;files = relative/directory/*.ini
files =/etc/supervisor/conf.d/*.ini; 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]

; 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] ; inet (TCP) server disabled by default

启动命令
supervisord -c /etc/supervisor/supervisord.conf
supervisorctl的用法
supervisord : 启动supervisorsupervisorctl reload :修改完配置文件后重新启动supervisorsupervisorctl status :查看supervisor监管的进程状态supervisorctl start all | 进程名 ：启动全部或某进程supervisorctl stop all | 进程名 ：停止全部或某进程supervisorctl stop all：停止进程，注：start、restart、stop都不会载入最新的配置文件。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
linux .netcore 安装
sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
Install the SDK
sudo yum install dotnet-sdk-3.1
Install the runtime
sudo yum install aspnetcore-runtime-3.1
unix:///tmp/supervisor.sock no such file
打开配置文件 ,修改/tmp 路径；要不容易被linux自动清掉 ；
vim /etc/supervisor
/tmp/supervisor.sock -> /var/run/supervisor.sock ;/tmp/supervisord.log -> /var/log/supervisor.log ;/tmp/supervisord.pid -> /var/run/supervisor.pid ;
修改权限
sudo chmod 777 /run
sudo chmod 777 /var/log
创建supervisor.sock
touch /var/run/supervisor.sock
chmod 777 /var/run/supervisor.sock
启动supervisord
ps -ef | grep supervisord
kill -9 15625
supervisord -c /etc/supervisor/supervisord.conf
