Setup Centos 7 Nginx With Php
Overview of Centos7 Nginx and PHP
Centos 7 is one of the most popular operating systems for web servers. Many businesses use Centos 7 for their web servers due to its stability and security. It is well-supported by an active community of developers, sysadmins, and users, making it a convenient and reliable platform to work with.
Nginx is an open source web server and reverse proxy. It is designed to be high-performance, resource-efficient and to handle heavy web traffic. Nginx can also act as a load balancer and is used by many high-traffic websites.
PHP is a widely-used scripting language for web development. It is open source and allows developers to quickly develop dynamic web applications. PHP is compatible with many popular web servers, including Nginx, making it an ideal choice for web development.
In this article, we will go through the process of setting up Nginx and PHP on a Centos 7 server. We will also cover some basic troubleshooting tips to help you get started.
Prerequisites for Setting up Nginx and PHP
Before you get started, there are a few things that you need to take care of. The first step is to make sure your server has an active public IP address. You can assign a static IP address to your server from the command line if one is not already set.
You’ll also need to make sure your server has at least 1GB of RAM and 10GB of disk space. If you are using a cloud-based server, you may want to increase this depending on the size of your app. Lastly, you’ll need to make sure the server is running the latest version of Centos 7.
Step 1: Installing Nginx
The first step is to install Nginx. Luckily, Centos 7 comes with a package manager called Yum, which makes it easy to install software from the command line. To install Nginx, run the following command:
sudo yum install nginx
Nginx will now be installed and ready to be used. Before you can start using it, however, you’ll need to make sure it’s running. To check if it’s running, execute the following command:
sudo systemctl status nginx
If nginx is running, you should see the following output:
active (running) nginx
If nginx isn’t running, you can start it by running the following command:
sudo systemctl start nginx
Step 2: Configuring Nginx
The next step is to configure Nginx. The default configuration files are located in the /etc/nginx/ directory. You can edit these files to customize the server’s behavior. For example, you can specify the directories you want to be accessible, the content that should be served, and so on.
When you are done configuring Nginx, you’ll need to restart the server for the changes to take effect. To do this, run the following command:
sudo systemctl restart nginx
Once nginx has been restarted, you should be able to access it from your web browser by entering the server’s IP address or domain name.
Step 3: Installing PHP
The next step is to install PHP. To do this, you’ll need to use Yum again. Run the following command to install PHP:
sudo yum install php
Next, you’ll need to install the required PHP modules. The php-fpm module is used to run PHP scripts. To install it, run the following command:
sudo yum install php-fpm
Finally, you’ll need to restart the PHP-FPM service for the changes to take effect. To do this, use the following command:
sudo systemctl restart php-fpm
Step 4: Configuring PHP
Now that PHP is installed, you’ll need to configure it. The default configuration file for PHP is located in the /etc/php.ini file. You can edit this file to customize PHP’s behavior. For example, you can specify which modules are enabled, and how much memory is allocated for each script.
Once you have finished configuring PHP, you’ll need to restart the PHP-FPM service for the changes to take effect. To do this, run the following command:
sudo systemctl restart php-fpm
Step 5: Connecting Nginx and PHP
The last step is to connect Nginx and PHP. This is done by adding a configuration directive in the /etc/nginx/conf.d/php-fpm.conf file. This directive tells Nginx where to send processed PHP scripts. You can add the following directive to the file:
location ~ .php$ {
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
}
Once you have added this directive, you’ll need to restart Nginx for the changes to take effect. To do this, run the following command:
sudo systemctl restart nginx
