使用supervisor 部署 Django celery
yum安装supervisord
yum install -y epel-release
yum install -y supervisor
systemctl enable supervisord # 开机自启动
systemctl start supervisord # 启动supervisord服务
systemctl status supervisord # 查看supervisord服务状态
ps -uax | grep supervisord # 查看是否存在supervisord进程
supervisord -c /usr/local/logstash/config/supervisord.conf
1 安装环境包
pip3.6 install -r plist.txt --default-timeout=1000 --no-cache-dir -i https://mirrors.aliyun.com/pypi/simple/
pip3.6 install supervisor
2 创建文件夹 与manage.py同级
mkdir conf
cd conf
touch supervisord.conf # 新建文件
echo_supervisord_conf > supervisord.conf # 初始化配置文件
3 修改supervisord.conf
; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
; - Shell expansion ("~" or "$HOME") is not supported. Environment
; variables can be expanded using this syntax: "%(ENV_HOME)s".
; - Quotes around values are not supported, except in the case of
; the environment= options as shown below.
; - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
; - Command will be truncated if it looks like a config file comment, e.g.
; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
;
; Warning:
; Paths throughout this example file use /tmp because it is available on most
; systems. You will likely need to change these to locations more appropriate
; for your system. Some systems periodically delete older files in /tmp.
; Notably, if the socket file defined in the [unix_http_server] section below
; is deleted, supervisorctl will be unable to connect to supervisord.
[unix_http_server]
file=/tmp/supervisor.sock ; UNIX socket 文件，supervisorctl 会使用
;chmod=0700 ; socket文件的mode，默认是0700
;chown=nobody:nogroup ; socket文件的owner，格式：uid:gid
;username=user ; default is no username (open server)
;password=123 ; default is no password (open server)
; Security Warning:
; The inet HTTP server is not enabled by default. The inet HTTP server is
; enabled by uncommenting the [inet_http_server] section below. The inet
; HTTP server is intended for use within a trusted environment only. It
; should only be bound to localhost or only accessible from within an
; isolated, trusted network. The inet HTTP server does not support any
; form of encryption. The inet HTTP server does not use authentication
; by default (see the username= and password= options to add authentication).
; Never expose the inet HTTP server to the public internet.
[inet_http_server] ; HTTP服务器，提供web管理界面
port=0.0.0.0:9001 ; Web管理后台运行的IP和端口，如果开放到公网，需要注意安全性

4 新建supervisord_celery_worker.ini文件
[program:game_celery_worker]
# 程序启动命令
command=/usr/bin/python3.6 manage.py celery worker -l INFO
# 命令执行的目录
directory=/root/01-yu/03-django/spider_user
# 添加环境变量
# environment=PATH="/home/pyvip/.virtualenvs/Cel_proj/bin",B="2"
# 输出日志文件

# 输入日志文件大小 默认是50MB
stdout_logfile_maxbytes=50MB
# 输入日志文件发备份 (0-不备份 默认是10)
stdout_logfile_backups=10
# capturemode 字节数 默认是10
stdout_capture_maxbytes=10MB ; number of bytes in 'capturemode' (default 0)
# 突发事件写入 stfout中 默认是false
stdout_events_enabled=false
# 错误日志文件
stderr_logfile=/root/01-yu/03-django/spider_user/apps/log/celery_worker_err.log
# 输入日志文件大小 默认是50MB
stderr_logfile_maxbytes=50MB
# 输入日志文件发备份 (0-不备份 默认是10)
stderr_logfile_backups=10

startsecs=10
# 等待最长时间 默认是10s
stopwaitsecs=600

redirect_stderr=true
# 默认为false,进程被杀死时，是否向这个进程组发送stop信号，包括子进程

killasgroup=false
4 启动supervisord
supervisord -c /root/01-yu/03-django/spider_user/conf/supervisord.conf # 启动
supervisorctl shut # 关闭
5 报错
Unlinking stale socket /tmp/supervisor.sock
解决办法 rm -rf /tmp/supervisor.sock
6 交互终端
supervisord启动成功后，可以通过supervisorctl客户端控制进程，启动、停止、重启。运行supervisorctl命令，不加参数，会进入supervisor客户端的交互终端，并会列出当前所管理的所有进程。
supervisorctl -c /root/01-yu/03-django/spider_user/conf/supervisord.conf # 输入前面conf文件配置的账号密码
7.supervisorctl常用命令
supervisorctl stop program_name # 停止某一个进程，program_name 为 [program:x] 里的 x
supervisorctl start program_name # 启动某个进程
supervisorctl restart program_name # 重启某个进程
supervisorctl stop groupworker: # 结束所有属于名为 groupworker 这个分组的进程 (start，restart 同理)
supervisorctl stop groupworker:name1 # 结束 groupworker:name1 这个进程 (start，restart 同理)
supervisorctl stop all # 停止全部进程，注：start、restartUnlinking stale socket /tmp/supervisor.sock、stop 都不会载入最新的配置文件
supervisorctl reload # 载入最新的配置文件，停止原有进程并按新的配置启动、管理所有进程
supervisorctl update # 根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启
8.Web管理界面
