[英]Supervisor - Start a django app and keep it running via bash file
我基本上是按照標題所說的去做-即使在服務器重啟時,也要保持django應用程序運行。
我遵循了一些教程,但沒有成功地獲得監督以替我完成此任務。
我目前在/etc/supervisor/conf.d
有一個名為MyConf.conf
的conf
,看起來像:
[program:MyConf]
command = /home/user/virtualenv/gunicorn_start.bash ; Command to start app
autostart=true ; start app when system starts
autorestart=true ; defines how app starts in event app exits
user=vanew ; User to run as
stdout_logfile=/home/user/virtualenv/nginxConfiguration/error/gunicorn_supervisor.log ; Where to write log messages
stderr_logfile=/home/user/virtualenv/nginxConfiguration/error/gunicorn_supervisor_error.log ; Where to write log error messages
redirect_stderr = true
gunicorn_start.bash
#!/bin/bash
NAME="myapp" # Name of the application
DJANGODIR=/home/useros/virtualenv/MyConf/myapp # Django project directory
#SOCKFILE=/webapps/hello_django/run/gunicorn.sock # we will communicte using this unix socket
USER=user # the user to run as
GROUP=user # the group to run as
NUM_WORKERS=5 # how many worker processes should Gunicorn
DJANGO_SETTINGS_MODULE=MyConf.settings # which settings file should Django use
DJANGO_WSGI_MODULE=MyConf.wsgi # WSGI module name
echo "Starting $NAME"
# Activate the virtual environment
cd $DJANGODIR
source ../../bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH
# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR
# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use --daemon)
exec /usr/local/bin/gunicorn ${DJANGO_WSGI_MODULE}:application \
--name $NAME \
--workers $NUM_WORKERS \
--user=$USER --group=$GROUP \
--log-level=debug \
--bind=unix:$SOCKFILE
當我運行以下命令時,它的stdout_logfile
文件中始終給我以下錯誤: sudo supervisorctl start MyConf
:
Starting myapp
dirname: missing operand
Try 'dirname --help' for more information.

注意: gunicorn_start.bash
已通過chmod +x gunicorn_start.bash
可執行文件chmod +x gunicorn_start.bash
顯然,它找不到文件或目錄,是因為什么? 我怎樣才能解決這個問題?
為什么不只使用超級用戶配置來設置所有內容? 似乎在您的主管conf中缺少directory
值:
[program:gunicorn]
directory=/home/useros/virtualenv/MyConf
command=/home/useros/virtualenvs/MyConf/bin/python manage.py run_gunicorn -b unix:/tmp/gunicorn.sock
numprocs=4
user=vanew
autostart=true
autorestart=true
process_name=%(program_name)s_%(process_num)s
stdout_logfile=/var/log/supervisor/%(program_name)s_%(process_num)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s_%(process_num)s.err
