How to Install Tiki Wiki with Apache and Let's encrypt SSL on Debian 10

TikiWiki is a free and open-source content management system written in PHP language. It is is very powerful, full-featured and can be used to create websites, wikis, Web applications, knowledge-base, portals, image galleries and many more.

TikiWiki comes with a rich set of features, including, Forums, Blog, Maps, Workspace, Slideshow, Shopping Cart, Bug and issue tracker, Multilingual, File and image gallery, Events and many more.

In this tutorial, we will learn how to install TikiWiki CMS on Debian 10.

Requirements

  • A server running Debian 10.
  • A root password is set up to your server.

Getting Started

Before starting, you will need to update your system with the latest version. You can do this by running the following command:

apt-get update -y
apt-get upgrade -y

Once your server is updated, restart your server to apply the changes.

Install LAMP Server

TikiWiki runs on Apache / Nginx web server, written in PHP language and use MariaDB/MySQL to store its data. So you will need to install Apache, MariaDB, PHP and other required extensions on your server. First, install Apache and MariaDB server with the following command:

apt-get install apache2 mariadb-server unzip -y

By default, Debian 10 ships with PHP version 7.3. But, TikiWiki does not support PHP 7.3. So, you will need to install PHP 7.2 and other required extensions.

To add SURY repository, first download and GPG key with the following command:

wget https://packages.sury.org/php/apt.gpg
apt-key add apt.gpg

Next, add the SURY repository to APT with the following command:

echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | tee /etc/apt/sources.list.d/php.list

Next, update the repository and install PHP7.2 along with all required extensions with the following commands:

apt-get update -y
apt-get install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-sqlite3 php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-xml php7.2-cli php7.2-zip -y

After installing PHP7.2, open php.ini file and tweak some settings:

nano /etc/php/7.2/apache2/php.ini

Add the following lines:

memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = Asia/Kolkata

Save and close the file when you are finished. Then, proceed to the next step.

Create Database for TikiWiki

By default, MariaDB is not secured. So, you will need to secure it first. You can secure it with the following script:

mysql_secure_installation

You should answer all the questions as shown below:

    Enter current password for root (enter for none):
    Set root password? [Y/n]: N
    Remove anonymous users? [Y/n]: Y
    Disallow root login remotely? [Y/n]: Y
    Remove test database and access to it? [Y/n]:  Y
    Reload privilege tables now? [Y/n]:  Y

Once MariaDB is secured, login to MariaDB shell:

mysql -u root -p

Provide your root password when prompt then create a database and user for TikiWiki with the following command:

MariaDB [(none)]> CREATE DATABASE tikidb;
MariaDB [(none)]> CREATE USER 'tiki'@'localhost' IDENTIFIED BY 'password';

Next, grant all the privileges to TikiWiki Database with the following command:

MariaDB [(none)]> GRANT ALL ON tikidb.* TO 'tiki'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;

Next, flush the privileges and exit from the MariaDB shell with the following command:

MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;

Once you have done, you can proceed to the next step.

Download TikiWiki

First, you will need to download the latest version of TikiWiki from the Sourceforge website. You can download it with the following command:

cd /var/www/html/
wget https://sourceforge.net/projects/tikiwiki/files/latest/download -O tikiwiki.zip

Once the download is completed, unzip the downloaded file with the following command:

unzip tikiwiki.zip

Next, rename the extracted directory to tikiwiki with the following command:

mv tiki-20.0 tikiwiki

Next, give proper permissions to the tikiwiki directory with the following command:

chown -R www-data:www-data /var/www/html/tikiwiki/
chmod -R 755 /var/www/html/tikiwiki/

Once you have finished, you can proceed to the next step.

Configure Apache for TikiWiki

Next, you will need to create an Apache virtual host configuration file for TikiWiki. You can create it with the following command:

nano /etc/apache2/sites-available/tikiwiki.conf

Add the following content:

<VirtualHost *:80>
     ServerAdmin [email protected]
     DocumentRoot /var/www/html/tikiwiki
     ServerName example.com

     <Directory /var/www/html/tikiwiki/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/tikiwiki_error.log
     CustomLog ${APACHE_LOG_DIR}/tikiwiki_access.log combined

</VirtualHost>

Save and close the file. Then, enable the virtual host configuration file with the following command:

a2ensite tikiwiki.conf

Finally, enable Apache rewrite module and restart Apache service to reload the configuration changes with the following command:

a2enmod rewrite
systemctl restart apache2

Secure TikiWiki with Let’s Encrypt

In this section, we will explain how to secure your TikiWiki site with Let’s Encrypt free SSL.

First, you will need to install Certbot tool to download and install Let’s Encrypt free SSL for your website. By default, the latest version of Certbot is not available in the Debian 10 default repository. So, you will need to add Certbot repository to your system.

You can add the Certbot repository with the following command:

apt-get install software-properties-common
add-apt-repository ppa:certbot/certbot

Next, update the repository and install Certbot with the following command:

apt-get update -y
apt-get install certbot python-certbot-apache -y

Once installed, create a well-known.conf file for Let’s Encrypt to validate your domain.

First, create a .well-known directory and give proper permissions:

mkdir -p /var/lib/letsencrypt/.well-known
chgrp www-data /var/lib/letsencrypt
chmod g+s /var/lib/letsencrypt

Next, create a well-known.conf file with the following command:

nano /etc/apache2/conf-available/well-known.conf

Add the following lines:

Alias /.well-known/acme-challenge/ "/var/lib/letsencrypt/.well-known/acme-challenge/"
<Directory "/var/lib/letsencrypt/">
    AllowOverride None
    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
    Require method GET POST OPTIONS
</Directory>

Save and close the file. Then, enable the required modules with the following command:

a2enmod ssl
a2enmod http2
a2enmod headers
a2enconf well-known

Next, restart Apache service to apply all the configuration changes:

systemctl restart apache2

Now, let's start to install the free SSL certificate for your domain example.com with the following command:

certbot --apache -d example.com

First, you will need to provide a valid email address and agree to the terms of service as shown below:

   Your key file has been saved at:
   /etc/letsencrypt/live/example.com/privkey.pem
   Your cert will expire on 2019-10-22. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:
   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le
