nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server, originally written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, Mail.Ru, VK, and Rambler. According to Netcraft, Nginx served or proxied 22.36% of the busiest sites in November 2021. Here are some of the success stories: DropboxNetflixWordPress.comFastMail.FM.

The initial step to upgrade Nginx is taking a backup of your current configuration.

$ sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.backup

Next, we will need to Install the software-properties-common dependencies to add the repository

$ sudo apt-get install software-properties-common

Once the above dependency is installed add the repository for the stable version of the Nginx

$ sudo add-apt-repository ppa:nginx/stable

Now update the changes using the below command

$ sudo apt-get update

Run the below command to install

$ sudo apt-get install nginx

When it asks you if you want to keep using the old config or get the new config like as shown below

Configuration file '/etc/nginx/nginx.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** nginx.conf (Y/I/N/O/D/Z) [default=N] ?

Select N(No). It will Install the new version of the current config files in  the directory.


Select Y(es) and get the latest config. It will remove current config files.

Now how do we check/validate the version upgrade is successful?

Run the below command to check the version

$ nginx -v

Following will be the output on your console.

nginx version: nginx/1.18.0 (Ubuntu)
