Answer 2

对于那些仍在寻找这个答案的人。

在 AWS 中，您可以使用 elasticache(Redis)，将此 Redis 集群与您的 EC2 实例连接，并从仪表板获取集群的主要端点。
现在通过 SSH 密钥登录您的 ec2（使用 putty 或 mobaXterm）。
现在在您的服务器上安装 Redis（无论您使用什么）
安装后：
输入 redis-server 它应该输出 ok
然后输入 redis-cli -h <your redis cluster endpoint(assuming default port 6379)
现在测试它 PING 它应该打印 PONG

现在redis部分完成了对于 Celery，考虑到您正在使用 django

导航到您服务器中的此 /etc/supervisor/conf.d/ 目录

创建 celery.conf 文件（你可以随意命名）并输入这个

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

; the name of your supervisord program
[program:myprojectcelery]

; Set full path to celery program if using virtualenv
command=/home/ubuntu/.virtualenvs/myproject/bin/celery worker -A picha --loglevel=INFO

; The directory to your Django project
directory=/home/ubuntu/myproject

; If supervisord is run as the root user, switch users to this UNIX user account
; before doing any processing.
user=ubuntu(use your root user)

; Supervisor will start as many instances of this program as named by numprocs
numprocs=1

; Put process stdout output in this file
stdout_logfile=/var/log/celery/whatever_worker.log

; Put process stderr output in this file
stderr_logfile=/var/log/celery/whatever_worker.log

; If true, this program will start automatically when supervisord is started
autostart=true

; May be one of false, unexpected, or true. If false, the process will never
; be autorestarted. If unexpected, the process will be restart when the program
; exits with an exit code that is not one of the exit codes associated with this
; process’ configuration (see exitcodes). If true, the process will be
; unconditionally restarted when it exits, without regard to its exit code.
autorestart=true

; The total number of seconds which the program needs to stay running after
; a startup to consider the start successful.
startsecs=10

; Need to wait for currently executing tasks to finish at shutdown.
; Increase this if you have very long running tasks.
stopwaitsecs = 600

; When resorting to send SIGKILL to the program to terminate it
; send SIGKILL to its whole process group instead,
; taking care of its children as well.
killasgroup=true

; if your broker is supervised, set its priority higher
; so it starts first
priority=998

创建另一个文件 celerybeat.conf 并输入

;  celery beat supervisor example
; ================================

; the name of your supervisord program
[program:celerybeat]

; Set full path to celery program if using virtualenv
command=/home/ubuntu/.virtualenvs/myproject/bin/celerybeat -A picha --loglevel=INFO

; The directory to your Django project
directory=/home/ubuntu/myproject

; If supervisord is run as the root user, switch users to this UNIX user account
; before doing any processing.
user=mosh

; Supervisor will start as many instances of this program as named by numprocs
numprocs=1

; Put process stdout output in this file
stdout_logfile=/var/log/celery/whatever_beat.log

; Put process stderr output in this file
stderr_logfile=/var/log/celery/whatever_beat.log

; If true, this program will start automatically when supervisord is started
autostart=true

; May be one of false, unexpected, or true. If false, the process will never
; be autorestarted. If unexpected, the process will be restart when the program
; exits with an exit code that is not one of the exit codes associated with this
; process’ configuration (see exitcodes). If true, the process will be
; unconditionally restarted when it exits, without regard to its exit code.
autorestart=true

; The total number of seconds which the program needs to stay running after
; a startup to consider the start successful.
startsecs=10

; if your broker is supervised, set its priority higher
; so it starts first
priority=999

创建上面代码中提到的日志文件

$ sudo touch /var/log/celery/whatever_beat.log

现在让您的主管了解这些文件
```
$ sudo supervisorctl update
```

现在相应地使用这些命令

$ sudo supervisorctl start myprojectcelery
$ sudo supervisorctl status myprojectcelery
