Nginx RTMP Media server With Nginx-RTMP module On Centos

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.

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.
http://www.linuxpcfix.com/nginx-load-balancer-on-centosrhelfedora/
First of we need to install all dependencies which are required by nginx-rtmp module.

[root@linuxp~]#yum install git wget gcc gcc-c++ tar gd gd-devel perl-ExtUtils-Embed geoip geoip-devel pcre pcre-devel openssl openssl-devel zlib zlib-devel –y

Next, you have to download the pcre package execute the following to do so.

[root@linuxp~]#cd /usr/local/src
[root@linuxp~]#wget https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz

Extract the downloaded file.

[root@linuxp~]#tar -xvf pcre-8.42.tar.gz
[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.

[root@linuxp~]#wget https://www.zlib.net/zlib-1.2.11.tar.gz

Extract the downloaded file.

[root@linuxp~]#tar -xvf zlib-1.2.11.tar.gz
[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~]#wget https://www.openssl.org/source/openssl-1.0.2q.tar.gz
[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.

[root@linuxp~]#wget https://nginx.org/download/nginx-1.14.2.tar.gz

Next, you will need to extract the above-downloaded file using the following command.

[root@linuxp~]#tar -xvf nginx-1.14.2.tar.gz

After that, clone/pull the Nginx RTMP Module source code executing the git command.

[root@linuxp~]#git clone https://github.com/sergey-dryabzhinsky/nginx-rtmp-module.git

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~]#cd 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 daemon-reload
[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~]#mkdir -p /var/www/hls/live
[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 -v –import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
[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
Nginx rtmp media server installation done. You can install OBS broadcaster on your local system to broadcast video/audio to your Nginx rtmp media server. The following url will use for streaming.
OBS URL :: rtmp://server-ip-address:1935/live
VOD URL :: rtmp://server-ip-address/videos/filename.mp4
HLS URL :: http://server-ip-address/live/_360/index.m3u8
http://server-ip-address/live/_480/index.m3u8
http://server-ip-address/live/_720/index.m3u8
