由于公司网站需要放置视频，但是默认的服务器环境是没有编译这个支持的模块，视频文件只能缓冲完了在播放，非常麻烦。
之前呢也安装了一个nginx_mod_h264_streaming来支持，效果很不错，但是服务器最近系统更新后出了点问题，只好从新编译，今天在nginx官网看到了nginx在新版本中已经支持了--with-http_mp4_module --with-http_flv_module这2个模块。所以就来自己编译吧。
编译之前我们需要看看之前编译的参数，使用nginx -V查看得到如下参数
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module
接下来就进入之前安装的目录，我用的是lnmp1.0的脚本安装的，文件地址在/root/lnmp1.0-full
当然我的nginx是我后来更新过的，版本是1.4.3，再次进入nginx-1.4.3这个目录
备份之前的程序配置
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_mp4_module --with-http_flv_module
等待结束，查看是否报错（应该不会报错，因为用的都是nginx默认支持的模块，不是外挂的）正常文件如

编译
make
nginx -t
如果提示如下命令就证明没有问题，就可以升级了
