zookeeper
zookeeper官網(wǎng)地址：
http://zookeeper.apache.org/
官網(wǎng)quick-start教程：
http://zookeeper.apache.org/doc/current/zookeeperStarted.html
在官網(wǎng)找到下載地址
http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz
如果是本地安裝的話日丹，就直接點擊下載下來梨水，解壓就行
如果是遠(yuǎn)程服務(wù)器的話丁逝，可以在服務(wù)器上用curl下載
如果下載到本地想上傳到服務(wù)器的話戏蔑，可以用scp命令上傳到服務(wù)器（scp zookeeper-3.3.6.tar.gz root@xxx.xxx.xx.xx:/usr/）
我個人是安裝到阿里云的云服務(wù)器，過程如下：
進(jìn)入usr目錄新建個zookeeper目錄
cd /usr/
mkdir zookeeper
cd zookeeper/
通過curl下載安裝包并且解壓到當(dāng)前目錄
curl -O http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz
tar zxvf zookeeper-3.3.6.tar.gz
zookeeper 的啟動需要一個配置文件xx.cfg冤今，這個文件zookeeper-3.3.6/conf目錄下谨朝。默認(rèn)的是zoo_sample.cfg傻寂。我復(fù)制一份這個文件完沪，命名為zoo.cfg域庇。
cd zookeeper-3.3.6/conf/
cp zoo_sample.cfg zoo.cfg
然后返回zookeeper-3.3.6目錄，啟動下試試
./bin/zkServer.sh start
JMX enabled by default
Using config: /usr/zookeeper/zookeeper-3.3.6/bin/../conf/zoo.cfg
Starting zookeeper ... ./zkServer.sh:行103: /tmp/zookeeper/zookeeper_server.pid: 沒有那個文件或目錄
FAILED TO WRITE PID
報錯了覆积，看來是zoo.cfg中的默認(rèn)配置有問題听皿，得改一改
報錯找不到目錄，進(jìn)入zoo.cfg看到默認(rèn)的是 dataDir=/tmp/zookeeper宽档，這個目錄是真的不存在写穴，
在zookeeper-3.3.6下創(chuàng)建新的tmp目錄，修改dataDir為：dataDir=/usr/zookeeper/zookeeper-3.3.6/tmp
再試試
./bin/zkServer.sh start
JMX enabled by default
Using config: /usr/zookeeper/zookeeper-3.3.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
啟動成功
關(guān)閉命令就是：./zkServer.sh stop 唄
可以本地連接下
./bin/zkCli.sh -server localhost:2181
查看當(dāng)前節(jié)點列表：ls /
反正沒報錯并且有數(shù)據(jù)返回雌贱，感覺很完美
dubbo-admin
dubbo-admin就是在dubbo的官網(wǎng)下載個war包啊送，然后解壓到tomcat的ROOT目錄中，啟動tomcat就可以了欣孤。
wget http://apache.etoak.com/tomcat/tomcat-6/v6.0.35/bin/apache-tomcat-6.0.35.tar.gz
tar zxvf apache-tomcat-6.0.35.tar.gz
cd apache-tomcat-6.0.35
rm -rf webapps/ROOT
wget http://code.alibabatech.com/mvn/releases/com/alibaba/dubbo-admin/2.4.1/dubbo-admin-2.4.1.war
unzip dubbo-admin-2.4.1.war -d webapps/ROOT
但是我官網(wǎng)下載的war包啟動報錯馋没，我的jdk版本是1.8，而這個包最高只支持1.7降传，會報一個getter setter的錯篷朵。
ERROR context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uriBrokerService': Cannot create inner bean '(inner bean)' of type [com.alibaba.citrus.service.uribroker.impl.URIBrokerServiceImpl$URIBrokerInfo] while setting bean property 'brokers' with key [0]; nested excepti

解決方法有兩個
- 安裝1.7的jdk
- 去網(wǎng)上找個能用的包
為了省事，我去網(wǎng)上找的包婆排，地址如下：
http://download.csdn.net/download/sunpeng_sp/10155979
安裝好啟動tomcat声旺，直接訪問localhost:8080就可以進(jìn)入頁面了，賬號root密碼root
