Installing latest version of WordPress script
A LAMP (Linux, Apache, MariaDB, PHP) stack is commonly used to prepare servers for hosting web content. This detailed guide will come in handy if you are planning to manage the server without a cPanel (control panel) installed. We will show how to install LAMP on the server with AlmaLinux 8 and AlmaLinux 9. Unfortunately, we do not provide technical assistance with VPS/Dedicated Servers without cPanel. However, this detailed guide will be useful if you are planning to manage the server without a cPanel (control panel) installed.
AlmaLinux 8 and 9 use the package manager
dnf by default. It has been developed as a successor for yum and resolves issues with poor performance, excessive memory usage, slowdown for dependency resolution, etc.
In this guide we will
set up recent versions of Apache, MariaDB, and PHP on a server with the
hostname server1.ncsupport.info. Additionally, we will set up a basic configuration of LAMP to host a
WordPress content management system and install its latest version at
http://domain.tld/.
- AlmaLinux 8 or AlmaLinux 9 blank version. If you have a VPS with us, one of these operating systems can be installed using your access to
the SolusVM management tool.
- Internal server account with root access (#) or the one with sudo privileges. For simplicity, the following steps will be illustrated using the “root” account. Therefore, commands to be executed starting with the “#” sign, which should not be copied.
We recommend updating the operating system (OS) before proceeding with further steps.
dnf clean all
dnf update
If you see Complete! at the end when running the yum update, everything is good to go.
It may be required to review and confirm/deny certain changes during the process. To answer “Yes” automatically, you can use the option “-y” with “dnf -y update”.
Another optional step is to reboot the server and check its current configuration.
reboot
uname -r
cat /etc/redhat-release
httpd -v
mysql -V
php -v
Above is a simple confirmation that our test environment does not have any Apache, MariaDB and PHP modules installed yet.
The process is as simple as running a single command below:
yum install -y httpd httpd-tools
This time we need to edit the main Apache configuration file and finally start it. We will use the text editor "
nano" but you can use any other of your choice.
dnf -y install nano
Apache main configuration file is /etc/httpd/conf/httpd.conf. Therefore, we can open it using the following command:
nano /etc/httpd/conf/httpd.conf
Use keyboard arrows to scroll down the file. The section you need is Main server configuration. Change two lines: ServerAdmin and ServerName. ServerAdmin can be any email address you wish to send server notifications to. ServerName should be the hostname you set with HTTP port 80. Make sure that there is no comment (# sign) at the beginning of either ServerAdmin or ServerName lines.
We are ready to start the Apache server and enable its autoloading during the server startup.
systemctl start httpd
systemctl enable httpd
In case a domain name is pointed to the server you can check the Apache start page. (Visiting http://ncsupport.info/ also works.) Feel free to use your own domain name. Alternatively, you should be able to see the start page of the Apache server when entering the IP address of the server in your web browser.
If you do not remember the IP address assigned to the server, this command will come in handy:
ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'
Configuring firewall daemon
AlmaLinux comes bundled with a default firewall that is why AlmaLinux –
firewalld. It provides a dynamically-managed firewall with support for network/firewall zones to define the trust level of network connections or interfaces.
If the server environment is fresh, the firewall is deactivated by default. Let’s start the service, enable its autostart, and allow incoming TCP traffic to ports 80 (HTTP), 443 (HTTPS). We will use the firewall-cmd utility for such a configuration.
firewall-cmd --state
systemctl start firewalld
systemctl enable firewalld
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload
NOTE: Any changes to the firewalld configuration require its reload.
Step 2. MariaDB
Installation
On AlmaLinux 8 and 9, it is recommended to install the native
MariaDB
package instead of standard MySQL. The goal for MariaDB is for it to be a drop-in replacement for MySQL, with more features and better performance:
dnf install -y mariadb-server mariadb
mysql -V
Similar to other services, MariaDB has to be started. Having it auto-started will come in handy here as well:
systemctl start mariadb
systemctl enable mariadb
Running the initial secure configuration script
The MariaDB server comes with a security script that should be run as a part of the initial configuration. The script will go through the reset of MariaDB's own root password, removal of anonymous users and the test database, as well as the disabling of remote root login, etc.
mysql_secure_installation
In the end, you should see the message: Thanks for using MariaDB!.
Logging into MariaDB and creating the basic database
You can launch the MariaDB command line interface using this command:
mysql -u root -p
The prompt will request a password. It must be the one that has just been set for root database access after going through the secure installation script. Afterward, the command line will allow us to manage the MariaDB server. Let’s create a basic database named “foo_db” and grant full access to this database for the MariaDB user “foo_user” with the password “foo_password”:
MariaDB> CREATE DATABASE foo_db; GRANT ALL ON foo_db.* TO 'foo_user'@'localhost' IDENTIFIED BY 'foo_password';
You can double-check the list of existing databases with “show databases;” prior to leaving the MySQL/MariaDB server with “quit.”
Step 3. PHP
Installing the recent PHP version
Although it’s possible to install PHP with “dnf install php”, you will get the outdated PHP 7.2 only. This version is far behind today’s
active support time frames for PHP
and is not considered as secure.
Instead, we will focus on the most recent PHP environment version, 8.3. Side note:
developers of WordPress recommend the use of PHP 7.4 or above.
To get up-to-date versions of PHP, we will need to to install extra repositories:
Extra Packages for Enterprise Linux
(EPEL) and
Remi's RPM repository:
dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
For AlmaLinux 8:
dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
For AlmaLinux 9:
dnf -y install https://rpms.remirepo.net/enterprise/remi-release-9.2.rpm
Continue with the following for both systems:
dnf -y install yum-utils
dnf module reset php
dnf module install php:remi-8.3
dnf -y update
dnf -y install php
php -v
Adding the most common PHP extensions
PHP 8.3 itself is not enough. For instance, WordPress requires at least
14 essential PHP extensions. In other words, you will need to double-check the presence of these and a few other popular PHP extensions with the following command (missing extensions will get installed):
dnf -y install curl php-dom php-gd php-hash php-imagick php-json php-ldap php-mbstring php-mysql libsodium php-odbc php-openssl php-pcre php-pdo php-pear php-soap php-xml php-xmlrpc php-zip
Step 4. Testing LAMP
At this point, the LAMP stack is set up and ready to resolve content on the Internet. You can rerun our initial checks from the “
Prerequisites” section of this article. Additionally, we will reboot the server to make sure that all changes are applied.
reboot
uname -r
cat /etc/redhat-release
httpd -v
mysql -V
php -v
By default, the server is set up to resolve the content of /var/www/html/ when accessed via IP address or the server’s domain name. To test this, let’s create a simple index.html file:
nano /var/www/html/index.html
My website on CentOS
A simple index.html file
Test page for ncsupport.info
