Real Time Messaging Protocol (RTMP) is a trademarked protocol, formerly developed by Macromedia.
Macromedia now owned by Adobe. RTMP can do real-time streaming of video, audio, and data between a server and Flash player. However Adobe has declared that it will no longer support Flash, RTMP remains a usually used protocol for live streaming within production workflows.
• RTMP: Real Time messaging protocol works on top of TCP and uses port number 1935 by default.
• RTMPS, is a secure procedure of RTMP over a TLS/SSL connection.
• RTMPE, The RTMPE is RTMP encrypted by Adobe’s own security mechanism. While the details of the operation are proprietary, the mechanism uses industry standard cryptographic primitives.
RTMP Media server With Nginx RTMP module.
https://www.nginx.com/products/nginx/modules/rtmp-media-streaming/
HLS and RTMP can easily integrates with the Nginx web server without any issue using the Nginx RTMP module.
Nginx RTMP is an Nginx module which permits you to enhance HLS and RTMP streaming to your media server. So in this tutorial we are going to implement RTMP Media server With Nginx RTMP module On Centos.

First of we need to install all dependencies which are required by nginx-rtmp module.
Next, you have to download the pcre package execute the following to do so.
[root@linuxp~]#wget https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz
Extract the downloaded file.
[root@linuxp~]#cd pcre-8.42
[root@linuxp~]#./configure
[root@linuxp~]#make && make install
[root@linuxp~]#cd ../
Next, you have to download the zlib package and extract it using the following commands.
Extract the downloaded file.
[root@linuxp~]#cd zlib-1.2.11
[root@linuxp~]#./configure
[root@linuxp~]#make && make install
Next, download the OpenSSL package and extract it.
[root@linuxp~]#tar -xvf openssl-1.0.2q.tar.gz
[root@linuxp~]#cd openssl-1.0.2q
[root@linuxp~]#./config && make && make install
Download Nginx and require other Additional Package
You have installed all required dependencies , so now download and install Nginx source with some other additional packages.
To do so you need to change your current directory to ‘/usr/local/src’ by the following command.
Next, you will need to extract the above-downloaded file using the following command.
After that, clone/pull the Nginx RTMP Module source code executing the git command.
Compile and Install Nginx
After downloading the Nginx with all the other required additional packages. So, let’s install and configure Nginx. To do so change your current directory to ‘nginx-1.14.2’.
[root@linuxp~]#./configure –add-module=../nginx-rtmp-module –sbin-path=/usr/sbin/nginx –lock-path=/var/run/nginx.lock –conf-path=/etc/nginx/nginx.conf –pid-path=/run/nginx.pid –with-pcre=../pcre-8.42 –with-zlib=../zlib-1.2.11 –with-openssl=../openssl-1.0.2q –error-log-path=/var/log/nginx/error.log –http-log-path=/var/log/nginx/access.log –user=nginx –group=nginx –with-http_auth_request_module –with-http_degradation_module –with-http_geoip_module –with-http_gunzip_module –with-http_gzip_static_module –with-http_image_filter_module –with-http_mp4_module –with-http_perl_module –with-http_realip_module –with-http_secure_link_module –with-http_slice_module –with-http_ssl_module –with-http_stub_status_module –with-http_v2_module –with-stream_ssl_module –with-stream –with-threads –prefix=/etc/nginx
[root@linuxp~]#make && make install
[root@linuxp~]#cp nginx-1.14.2/man/nginx.8 /usr/share/man/man8
[root@linuxp~]#cp man/nginx.8 /usr/share/man/man8
[root@linuxp~]#gzip /usr/share/man/man8/nginx.8
[root@linuxp~]#useradd –system –home /var/lib/nginx –shell /sbin/nologin –comment “nginx system user” nginx
[root@linuxp~]#mkdir /var/log/nginx && sudo chown nginx:nginx /var/log/nginx
[root@linuxp~]#vi /lib/systemd/system/nginx.service
Append the following line to generate new startup file.

After creating new system daemon file run the following command to update the kernel about changes.
[root@linuxp~]#systemctl start nginx
[root@linuxp~]#systemctl enable nginx
[root@linuxp~]#cd /etc/nginx/
[root@linuxp~]#cp nginx.conf nginx.conf_backup
[root@linuxp~]#rm -rf nginx.conf
[root@linuxp~]# vi nginx.conf
And append the following lines in your nginx.conf

Afer putting the following config file. Run the following command on your server terminal.
[root@linuxp~]#cd /var/www/
[root@linuxp~]#ln -s /etc/nginx/html/ html
[root@linuxp~]# systemctl restart nginx
In this tutorial we are going to implement nginx-rtmp streaming server with multi bitrate so that user can access streaming according his internet speed.
To enable multi bitrate we require to install FFMPEG tool, So here are the steps to install FFMPEG.
[root@linuxp~]#rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
[root@linuxp~]#yum install ffmpeg ffmpeg-devel
[root@linuxp~]#ffmpeg -version

I am founder and webmaster of www.linuxpcfix.com and working as a Sr. Linux Administrator (Expertise on Linux/Unix & Cloud Server) and have been in the industry since more than 14 years.
hls fragmented files deleted after a while i upload them to the server!
here is my hls config:
# Define the Application
application show {
live on;
# Turn on HLS
hls on;
hls_path /mnt/hls/;
hls_cleanup off;
hls_playlist_length 10y;
hls_fragment 3;
……
Any Idea!TNX.
The hls fragment files automatically deleted once broadcasting stopped
