编译好之后，就是启动nginx了，`sudo service start nginx`启动的nginx不是自己编译的。

需要启动/usr/local/nginx/sbin/nginx，编译默认安装在这个目录下：

cd /usr/local/nginx
    sudo ./sbin/nginx
    sudo vi conf/nginx.conf

/usr/local/nginx/conf/nginx.conf文件内容

worker_processes  1;
    
    events {
        
        worker_connections  1024;
    }
    
    rtmp {
        
        server {
         
            listen 1935;
    	    chunk_size 4096;
            
            # rtmp点播
    	    application vod {
        
    		    play /opt/video/vod;
    	    }
    
            # rtmp直播
    	    application live{
         
    		    live on;
    	    }
        }
    }
    
    http {
        
        include            mime.types;
        default_type       application/octet-stream;
        sendfile           on;
        keepalive_timeout  65;
    
        server {
        
            listen       80;
            server_name  localhost;
    
    	    location /stat {
        
                rtmp_stat all;
    	        rtmp_stat_stylesheet stat.xsl;
    	    }
    
    	    location /stat.xsl {
        
    		    root nginx-rtmp-module;
    	    }
    
            location / {
        
                root   html;
                index  index.html index.htm;
            }
    
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
        
                root   html;
            }
        }
    }

stat的说明

location /stat {
        rtmp_stat all;
        rtmp_stat_stylesheet stat.xsl;
    }
    
    location /stat.xsl {
        root nginx-rtmp-module;
    }

*  添加stat.xsl，通过浏览器可以看到rtmp的status
 *  添加后http://localhost/stat可以查看，如果放在8080端口段，就是http://localhost:8080/stat
 *  stat.xsl文件从nginx-rtmp-module代码目录下copy到/usr/local/nginx/nginx-rtmp-module
 *  nginx-rtmp-module写的是相对于/usr/local/nginx下的相对路径也可以。

浏览器里面查看stat  
输入localhost/stat，就可以看到熟悉的页面，[截图][Link 1]

然后执行nginx reload

sudo ./sbin/nginx -s reload

或者

sudo killall nginx
    sudo ./sbin/nginx -c etc/nginx.conf

通过vlc或者ffplay都可以播放

vlc rtmp://localhost/vod/panda.mp4
    ffplay rtmp://localhost/vod/panda.mp4

journalctl可以查看nginx运行的日志

$ journalctl -u nginx
    
    9月 16 16:43:51 hui gnome-shell[7841]: [AppIndicatorSupport-WARN] Attempting to re-register :1.2/StatusNotifierItem; resetting instead
    9月 16 16:43:51 hui gnome-shell[7841]: [AppIndicatorSupport-WARN] Item :1.2/StatusNotifierItem is already registered
    9月 16 16:43:54 hui sudo[30907]:      hui : TTY=pts/11 ; PWD=/home/hui/disk4t/codes/nginx/nginx-1.18.0 ; USER=root ; COMMAND=/usr/bin/vi /etc/nginx/nginx.conf

nginx -t测试说明 nginx 配置是正确的，同时也可以发现load的nginx.conf文件对不对

$ sudo ./sbin/nginx -c etc/nginx.conf -t
    nginx: the configuration file /usr/local/nginx/etc/nginx.conf syntax is ok
    nginx: configuration file /usr/local/nginx/etc/nginx.conf test is successful

如果没有用-c指定etc/nginx.conf，load的conf文件是conf/nginx.conf，不是etc/nginx.conf，用了-c和不用-c是有区别的，修改conf文件最好修改conf/nginx.conf，这样不会有修改了不生效的问题。

$ sudo ./sbin/nginx -t
    nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
    nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
