Notes on using nginx+nginx-rtmp-module+ffmpeg to build a streaming media server (6)

Part 6

A few days ago, I have been troubled by the problem of starting nginx transplanted to the ARM development board. When starting on the ARM development board, either

nginx: [emerg] getgrnam("nogroup") failed (2: No such file or directory)

or

/system/bin/sh: ./nginx: cannot execute - Permission denied 

appears. Use the command

adb shell chmod 755 /sdcard/mynginx/sbin/nginx

to modify permissions. No changes were made, and the permission modification was unsuccessful.

Always fails to run.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~

Today, with the help of my tutor, I pushed the cross-compiled nginx folder to the /data/misc/ directory instead of Re-run

adb push /sdcard/nginx/  /data/misc/nginx/

under /sdcard/mynginx/, but an error still occurs

nginx: [emerg] getgrnam("nogroup") failed (2: No such file or directory)

Then modify the nginx.conf file, remove the comment

#user  nobody;

in the first line, change it to

user  nobody;

, and then modify Run the command in the /data/misc/nginx/sbin/ directory and execute it successfully.

Use the command

./nginx  -p  /data/misc/nginx  -c  conf/nginx.conf

to view the running items:

ps

indicating that nginx is running successfully.

Open the browser on the development board and enter

root      2743  1     1328   456   c003f614 4002be64 S nginx
nobody    2745  2743  1528   664   c00d8ad4 4002b7a4 S nginx
root      2748  2708  956    332   00000000 40095448 R ps

The following page appears

nginx runs successfully.

Use the command

http://localhost/

to kill the nginx process.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In summary, there is no permission to execute the nginx command on the sdcard or tfcard of the development board. Change to the /data/ directory .

The default nginx was successfully transplanted. The next step is to add the rtmp module to nginx.

The above introduces the notes (6) on building a streaming media server using nginx+nginx-rtmp-module+ffmpeg, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
