dubbo+zookeeper+ssm 分布式项目搭建随记

1.配置主机的映射(默认为127.0.0.1  localhost)

修改C:WindowsSystem32driversetc目录下的hosts文件(默认为空，属性为只读)

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

2.配置分布式的服务和web

修改当前tomcat服务器下的server.xml文件：

3.运行zookeeper服务器

F:TestProject1zookeeper-3.4.8in目录下的zkServer.cmd

4.进入项目的目录下运行mavan install

例如：F:TestProject1 oolsweb-tools目录下开启cmd命令窗口

运行mvn clean install -Dmaven.test.skip

5.服务器下新增数据库配置文件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服务器主页设置

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路径

Linux 的软件安装目录是也是有讲究的，理解这一点，在对系统管理是有益的

/usr：系统级的目录，可以理解为C:/Windows/，/usr/lib理解为C:/Windows/System32。
/usr/local：用户级的程序目录，可以理解为C:/Progrem Files/。用户自己编译的软件默认会安装到这个目录下。
/opt：用户级的程序目录，可以理解为D:/Software，opt有可选的意思，这里可以用于放置第三方大型软件（或游戏），当你不需要时，直接rm -rf掉即可。在硬盘容量不够时，也可将/opt单独挂载到其他磁盘上使用。

源码放哪里？
/usr/src：系统级的源码目录。
/usr/local/src：用户级的源码目录。

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

8.java Properties类  读取配置文件

它提供了几个主要的方法：

1． getProperty ( String key)，用指定的键在此属性列表中搜索属性。也就是通过参数 key ，得到 key 所对应的 value。

2． load ( InputStream inStream)，从输入流中读取属性列表（键和元素对）。通过对指定的文件（比如说上面的 test.properties 文件）进行装载来获取该文件中的所有键 - 值对。以供 getProperty ( String key) 来搜索。

3． setProperty ( String key, String value) ，调用 Hashtable 的方法 put 。他通过调用基类的put方法来设置 键 - 值对。

4． store ( OutputStream out, String comments)，以适合使用 load 方法加载到 Properties 表中的格式，将此 Properties 表中的属性列表（键和元素对）写入输出流。与 load 方法相反，该方法将键 - 值对写入到指定的文件中去。

5． clear ()，清除所有装载的 键 - 值对。该方法在基类中提供。

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

9.java中给我们提供了System.getProperty()这个函数，这个函数可以获取到java JVM以及操作系统的一些参数，可以供程序判断等。

<span style="font-size:18px">System.getProperty("java.vm.version");//java虚拟机版本
System.getProperty("java.vendor.url"); //java官方网站
System.getProperty("java.vm.nam"); //java虚拟机名称
System.getProperty("user.country"); //国家或地区
System.getProperty("user.dir"); //工程的路径
System.getProperty("java.runtime.version");//java运行环境版本
System.getProperty("os.arch"); //操作系统位数（32或64）
System.getProperty("os.name"); //操作系统名称
System.getProperty("sun.jnu.encoding"); //编码格式
System.getProperty("os.version"); //操纵系统版本
System.getProperty("java.version"); //java版本版本</span>

System.getProperty("catalina.home") ，Tomcat 安装目录，一般是用来查找库 jar 的。
System.getProperty("catalina.base")，服务器配置目录，所有配置文件都在这里，你可以用一个catalina.home 来启动两个命令行来运行两个不同的 catalina.base 配置（前提你已经修改了配置文件保证它们的端口不会冲突）；

当在 eclipse 里面运行时，多数情况下 cataline.home 还是 tomcat 目录，而 catalina.base 是 eclipse workspace 里面的一个目录，你现在需要拿到的应该是工作时的配置目录下的子目录

，所以你应该用 catalina.base 当成根目录；比如，我想读取 tomcat user 文件，得到的结果相当于 ${cataline.base}/conf/tomcat-users.xml

项目部署到tomcat时WEB-INF目录下缺少lib包
项目右键-Properties-Deployment Assembly-Add-java build path entries点击进去添加mavan依赖的jar包
