Step 2 - Configure Nginx as a Service
Step 1. Install
Reference : https://www.howtoforge.com/tutorial/how-to-install-nginx-with-rtmp-module-on-centos/
Install Dependencies
In this tutorial, we will build the Nginx web server from source. We need to install all packages dependencies needed, including development tools, EPEL repository, and other packages.
Install CentOS 'Development Tools'.
> sudo yum -y groupinstall 'Development Tools'
Add the EPEL repository.
> sudo yum -y install epel-release
Install Nginx dependencies.
> sudo yum install -y wget git unzip perl perl-devel perl-ExtUtils-Embed libxslt libxslt-devel libxml2 libxml2-devel gd gd-devel pcre-devel GeoIP GeoIP-devel
Wait for all packages installed.
Download Nginx with Additional Package and RTMP Module
In this step, we will download nginx source code with the additional dependencies including pcre, zlib, and the OpenSSL.
Go to the '/home/gigasurv/Downloads/nginx/build' directory. (설치 Directory)
> cd /home/gigasurv/Downloads/nginx/buildDownload Nginx 1.14.0 and extract it.
> wget https://nginx.org/download/nginx-1.18.0.tar.gz
> tar -xzvf nginx-1.18.0.tar.gzDownload the pcre package and extract it.
> wget https://ftp.pcre.org/pub/pcre/pcre-8.42.zip
> unzip pcre-8.42.zipDownload the zlib package and extract it.
> wget https://www.zlib.net/zlib-1.2.11.tar.gz
> tar -xzvf zlib-1.2.11.tar.gzDownload the OpenSSL package and extract it.
> wget https://www.openssl.org/source/openssl-1.1.1h.tar.gz
> tar -xzvf openssl-1.1.1h.tar.gzNext, clone the Nginx RTMP Module source code using git command.
> git clone https://github.com/sergey-dryabzhinsky/nginx-rtmp-module.git
> sudo git clone git://github.com/arut/nginx-rtmp-module.gitAnd remove all compressed tar.gz and .zip files.
> rm -f *.tar.gz *.zipFollowing are the directory details we have.
> ls -lah

- make
make 과정 중에 rtmp module의 switch case 문에서 implicit-fallthrough 에러가 발생하는데, 문법 버전 error로 보이는데 명확한 이유를 확인할 수 없어 우선 no-error처리하였다. 설치 home directory(나의 경우/home/gigasurv/Downloads/nginx/build) 하위의 nginx-1.18.0/nginx-1.18.0/Makefile CFLAGS에 -Wno-error=implicit-fallthrough 를 추가한다.
CC = cc CFLAGS = -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g -Wno-error=implicit-fallthrough CPP = cc -E LINK = $(CC) ...
- make install
> make install
Create nginx symlink module to the '/etc/nginx' configuration directory.
> sudo ln -s /usr/lib64/nginx/modules /etc/nginx/modules
Create a new 'nginx' system user and group.
> sudo useradd -r -d /var/cache/nginx/ -s /sbin/nologin -U nginx
Now create a new Nginx cache directory '/var/cache/nginx' and change the owner of the directory to 'nginx' user and group.
> sudo mkdir -p /var/cache/nginx/
> sudo chown -R nginx:nginx /var/cache/nginx/
Test nginx configuration and the installed nginx version.
> nginx -t
> nginx -VAnd the following is the result.
The Nginx web server has been installed on CentOS 7 with the RTMP Module enabled.
Step 2 - Configure Nginx as a Service
In this tutorial, we will be running nginx as a service and we need to create a new nginx service file to the systemd service directory.
Go to the '/lib/systemd/system' directory and create a new 'nginx.service' file using vim.
> cd /lib/systemd/system/
> vim nginx.service
paste the configuration below.Advertisement
[Unit]
Description=nginx - high performance web server
Documentation=https://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target
[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
[Install]
WantedBy=multi-user.target
Save and exit.
Now reload the systemd system.
> systemctl daemon-reload
Start the nginx service and enable it to launch everytime at system boot.
> systemctl start nginx
> systemctl enable nginxThe Nginx web server is up and running as a service on CentOS 7 system.
Step 3. Configure
Configure Nginx RTMP Module
In this step, we will create a new custom Nginx configuration for RTMP module.
Go to the '/etc/nginx' configuration directory and backup the original 'nginx.conf' file.
> cd /etc/nginx/
> mv nginx.conf nginx.conf.asliNow create a custom configuration 'nginx.conf'.
> vim nginx.confPaste Nginx RTMP configuration below.
```
worker_processes auto;
events {
worker_connections 1024;
}
# RTMP configuration
rtmp {
server {
listen 1935; # Listen on standard RTMP port
chunk_size 4000;
application show {
live on;
# Turn on HLS
hls on;
hls_path /var/www/hls/;
hls_fragment 3;
hls_playlist_length 60;
# disable consuming the stream from nginx as rtmp
deny play all;
}
application live {
live on;
}
# RTMP video on demand for mp4 files
application vod {
play /var/www/vod;
}
}
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
#server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
#root html;
root /var/www;
index index.html index.htm;
# Disable cache
add_header 'Cache-Control' 'no-cache';
# CORS setup
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Expose-Headers' 'Content-Length';
# allow CORS preflight requests
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
types {
application/dash+xml mpd;
application/vnd.apple.mpegurl m3u8;
video/mp2t ts;
}
}
}
# Another Virtual Server ...
}
```
Save and exit.
Next, we need to create a new directory for the HLS configuration and we've defined the web root directory is on the '/var/www/hls' directory.
Create the 'hls' directory under the '/var/www/hls' directory and change the owner of the directory to the nginx user and group.
> mkdir -p /var/www/hls
> chown -R nginx:nginx /var/www/hls
Test the configuration and restart the nginx service.
> nginx -t
> systemctl restart nginxSetup First RTMP Live Stream
In this tutorial, we will create new RTMP stream video on demand using the mp4 videos on the server, and create a new live RTMP stream that will be broadcasted from the local computer using the OBS software.
Go to the '/etc/nginx' configuration directory and edit the 'nginx.conf' file.
> cd /etc/nginx/
> vim nginx.conf
Paste configurations below in to the 'rtmp { ... }' bracket.
```
# RTMP video on demand for mp4 files
application vod {
play /var/www/vod;
}
# RTMP stream using OBS
application stream {
live on;
}
```
Save and exit.
Now create a new directory 'vod' for storing all vod videos, and change the owner to the nginx user group.
> mkdir -p /var/www/vod
> chown -R nginx:nginx /var/www/vod
Test nginx configuration and make sure there is no error, then restart the nginx service.
> nginx -t
> systemctl restart nginxNginx configuration for the RTMP live stream and the vod stream has been completed.

Open port 80 and 443 using firewall-cmd
You must open and enable port 80 and 443 using the firewall-cmd command:
> sudo firewall-cmd --permanent --zone=public --add-service=http --add-service=https
> sudo firewall-cmd --reload
> sudo firewall-cmd --list-services --zone=public
dhcpv6-client http https nfs ntp samba sshStep 4 - Testing
Test RTMP live stream and vod stream using the VLC player.
Video On Demand Stream
Open the VLC app on your computer.
Click the 'File' menu choose the 'Open Network' option.
Now type the RTMP URL for our vod stream.
rtmp://host_address:1935/vod/file.mp4
Click the 'Open' button.
And the following are the results of the video stream.
