disconf之前有搭建过一次但是没有成功，比较纠结它的基于nginx实现动静分离的思想，其实明明可以少一个组件的依赖和配置，或许开发者有其自己的考虑吧。
这次终于搭建完毕并且跑通，下面写几个碰到但是官方文档中没给出的坎。
搭建项目
--就是一个disconf-web
安装依赖软件
- 安装Mysql（Ver 14.12 Distrib 5.0.45, for unknown-linux-gnu (x86_64) using EditLine wrapper）
- 安装Tomcat（apache-tomcat-7.0.50）
- 安装Nginx（nginx/1.5.3）
- 安装 zookeeeper （zookeeper-3.3.0）
- 安装 Redis （2.4.5）
准备配置
将你的配置文件放到此地址目录下（以下地址可自行设定）：
home/work/dsp/disconf-rd/online-resources配置文件包括：
- jdbc-mysql.properties (数据库配置)
- redis-config.properties (Redis配置)
- zoo.properties (Zookeeper配置)
- application.properties (应用配置）注意，记得执行将application-demo.properties复制成application.properties：
cp application-demo.properties application.properties设置War包将要被部署的地址（以下地址可自行设定）：
/home/work/dsp/disconf-rd/war构建
ONLINE_CONFIG_PATH=/home/work/dsp/disconf-rd/online-resources
WAR_ROOT_PATH=/home/work/dsp/disconf-rd/war
export ONLINE_CONFIG_PATH
export WAR_ROOT_PATH
cd disconf-web
sh deploy/deploy.sh这样会在 /home/work/dsp/disconf-rd/war 生成以下结果：
-disconf-web.war
-html
-META-INF
-WEB-INF上线前的初始化工作
初始化数据库：
可以参考 sql/readme.md 来进行数据库的初始化。
里面默认有6个用户
如果想自己设置初始化的用户名信息，可以参考代码来自己生成用户：
src/main/java/com/baidu/disconf/web/tools/UserCreateTools.java部署War
修改server.xml文件，在Host结点下设定Context：
<Context path="" docBase="/home/work/dsp/disconf-rd/war"></Context>并设置端口为 8015
启动Tomcat，即可。
部署 前端
修改 nginx.conf
upstream disconf {
server 127.0.0.1:8015;
}
server {
listen 8081;
server_name localhost;
access_log /home/work/var/logs/disconf/access.log;
error_log /home/work/var/logs/disconf/error.log;
location / {
root /home/work/dsp/disconf-rd/war/html;
if ($query_string) {
expires max;
}
}
location ~ ^/(api|export) {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_pass http://disconf;
}
}特别指出在打包项目时候请检查python库版本3.*版本会报错，请用2.*打包
第二点，在打出来的war包修改诸如zookeeper的配置时，必须重新打包，单纯修改war目录下的文件是无效的
使用
用户名密码 admin/admin
创建app，上传配置
1.添加disconf.properties配置文件
disconf.user_define_download_dir=./ 此处意思就是将zookeeper中的配置拉到本地的classpath下，若配置成其他目录，似乎会报错
1. disconf.enable.remote.cnotallow=true
2. disconf.conf_server_host=172.171.51.151:8082
3. disconf.versinotallow=1.0.0.0
4. disconf.app=17wifiServer
5. disconf.env=local
6. disconf.ignore=
7. disconf.conf_server_url_retry_times=1
8. disconf.conf_server_url_retry_sleep_secnotallow=1
9. disconf.user_define_download_dir=./
10. disconf.enable_local_download_dir_in_class_path=true
2.添加disconf.xml，并且指定给spring加载
配置如下
1. <?xml version="1.0" encoding="UTF-8"?>
2.
3. <beans xmlns="http://www.springframework.org/schema/beans"
4. "http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
5. //www.springframework.org/schema/beans
6. //www.springframework.org/schema/beans/spring-beans-3.1.xsd
7. //www.springframework.org/schema/aop
8. //www.springframework.org/schema/aop/spring-aop-3.0.xsd">
9. class="true"/>
10. <!-- 使用disconf必须添加以下配置 -->
11. "disconfMgrBean" class="com.baidu.disconf.client.DisconfMgrBean"
12. "destroy">
13. "scanPackage" value="com.fnic.wifi.server"/>
14. </bean>
15. "disconfMgrBean2" class="com.baidu.disconf.client.DisconfMgrBeanSecond"
16. "init" destroy-method="destroy">
17. </bean>
18. <!--################################################################ -->
19. <!-- 使用托管方式的disconf配置(无代码侵入, 配置更改会自动reload)-->
20. "configproperties_disconf"
21. class="com.baidu.disconf.client.addons.properties.ReloadablePropertiesFactoryBean">
22. "locations">
23. <list>
24. <value>classpath:jdbc.properties</value>
25. <value>classpath:redis.properties</value>
26. </list>
27. </property>
28. </bean>
29. "propertyConfigurer"
30. class="com.baidu.disconf.client.addons.properties.ReloadingPropertyPlaceholderConfigurer">
31. "ignoreResourceNotFound" value="true"/>
32. "ignoreUnresolvablePlaceholders" value="true"/>
33. "propertiesArray">
34. <list>
35. "configproperties_disconf"/>
36. </list>
37. </property>
38. </bean>
39. </beans>配置上半段是必须配置，下半段是将配置文件托管给spring，并且可以运用${}这样的形式配置在spring的xml中，可以参考jdbc数据源的配置
其中
1. <value>classpath:jdbc.properties</value>
2. <value>classpath:redis.properties</value>
3. 要和上面
4. disconf.user_define_download_dir=./ 对应起来
3.注释掉spring原本的加载配置类
1. <!-- <bean id="config"
2. class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
3. "locations">
4. <list>
5. <value>classpath:conf/jdbc.properties</value>
6. <value>classpath:conf/redis.properties</value>
7. </list>
8. </property>
9. </bean> -->
4.编写测试bean
1. @Component
2. @DisconfFile(filename = "configure.properties")
3. public class
4. private
5.
6. @DisconfFileItem(name = "resource_server_url", associateField = "resourceUrl")
7. public
8. return
9. }
10.
11. public void
12. this.resourceUrl = resourceUrl;
13. }
14.
15. }
ok启动就可以运用disconf了，其性能还有待验证，不过其原理应该是从zk中拉配置到本地内存中，同自己手动加载本地的property文件。
