It is written in C, using the Natvie function, which is actually similar to SPAWN-FCGI/PHP-FPM. So UWSGI can support a variety of application frameworks, including (PYTH

want a customized Linux version that can be installed in the rear pocket or in a key ring.
Now, we have a good reason to start some preparation work.
If you are using Windows:
Download Xubuntu.
Download the Universal USB Installer.
Insert an empty USB flash drive.
Use the Universal USB Installer to create a boot disk for the resident system.
If you are using Ubuntu:
Download Xubuntu.
Use Ubuntu Startup Creator.
If you are using another version of Linux:
Download Xubuntu.
Use UNetb
You can also use the crontab command to implement automatic backup:
Sudo/bin/su-root
Crontab-e
Add the following to implement automatic backup at every day:
0 2 ***/usr/bin/gitlab-rake gitlab: backup: create
Gitlab recovery
Likewise, Gitlab's recovery from backup is very simple:
# Stop related data connection services
Gitlab-ctl stop unicorn
Gitlab-ctl stop sidekiq
# Recovering from backup of 1296213186 #
Gitlab-rake gitlab: backup: restore BACKUP =

What are WSGI servers:
For example, Flask, webpy, Django, and CherryPy all carry WSGI servers. Of course, the performance is not good. The built-in web server is mostly used for testing purposes. During online release, the high-performance wsgi server or the uwsgi with nginx is used.
As the WSGI definition says, the Protocol defines a set of interfaces to standardize or unify the communication between the server and the application ). What kind of interface is this? Very simple, especially for
