Install LAMP on CentOS 7 with PHP 5.4/7.0/7.1/7.2/7.3/7.4 Rumi, October 26, 2020 Preliminary Note In this tutorial, I use the hostname server1.example.com with the IP p 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate. I will add the EPEL repo here to install latest phpMyAdmin as follows: rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY* yum -y install epel-release To edit files on the shell, I’ll install the nano editor. If you prefer vi for file editing, then skip this step. yum -y install nano Installing MySQL / MariaDB MariaDB is a MySQL fork of the original MySQL developer Monty Widenius. MariaDB is compatible with MySQL and I’ve chosen to use MariaDB here instead of MySQL. Run this command to install MariaDB with yum: yum -y install mariadb-server mariadb Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server: systemctl start mariadb.service systemctl enable mariadb.service Set passwords for the MySQL root account: mysql_secure_installation [root@server1 ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): <--ENTER OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] New password: <--yourmariadbpassword Re-enter new password: <--yourmariadbpassword Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] <--ENTER ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] <--ENTER ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] <--ENTER - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] <--ENTER ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB! [root@server1 ~]# Installing Apache CentOS 7 ships with Apache 2.4. Apache is directly available as a CentOS 7 package, therefore we can install it like this: yum -y install httpd Now configure your system to start Apache at boot time… systemctl start httpd.service systemctl enable httpd.service To be able to access the webserver from outside, we have to open the HTTP (80) and HTTPS (443) ports in the firewall. The default firewall on CentOS is firewalld which can be configured with the firewalld-cmd command. firewall-cmd --permanent --zone=public --add-service=http firewall-cmd --permanent --zone=public --add-service=https firewall-cmd --reload Now direct your browser to the IP address of your server, in my case http://192.168.0.100, and you should see the Apache placeholder page: Installing PHP The PHP version that ships with CentOS as default is quite old (PHP 5.4). Therefore I will show you in this chapter some options to install newer PHP versions like PHP 7.0 to 7.3 from Remi repository. Add the Remi CentOS repository. rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm Install yum-utils as we need the yum-config-manager utility. yum -y install yum-utils and run yum update yum update Now you have to chose which PHP version you want to use on the server. If you like to use PHP 5.4, then proceed to chapter 4.1. To install PHP 7.0, follow the commands in chapter 4.2, for PHP 7.1 chapter 4.3, for PHP 7.4 use chapter 4.4 and for PHP 7.3 follow chapter 4.5 instead. Follow just one of the 4.x chapters and not all of them as you can only use one PHP version at a time with Apache mod_php.Advertisement Install PHP 5.4 To install PHP 5.4, run this command: yum -y install php Install PHP 7.0 We can install PHP 7.0 and the Apache PHP 7.0 module as follows: yum-config-manager --enable remi-php70 yum -y install php php-opcache Install PHP 7.1 If you want to use PHP 7.1 instead, use: yum-config-manager --enable remi-php71 yum -y install php php-opcache Install PHP 7.2 If you want to use PHP 7.2 instead, use: yum-config-manager --enable remi-php72 yum -y install php php-opcache Install PHP 7.3 If you want to use PHP 7.3 instead, use: yum-config-manager --enable remi-php73 yum -y install php php-opcache In this example and in the downloadable virtual machine, I’ll use PHP 7.3. We must restart Apache to apply the changes: systemctl restart httpd.service Getting MySQL Support In PHP To get MySQL support in PHP, we can install the php-mysqlnd package. It’s a good idea to install some other PHP modules as well as you might need them for your applications. You can search for available PHP5 modules like this: yum search php Pick the ones you need and install them like this: yum -y install php-mysqlnd php-pdo In the next step I will install some common PHP modules that are required by CMS Systems like WordPress, Joomla, and Drupal: yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-soap curl curl-devel Now restart Apache web server: systemctl restart httpd.service phpMyAdmin installation phpMyAdmin is a web interface through which you can manage your MySQL databases. phpMyAdmin can now be installed as follows: yum -y install phpMyAdmin Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <RequireAny> stanza and adding the ‘Require all granted’ line): nano /etc/httpd/conf.d/phpMyAdmin.conf [...] Alias /phpMyAdmin /usr/share/phpMyAdmin Alias /phpmyadmin /usr/share/phpMyAdmin <Directory /usr/share/phpMyAdmin/> AddDefaultCharset UTF-8 <IfModule mod_authz_core.c> # Apache 2.4 # <RequireAny> # Require ip 127.0.0.1 # Require ip ::1 # </RequireAny> Require all granted </IfModule> <IfModule !mod_authz_core.c> # Apache 2.2 Order Deny,Allow Deny from All Allow from 127.0.0.1 Allow from ::1 </IfModule> </Directory> <Directory /usr/share/phpMyAdmin/> Options none AllowOverride Limit Require all granted </Directory> [...] Restart Apache to apply the configuration changes: systemctl restart httpd.service Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/ Src: https://www.howtoforge.com/tutorial/centos-lamp-server-apache-mysql-php/ Administrations Collected Articles Configurations (Linux) CentOS 7LAMPPHP 7.0PHP 7.1PHP 7.2PHP 7.3PHP 7.4
