Installation instructions depend whether the system on which you’re attempting to install Supervisor has internet access.
If your system has internet access, you can get Supervisor installed in two ways:
If the Python interpreter you’re using has Setuptools installed, and the system has internet access, you can download and install supervisor in one step using easy_install.
Depending on the permissions of your system’s Python, you might need to be the root user to install Supervisor successfully using easy_install.
If your system does not have setuptools installed, you will need to download the Supervisor distribution and install it by hand. Current and previous Supervisor releases may be downloaded from PyPi. After unpacking the software archive, run python setup.py install. This requires internet access. It will download and install all distributions depended upon by Supervisor and finally install Supervisor itself.
Depending on the permissions of your system’s Python, you might need to be the root user to sucessfully invoke python setup.py install.
If the system that you want to install Supervisor to does not have Internet access, you’ll need to perform installation slightly differently. Since both easy_install and python setup.py install depend on internet access to perform downloads of dependent software, neither will work on machines without internet access until dependencies are installed. To install to a machine which is not internet-connected, obtain the following dependencies on a machine which is internet-connected:
Copy these files to removable media and put them on the target machine. Install each onto the target machine as per its instructions. This typically just means unpacking each file and invoking python setup.py install in the unpacked directory. Finally, run supervisor’s python setup.py install.
Depending on the permissions of your system’s Python, you might need to be the root user to invoke python setup.py install sucessfully for each package.
Some Linux distributions offer a version of Supervisor that is installable through the system package manager. These packages may include distribution-specific changes to Supervisor.
Some of these packages can lag considerably behind the official release version. For example, Ubuntu 12.04 (released April 2012) offers a package based on Supervisor 3.0a8 (released January 2010).
Use the package management tools of your distribution to check availability; e.g. on Ubuntu you can run apt-cache show supervisor, and on CentOS you can run yum info supervisor.
Packaged Supervisor will normally already be integrated into the service management infrastructure of your distribution.
With pip >= 1.4
pip install supervisor --pre
With previous versions of pip:
pip install supervisor
Once the Supervisor installation has completed, run echo_supervisord_conf. This will print a “sample” Supervisor configuration file to your terminal’s stdout.
Once you see the file echoed to your terminal, reinvoke the command as echo_supervisord_conf > /etc/supervisord.conf. This won’t work if you do not have root access.
If you don’t have root access, or you’d rather not put the supervisord.conf file in /etc/supervisord.conf`, you can place it in the current directory (echo_supervisord_conf > supervisord.conf) and start supervisord with the -c flag in order to specify the configuration file location.
For example, supervisord -c supervisord.conf. Using the -c flag actually is redundant in this case, because supervisord searches the current directory for a supervisord.conf before it searches any other locations for the file, but it will work. See Running Supervisor for more information about the -c flag.
Once you have a configuration file on your filesystem, you can begin modifying it to your liking.
