Start Nginx Service Centos 7
Before You Start: Server and Requirements
If you are running a website or a web application on Centos 7, chances are you will be using Nginx – a robust, high-performance web server that has become the de facto standard in the hosting world. It is well-suited for both static and dynamic content and offers a wide range of features, such as load balancing, reverse proxying, URL rewriting, header manipulation, and more. However, before you can start using Nginx on your Centos 7 server, there are a few prerequisites.
The first and most important requirement is that you have a server running Centos 7 with root access. This means that you should be logged in as the root user, or you should have access to the root user. This is necessary in order to install and configure Nginx.
You will also need to ensure that your server is updated to the latest version of Centos. This can be done with the yum package manager, as is explained in this article.
Installing Nginx
Once you have taken care of the prerequisites, you can begin the process of installing Nginx on your server. Nginx is offered through the official Centos 7 repository. This makes it easy to install from the command line using the yum package manager. To install Nginx, open a terminal and enter the following command:
$ sudo yum install nginx
This will install Nginx and all the necessary files. After the installation is complete, you should see a message stating that the package was installed successfully.
Starting Nginx Service
Once Nginx has been installed, you will need to start the service. To do this, enter this command:
$ sudo systemctl start nginx
This will start the Nginx service. After the service has been started, you will need to verify that it is running properly. To do this, enter the following command:
$ sudo systemctl status nginx
This should show that the Nginx service is running. If it is not, then you will need to investigate further.
Configure the Firewall for Nginx
Now that you have the Nginx service running, you will need to configure the firewall so that it allows traffic to pass through. To do this, you will need to open the ports that Nginx is listening on. To open port 80 (which is used for HTTP traffic), enter the following command:
$ sudo firewall-cmd --permanent --add-port=80/tcp
This will open port 80. To open port 443 (which is used for secure HTTPS traffic), enter the following command:
$ sudo firewall-cmd --permanent --add-port=443/tcp
Once you have opened the necessary ports, you will need to reload the firewall using this command:
$ sudo firewall-cmd --reload
Verify Nginx Installation
At this point, Nginx should be up and running on your server. To verify the installation, open a web browser and navigate to http://your-server-ip. You should see a page that says “Welcome to Nginx”. If you do not see this page, then there is some problem with your configuration and you will need to investigate further.
Create a Basic Website
Now that you have Nginx running, you can begin to create a basic website. In this example, we will assume that your domain name is example.com. To create the basic website, you will need to create a server block in your Nginx configuration file. To do this, open your Nginx configuration file with your text editor:
$ sudo vi /etc/nginx/nginx.conf
You should see a file that looks something like this:
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
server_name _;
location / {
try_files $uri $uri/ =404;
}
}
What you need to do is create a new server block for your website, like this:
server {
listen 80;
server_name example.com www.example.com;
root /var/www/example.com;
index index.html index.htm index.nginx-debian.html;
location / {
try_files $uri $uri/ =404;
}
}
This block will allow Nginx to serve requests for the example.com domain. Save the file and reload Nginx with the following command:
$ sudo systemctl reload nginx
Now, create an index page by creating a file in the /var/www/example.com directory. Enter the following text into the index page:
Welcome to Example.com!
This is the home page for the example.com website.
Save the file and test your new website by navigating to http://example.com. You should see a page that says “Welcome to Example.com!”.
