市面上优秀的流媒体服务器解决方案有很多，比如SRS，Red5，EasyDarwin，nginx-rtmp，live555，mediasoup
上传到linux服务器，然后解压压缩包
在/opt 下新建文件夹存放压缩包。比如 mkdir nginx-rtmp，然后将文件上传文件夹下解压缩。
$tar xvf nginx-1.20.1.tar.gz $unzip nginx-rtmp-module-master.zip
3.创建build目录
$cd nginx-1.20.1 $mkdir build
4.config & make & make install
yum -y install gcc gcc-c++ autoconf automake make
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
#配置nginx
#--prefix 指定安装的目录
#/usr/local/nginx 是安装目录，不能和自己下载的文件目录重了
#./configure --prefix=/usr/local/nginx
#带ssl stub_status模块 添加strem模块 –with-stream，这样就能传输tcp协议了
#http_stub_status_module 状态监控
#http_ssl_module 配置https
#stream 配置tcp得转发
#http_gzip_static_module 压缩
#http_sub_module 替换请求
--with-http_v2_module \
--with-http_flv_module \
--with-http_mp4_module \
（1）./configure --prefix=/opt/nginx-rtmp/nginx-1.20.2/build --add-module=/opt/nginx-rtmp/nginx-rtmp-module-1.2.2/
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gunzip_module --with-http_gzip_static_module --add-module=../nginx-rtmp-module
（2）make
（3）make install
补充：config过程中错误及错误处理
./configure: error: the HTTP rewrite module requires the PCRE library.
yum -y install pcre-devel
./configure: error: SSL modules require the OpenSSL library.
yum -y install openssl openssl-devel
./configure如果输出not found等不需要管，直接进行make；./configure是对nginx进行配置。
5.修改nginx配置文件
进入/opt/nginx-rtmp/nginx-1.20.2/build/conf/nginx.conf，增加rtmp服务器配置
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;

nginx报错：nginx: [emerg] unknown directive in /etc/nginx/conf.d/test.conf:4 解决: 第四行出现了 tab 空格 ， 换成正常的空格即可
6.启动 nginx
cd /opt/nginx-rtmp/nginx-1.20.2/build
sudo ./sbin/nginx
7.ffmpeg推流
ffmpeg -stream_loop -1 -v verbose -re -i sample_yuancore_720p.mp4 -f flv rtmp://192.168.41.115:1935/rtmp_live/mystream
-stream_loop -1 无限循环推流 -v verbose 详细日志 -re 本来的码率推流 -c:a copy -c:v copy 省略 按照原来编码推流
8.VLC拉流（直播、点播）
直播：rtmp://192.168.41.115:1935/rtmp_live/mystream 点播：rtmp://192.168.41.115:1935/rtmp_play/01.mp4
