phpsocket.io The script stops in the deamon mode

Hello everyone. I have some problem. Yesterday I have started script in the deamon mode. But today I have noticed that PHPSocket.io script is stopped and I should restart it. I need 24/7 working script because the project is in production. So how solve this problem?

Have you tried setting it up using a simple systemd service?

@walkor So what problem is here?

Apr 05 '19 04:04 alikenski

But today I have noticed that PHPSocket.io script is stopped

How do you judge that the PHPSocket.io script is stopped? You mean the process gone away？

Apr 05 '19 10:04 walkor

@walkor Look i will explain the situation. Yesterday at 9:00 in the morning i started phpsocket.io as a deamon. command php server.php start -d

By the documentation script should work 24/7 without stopping.

But today in the morning at 8:50 i have noticed that phpsocket.io is stopped. Because in the browser console i saw socket.io.js:2925 GET http://[SERVER_IP]:3001/socket.io/?EIO=3&transport=polling&t=1554462163163-1 net::ERR_CONNECTION_REFUSED. I go to the server console and wrote the command php server.php status and see this:

Workerman[server.php] status
Workerman[server.php] not run

So, why phpsocket.io stops every night if started as a deamon?

Apr 05 '19 11:04 alikenski

Run command nohup strace -ttp pid -o /tmp/strace.log &. Pid is the master pid of phpsocket.io which can be found by command ps auxf. Do not run restart or stop command until the problem happens again. Then show me the /tmp/strace.log.

This is the output in the terminal. There i took 435501 .

I have some problem with this comand nohup strace -ttp 435501 -o /tmp/strace.log. When i start this command in console i have error message nohup: ignoring input and appending output to 'nohup.out'. Please help me

Apr 10 '19 12:04 alikenski

nohup: ignoring input and appending output to 'nohup.out'. is not error message, but just a tips which you can ignore. And the command should be nohup strace -ttp 435500 -o /tmp/strace.log & , do not forget &. Pid is master process pid which is 435500 not 435501 in your case.

cd your project and show the outputs for command grep daemonize ./ -Rn.

@walkor Good day mister Walkor. The script stops when nobody use the website. Maybe PHPSocket.io will work when at least one web browser is connected?

May 23 '19 06:05 alikenski

Daemon mode does not require browser connections. Nobody has post similar issue at the moment. I think it's probably because your PHP uses some extension not stable that causes this problem.

Can you try another machine and php version?

May 23 '19 09:05 walkor

@walkor Sorry but no. It is our company's server. Now i have one idea it is run command php server.php start -d via Cron. I have tried it but the error message was only run in command line mode . Do you have any idea to solve this?

May 23 '19 09:05 alikenski

Try command nohup php server.php start & . with out -d but &. This command can also run server.php as daemon mode. No need to use cron.

May 24 '19 01:05 walkor

I solved the problem taking out the permanent PDO connection inside the server.

Before, I was starting a PDO connection together with the socket server, without close. I changed it to open and close the PDO connections only where I really need to use it.

The real problem: MySql server close instantly all long connections, and this exception cause failures on socket server
