CentOS is a free and open source operating system commonly used in server environments. In a server environment, it is often necessary to install open source software such as Apache, PHP, and MySQL to build web servers and database servers. In this article, we will explain how to install Apache, PHP 5.2.0 and MySQL in CentOS.
Install Apache
The software package source in CentOS is managed using the yum command. Before installing Apache, make sure that yum has been updated to the latest version:
sudo yum update
Then, the command to install Apache is as follows:
sudo yum install httpd
After the installation is complete, start Apache and use the following command:
sudo systemctl start httpd.service
You can also set Apache to start automatically at boot:
sudo systemctl enable httpd.service
At this time, enter the IP address or domain name of the server in the browser to access the default Apache welcome page.
Install MySQL
The MySQL software package source in CentOS can also be installed using the yum command. The command is as follows:
sudo yum install mysql-server
After the installation is completed, start the MySQL service and use the following command :
sudo systemctl start mysqld.service
For security reasons, you can execute the following command to perform MySQL security settings:
sudo /usr/bin/mysql_secure_installation
During the security setting process, you need to set the MySQL root user password and prohibit root users from logging in remotely.
Install PHP 5.2.0
In CentOS 7, the default version of PHP is 5.4.16, but some applications require earlier versions. This article describes how to install PHP 5.2.0 version.
EPEL (Extra Packages for Enterprise Linux) is a software package repository for enterprise-level Linux systems. To install PHP 5.2.0, you need to install the EPEL repository first. Enter the following command in the terminal:
sudo yum install epel-release
webtatic is a third-party CentOS software package repository that provides some software that is not in the official CentOS source. . Use the following command to add the webtatic repository:
sudo rpm -ivh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Use the following command to install PHP 5.2.0:
sudo yum install php52w php52w-cli php52w-common php52w-devel php52w-gd php52w-mbstring php52w-mcrypt php52w-mysql php52w-pear php52w-xml
After installation is complete , restart the Apache and MySQL services, and restart the server.
sudo systemctl restart httpd.service sudo systemctl restart mysqld.service sudo reboot
After the installation is complete, you can view the PHP version information in phpinfo().
