==> Caveats
To have launchd start supervisor now and restart at login:
  brew services start supervisor
Or, if you don't want/need a background service you can just run:
  supervisord

由此可见，supervisor的主配置文件在/usr/local/etc/supervisord.ini,打开配置文件在最后一行可以修改新增子配置文件，默认在/usr/local/etc/supervisor.d/*.ini。

安装成功后需要启动
手动启动，需要指定主配置文件

supervisord -c /usr/local/etc/supervisord.ini
1
自动随系统启动（推荐）

brew services start supervisor
1
在supervisor安装目录/usr/local/Cellar/supervisor/4.0.4/bin下面有个supervisorctl客户端，supervisorctl用于向supervisord发起命令。

编辑supervisord.ini，将下列注释打开

[inet_http_server] ; inet (TCP) server disabled by default

port=127.0.0.1:9001 ; ip_address:port specifier, *:port for all iface

启动supervisorctl客户端方法：

supervisorctl -c /usr/local/etc/supervisord.ini
1
启动supervisorctl客户端后，可以用浏览器打开进入web界面。

接下来新增子配置，开头已经说过了，子配置文件放在/usr/local/etc/supervisor.d目录下，在该目录下，可以创建多个配置文件指示 Supervisor如何监视进程，例如，让我们创建一个开启并监视 queue:work进程的laravel-worker.ini文件：

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /Applications/MAMP/htdocs/baichuanzhen/artisan queue:work database --sleep=3 --tries=3
autostart=true
autorestart=true
user=forge
numprocs=2
redirect_stderr=true
stdout_logfile=/Applications/MAMP/htdocs/baichuanzhen/storage/logs/queue.log


来看一下supervisorctl有哪些命令

reread ;重新加载配置文件
update ;将配置文件里新增的子进程加入进程组，如果设置了autostart=true则会启动新新增的子进程

status ;查看所有进程状态

status <name> ;查看指定进程状态

start all; 启动所有子进程

start <name>; 启动指定子进程

restart all; 重启所有子进程

restart <name>; 重启指定子进程

stop all; 停止所有子进程
stop <name>; 停止指定子进程

reload ;重启supervisord

add <name>; 添加子进程到进程组

reomve <name>; 从进程组移除子进程，需要先stop。注意：移除后，需要使用reread和update才能重新运行该进程

启动 Supervisor
当成功创建配置文件后，需要刷新 Supervisor 的配置信息并使用如下命令启动进程:

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start laravel-worker:*

然后就成功了。
