CentOS 中安装 supervisor 4.2.2

因服务器已安装Python 3.8.0，所以直接安装Supervisor 4.2.2

1. 安装
pip install supervisor or pip3 install supervisor

2. 检测是否安装成功
supervisord -v

3. 生成配置文件
　　mkdir -p /etc/supervisor/conf.d
　　echo_supervisord_conf > /etc/supervisor/supervisord.conf
4. 编辑配置文件
　　vim /etc/supervisor/supervisord.conf

[inet_http_server]
port=*:9001
username=admin
password=123456

[include]
files = /etc/supervisor/conf.d/*.conf

5. 单独配置要守护的程序

在 /etc/supervisor/conf.d/ 下创建配置文件 datacheck.conf
[program:datacheck]
command=dotnet datacheck.dll
directory=/var/www/www.datacheck.com/
stderr_logfile=/var/log/datacheck.error.log
stdout_logfile=/var/log/datacheck.stdout.log
environment=ASPNETCORE_ENVIRONMENT=datacheck
user=root
stopsignal=INT
autostart=true
autorestart=true
startsecs=3

6. 启动
supervisord -c /etc/supervisor/supervisord.conf

7. 设置开机启动
