    Started a new Droplet from a snapshot at DO and got the Intel(R) Xeon(R) Platinum 8168 CPU @ 2.70GHz this time and thought, well let's recompile all things but at the nginx part it hangs. This happend before on a old Droplet but I don't know if the make completed.

    Code (Text):
    ---------------------------------------------------------------------------
nginx master id:

kill -USR2
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

    Nginx 1.31.x
    MariaDB 10.x/11.4+/12.3+
    To troubleshoot, you need to check the full nginx upgrade log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the nginx_upgrade.log log. You can see full details at How to troubleshoot Centmin Mod initial install issues

    also what's output of
    Code (Text):
    nginx -t

    when you run centmin.sh menu option 4 there's a nginx upgrade log timestamped at /root/centminlogs

    if you type this command it lists all logs in date ascending order so latest log at bottom
    Code (Text):
    ls -lArt /root/centminlogs

    so copy the entire contents of latest nginx_upgrade log to gist.github.com or pastebin.com

    you can use grep to filter the logs, i.e. look for nginx_upgrade in log name
    Code (Text):
    ls -lahrt /root/centminlogs/ | grep nginx_upgrade
-rw-r--r--  1 root root 3.2M Oct 11 15:55 centminmod_1.2.3-eva2000.09.001_111016-155345_nginx_upgrade.log
-rw-r--r--  1 root root 672K Oct 11 22:06 centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log

    So the last nginx upgrade log was named centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log and located at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log

    then use cat command to output the contents of that log

    clear your ssh window buffer/screen and type
    Code (Text):
    cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log

    then select and copy and paste output to pastebin.com or gist.github.com file to share. If your SSH client's scroll buffer isn't large enough using cat might not output the entire log file contents, so you may need to download the log and use local text editor to open and copy and paste.

    so only need content of one specific log, in this case most recent nginx_upgrade.log log

    Solution was to kill all nginx processes.
    Code (Text):
    kill $(ps aux | grep '[n]ginx' | awk '{print $2}')

    Have to retest it, because I did several re-compiles, so don't remember the log files

    did any of your nginx recompiles end up with you forcing a abort i.e. ctrl+C etc ? you could abruptly interrupted the process and left nginx processes lingering

    did not work, so I used another terminal to force it to quit. But my recompile just finished without any errors.
