Build nginx-1.18.0 + rtmp server under Ubuntu 18.04

To build a live broadcast platform recently, you need to build servers under Linux and Windows separately, and use two blogs to record the build process

1. Download and install nginx and nginx-rtmp-module compilation dependency tools

sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev

2. Create working directory

mkdir nginx
cd nginx

3. Download the source code of nginx and nginx-rtmp-module

#下载nginx源码并解压
wget http://nginx.org/download/nginx-1.18.0.tar.gz
tar -zxvf nginx-1.18.0.tar.gz
#下载nginx-rtmp-module源码
git clone https://github.com/arut/nginx-rtmp-module.git

4. Compile and install nginx

cd nginx-1.18.0
./configure --add-module=../nginx-rtmp-module --with-http_ssl_module #将rtmp模块编译到nginx
make
make install #或 sudo make install

5. Start nginx service

sudo systemctl start nginx
#不出意外，会报下面的错误
Failed to start nginx.service: Unit nginx.service not found

Add nginx to systemctl

cd /usr/lib/systemd/
sudo mkdir system #如果存在该目录直接进入，不存在创建
cd system
sudo touch nginx.service
sudo vi nginx.service

Add the following

[Unit]

Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network.target remote-fs.target nss-lookup.target
 
 
[Service]
 
Type=forking
WorkingDirectory=/usr/local/nginx               #此处位置为你的nginx安装目录，根据实际情况进行更改(删掉)
ExecStart=/usr/local/nginx/sbin/nginx           #此处位置为你的nginx安装目录中的nginx可执行文件位置，根据实际位置进行更改(删掉)
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
 
 
[Install]
 
WantedBy=multi-user.target

#使文件生效
sudo systemctl daemon-reload

6. Start nginx service again

sudo systemctl start nginx

Enter the server IP in the browser, the following familiar content appears

7. Add the configuration of the rtmp module in the configuration file and start the rtmp service

#进入nginx安装目录的conf目录下修改配置文件
cd /usr/local/nginx/conf/

sudo vi nginx.conf
sudo vi nginx.conf.default

Add the following content (both files need to be added)

rtmp {
    
    
    server {
    
    
        listen 1935;

        application rtmplive {
    
    
            live on;
            max_connections 1024;
        }
    }
}

8. Restart nginx server

sudo systemctl restart nginx

9. FFmpeg streaming

ffmpeg -f dshow -i video="USB2.0 Camera" -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://nginx server IP:1935/rtmplive/123

10. VLC pull stream
    
    
11. Shut down the server

sudo systemctl stop nginx
