/local/dubbo/dubbo-admin-tomcat’

複製/usr/local/src/apache-tomcat-7.0.69目錄下所有文件至/usr/local/dubbo/dubbo-admin-tomcat目錄下：

（注：不包含/usr/local/src/apache-tomcat-7.0.69目錄本身）

# cp -ar /usr/local/src/apache-tomcat-7.0.69/. /usr/local/dubbo/dubbo-admin-tomcat

刪除tomcat自帶的webapps/ROOT目錄：

# rm -rf /usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT

下載dubbo-admin-2.5.3.war至/usr/local/src目錄

解壓dubbo-admin-2.5.3.war至/usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT目錄:

# unzip /usr/local/src/dubbo-admin-2.5.3.war -d /usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT

編輯/usr/local/dubbo/dubbo-admin-tomcat/webapps/ROOT/WEB-INF/dubbo.properties文件：

修改如下內容：

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

 


啓動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

Tomcat started.

檢測端口及進程狀態：

# netstat -nlp | grep 8080

tcp6       0      0 :::8080                 :::*                    LISTEN      16979/java          

# ps -ef | grep 16979

root      16979      1  5 21:23 pts/0    00:00:03 /usr/local/java/jdk1.7.0_79/jre/bin/java -Djava.util.logging.config.file=/usr/local/dubbo/

dubbo-admin-tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.endorsed.dirs=/usr/local/dubbo/dubbo-admin-tomcat/endorsed -classpath /usr/local/dubbo/dubbo-admin-tomcat/bin/bootstrap.jar:/usr/local/dubbo/dubbo-admin-tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/dubbo/dubbo-admin-tomcat -Dcatalina.home=/usr/local/dubbo/dubbo-admin-tomcat -Djava.io.tmpdir=/usr/local/dubbo/dubbo-admin-tomcat/temp org.apache.catalina.startup.Bootstrap startroot      16995   2539  0 21:24 pts/0    00:00:00 grep --color=auto 16979

 

7.訪問dubbo

http://192.168.195.136:8080

用戶名：root

密碼：root

 

8.重啓機器後，需要先啓動zookeeper，然後啓動dubbo-monitor，最後啓動dubbo-admin（即tomcat）。
