老师这里为啥访问不了admin啊，之前安装uwsgi可以访问admin，安装nginx可以正常访问nginx,安装了两次每次步骤和实现的情况都没什么问题，就是这里配置项目，nginx配置后尝试访问admin访问不了，404错误。
老师：
你这个运行是什么软件？如何安装极使用，有相关的说明书没有？
老师，这一节声音有问题？？？？？？？？？？？？？？？？？？？

把Apachehe和mySQL都打开了没有报错后面就不用修改了吧，还是可以修改了以后就不会报错了
老师，我这里为什么这些文件展示不出来？？
下载这个应该没有事吧，，好像什么都有，课程里的文档还没下载下来
老师，第一个问题，怎么一会儿说调用它的线程进入阻塞状态，一会又说其他线程处于阻塞状态？
第二个问题，调用该方法的线程强制执行，其他线程处于阻塞状态，那为什么只有main被阻塞了，t2还能和t抢？
老师，我的mysql版本为5.7.12-log。那我pom文件咋配

老师如果我不想覆盖掉第一个项目那么我部署的第二个项目的<path>标签里应该写成这样吗？<path>/</path>
直接放到webapps目录下，然后启动Linux下的Tomcat输入端口号后面跟父项目的项目名？
<build> <plugins> <!-- 配置 Tomcat 插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <!-- path: 上传的 war 包解压后的路径命名 --> <path>/</path> <!-- url : 上传 war 包到什么位置 , 除 IP 和端口可以修改外其他不变 --> <url>http://10.6.226.45:8080/manager/text</url> <!-- 为 tomcat 配置的管理用户名和密码 . --> <username>tomcat</username> <password>tomcat</password> </configuration> </plugin> </plugins> </build>
老师讲的很好，麻烦把WORD课件发一下，配合做笔记，谢谢老师

老师就是这个了 工具类使用不了 然后全局配置文件也不知道哪里报了一个异常
老师，main线程会抢的比较快吗。。。我测试了7，8次都是main的循环跑完了 另一个线程才跑上，直到我把main的循环改成20，才在循环10次后看到交替出现
这讲一堆没听明白, fastDFS到底是个啥
是跟zookeeper一样的技术么,
讲一讲这两个的区别和联系, 听起来都像是文件系统+监听机制
