FastDFS4 + Ubuntu12安装及部署1、 安装libevent
如果需要使用http进行下载，需要安装这个组件。
2、 安装fastdfs
3、 配置fastdfs
4、 安装nginx
问题4.1：安装nginx启动后访问原先资源URL出现404错误
#sudo gedit /nginx安装目录/conf/nginx.conf
在nginx.conf添加“user root;”并保存，重启nginx服务后OK
问题4.2：8090端口被占用
nginx: [emerg] bind() to 0.0.0.0:8090 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8090 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8090 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8090 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8090 failed (98: Address already in use)
nginx: [emerg] still could not bind()
#killall -9 nginx
// 中断nginx进程
# /nginx安装目录/sbin/nginx -s reload
// 重启nginx
问题4.3：nginx 403 Forbidden
nginx不允许访问请求的资源。可能的原因：
1.网站禁止特定的用户访问所有内容，例：网站屏蔽某个ip访问。
2.访问禁止目录浏览的目录，例：设置autoindex off后访问目录。
3.用户访问只能被内网访问的文件。
案例：在location{allow:all;}，我按照网上的例子一直设置为127.0.0.1，导致本机访问没有问题，但是局域网内电脑访问时始终报错。
5、 开机启动
6、 测试上传
7、 在c#中上传文件
