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.

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 stdout_logfile=/root/01-yu/03-django/spider_user/apps/log/celery_worker_info.log # 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 # capturemode 字节数 默认是10 stderr_capture_maxbytes=10MB ; number of bytes in 'capturemode' (default 0) # 突发事件写入 stfout中 默认是false stderr_events_enabled=false # 是否自动启动 autostart=true # 程序意外退出是否自动重启 autorestart=true # 启动10秒后没有异常退出,就表示进程正常启动了,默认为1秒 startsecs=10 # 等待最长时间 默认是10s stopwaitsecs=600 # 进程启动优先级,默认999,值小的优先启动 priority=998 # 进程执行的用户身份 user=root # 启动失败自动重试次数,默认是3 startretries=3 # 把stderr重定向到stdout,默认false 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 stopasgroup=false # 默认为false,向进程组发送kill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
