supervisor线上部署uwsgi（不支持多线程）/gunicorn（支持多线程）
supervisor主要功能： 批量管理、批量启停进程
1. 安装
yum install supervisor -y
pip install gunicorn
2. 生成supervisor配置文件
echo_supervisord_conf > /etc/supervisord.conf 必须在/etc目录下
3. 编辑配置文件
-
/etc/supervisord.conf （启动文件可以是别的路径，但这个文件也要跟启动文件内容一样，否则启动不了，暂不知道原因，欢迎在评论区补充）

; 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.

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.

- 配置gunicorn（支持多线程）进程
同supervisord.conf目录创建项目配置文件：project_name.ini（project_name不固定）
[program:projectName]
#启动命令，-w worker 建议2*核数
command=/usr/local/pythonEnvs/django/bin/gunicorn -w 8 二层项目名称.asgi:application -k uvicorn.workers.UvicornWorker --access-logfile '/usr/local/项目名称/二层项目名称/logs/manage.log' -b 0.0.0.0:port

stopasgroup=true
# 默认false，向进程组发送kill信号，包括子进程
killasgroup=true
# 优先级，值小的优先启动
priority=997
4. 启动
supervisord -c /etc/supervisord.conf # 指定文件启动supervisor，配置文件可为其他路径
supervisorctl # 可查看supervisor正在守候的进程（如果是pip install安装的supervisor，可能需要supervisorctl -c /etc/supervisord.conf进入）
5. 其他常用命令
supervisorctl reload # 重启所有程序(restart不会加载新配置，reload可以)
supervisorctl update # 重启更改了配置的程序（未更改配置的程序不受影响）
supervisorctl start/stop/restart program_name # 启动/停止/重启某个进程(program_name=你配置中写的程序名称)
supervisorctl start/stop all # 开启/停止全部进程
注意：已经stop的进程，使用reload或update都不会自动重启
6. 开机自启
systemctl enable supervisord
如果报错，考虑先创建supervisor.service的系统服务（一般是pip安装的需要）
7. 坑
配置中不能用“;”冒号进行注释，使用时注意去掉，不知道为什么。
