In the current Internet era, building a stable and efficient server has become the need of more and more people. Among the many server frameworks, PHP and Linux servers have become the most mainstream choices. Let's discuss how to use PHP and Linux to build a stable and efficient server to meet daily needs.
1. Install and configure the Linux system
First we need to install the Linux system on the server. Common Linux operating systems include: Ubuntu, CentOS, Debian, etc. We need to understand our needs before choosing an operating system.
After installation, we need to perform basic configuration of the Linux operating system. For example, install necessary software, update security patches, modify IP addresses, etc.
2. Install and configure the Apache server
The Apache server is one of the most popular web server applications. It supports PHP and is open source and has high stability. We can install Apache through the command:
sudo apt-get update
sudo apt-get install apache2
After the installation is complete, we need to start the Apache service and perform basic configuration on it. For example, configure the firewall, modify the default port, prevent DDoS attacks, etc. Here we only talk about the most basic configuration, that is, changing the Apache root directory so that it can correctly process PHP files.
Open the Apache configuration file
sudo vim /etc/apache2/apache2.conf
Find the following content:
Options Indexes FollowSymLinks AllowOverride None Require all granted
is changed to
Options Indexes FollowSymLinks AllowOverride All Require all granted
Restart the Apache service after the modification is completed
sudo service apache2 restart
3. Install PHP
PHP can be installed directly through the apt-get command
sudo apt-get install php libapache2-mod-php
After the installation is complete we need to configure PHP to interact with the Apache server. We need to modify the Apache configuration file.
sudo vim /etc/apache2/mods-enabled/dir.conf
Put index.html in DirectoryIndex in front, as shown below
DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm
Restart the Apache service after the modification is completed
sudo service apache2 restart
4. Set up the database environment
Installing the MySQL database in the server and connecting PHP to the database can make it easier for us to store and manage data. We can install MySQL through the following command
sudo apt-get install mysql-server
After the installation is complete, we need to modify the MySQL configuration file to increase its security. For example, changing the password of the root user, restricting remote access, etc. Here we only describe how to create a new MySQL user
Enter the MySQL console
mysql -u root -p
Execute the following command to create a new database and user
CREATE DATABASE mydatabase;
CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword';
GRANT ALL PRIVILEGES ON mydatabase.* TO 'myuser'@'localhost';
FLUSH PRIVILEGES;
After the modification is completed, we need to restart the MySQL service
sudo service mysql restart
5. Summary
Use PHP and Linux to build a server and Basic configuration is very simple, but to achieve an efficient and stable level requires more experience and skills. During use, we should pay attention to safety and maintainability, and maintain the stability and update of the system to better meet our needs. Therefore, for beginners, it is recommended to try more and summarize more during the learning process to continuously improve their skill level.
