  • Installing Nginx Latest on CentOS 7

Nginx isn’t part of CentOS default repositories. You can’t just run yum install nginx and it gets download and installed. In order to get Nginx, you must install and add additional external repositories.

Nginx has its own repositories. Two repositories that are available from Nginx are the stable and mainline repositories. The mainline repository contains features that are new and recently added to Nginx.

The latest version of Nginx is always going to be found in the mainline repository.

The stable repository contains features of Nginx that have been test and proven. All new features are introduced in the mainline repository first, and after thorough testing and validation that they function, they are then move down to the stable repository.

So, if you need to install the latest of Nginx, add its mainline repository. To do that, run the commands below to create a new repository file for Nginx.

sudo vi /etc/yum.repos.d/nginx.repo

Then copy and paste the lines below into the file and save it.

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=0
enabled=1

After that, run the commands below to install Nginx.

sudo yum install nginx

 

  • Allowing HTTP Traffic

By default HTTP traffic is not allowed to CentOS 7. To enable it, open the firewall to allow it through. To do that, run the commands below.

sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

That’s it! You can now go and access the server by browsing to the hostname or IP address.

Enjoy!

If you want Nginx stable version, then here’s the repository for it.

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
