Install and configure supervisord on centos 7 to run Laravel queues permanently

Question

I want to use Laravel queue system in my project and I want to run php artisan queue:work permanently on server's background, I did some searches about this and I found a command line which can run it even after quit from ssh terminal but It can be down in some cases and can make terrible problems for me. So after a while I found out that there is a package named Supervisord which can restart command even after server is rebooted. So I want to ask someone to help from 0 to 100 step by step how to install Supervisord and configure it on centos 7 and after that set the queue command line. Thank you so much..

Answer 1

here is how to install and config supervisord on centos 7 to run Laravel queues permanently:

1. easy_install supervisor
2. yum install supervisor
3. vim /etc/supervisord.conf edit section program as following:

[program:laravel-worker]
command=php /path/to/app.com/artisan queue:work 
process_name=%(program_name)s_%(process_num)02d
numprocs=8 
priority=999 
autostart=true
autorestart=true  
startsecs=1
startretries=3
user=apache
redirect_stderr=true
stdout_logfile=/path/to/log/worker.log

4. systemctl enable supervisord to autorun at start
5. systemctl restart supervisord to restart the service

Answer 2

Hopefully this will be of use to someone, this is the process I have been through in addition to @Abdu's answer to get things working on CentOS 7.

1. Install Supervisor

easy_install supervisor

* If not installed, run yum install -y python-setuptools and then easy_install supervisor

2. Prep work

To get the ideal setup running, you should run the following...

# create directory for supervisor logs
mkdir /var/log/supervisor

# create directory for supervisor configs
mkdir -p /etc/supervisor/conf.d

# create config directory for supervisor
cat <<EOT >> /etc/supervisor/supervisord.conf
; supervisor config file

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

[include]
files = /etc/supervisor/conf.d/*.conf
EOT

# create systemctl service script
cat <<EOT >> /lib/systemd/system/supervisord.service
[Unit]
Description=Supervisor process control system for UNIX
Documentation=http://supervisord.org
After=network.target

[Service]
ExecStart=/usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown
ExecReload=/usr/bin/supervisorctl -c /etc/supervisor/supervisord.conf $OPTIONS reload
KillMode=process
Restart=on-failure
RestartSec=50s

[Install]
WantedBy=multi-user.target
EOT

Once you've done this, you should now be able to start and stop supervisor using systemctl. To start systemctl, run systemctl start supervisord. To view the status of supervisor, run systemctl status supervisord.

You can create as many custom configurations as you like under /etc/supervisor/conf.d

3. Enable on system startup

You should also enable supervisord on startup by running

systemctl enable supervisord

Answer 3

On my Bluehost account systemctl was not running, but instead chkserv was used to monitor and restart processes, so the two answers here did not fully work for me.

Also, I ran into an error with easy_install supervisor, since it tried to install the new 4.x.x version, which requires Python > 2.6, while 2.6 was the exact version of Python running on my machine.

Here is what worked for me:

1. yum install -y python-setuptools

2. easy_install supervisor==3.4.0

3. nano /etc/supervisord.conf and add

[supervisord]
nodaemon=true

[include]
files = /etc/supervisor/conf.d/*.conf

[program:laravel-worker]
command=php artisan queue:work --tries=1
autostart=true
autorestart=true
stderr_logfile=/var/log/queue.err.log
stdout_logfile=/var/log/queue.out.log

4. nano /etc/chkserv.d/chkservd.conf, add the line supervisord:1, and then save the file

5. touch /etc/chkserv.d/supervisord to create chkservd config file

6. nano /etc/chkserv.d/supervisord, add the line service[supervisord]=x,x,x,service supervisord restart,supervisord,root, and then save the file

7. supervisord will now show up in WHM under Service Manager, and chkservd will start it and make sure it keeps running, but to manually start it, simply run supervisord
