dubbo+zookeeper+ssm 分布式項目搭建隨記

1.配置主機的映射(默認為127.0.0.1  localhost)

修改C:\Windows\System32\drivers\etc目錄下的hosts文件(默認為空，屬性為只讀)

取消只讀   在空白文件中加入127.0.0.1  www.cjq.com 映射

2.配置分布式的服務和web

修改當前tomcat服務器下的server.xml文件：

3.運行zookeeper服務器

F:\TestProject1\zookeeper-3.4.8\bin目錄下的zkServer.cmd

4.進入項目的目錄下運行mavan install

例如：F:\TestProject1\tools\web-tools目錄下開啟cmd命令窗口

運行mvn clean install -Dmaven.test.skip

5.服務器下新增數據庫配置文件dtools.properties

#jdbc setting
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/tools
username=root
password=root
initialSize=0
maxActive=20
maxIdle=20
minIdle=1
maxWait=60000

#dubbo setting

#img setting
imgPath=G:/workspace/upload/imgUpload/
imgTempPath=G:/workspace/upload/imgTempUpload/
imgDestPath=G:/workspace/upload/imgDestUpload/
#file setting
fileSavePath=G:/workspace/upload/fileUploadPath
fileDestSavePath=G:/workspace/upload/fileDestUploadPath
fileTmpSavePath=G:/workspace/upload/fileTmpUploadPath

#video setting
videoDesPath=G:/workspace/upload/fileVideoDesUploadPath

#dubbo setting
dubboRegister1=zookeeper://127.0.0.1:2181
dubboBasePortProvide=20880
dubboToolPortProvide=20881
dubboName=dubbo

#resource setting
resourcePath=/usr/local/program/resource

 6.tomcat服務器主頁設置

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

 。。。。。。

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

</web-app>

7./user/local路徑

Linux 的軟件安裝目錄是也是有講究的，理解這一點，在對系統管理是有益的

/usr：系統級的目錄，可以理解為C:/Windows/，/usr/lib理解為C:/Windows/System32。
/usr/local：用戶級的程序目錄，可以理解為C:/Progrem Files/。用戶自己編譯的軟件默認會安裝到這個目錄下。
/opt：用戶級的程序目錄，可以理解為D:/Software，opt有可選的意思，這里可以用於放置第三方大型軟件（或游戲），當你不需要時，直接rm -rf掉即可。在硬盤容量不夠時，也可將/opt單獨掛載到其他磁盤上使用。

源碼放哪里？
/usr/src：系統級的源碼目錄。
/usr/local/src：用戶級的源碼目錄。

8.java Properties類  讀取配置文件

它提供了幾個主要的方法：

1． getProperty ( String key)，用指定的鍵在此屬性列表中搜索屬性。也就是通過參數 key ，得到 key 所對應的 value。

2． load ( InputStream inStream)，從輸入流中讀取屬性列表（鍵和元素對）。通過對指定的文件（比如說上面的 test.properties 文件）進行裝載來獲取該文件中的所有鍵 - 值對。以供 getProperty ( String key) 來搜索。

3． setProperty ( String key, String value) ，調用 Hashtable 的方法 put 。他通過調用基類的put方法來設置 鍵 - 值對。

4． store ( OutputStream out, String comments)，以適合使用 load 方法加載到 Properties 表中的格式，將此 Properties 表中的屬性列表（鍵和元素對）寫入輸出流。與 load 方法相反，該方法將鍵 - 值對寫入到指定的文件中去。

5． clear ()，清除所有裝載的 鍵 - 值對。該方法在基類中提供。

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

9.java中給我們提供了System.getProperty()這個函數，這個函數可以獲取到java JVM以及操作系統的一些參數，可以供程序判斷等。

<span style="font-size:18px">System.getProperty("java.vm.version");//java虛擬機版本
System.getProperty("java.vendor.url"); //java官方網站
System.getProperty("java.vm.nam"); //java虛擬機名稱
System.getProperty("user.country"); //國家或地區
System.getProperty("user.dir"); //工程的路徑
System.getProperty("java.runtime.version");//java運行環境版本
System.getProperty("os.arch"); //操作系統位數（32或64）
System.getProperty("os.name"); //操作系統名稱
System.getProperty("sun.jnu.encoding"); //編碼格式
System.getProperty("os.version"); //操縱系統版本
System.getProperty("java.version"); //java版本版本</span>

System.getProperty("catalina.home") ，Tomcat 安裝目錄，一般是用來查找庫 jar 的。
System.getProperty("catalina.base")，服務器配置目錄，所有配置文件都在這里，你可以用一個catalina.home 來啟動兩個命令行來運行兩個不同的 catalina.base 配置（前提你已經修改了配置文件保證它們的端口不會沖突）；

當在 eclipse 里面運行時，多數情況下 cataline.home 還是 tomcat 目錄，而 catalina.base 是 eclipse workspace 里面的一個目錄，你現在需要拿到的應該是工作時的配置目錄下的子目錄

，所以你應該用 catalina.base 當成根目錄；比如，我想讀取 tomcat user 文件，得到的結果相當於 ${cataline.base}/conf/tomcat-users.xml

項目部署到tomcat時WEB-INF目錄下缺少lib包
項目右鍵-Properties-Deployment Assembly-Add-java build path entries點擊進去添加mavan依賴的jar包
