In order to setup manually you can login with root user or any user with which you want your nginx to run . Create a file nginx.repo in following directory .

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

lets add the centos 7 repository below , if you have Centos7 Server.

Installing Nginx On Centos7

Once we have the repository added we can now install nginx using below command

sudo yum install nginx

Nginx will now get installed on your VPS or Server. Next step is verify installation.

Verify Nginx Installation

Now we have installed nginx , next step is to verify if the installation actually works .Let's follow the steps below.

sudo systemctl enable nginx
sudo systemctl start nginx

Above command will register nginx as a systemd service and now we can actually check the status of our service.

sudo systemctl status nginx

OutPut : nginx status active

Now that your nginx service is up and running , you should be able access it .Although you won't be able to acess it through an IP . let's check few of the configurations if you want nginx access via IP Address.

Setup Firewalld for Nginx

Why do we need to update firewalld configurations ? One of the reason is that your centos7 server will by default block all incoming web traffic due to security reasons .

Firewalld configuration changes to allow HTTP and HTTPS web traffic should be done as using below commands.

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

Now that you have executed all the above commands successfully , you will be now able to access your Centos7 Nginx home page using your IPAddress.


you should be able to now see the nginx home page . nginx welcome page

Nginx Configurations to Remember

  1. /etc/nginx/nginx.conf is the main configuration file for nginx.
  2. In case of an error , navigate to nginx log files inside /var/log/nginx . You will find two log files error.log and access.log .
  3. Put all your domains under /etc/nginx/conf.d create a separate domain.conf files for all te domain you want to have in your nginx .


Congratulations ! We have installed nginx now successfully . You can host multiple sites in nginx and you can also point your node ,springboot servers using server blocks.
