How to install the Nginx Mainline version
CentOS
Install the prerequisites:
yum install yum-utils
To set up the yum repository, create the file named /etc/yum.repos.d/nginx.repo with the following contents:
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
By default, the repository for stable Nginx packages is used. To use mainline Nginx packages, run the following command:
yum-config-manager --enable nginx-mainline
To install Nginx, run the following command:
It will be prompted to accept the GPG key, verify that the fingerprint matches 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62, and if so, accept it.
yum install nginx

To make your pages available to the public, you will have to edit your firewall rules to allow HTTP requests on your web server by using the following commands.
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload
Output:

Ubuntu
Install the prerequisites:
apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring
Import an official Nginx signing key so apt could verify the authenticity of the package. Fetch the key:
curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
| sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
Output:
root@vps:~# curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
| sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

Verify that the downloaded file contains the proper key:
gpg --dry-run --quiet --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg
The output should contain the full fingerprint 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 as follows:
Output:

If the fingerprint is different, remove the file.
To use mainline Nginx packages, run the following command:
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
| sudo tee /etc/apt/sources.list.d/nginx.list
Set up repository pinning to prefer our packages over distribution-provided ones:
echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
| sudo tee /etc/apt/preferences.d/99nginx
Output:
Package: *
Pin: origin nginx.org
Pin: release o=nginx
Pin-Priority: 900
To install Nginx, run the following commands:
apt update
apt install nginx
Once Nginx is successfully installed, you can start and verify it by running
systemctl start nginx
systemctl status nginx
Output:
