Note : These instructions apply to RedHat version 8. They have also been found to work for RedHat 9.0 and for Fedora Core 1 and 2. Fedora Core 3 requires the php-gd package in addition to php. I see no reason why they should not work for later versions, but....
{{Note|This document is about installing Moodle 3.7 in an RedHat Enterprise Linux (RHEL) 8}}


Redhat installation considerations: There are many installation options available when installing Redhat. I assume that you are installing on a server and will have selected a Server type install. There is however no reason why this should not work on a desktop or Workstation installation.
== Server Installation ==
* Web Server
** Moodle 3.7 needs PHP 7.1; RHEL8 comes with PHP 7.2.[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/8.0_release_notes/index#web-servers-databases-dynamic-languages]
* Database
** Moodle 3.7 needs MariaDB 5.5 or MySQL 5.6; RHEL8 comes with MariaDB 10.3 and MySQL 8.0 (They cannot be installed at the same time).[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/deploying_different_types_of_servers/index#using-mariadb]
* BEWARE OF the 'Server with a GUI' option, it may not work as expected.
 
Note: Set up the firewall if necessary. You probably only need to enable HTTP/HTTPS (and perhaps FTP and SSH) access to your server machine, unless you know the difference.
 
== Network Interface ==


== Make sure you have installed the following packages ==
During installation, under "System" -> "Network & Host Name", remember to enable the NIC. It's not enabled by default.
(You will need to select the option to customize the default set of packages on installation OR bring up the package manager by putting disk 1 back in the drive for an existing system):


* X Windows System (not vital but easier)
== Configure hostname and domain name==
* Gnome or KDE desktop environment (as above)
 
* Server Configuration Tools
Type system-config-network to open the GUI editor.  Click on the DNS tab. In the "DNS Search Path" fill in your domain name for example myuniversity.edu. Now ensure the "Hostname" contains the computer name you will use and click activate to make changes
* Web Server
 
** Click "Details" and make sure all PHP modules are ticked (except ODBC and PGSQL, they're not neccesary)
== System Registration ==
** make sure not to miss the MYSQL-PHP module (not installed by default)
* To receive package updates, create a user account at redhat.com, and then login and register as developer at https://developers.redhat.com/
* SQL Database
* Subscribe the system by:
** Click "Details" and tick MySQL server box
<pre>
* Also make sure you set up the firewall. You probably only need to enable HTTP (and perhaps FTP and SSH) access to your server machine, unless you know different.
subscription-manager register --auto-attach
</pre>
Enter the username and password as requested.
* Update the system and then reboot
<pre>
yum update
reboot
</pre>
See [https://developers.redhat.com/rhel8/install-rhel8-vbox/]
 
== SELinux ==
Default RedHat Enterprise Linux comes with SELinux set to 'enforcing'. But this may cause user problem accessing web content placed at directory other than the default directory (/var/www/html) or other access problem. If you are not used to SELinux and setting permissions, it's (maybe less secure but) often easier to lower the SELinux level to 'permissive' or even 'disabled'.
 
<pre>
# vi /etc/sysconfig/selinux
 
SELINUX=disabled
</pre>
 
See the CentOS [https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security-Enhanced_Linux/sect-Security-Enhanced_Linux-Working_with_SELinux-Changing_SELinux_Modes.html]
 
== Firewall ==
The internal firewall (RHEL since version 7 uses 'firewalld'[https://firewalld.org/]) is on by default. It will block the access to the web server. You may stop it first to test connection:
 
<pre>
service firewalld stop
</pre>
 
and then either disable it:
 
<pre>
chkconfig firewalld off
</pre>
 
or enable permanent HTTP access to it, you may want to enable HTTPS as well:
<pre>
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
</pre>
 
Restart the firewall and then check the allow status:
<pre>
service firewalld restart
firewall-cmd --zone=public --list-services
</pre>
 
To use iptables instead of firewalld, see [https://access.redhat.com/solutions/1264743]
 
== MariaDB / MySQL ==
 
* Make sure at least 'mariadb' and 'mariadb-server' packages are installed.
** (use "mysql" and "mysql-server" for MySQL)
<pre>
yum install mariadb mariadb-server
</pre>
*Then get the daemon running, it is not running by default. And set it to auto-start. See also [https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/selinux_users_and_administrators_guide/chap-managing_confined_services-mariadb]
** (use "mysqld" for MySQL)
<pre>
service mariadb start; chkconfig mariadb on
</pre>
*Edit /etc/my.cnf (May be different for MySQL) (MariaDB 10.3 doesn't need this as these are already the default settings.)
 
<pre>vi /etc/my.cnf</pre>
 
Scroll down to the [mysqld] section and under "Basic Settings", add the following line under the last statement.
 
<pre>innodb_file_format = Barracuda</pre><br />
<pre>innodb_file_per_table = 1</pre><br />
<pre>innodb_large_prefix</pre>
 
* If you haven't yet, as root, change the MariaDB/MySQL root password, also secure the installation
** mysql_secure_installation
* Next, set up the MariaDB/MySQL database (see http://moodle.org/doc/?file=install.html#Database for more details)
* Launch MariaDB/MySQL as root
** mysql -u root -p
*** (at the password prompt, enter the password from above)
* At the '>' MariaDB/MySQL prompt, enter the following commands (MariaDB/MySQL commands are ended with a ';')
** CREATE DATABASE mymoodle CHARSET 'utf8mb4';
*** ('mymoodle' is the name of the database you would like to use, it will be entered to the Moodle 'config.php' later)
** GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON mymoodle.* TO moodleuser@localhost IDENTIFIED BY 'moodlepass';
*** (as above, 'mymoodle', 'moodleuser' and 'moodlepass' will be entered to the Moodle 'config.php' later)
** flush privileges;
** quit
* (! Consider MariaDB/MySQL security - not covered here. If you run a firewall, you don't have too much to worry about.)

=== Setting Document Root ===
Edit <pre>/etc/httpd/conf/httpd.conf</pre>
 
Change From: DocumentRoot /var/www/html
 
Change To: DocumentRoot /var/www/html/mymoodle
 
If you want the web site to be served as "http://www.whatever.com/mymoodle" instead of "http://www.whatever.com", don't change it, and modify the 'wwwroot' parameter of Moodle 'config.php' file accordingly.
 
== PHP ==
* Install PHP:
<pre>
yum install php php-cli php-common php-fpm php-gd php-intl php-json php-mbstring php-mysqlnd php-opcache php-pdo php-xml php-xmlrpc php-pecl-zip php-soap
</pre>
 
*Check the installed PHP version:
<pre>
# php -v
</pre>
 
* Restart the web server so that PHP can start working:
<pre>
service httpd restart
</pre>
 
*Create a "phpinfo.php" file within the "/var/www/html" directory (or anywhere the Apache "DocumentRoot" points to) with the following content:
<pre>
<?php
phpinfo();
?>
</pre>
And then open web browser and browse to "http://webserver/phpinfo.php" to make sure PHP is working with the web server. Then remove the file for security reason.
 
<!--RedHat EL - or 'the upstream vendor' if you are using a clone - will not introduce newer PHP packages unless there is an exception (php53 in EL5.6+). Moodle has quite a some PHP dependencies which cannot be fullfilled solely by installing all RHEL-provided packages.
 
You have therefore to make a choice:
* Use RH and pay attention your Moodle version supports it + PHP modules from and maintain them on your own
* Install the whole (latest) PHP from source on your own (and maintain it)
* Install PHP packages from a third party repo (but you won't get support from Redhat if you run into problems):
** [rpms.famillecollet.com] Maintains recent MySQL and PHP packages for supported EL version (a EPEL contributor)
** RPMFusion and others also have newer PHP packages-->
 
== Install Moodle ==
Now everything's ready. Use web browser to open "http://webserver/mymoodle/install.php" to start the installation.
 
== Set up cron job ==
 
As root user edit the /etc/crontab file using vi (or another editor) OR you can add a line to the root user's "personal" crontab (don't do both!).
===CLI version===
{{Note| According to Moodle's documentation, users should use the CLI version if possible, as the web version may be removed in future.[https://docs.moodle.org/36/en/Cron#Working_out_the_Moodle_cron_command]}}
 
* If you wish to place an entry in your root user's crontab use:
** <pre>crontab -e</pre>
** Add the following line:
<pre> */5 * * * * /usr/bin/php /path/to/mymoodle/admin/cli/cron.php</pre>
to run the command every 5 minutes.


* As root user type the command:
===Web version===
{{Note|Use the CLI version if possible.}}
* If you wish to place an entry in your root user's crontab use:
** crontab -e
** crontab -e
* Add the following line (you need to know vi, 'o' adds a line in vi):
** Add the following line:
** */5 * * * /usr/bin/wget -g -O /dev/null http://localhost/mymoodle/admin/cron.php
*** */5 * * * * /usr/bin/wget -O /dev/null http://localhost/mymoodle/admin/cron.php
**** (change the URL as appropriate for your site)
---
* If you wish to add an entry in /etc/crontab:
* Open the /etc/crontab file in an editor (vi).
* Add the following line:
** */5 * * * * root /usr/bin/wget -O /dev/null http://localhost/mymoodle/admin/cron.php
*** (change the URL as appropriate for your site)
*** (change the URL as appropriate for your site)

Note: This document is about installing Moodle 3.7 in an RedHat Enterprise Linux (RHEL) 8


Server Installation

  • Web Server
    • Moodle 3.7 needs PHP 7.1; RHEL8 comes with PHP 7.2.[1]
  • Database
    • Moodle 3.7 needs MariaDB 5.5 or MySQL 5.6; RHEL8 comes with MariaDB 10.3 and MySQL 8.0 (They cannot be installed at the same time).[2]
  • BEWARE OF the 'Server with a GUI' option, it may not work as expected.

Note: Set up the firewall if necessary. You probably only need to enable HTTP/HTTPS (and perhaps FTP and SSH) access to your server machine, unless you know the difference.

Network Interface

During installation, under "System" -> "Network & Host Name", remember to enable the NIC. It's not enabled by default.

Configure hostname and domain name

Type system-config-network to open the GUI editor. Click on the DNS tab. In the "DNS Search Path" fill in your domain name for example myuniversity.edu. Now ensure the "Hostname" contains the computer name you will use and click activate to make changes

System Registration

  • To receive package updates, create a user account at redhat.com, and then login and register as developer at https://developers.redhat.com/
  • Subscribe the system by:
subscription-manager register --auto-attach

Enter the username and password as requested.

  • Update the system and then reboot
yum update
reboot

See [3]

SELinux

Default RedHat Enterprise Linux comes with SELinux set to 'enforcing'. But this may cause user problem accessing web content placed at directory other than the default directory (/var/www/html) or other access problem. If you are not used to SELinux and setting permissions, it's (maybe less secure but) often easier to lower the SELinux level to 'permissive' or even 'disabled'.

# vi /etc/sysconfig/selinux

SELINUX=disabled

See the CentOS [4]

Firewall

The internal firewall (RHEL since version 7 uses 'firewalld'[5]) is on by default. It will block the access to the web server. You may stop it first to test connection:

service firewalld stop

and then either disable it:

chkconfig firewalld off

or enable permanent HTTP access to it, you may want to enable HTTPS as well:

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https

Restart the firewall and then check the allow status:

service firewalld restart
firewall-cmd --zone=public --list-services

To use iptables instead of firewalld, see [6]

MariaDB / MySQL

  • Make sure at least 'mariadb' and 'mariadb-server' packages are installed.
    • (use "mysql" and "mysql-server" for MySQL)
yum install mariadb mariadb-server
  • Then get the daemon running, it is not running by default. And set it to auto-start. See also [7]
    • (use "mysqld" for MySQL)
service mariadb start; chkconfig mariadb on
  • Edit /etc/my.cnf (May be different for MySQL) (MariaDB 10.3 doesn't need this as these are already the default settings.)
vi /etc/my.cnf

Scroll down to the [mysqld] section and under "Basic Settings", add the following line under the last statement.

innodb_file_format = Barracuda


innodb_file_per_table = 1


innodb_large_prefix
  • If you haven't yet, as root, change the MariaDB/MySQL root password, also secure the installation
    • mysql_secure_installation
  • Next, set up the MariaDB/MySQL database (see http://moodle.org/doc/?file=install.html#Database for more details)
  • Launch MariaDB/MySQL as root
    • mysql -u root -p
      • (at the password prompt, enter the password from above)
  • At the '>' MariaDB/MySQL prompt, enter the following commands (MariaDB/MySQL commands are ended with a ';')
    • CREATE DATABASE mymoodle CHARSET 'utf8mb4';
      • ('mymoodle' is the name of the database you would like to use, it will be entered to the Moodle 'config.php' later)
    • GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON mymoodle.* TO moodleuser@localhost IDENTIFIED BY 'moodlepass';
      • (as above, 'mymoodle', 'moodleuser' and 'moodlepass' will be entered to the Moodle 'config.php' later)
    • flush privileges;
    • quit
  • (! Consider MariaDB/MySQL security - not covered here. If you run a firewall, you don't have too much to worry about.)

Setup Moodle

(I will install under /usr/moodle, data in /usr/moodle_data)

Download

  • Download your favourite version of Moodle from moodle.org (.zip archive is easiest)
  • as Root create folder under /usr and copy zip
    • su
    • mkdir /usr/moodle
    • mkdir /usr/moodle_data
    • cp moodle_111.zip /usr/moodle
  • If you prefer you can install the GIT version directly for all the latest features. Instead of downloading and copying the zip file. See Git_for_Administrators for details.
  • Or if you prefer you can install the CVS version directly for all the latest features. Instead of downloading and copying the zip file.
    • cd /usr/moodle
    • cvs -d:pserver:anonymous@uk.cvs.moodle.org:/cvsroot/moodle login
    • cvs -z3 -d:pserver:anonymous@uk.cvs.moodle.org:/cvsroot/moodle co moodle

Unpack and set file permission etc

  • Still as root we unpack moodle and rename to something appropiate (I have multiple moodle installs, hence this setup). I will call this install mymoodle.
    • cd /usr/moodle
    • unzip moodle_xxx.zip
    • mv moodle mymoodle
      • (optional step - I have more than one install under /usr/moodle)
    • mkdir /usr/moodle_data/mymoodle
      • (same name as the moodle install above)
    • chown -R apache:apache /usr/moodle
      • (! Giving Apache full rights to your Moodle programs is not secure. Check out the forums for recomendations on how to secure a production environment.)
    • chown -R apache:apache /usr/moodle_data

Setup config.php

  • Still as root copy and edit the config file, you should know the host/domain name for your server
    • cd /usr/moodle/mymoodle
    • cp config-dist.php config.php
    • vi config.php (or whatever your favourite editor is!)
  • Your config.php settings should be something like...
    • dbtype = 'mariadb' (use 'mysqli' for MySQL)
    • dbhost = 'localhost'
    • dbname = 'mymoodle'
    • dbuser = 'moodleuser'
    • dbpass = 'moodlepass' (<-- better make this something of your own)
    • prefix = 'mdl_'
      • (Use different prefix if there is more than one instance of Moodle on the same server, and you plan to share the database)
    • wwwroot = 'http://myhost.mydomain'
    • dataroot = '/usr/moodle_data/mymoodle'
  • Save your changes and exit from the editor

Apache

  • Install it if it's not installed already.
yum install httpd

or everything

yum install httpd*
  • Start it and make it auto-start after reboot:
service httpd start; chkconfig httpd on
  • Open a web browser and make sure you can connect to the installed web server and default port (80) of the server. If not OK, it may be blocked by the firewall (see above). Correct the problem before continuing.
  • Edit the Apache configuration file
    /etc/httpd/conf/httpd.conf
  • Right at the end of the file add the following lines:
    • <Directory "/usr/moodle/mymoodle"> (the directory used during Moodle installation)
    • DirectoryIndex index.php
    • AcceptPathInfo on
    • AllowOverride None
    • Options None
    • Order allow,deny
    • Allow from all
    • </Directory>
    • Alias /mymoodle "/usr/moodle/mymoodle"
  • Don't insert a space in "allow,deny" (common mistake!)
  • You might also want to run through the rest of the config file and make some other (obvious) changes - administrator email and suchlike. Not vital though.
  • Run the Services application (same as for Mysql) - tick and start "httpd", then save changes and exit.

Setting Document Root

Edit

/etc/httpd/conf/httpd.conf

Change From: DocumentRoot /var/www/html

Change To: DocumentRoot /var/www/html/mymoodle

If you want the web site to be served as "http://www.whatever.com/mymoodle" instead of "http://www.whatever.com", don't change it, and modify the 'wwwroot' parameter of Moodle 'config.php' file accordingly.

PHP

  • Install PHP:
yum install php php-cli php-common php-fpm php-gd php-intl php-json php-mbstring php-mysqlnd php-opcache php-pdo php-xml php-xmlrpc php-pecl-zip php-soap
  • Check the installed PHP version:
# php -v
  • Restart the web server so that PHP can start working:
service httpd restart
  • Create a "phpinfo.php" file within the "/var/www/html" directory (or anywhere the Apache "DocumentRoot" points to) with the following content:
<?php
phpinfo();
?>

And then open web browser and browse to "http://webserver/phpinfo.php" to make sure PHP is working with the web server. Then remove the file for security reason.


Install Moodle

Now everything's ready. Use web browser to open "http://webserver/mymoodle/install.php" to start the installation.

Set up cron job

As root user edit the /etc/crontab file using vi (or another editor) OR you can add a line to the root user's "personal" crontab (don't do both!).

CLI version

Note: According to Moodle's documentation, users should use the CLI version if possible, as the web version may be removed in future.[8]
