Celeryd multi 与 supervisord

Question

正在尝试运行 supervisord (3.2.2) with celery multi。

好像是supervisord处理不了。单身芹菜工人工作正常。

这是我的supervisord配置

celery multi v3.1.20 (Cipater)
> Starting nodes...
    > celery1@parzee-dev-app-sfo1: OK
Stale pidfile exists. Removing it.
    > celery2@parzee-dev-app-sfo1: OK
Stale pidfile exists. Removing it.

celeryd.conf

; ==================================
;  celery worker supervisor example
; ==================================

[program:celery]
; Set full path to celery program if using virtualenv
command=/usr/local/src/imbue/application/imbue/supervisorctl/celeryd/celeryd.sh
process_name = %(program_name)s%(process_num)d@%(host_node_name)s
directory=/usr/local/src/imbue/application/imbue/conf/
numprocs=2
stderr_logfile=/usr/local/src/imbue/application/imbue/log/celeryd.err
logfile=/usr/local/src/imbue/application/imbue/log/celeryd.log
stdout_logfile_backups = 10
stderr_logfile_backups = 10
stdout_logfile_maxbytes = 50MB
stderr_logfile_maxbytes = 50MB
autostart=true
autorestart=false
startsecs=10

我使用以下监督变量来模拟我启动 celery 的方式：

%(program_name)s
%(process_num)d
@
%(host_node_name)s

主管

supervisorctl 
celery:celery1@parzee-dev-app-sfo1   FATAL     Exited too quickly (process log may have details)
celery:celery2@parzee-dev-app-sfo1   FATAL     Exited too quickly (process log may have details)

我尝试在 /usr/local/lib/python2.7/dist-packages/supervisor/options.py from 0 to 1:

中更改此值

numprocs_start = integer(get(section, 'numprocs_start', 1))

我仍然得到：

celery:celery1@parzee-dev-app-sfo1   FATAL     Exited too quickly (process log may have details)
celery:celery2@parzee-dev-app-sfo1   EXITED    May 14 12:47 AM

Celery 正在启动，但 supervisord 没有跟踪它。

root@parzee-dev-app-sfo1:/etc/supervisor#

ps -ef | grep celery

celery.sh

source ~/.profile
CELERY_LOGFILE=/usr/local/src/imbue/application/imbue/log/celeryd.log
CELERYD_OPTS=" --loglevel=DEBUG"
CELERY_WORKERS=2
CELERY_PROCESSES=16
cd /usr/local/src/imbue/application/imbue/conf
exec celery multi start $CELERY_WORKERS -P processes -c $CELERY_PROCESSES -n celeryd@{HOSTNAME} -f $CELERY_LOGFILE $CELERYD_OPTS

由于主管监视(start/stop/restart)进程，进程应该运行在前台(不应该被守护进程)。

Celery multi 守护进程本身，所以它不能运行与主管。

您可以为每个工作人员创建单独的进程并将它们组合为一个。

[program:worker1]
command=celery worker -l info -n worker1

[program:worker2]
command=celery worker -l info -n worker2

[group:workers]
programs=worker1,worker2

您也可以编写一个 shell 脚本，makes daemon process run in foreground 像这样。

#! /usr/bin/env bash
set -eu

pidfile="/var/run/your-daemon.pid"
command=/usr/sbin/your-daemon

# Proxy signals
function kill_app(){
    kill $(cat $pidfile)
    exit 0 # exit okay
}
trap "kill_app" SIGINT SIGTERM

# Launch daemon
$ celery multi start 2 -l INFO

sleep 2

# Loop while the pidfile and the process exist
while [ -f $pidfile ] && kill -0 $(cat $pidfile) ; do
    sleep 0.5
done
exit 1000 # exit unexpected
