How to install and configure the supervisor daemon under centos7

Newbie, record it yourself

1. Install supervisor. Supervisor is developed based on Python. When you install Supervisor, Python dependencies are automatically installed, so no additional installation is required.

# yun install supervisor

2. After successful installation, check the relevant files and directories generated under /etc

supervisord.conf is the default configuration file

supervisord.d is the directory where separate configuration files for other programs are stored

3. Configure supervisord.conf

For all parameters, please refer to the official documentation. There are too many configuration items for us to understand. We only need to modify one place and keep the others unchanged.

# vim /etc/supervisord.conf

Locate the last [include] item in the document and change files = supervisord.d/*.ini to files = supervisord.d/*.conf to load the configuration of other applications.

4. Add a separate configuration file for the application (dotnet core)

Create a new configuration file in the supervisord.d directory

# touch /etc/supervisord.d/FirstApi.conf

Open the file and add the following content

[program:FirstApi]
#Command to execute command=dotnet FirstApi.dll
#Command execution directory directory=/home/www/first
#Environment variable environment=ASPNETCORE__ENVIRONMENT=Production
#Process execution user identity<br> user=root<br> stopsignal=INT
#Whether to start automatically autostart=true
#Whether to automatically restart autorestart=true
#Automatic restart interval seconds startsecs=1
#Standard error log stderr_logfile=/var/log/FirstApi.err.log
#Standard output log stdout_logfile=/var/log/FirstApi.out.log

5. Restart the supervisor service

# supervisord -c /etc/supervisord.conf

If the prompt "Another program is already listening on a port that one of our HTTP servers" appears, it means that the service is already running. You can restart the service by following the steps below.

#Enter the console# supervisorctl
#Reread the configuration
#Update configuration update
#Start all configurations start all
#Check the status after success 

At this time, visit the program address again and find that the project has run successfully!
