Using nginx + nginx-rtmp-module + ffmpeg to build a streaming media server (6)

: This article mainly introduces how to use nginx + nginx-rtmp-module + ffmpeg to build a streaming media server (6). If you are interested in the PHP Tutorial, refer to it. Part 6

This problem has been plagued by the nginx startup problem that has been transplanted to the ARM Development board a few days ago. it does not occur when started on the ARM Development Board.

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

Is to appear

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

Use commands

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

The permission has not been changed. The permission cannot be modified.

It is always unsuccessful.

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

With the help of my tutor, I pushed the cross-compiled nginx folder to the/data/misc/directory instead of the/sdcard/mynginx/directory.

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

Re-run or error

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

Then modify the nginx. conf file

#user  nobody;

Remove the comment and change it

user  nobody;

Modify the running command and run it in the/data/misc/nginx/sbin/directory.

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

Run successfully.

Use commands

ps

You can view the running items:

root      2743  1     1328   456   c003f614 4002be64 S nginxnobody    2745  2743  1528   664   c00d8ad4 4002b7a4 S nginxroot      2748  2708  956    332   00000000 40095448 R ps

It indicates that nginx runs successfully.

Open your browser on the development board and enter

http://localhost/

Reality:

Nginx runs successfully.

Use commands

killall nginx

Kill the nginx process.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Every ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To sum up, you do not have the permission to run the nginx command on the sdcard or tfcard of the development board and change it to the/data/directory.

The default nginx is successfully transplanted. Next, add the rtmp module for nginx.
