NGINX installation

To install NGINX follow this step by step instructions below:

• Add EPEL Repository. To add the CentOS 7 EPEL repository, open terminal and use the following command:

sudo yum install epel-release

• Install Nginx:

sudo yum install nginx

• If you are running a firewall, run the following commands to allow HTTP and HTTPS traffic:

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

• To create configuration file run:

sudo vim /etc/nginx/conf.d/domain.conf

• And copy below configuation into it:

YOUR_DOMAIN_NAME - replace with your domain name
CERTIFICATE_PATH - replace with your certificate location
PRIVATE_KEY_PATH - replace with your private key location

server {
    listen 80;
    server_name YOUR_DOMAIN_NAME;
    return 301 https://$host$request_uri;
}

server {
    server_name YOUR_DOMAIN_NAME_HERE;
    listen 443 ssl;
    client_max_body_size 200M;

    ssl on;
    ssl_certificate         CERTIFICATE_PATH;
    ssl_certificate_key     PRIVATE_KEY_PATH;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    ssl_ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header    Host              $host;
        proxy_set_header    X-Real-IP         $remote_addr;
        proxy_set_header    X-Forwarded-For   $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto $scheme;
        proxy_http_version   1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection "upgrade";
    }

    location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|js|woff2|ttf|woff|eot|svg)$ {
        proxy_pass http://localhost:8080;
        access_log off;
        expires 1y;
    }
}

• Start Nginx service:

sudo systemctl start nginx

• You can do a spot check right away to verify that everything went as planned by visiting your server's public IP address in your web browser:

https://server_domain_name/

• Enable Nginx service to start when your system boots:

sudo systemctl enable nginx
