There is no doubt that NGINX is the easiest and the fastest open source web server out there in the market right now. Let’s look into some basic Linux Ubuntu command line commands.
The command to a switch user (in this case Smith):
$ su - smith
List of all users with a home directory
$ cat /etc/passwd | grep /home | cut -d: -f1
List of all users with or without a home directory
$ compgen -u
Change password (user is username)
$ passwd user
Code for 302 Redirection in NGINX Config file location = /blog/what-is-seo-uses-of-seo/ { return 302 /blog/how-seo-can-make-a-difference; }
The actual web content, which by default only consists of the default Nginx page, is served out of the /var/www/html directory. This can be changed by altering Nginx configuration files.
$ cd /var/www/html
The Nginx configuration directory. All of the Nginx configuration files reside here:
$ cd /etc/nginx
The main Nginx configuration file. This can be modified to make changes to the Nginx global configuration.
$ cd /etc/nginx/nginx.conf
The directory where per-site “server blocks” can be stored. Nginx will not use the configuration files found in this directory unless they are linked to the sites-enabled directory (see below).
Typically, all server block configuration is done in this directory, and then enabled by linking to the other directory
$ cd /etc/nginx/sites-available/
The directory where enabled per-site “server blocks” are stored.
Typically, these are created by linking to configuration files found in the sites-available directory
$ cd /etc/nginx/sites-enabled/
This directory contains configuration fragments that can be included elsewhere in the Nginx configuration. Potentially repeatable configuration segments are good candidates for refactoring into snippets
$ cd /etc/nginx/snippets
Every request to your web server is recorded in this log file unless Nginx is configured to do otherwise
$ cd /var/log/nginx/access.log
Any Nginx errors will be recorded in the log
$ cd /var/log/nginx/error.log
Reboot ubuntu
sudo reboot
Linux CPU speed test score

$ crontab -e
It may be noted that Atom is the best editor to edit shell session files like conf files, while putty or Chrome SSH extensions can be used to access shell session.
