This is my yum.conf:
[root@localhost etc]# cat yum.conf

gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
best=True
I tried to re-install epel-release:

I hope it helps you.
I am trying to install Nginx using Yum.
Instructions for installing Nginx can be found in the Download section of the NGINX official website.
In the middle, you need to change the ‘OS’ and ‘OSRELEASE’ items to suit your OS.
I am installing in CentOS 7.0, so I set it as below.
Next step
Open the web server port in the firewall.
Run Nginx and change it to start automatically at boot time.
Source: http://blog.tjsrms.me/centos-7-nginx-%EC%84%A4%EC%B9%98%ED%95%98%EA%B8%B0/
You can find the below information useful to install the Nginx web server. But, Nginx is not available in CentOS 8 default repository. So, follow the below steps. And please let me know if it works for you or not.
Step 1: Installation of EPEL repository
You have to install the
EPEL(Extra Package for Enterprise Linux) repository on your server. It is a free repository and allows you to connect many other open-source software packages. Use the below command to installEPEL.Press
yto accept the installation confirmation and press theEnterkey.After completing the EPEL installation, run the below command to view the available Nginx versions.
Step 2: Enabling the latest Nginx web server module
After that, you have to enable the latest Nginx module. In other words, you have to tell the dnf command to install the newest version. So, use the below command for this purpose.
For instance, The available version of
Nginxright now is in EPEL repository1.8.Step 3: Install Nginx web server
So, we have already installed the EPEL repository. As a result, we can install it directly using dnf command. Use the below command to install the latest version of Nginx.
Step 4: Starting and enabling the Nginx service daemon
Use the below command, which will start the service immediately, and also it will enable the service on boot.
Step 5: Checking the Nginx service status
Step 6: Configuration of the firewall to allow the Nginx traffic
You can run the below command to add HTTP and https service permanently in the firewall.
After allowing the service, we need to reload the firewall service daemon.
Step 7: Checking the Nginx web server
Now, you can test your Nginx web server that if it is up and running or not by accessing the public IP of your server or domain name from your web browser.
http://domain_name_or_IP
For Instance, if the IP address of the server is 192.168.43.164. So, the link will look like
http://192.168.43.164That’s it about NGINX web server installation.
But, if you like to get a few extra details, then You can find a complete example on my blog:
