; The [include] section can just contain the “files” setting.
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files cannot
; include files themselves.
[include]
;files = supervisord.d/.ini
files = supervisord.d/.conf
There is almost no need to change the configuration information, just add files = supervisord.d/*.conf at the end, and comment out ;files = supervisord.d/*.ini
1
The next step is to create a configuration file in the /etc/supervisord.d directory, such as test.conf, with the following content:
[program:queue]
process_name=%(process_num)02d
\t
directory=/var/www/test //The root directory of the project
\t
command=php think queue:work --queue sendNotify --daemon
\t
autostart=true
\t
autorestart=true
\t
user=root
\t
numprocs=5
\t
redirect_stderr=true
\t
stdout_logfile=/var/www/test/runtime/queue/sendNotify.log //log file, remember to create the directory first and give permission

3. Start the supervisor
supervisorctl -c /etc/supervisord.conf
1
Error, unix:///var/run/supervisor/supervisor.sock no such file
solve:
① sudo touch /var/run/supervisor/supervisor.sock
② sudo chmod 777 /var/run/supervisor/supervisor.sock
Still reporting an error, unix:///var/run/supervisor/supervisor.sock refused connection
solve:
① Try to restart the service service supervisord restart
② If you still report this error, check whether the test.conf configuration file is wrong, path permissions, etc.
4. Start the supervisor again
supervisorctl -c /etc/supervisord.conf
1
It should be normal at this time. If there is an error like entered FATAL state, too many start retries too quickly, check the configuration file. It is very likely that the writing is wrong, such as command=php /var/www/test/think queue: work --queue sendNotify --daemon without directory=/var/www/test //The root directory of the project, it is no problem to write this in the laravel project, but it may not be possible in tp5. I just survived the catastrophe here, and spent most of the day searching and modifying it, which was too uncomfortable.
