错误：调遣hbase包错误，配置文件不能加载。
解决：将hbase目录下jar包拷贝到hadoop/lib下。
以下都是未找到jar包，解决方法如上，将hadoop加载的应用程序jar拷贝到hadoop/lib下。

Nginx启动报错：

Nginx启动报错：10013: An attempt was made to access a socket in a way forbidden

Nginx在win7，win2008下启动报错：bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions) 。

原因是Win7下nginx默认80端口被System占用，造成nginx启动报错的解决方案。

在cmd窗口运行如下命令：

 

[plain]

C:\Users\Administrator>netstat -aon | findstr :80  

 

看到80端口果真被占用。发现占用的pid是4，名字是System。怎么禁用呢？

 

1、打开注册表：regedit

 

2、找到：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP

 

3、找到一个REG_DWORD类型的项Start，将其改为0

 

4、重启系统，System进程不会占用80端口

 

重启之后，start nginx.exe 。在浏览器中，输入127.0.01，即可看到亲爱的“Welcome to nginx!” 了。
